Before we round the corner into September (!!), I have one last ice cream recipe for you. Churning frozen treats has definitely been my summer 2019 obsession — I’ve been making frozen yogurt, sorbet, sherbet, eggless ice creams, and custard ice creams as fast as we can consume or share each batch. It’s just so addicting (and delicious)!

I’ve especially enjoyed trying to incorporate various seasonal fruits into ice cream. While either sorbet or an eggless (“Philadelphia”) ice cream base has been my modus operandi when incorporating fruit — I find the lack of eggs helps the fruit flavor shine through better — this time I was going for a peaches and cream vibe and wanted a bit of extra richness. I used the same buttermilk custard base from the toast and jam ice cream, but added in a honey-sweetened roasted peach puree. Swirls of peach jam amp up the “peachiness” while sprinkles of crisp oat streusel add texture and nuttiness. It’s like eating a peach crisp a la mode!

A few notes:

• This makes a fairly large batch of ice cream — probably the largest amount my home ice cream maker can handle. If you have a smaller machine you will want to churn in two batches (or reduce the recipe by 25-30%).
• The oat streusel recipe is adapted from Jeni’s Splendid Ice Creams at Home and makes way more than you need for this batch of ice cream. But! It freezes beautifully and I have absolutely loved having a big batch on hand to layer in other ice creams / sprinkle on sundaes / snack on. So I definitely recommend just making the full batch and patting yourself on the back later.
• My favorite containers for storing ice cream are these Cambro 1-quart Poly Rounds. They don’t take up a lot of room in the freezer and they’re the perfect size for a typical home batch. But you can use a loaf pan, empty yogurt container, or similarly-sized freezer-safe vessel. Whatever container you choose, I recommend sticking it in the freezer while you are churning your ice cream to help minimize melting!

Peach Crisp Ice Cream

Makes a generous 1 quart | Inspired by Salt & Straw and Jeni’s Splendid Ice Creams at Home

Ingredients:

For the buttermilk custard base:

• 1/2 c + 2 Tbsp / 125g granulated sugar
• 2 Tbsp dry milk powder
• 1/4 tsp xanthan gum
• 4 large egg yolks
• 2 Tbsp / 40g light corn syrup
• 1 1/2 c heavy cream
• 1 1/2 c buttermilk
• 1/4 tsp kosher salt

For the roasted peach puree:

• 12 oz ripe peaches, pitted and chopped
• 80g (1/4 c) honey

For the crisp oat streusel:

• 227g cold, unsalted butter, cut into 1/2″ cubes
• 188g AP flour (swap in whole grain if you’d like)
• Pinch of ground cinnamon
• 150g light brown sugar
• 1 tsp kosher salt
• 135g old-fashioned rolled oats

To finish:

• ~1/2 c peach jam, homemade or store-bought

Method:

1. Make the buttermilk custard base: Combine the cream and buttermilk in a large measuring cup.
2. Combine 100g (1/2 c) of sugar, dry milk powder, and xanthan gum in a small bowl and whisk well. In a large bowl, combine the egg yolks and remaining 25g (2 T) sugar and whisk until the yolks are lighter in color, about 1 minute.
3. In a medium pot, combine the corn syrup and half (1 1/2 c) of the buttermilk/cream mixture. Add the sugar mixture and immediately whisk vigorously until smooth. Set the pot over medium heat and cook stirring often and adjusting the heat if necessary to prevent a simmer, until the sugar has fully dissolved (about 3 minutes). Remove the pot from the heat. Start whisking the yolk mixture and continue to whisk constantly while slowly drizzling the hot liquid into the yolks.
4. Scrape the entire mixture back into the pot and cook over medium-low heat, whisking constantly, until the custard is thick enough to coat the back of a spoon (it should register ~170F on a digital thermometer). Strain into a heatproof and airtight container and whisk in the remaining buttermilk/cream mixture. Cover and refrigerate until well-chilled, at least 6 hours and up to 1 week.
5. Make the peach puree: Preheat oven to 350F. Spread the chopped peaches in a single layer on a quarter-sheet baking pan lined with parchment paper. Drizzle with honey.
6. Bake peaches for about 30-40 minutes, stirring every 10-15 minutes, until the released juices have thickened. (The peaches shouldn’t be browned at all.) Remove from oven and allow to cool to room temperature. When cool, scrape the peaches and all the syrupy juices into a food processor or blender. Blend until smooth. Transfer to an airtight container and refrigerate until cold.
7. Make the crisp oat streusel: Preheat oven to 350F. Line a large baking sheet with parchment paper or a silicone mat.
8. In a large bowl, whisk together the all dry ingredients except the oats. Add the cubed, chilled butter and rub it into the dry mixture with your fingertips until the mixture resembles coarse sand. Add the oats and stir to combine well. Spread the mixture in a single layer onto the prepared baking sheet, aiming for clumps about 1/4″-1/2″ in size.
9. Bake for 30-35 minutes, stirring occasionally, until toasted and browned. Cool completely on a wire rack, then freeze in a ziplock bag or airtight container until ready to use.
10. Churn the ice cream: Whisk 1/4 tsp kosher salt and chilled peach puree into the chilled buttermilk base. Churn according to the instructions for your machine, until the mixture has the texture of soft serve. Transfer to a freezer-friendly container, alternating with dollops of peach jam and generous sprinklings of oat streusel. Cover with parchment paper, pressing it to the surface of the ice cream so it adheres, then cover with a lid. Freeze until firm, at least 6 hours. Ice cream will keep for up to 3 months.
