Pumpkin Brown Sugar Crunch Ice Cream

Pumpkin brown sugar crunch ice cream is made with a buttermilk pumpkin custard, dark brown sugar, and warm spices. I churn homemade brown sugar pecan streusel into the ice cream, so it has a buttery texture and lots of pecans mixed in, even after the streusel softens.

Pumpkin Brown Sugar Crunch Ice Cream with Buttermilk and Pecan Streusel

I didn’t want pumpkin ice cream that tasted like frozen pumpkin pie filling, which is why I use buttermilk with the milk and cream. It adds acidity to the custard, which is what keeps the dark brown sugar from tasting so sweet. Without the acidity, the sweetness overwhelms the pumpkin and spices, and it’s not the same contrast with the molasses flavor of the dark brown sugar. It’s more of a food science decision, than a “this just tastes better” option.

The brown sugar pecan streusel was always going into the ice cream, not something I planned to sprinkle over the top. I bake it separately, break it apart, and add it during churning so the pecans and buttery streusel are mixed in. Some of the crunch softens as the ice cream sits in the freezer, and I really do like it that way.

Making custard-based ice cream does take more effort than stirring together a few ingredients and putting them in the freezer. It’s cooking the custard, chilling it, churning the ice cream, and waiting for it to firm up. But I don’t mind spending that time on ice cream when there’s homemade pecan streusel involved. I’d happily serve this on Thanksgiving right next to the pumpkin pie, but it’s also pretty devastating on a sugar or waffle cone. Fair warning.

The Decisions Behind This Recipe

• Pumpkin, cream, and dark brown sugar get pretty rich together, so I put buttermilk in the custard. I don’t want sour ice cream, just enough tang that it’s not cloying. What’s important when you’re eating it is that you can taste the pumpkin, the spices, and the brown sugar without the sweetness being the focus. I think I got there.
• I wasn’t interested in using light brown sugar when dark brown sugar has way more molasses flavor. It’s good with the pumpkin and the streusel.
• As much as I love cooking from scratch, I’m not roasting a pumpkin to make ice cream. Canned pumpkin purée is consistent, tastes good, and saves time. Use pure pumpkin purée, not pumpkin pie filling with sugar and spices already added.
• Five egg yolks aren’t unusual in a custard-based ice cream and pumpkin purée changes the situation somewhat. There’s extra water and starch in the mix. A good custard is how I still get creamy, scoopable ice cream, not something that feels like it belongs in a square baking dish.
• The pecan streusel is for the inside of the ice cream. You could sprinkle extra on top, but it was made to be inside. Baking it first gives the butter, brown sugar, and pecans time in the oven to develop their flavor, and adding it toward the end of churning keeps the machine from breaking it apart too much. Some of the crunch will soften in the freezer, which doesn’t bother me at all. I still get the pecans and the buttery streusel mixed into the custard. It’s one of the best parts of this ice cream.
• I save the turbinado sugar for serving because I like the coarse sugar crunch when I’m eating the ice cream. And it looks good. There’s already brown sugar in the custard and streusel, and mixing turbinado into either doesn’t give the same result as sprinkling it over a scoop.

Ingredients

• Whole milk, heavy cream, and buttermilk – All three go into the custard, but the buttermilk is what keeps the pumpkin ice cream from tasting like a frozen bowl of heavy cream.
• Pumpkin purée – Straight from the can. Make sure you’re buying pure pumpkin and not pumpkin pie filling.
• Dark brown sugar – I want that stronger molasses flavor in both the ice cream and the streusel. If you’re out, make a batch of my homemade brown sugar.
• Granulated sugar – Homemade ice cream needs enough sugar to stay scoopable in the freezer, so this isn’t the place to start cutting it back because the custard tastes sweet before it’s frozen.
• Pumpkin pie spice – I use the prepared blend instead of measuring out several individual spices.
• Egg yolks – You’ll need five for the custard. Save the whites for my angel food cupcakes instead of letting them sit in the refrigerator.
• All-purpose flour – This goes into the brown sugar pecan streusel, where it helps the butter and brown sugar bake into something that can be broken apart and mixed into the ice cream.
• Butter – I use unsalted butter for the streusel.
• Pecans – Chop them, but leave some larger sized ones. You want the pecans noticeable when eating the ice cream.
• Cinnamon – There’s pumpkin pie spice in the custard, but the streusel also needs it.
• Turbinado sugar – Optional for serving, but I like the coarse sugar crunch over the ice cream. And it looks good.

How to Make Pumpkin Brown Sugar Crunch Ice Cream

• Step One (make the pumpkin custard base)
  In a medium saucepan, whisk together the whole milk, heavy cream, buttermilk, pumpkin purée, dark brown sugar, granulated sugar, and pumpkin pie spice. Warm the mixture over low heat, stirring now and then, until you see small bubbles around the sides of the pan. Don’t let it boil. I want it hot enough to warm the egg yolks without cooking them the second they hit the pan.
• Step Two (temper the egg yolks and cook the custard)
  Whisk the egg yolks in a separate bowl, then slowly drizzle in about ¼ cup of the warm pumpkin mixture while whisking the whole time. Do that again with another ¼ cup, then pour the warmed yolks back into the saucepan. Keep the heat low and stir constantly, scraping the bottom of the pan as you go. Cook the custard until it coats the back of a spoon and reaches 175–180°F. I use a thermometer because there’s a very clear line between cooked custard and scrambled eggs, and I prefer not to find it by accident.
• Step Three (chill the custard)
  Pour the custard through a fine-mesh strainer into a bowl. I strain it even when everything looks fine because it catches any bits of cooked egg before they get into the ice cream. Set the bowl in an ice bath until it has cooled down, then cover and refrigerate it for at least 8 hours or overnight. Don’t rush this part. Warm custard takes forever in the ice cream maker, and nobody needs that kind of afternoon.
• Step Four (make the brown sugar pecan streusel)
  Preheat the oven to 350°F. Mix the dark brown sugar, flour, and cinnamon, then cut in the cold butter until the mixture is crumbly. Stir in the chopped pecans and press everything into a greased 8 × 8-inch or 9 × 9-inch baking dish. Bake for 12–15 minutes, until it’s golden and smells toasted, then let it cool completely before breaking it apart. Leave some larger pieces in there. The ice cream maker will take care of enough of the rest.
• Step Five (churn the ice cream)
  Pour the cold pumpkin custard into your ice cream maker and churn it according to the manufacturer’s instructions. When it looks like soft serve and is nearly finished, add the cooled pecan streusel. Let the machine run long enough to mix it through. I want buttery pecan streusel in the ice cream, not a bunch of crumbs floating around.
• Step Six (freeze and serve)
  Transfer the ice cream to a freezer-safe container, cover it tightly, and freeze it for at least 6 hours or overnight. It will still be soft when it comes out of the ice cream maker, so it needs that time before it’s ready to scoop. Sprinkle turbinado sugar over the top before serving if you want the extra crunch. I like it with the softer streusel that’s been sitting in the custard.

Recipe Tips

• If you have a metal loaf pan, put it in the freezer before you churn the ice cream. I like transferring the freshly churned ice cream into an already cold container because it helps keep the ice cream from warming up while I’m transferring it. It’s not required, but it’s an easy thing to do while the ice cream maker is running.
• Check the capacity of your ice cream maker before pouring in the custard. The mixture needs room to expand as it churns, and some machines have smaller capacities than others. If your machine can’t accommodate everything, divide the custard into batches and keep the second batch refrigerated until you’re ready for it.

Storage

• Store the ice cream in a freezer-safe container with a tight-fitting lid. Press a piece of parchment directly against the surface before sealing to help limit ice crystals. For the best texture and flavor, I recommend eating it within two weeks. You can also make it a few days ahead of an event without worrying about dessert.
• If the ice cream is too firm to scoop straight from the freezer, leave it at room temperature for 5–10 minutes. Homemade custard ice cream can freeze pretty hard, and a short wait makes scooping much easier.
• If you’re serving this for Thanksgiving, you can scoop individual portions ahead of time and freeze them on a parchment-lined baking sheet until firm. Transfer the scoops to a covered freezer-safe container until you’re ready to serve. It’s a lot easier than standing over a container of ice cream trying to scoop dessert for everyone while the pie is getting cold.

FAQs

• Can I use light brown sugar instead of dark brown sugar?
  You can, but the ice cream won’t have as much molasses flavor. Light brown sugar is good in other pumpkin forward desserts like my pumpkin brown sugar muffins, but for this ice cream, I like dark brown sugar.
• Can I make pumpkin brown sugar crunch ice cream without an ice cream maker?
  This recipe needs an ice cream maker. Churning incorporates air and helps keep large ice crystals from forming as the custard freezes. Without it, you’d end up with something much denser and icier than ice cream should be.
• Can I make the brown sugar pecan streusel ahead of time?
  Yes. You can bake the streusel a day or two ahead, let it cool completely, and store it in an airtight container at room temperature. Keep it separate from the custard until you’re ready to churn the ice cream. There’s no advantage to putting it into the custard early and letting it soften before it even reaches the ice cream maker.

From My Kitchen Notes

Small observations from the margins.

• I don’t need things to stay frozen to keep them from changing.
• I can let something soften without calling it ruined.
• Sweetness is better when it knows when to stop.
• I don’t have to keep things separate for them to be mine.
• I can wait until something cools down before I decide what it needs.
• I know when to save texture for the end.
• I can let something sit with me without expecting it to stay the same.
