Blueberry Streusel Bars with Lemon-Cream Filling are a foolproof recipe, made especially to persuade the dessert averse. These tempting bars highlight the addictive balance of tart and sweet – crunchy and chewy when it comes to indulging in a sweet treat.
Blueberry Streusel Bars with Lemon-Cream Filling Recipe
If you too adore the glorious combination of citrus and berry, this Blueberry Streusel Bar recipe needs a permanent spot in your dessert rotation. Wherever I’ve carted it, recipe requests followed. Friends have asked for a few bars to take on plane rides, and it’s always in great demand for picnics. Not only are these bars a hit for all occasions, the deliciousness you’re going to experience with every bite makes this a recipe to share with everyone. It’s hands down one of my favorite treats to bake and worth the little bit of extra effort required.
Lemon and blueberry are like chocolate and vanilla, they just go together. Blueberry desserts are lovely, but sometimes lack-luster, until the addition of an acid like lemon are introduced. The acid complements the rather blandness of the berry and is what makes the lemon-blueberry combination so outstanding, refreshing and makes you unable to stop at just one. Ordinary blueberry desserts snap to attention at the addition of lemon, it’s always a win-win.

The recipe itself is unique with the blueberries sitting on top of a well-made crust covered generously with lemon cream. The flavor will be incomparable to other blueberry bars you might have tasted or baked yourself. No surprises if you decide to put these on repeat in the near future. So from one cook to another, there is no excuse not to try this wonderful springtime union of flavors. After all, this is a marriage that works.

- Studies have shown blueberries reduce DNA damage.
- Reduction of a predominant risk factor for heart disease by preventing oxidative damage to “bad” LDL cholesterol.

If you’re going to have dessert, you might as well make it one that is full of blueberries.
Ingredients for Blueberry Streusel Bars with Lemon-Cream Filling
Pantry Ingredients
- all-purpose flour, make sure it’s fresh
- old-fashioned oats, you do not want quick cooking oats for this recipe
- light brown sugar, dark brown sugar would be overpowering in this recipe
- table salt
- baking powder, make sure it’s fresh
- sweetened condensed milk
Fresh Ingredients
- unsalted butter ~ make sure it’s room temperature
- large egg, separate the yolk from the white
- lemon zest and lemon juice, make sure to zest the lemon before juicing it
- fresh blueberries and they should be room temperature
How To Make Blueberry Streusel Bars
- Combine dry ingredients such as, all-purpose flour, old-fashioned rolled oats, golden brown sugar, salt and baking powder.
- Using your fingers, blend the butter completely into the flour mixture. When finished, transfer two cups of the crumb mixture to another bowl and reserve for the topping.
- With a wooden spoon, blend the egg white into the remaining crumbs.
- Line a metal baking pan with foil, leaving a 1-inch overhang on the ends. Lightly butter the sides and the bottom of the foil.
- Press the egg white-crumb mixture into the bottom of the pan to form a level crust. Bake the crust for 10-12 minutes and remove.
- To make the lemon cream, whisk together sweetened-condensed milk, fresh lemon juice, lemon zest and egg yolk. Let stand for 5 minutes as it thickens.
- Place the blueberries over the hot crust and spoon lemon cream mixture over the blueberries. Spread the cream carefully with a spatula to distribute while taking care to not crush the berries. Bake for 8 minutes.
- Remove from the oven and sprinkle reserved topping over the lemon-blueberry layer, pressing the streusel between your fingers into small lumps as you sprinkle. Bake until the edges are bubbling, about 30 minutes.
- Let the bars cool in the pan on a rack until just warm, about an hour. Carefully lift them out of the pan with the foil overhang and transfer to a wire rack to cool completely.
- Remove foil and cut into 24 bars.
Recipe Tips For The BEST Outcome
- believe or not, this recipe is exceptionally forgiving so don’t be afraid to mess up!
- make sure butter and egg are room temperature before starting
- use room-temperature berries `cold fruit straight from the refrigerator will prevent your dessert from baking evenly
- wait until mostly cooled before lifting out of the pan and completely cooled before slicing
How Should I Store Blueberry Streusel Bars?
Once the bars are completely cool, slice them into squares. After enjoying a few, refrigerate them up to a week in a tightly fitted container. Pop them in the microwave if they are chilled to enjoy them warm.

if you freeze the blueberries beforehand and keep them frozen until the last possible minute, that purplish, bluish bleeding of the blueberries will not happen, they will just be perky and beautiful

Laura says
These look fabulous–loads of streusel, which I love. I like the egg white also to help bind the bottom–I hate it when that layer falls apart.
When Ike hit Ohio and we lost power I spent the majority of the 22 hours freaking out about my blueberries that I had frozen from this summer.
Mrs. L says
You now have me crying that I didn’t freeze some of the wonderful blueberries I was finding at the farmers market. I talked to her yesterday…she said they will be back in July. JULY! Sigh…but I will file this away to make then.

Dr. John says
Another recipe added to my growing file. They looked so good.
Susan at Sticky,Gooey,Creamy,Chewy says
Ack! It looks so good, I can’t even look at it! I’m shielding my eyes now. I can’t make this. No. No. No. I can’t. Don’t make me! I will not spend $4.00/half pint of blueberries to make this. I. Will. Not.
Oh, WTF! I’ll see you later. I’ve got to go to the store now.

Wow that looks good! Can’t wait to try! love blueberries & lemon together! not enough exclamation points in the world for this one!

I love the way your photos with the ingredients look. It totally reminds me of home ec.
Kate says
Oh, Lord. I think that if I make these, my husband will fall in love with me all over again.
Ok. Wish me luck!
Amber says
The last 3 photos are too funny, it is like they are taking over the world and multiplying. For my first Daring Bakers challenge I made the danish with blueberries and lemon cream so I know these are luscious. The 2 flavors work so well together. The frozen lemon mousse was actually for a family birthday party for 36 people in Napa and it was wonderful. I had been testing it beforehand and was gone for 5 days working on the party.
Erin says
I’ve got to make these. And also, I love how you photograph your ingredients. Why does that make it so much more enticing?? I’m not sure but I need to do it, too! There’s something so exciting about the potential of all those separate ingredients.
Psychgrad says
These look delicious. Right up my alley. Starred!
Bunny says
These are beautiful! I love your pictures!!
magpie says
Wow. That sounds perfect.
Suzette says
Those look amazing. I fell in love with blueberries while camping in Maine. Are there blueberries in Oregon? I know you’ll have lots of blackberries there. Maybe blueberries, too?
Gotta try this one soon.
Susan says
All of a sudden I am instantly addicted to blueberries. I just wish I could cook decently.
Your recipes and pictures are enough to make me… ummm… well… pay someone to cook for me, lol.
Debbie in CA : ) says
Aaaaahhhhhh! That’s more like it. I popped on earlier for a quick peek as I try to ease back into the blogging scene after several days away — a BIG chore, by the way — and saw the horse pucky post. YUCK!!! I was so astonished (and exhausted from doing mountains of laundry that no one could tackle while I was away) that I just ran away in disgust (not at you, dear friend, but at those horse-manure-neglecting ones).
Now that my evening has become my own (sort of … ) I popped back on to see what you had for me today. OH JOY! FOOD! GLORIOUS FOOD! And blue berries, no less! I dance, I sing, I send yet another recipe to the printer. As I am smiling and dancing around I realize I went to the market today to replenish the larder and passed up the blueberries as a bit too pricey for this week. UGH!!! So … should I file the recipe for later or run out to the store first thing tomorrow? Hmmmmm …
; )
stinkypaw says
You and me both, share a love for the blueberries!
rachel says
Oh my stars woman!!
I love blueberries!! I cannot wait to make this!
Nom Nom Nom!!!
This looks positively heavenly.
Lore says
A berry addiction is always a healthy one ;). Love the look of these bars!
robinsue says
The oatmeal and blueberry combo stole my heart. And the lemon cream, drool. These look perfect!
grace says
dang it, cathy! this is exactly what i don’t want to see when all i have for breakfast is cereal. thanks a lot.
oh, i can’t stay mad at you. what an incredible treat. đŸ™‚
Cass says
I made these this morning with Lexi strapped to my in the Moby wrap and at one point I’m pretty sure she was drooling for a bite…silly girl those are all for Mommy đŸ™‚
Ava says
I am not a big fan of blueberries, but then I haven’t had them much. They don’t grow here and are very expensive in the supermarkets, often close to $4 for 12 oz. This recipe looks very good and might tempt me to start liking blueberries. Ava
Cathy-wheresmydamnanswer says
These look so good – We love blueberries and are always looking for new ways to incorporate these tasty gems into our diet.. This is a winner đŸ™‚
Sandie says
Yum! I love blueberries, and these bars look so darn good right now. (Is there ever a time when they wouldn’t?)
Lo says
oooh… ahhhh… YUM!!
I’m mourning the end of blueberry season myself. Fortunately, I’ve developed an affection for this year’s peaches, which are LOVELY.
Liz C. says
I think you should also have a small restaurant at your vineyard so you can serve delectible delights like this! Maybe it could even be part of the Tasting Room. Just a thought. You are such an amazing cook.
dawn says
I love that bars are showing up everywhere. That bottom crust cath is to die for. gorgeous.
Katie says
I wish I could jump through the screen and eat the whole pan of these they look so good.
Glamorous Life of a Housewife says
I AM MAKING THOSE SOOO SOON! My mouth is watering. Literally. YUM!
Indigo says
I’m fairly certain that these bars will make my life complete, and for that, I salute you.
Melissa says
I have a new addiction… Please feed me!
Andi Sexton (rrlscrapgal) says
Cathy darling…
I just got done surfing all your recipes and I need a good brownie recipe!
Do you have one tucked away somewhere?
My husband hates boxed brownie mix! Well, we all do. They are only good the first day… we need a rip roaring family pleasure.
Help!
jennyonthespot says
NP, those look absolutely delightful. I have pounds of blueberries in my freezer (I hoarded them when they were on sale this summer)… I can’t wait to try this out!
Kristen says
That looks seriously good! Seriously. Yum!
Jude says
If only my kitchen was as orderly as yours.. I might actually be able to.. see the floor or something. Looks delicious.. Not too late for blueberries for sure.
Rosa says
Fantastic! Those bars look terribly good! Thanks for sharing!

Harmony says
Man I knew I was missing out…when I got behind on my blog reading (especially yours) but…wow..I guess I didn’t realize the extent of it..Thank goodness you are here! Great recipe…can’t wait to try it. And I shall never fall behind again!!!
dlyn says
I am betting these will work just fine and dandy with the frozen berries I have from my mother in law’s bushes this summer. Mmmmmmmmmm!
Cecil says
I am cooking solo these few nights – with one or two friends dropping in. But I am really thinking about making this and just eat it all myself!!!
chefectomy says
After the horse poo post I was steering clear here for a bit…and then you posted this. So right on. And that pic of the berries with the dough (prior to baking)..nailed it.
Kim says
Cathy-these look so good and I am always up for blueberry anything. But I will have to take a second job to buy these at the price they are going for! As always tempting food.
Familia says
oh, wow, we ate every last one…they were so good.
Kevin says
THose look so good! I really like that layer of cream in them.
barbara says
OH MY GOD. Who do I need to sleep with to get some of that.
Maryann says
Good Lord Woman….i was looking for a site to curb my appetite for blueberries and now look what you have done …… can’t fight the addiction now and I had to make them, they were amazing!
Lauren says
I had a pint of blueberries, sorted through a ton of recipes, and picked this one to try. I tastes very good. I had to substitute key limes for the lemon, and next time, if I choose to use key limes again, I will use less zest. I might also try to somehow increase the amount of lemon (lime) mix, it seemed pretty scant compared to the crust. I would also use more than the pint of blueberries I had. I didn’t measure them, but I think it was less than the 2 1/2 C. called for. It is already good, considering I tweaked the recipe to use limes and probably less blueberries. The recipe the way it is supposed to be is probably perfect (except for maybe a bit more of the lemon stuff.
Debbie says
Made these for Mother’s Day and they were a hit! Half of the pan devoured…..by 6 of us! Whoops! So tasty, thanks for the great recipe. đŸ™‚
Lauren Kelly says
I’ve made this several times and I swear it gets better all the time. I have frozen blueberries in the freezer and I’m so excited to make these again!
wilhlemina says
These bars are incredible! The whole pan was gone in less than a day. SO, SO good!
Toni says
This is really fantastic! I love the combination of flavors!
Suzy says
The blueberries tasted so good with the lemon filling! Delicious!
Terry says
Fantastic recipe…but be generous with the berries…my berries were large and didn’t cover bottom of pan so I added extra cup of them and it was perfect.
