Lemon Cheesecake Bars with Lemon Curd and White Chocolate

Thick lemon cheesecake bars with white chocolate in the base and lemon curd layered in, not on top. The lemon is worked into the batter and added again so it doesn’t end up sitting in one place or fading out once it bakes.

Lemon Cheesecake Bars and What Happened Overnight

I didn’t want these to be the usual baked lemon cheesecake bars, so I added white chocolate to the base and worked lemon curd in more than once. I also added something so the lemon doesn’t fade out once they’re in the oven. The bars set up once chilled, with a crust that doesn’t fall apart when you cut into them. These tie back to a very specific memory that still makes me laugh when I think about it.

Years ago, my oldest was headed to Stanford for a few weeks of an intensive summer speech and debate camp. I packed the car like I was moving him in permanently, got him settled, and then stuck to a plan I had already mapped out, which was to act like a tourist in my previous home state and revisit all my favorite places before picking him up again. Mendocino first, the Anderson Valley, the Sonoma Coast, back through Davis to see friends, and San Francisco at the end, staying right in the Wharf.

The SF hotel was really nice. It wasn’t new, but was a very established, highly rated, well-known hotel. The interior was beautiful, curated and welcoming with a very relaxing atmosphere.

So when I woke up a few days into it and found a printed note under the door saying the hotel had changed overnight, I stood there looking at it.

Not “is changing.” But changed.

There was a new name, new management, and they needed my credit card because they didn’t have it anymore.

I remember thinking, how do you not have it. Was there a hostile takeover? What happened?

After getting ready, we walked out into the lobby, and just stopped.

It was completely different. COMPLETELY. This was not some sort of refresh or an update. It was totally different. There was new paint, new light fixtures, a whole new front desk area, white walls were now dark blue, new lobby furniture, restaurant completely different. It was like one of those HGTV remodels except they somehow did this in 10–12 hours in the Wharf, one of the most complicated, busy areas of San Francisco, where semitrucks would have had to bring in all this furniture. It was that overhauled.

It was obvious everyone standing around looking at each other were as dumfounded as I was. Breakfast there had been the plan, but it was so chaotic that morning it wasn’t worth it.

Ended up at a massive In-N-Out Burger just down the way, before hopping on a boat and heading to Alcatraz with my youngest. We were gone all day. Had a blast. Stayed way longer than expected. Took lots of hilarious photos in the jail cells. There was even an old inmate there talking about the book he just wrote. Of course I bought it. Had him sign it, and by the time we came back I wasn’t even thinking about the hotel changeover anymore.

Until we opened the door to our room.

“Oops, this isn’t our room.” Except it was.

The entire bedroom had been wallpapered, not just a strip or a punch wall, the whole room. There were new headboards, lamps, nightstands and new bedding. In the living room area, new couches and chairs, and new patio furniture on the balcony. There was not one single thing that remained the same, from the shampoo brands to robes in the closet. And interestingly, all of our stuff was sitting exactly where we had left it originally, as if someone had taken a picture and put it back exactly the same. That was odd in its own way.

I remember saying, how long were we gone. My youngest asked if we were being punked.

And then, what if we were only going to be out for an hour. Would there have been a sign that said, come back later, we’re wallpapering?

Because that part doesn’t work.

I distinctly remember the note on the coffee table, “Welcome Back to Your New Room, with about eighteen exclamation points after those words, (like SURPRISE!!), next to a tray of lemon bars, with white chocolate on top and the new hotel name stamped into it.

I was eating a really good lemon bar in a room that didn’t exist that morning. I still laugh about it, because I don’t really know how they pulled it off.

Now anything lemon in bar form sends me right back to that room. I don’t really think about the hotel or the lobby, but that moment sitting with one of those, trying to make sense of what I just walked into.

Those weren’t cheesecake bars, but that combination of lemon and white chocolate has rattled around in my brain ever since. So when I started working on these lemon cheesecake bars, I decided to add white chocolate and that lemon curd was happening too. I didn’t want the usual, plain kind that was soft in the middle or with lemon flavor that only sits on top.

The lemon needed to be there more than once,  so I folded it into the batter and swirled it through the surface. And I put the white chocolate right into the filling so it didn’t turn into a straight lemon dessert.

And because of that, they cut into perfectly shaped bars, not soft squares you have to scoop around, but bars that lift out of the pan and fit into your hand.

What I Did Differently

• I made sure this isn’t a basic lemon cheesecake bar.
• Most lemon cheesecake bars are cream cheese, sugar, and lemon, maybe a swirl on top if you’re lucky. I went further, starting with the base.
• The white chocolate is melted with cream and added directly into the cheesecake batter, which changes how the lemon comes through, by not sitting separate or dropping off after a few bites. This was important to me.
• Not wanting the lemon curd to be just a topping, I folded it into the batter and then added it again on top before baking. So, you’re getting that lemon-y flavor layered all the way through instead of only on the surface. It’s definitly a POW moment.
• A small amount of flour and the extra egg yolks keep the center from going too soft, so once they’re chilled, you can lift a piece straight out of the pan and it stays together. That’s the difference between something that looks good in the pan and something that stays together when you serve it.
• Keep the mixing low speed the whole time. This is key once the eggs go in, and how I kept the batter from getting too light or uneven, and remaining consistent across the whole batch.
• And then there’s the lemon emulsion, which is one of those small additions that makes a bigger difference than it sounds like it should. I highly recommend grabbing a bottle. This is why bakery bars taste so much more lemon-y. It keeps the lemon flavor from fading once the bars bake, so what you taste going in is still there when they come out of the oven.

Ingredients

• Graham crackers – Pulse them fine so the crust presses in tight and doesn’t break apart later. If they’re too coarse, you’ll notice it when you try to lift a piece out.
• Granulated sugar – Works in both the crust and the filling. It sweetens, but more importantly it keeps everything from tasting plain once it’s baked and chilled.
• Butter – This is what sets the crust once it bakes. If it’s off here, the base won’t stay together once the filling goes on.
• White chocolate chips – Melted with a little cream and added into the batter. This changes how the lemon ultimately tastes so it doesn’t feel separate from everything else. Use good quality chocolate chips, otherwise they’re too waxy.
• Heavy cream – Used to melt the white chocolate and again for the topping. It keeps everything from getting too thick or too sweet once it’s all together.
• Cream cheese – Needs to be full-fat and fully at room temperature so it blends smoothly without forcing you to overmix.
• Flour – A small amount, but it makes a difference. This keeps the center from going too soft once everything sets, helping the bars stay firm once fully chilled.
• Eggs + extra yolks – The yolks keep the texture rich without weighing it down.
• Lemon emulsion or extract – This is the lemon flavor that stays after baking. Juice and zest will fade, this won’t.
• Lemon curd – Used in the batter, swirled on top, and added again to the whipped cream so the lemon goes through the whole bar instead of just on top.
• Confectioners’ sugar – For the whipped cream so it blends smoothly without any graininess.

• Step One (prep the pan and crust)
  Preheat the oven to 350°F and line a 9×13-inch pan with parchment so you can easily lift everything out later. Pulse the graham crackers down until they’re fine, mix with sugar and melted butter, then press the crumbs firmly into the pan. Bake it for about 10 minutes just to set it, then drop the oven to 325°F.
• Step Two (melt the white chocolate)
  Warm the white chocolate with the cream in short bursts, stirring until it’s smooth. Let it sit for a minute so it’s not hot when it goes in. If it’s too warm, it’ll throw everything off.
• Step Three (build the cheesecake base)
  Mix the cream cheese, sugar, and flour on low until it’s smooth. Keep it low. There’s no reason to hurry through this part. Add the melted white chocolate and lemon emulsion and mix until it comes together.
• Step Four (eggs go in last, slowly)
  Add the eggs and extra yolks one at a time, until they disappear into the batter. This is not the place to speed things up. If you overdo it here, the texture won’t be the same.
• Step Five (layer in the lemon curd)
  Fold most of the lemon curd into the batter so it mixes into everything instead of sitting in one spot. Pour it into the crust, then spoon the rest over the top and swirl it lightly. You want to still see it. If it disappears, you went too far.
• Step Six (bake until it’s there)
  Bake at 325°F for about 42–45 minutes. The edges will look set and the center should still move slightly when you jiggle the pan. If you check the temperature, you’re around 150–155°F in the middle.
• Step Seven (cool, then chill)
  Let it cool at room temperature first, then refrigerate until it’s fully chilled. These are baked lemon cheesecake bars, and this is where they fully set. If you cut it too early, you already know how that’s going to go.
• Step Eight (finish and slice)
  Whip the cream with confectioners’ sugar and a little lemon curd until it’s thick enough to sit on top. Lift the bars out with the parchment, slice with a clean knife, wipe between cuts if you feel like it. Add whipped cream and lemon slices or leave them alone. They don’t really need help.

Recipe Tips

• If the crust isn’t packed in tight, it’s going to fall apart later. There’s no saving it. You’ll know the second you try to get a piece out.
• Don’t pour hot white chocolate into the batter and hope for the best. Let the white chocolate cool a bit before adding it. If it goes in too hot, it won’t blend the way you want and it’s hard to fix after that.
• Keep the mixer on low speed the whole time. This is not the place to crank it and get it over with.
• Once the eggs disappear into the batter, you’re done mixing.
• The swirl on top is a quick move. A few passes is all you need. If you keep going, it becomes one with the batter.
• If you wait for the center to look completely set in the oven, you’ve already cooked it too long.
• Let it cool before it goes in the fridge. If the bars go in warm, the texture won’t be the same.
• And if you cut into these too early, they’ll remind you why you shouldn’t have.

Storage

• Once they’re fully chilled, keep them in the fridge.
• If you’re not serving them right away, leave the whipped cream off and add it later so it doesn’t break down.
• Lemon cheesecake bars are best in the first couple days. After that, they’re still fine, but not quite the same.
• You can freeze them. Wrap them well, thaw in the fridge, and they come back without much change.
• Cut them straight from the fridge while they’re cold.

FAQs

• How do I know when these lemon cheesecake bars are done?
  The edges will look set and the center should still move slightly when you jiggle the pan. If you wait until the middle looks completely done, you waited too long.
• Can I use bottled lemon juice instead of emulsion?
  You can, but it’s not close to the same. The flavor won’t come through the same way once it bakes.
• Why are my cheesecake bars too soft?
  It’s usually one of two things. They needed more time in the fridge, or they stayed in the oven too long and didn’t set the way they should have.
• Do I have to use white chocolate?
  No, but then you’re making something else.
• Why did my lemon cheesecake bars crack?
  Usually from overmixing once the eggs go in or leaving them in the oven too long.
• Do I need a water bath for lemon cheesecake bars?
  No. These aren’t that kind of cheesecake. Keep the mixing low and don’t overbake, that’s what’s going to make the difference.
