This Brown Sugar Caramel Blackberry Peach Crisp is one I’ll be making all summer long. Sweet peaches and blackberries bake down into the most delicious brown sugar caramel sauce, then get topped with double the buttery oatmeal crumble. The fruit becomes even sweeter, the topping bakes up crisp and golden, and every spoonful is better with melting vanilla ice cream. It’s the dessert everyone always goes back for seconds.

Summer desserts have always been some of my favorites. It’s funny because growing up, we were all about chocolate, even in the middle of summer. Honestly, I still can’t pass up a good chocolate dessert, especially ice cream. But there’s something about a warm fruit crisp on a late summer afternoon, when the sun is still high but the evenings are beginning to cool, that feels so comforting.
Fruit crisps were never reserved for special occasions in our house. If there were peaches on the counter or berries that needed using, I was almost always making a crisp.
If you’ve been following along for a while, you might remember my Blackberry Kahlúa Crisp with Double the Crumble from way back in 2014. Believe it or not, I still make that recipe all the time. The crumble is one of my all-time favorites, and the Kahlúa gives the berries the most unexpected richness.

For years, I’ve wanted to create a version with peaches and blackberries. Instead of using Kahlúa, I leaned into brown sugar and butter, letting them melt together with the fruit as it bakes to create a rich, self-saucing caramel that bubbles up around every peach and blackberry. Honestly, it’s one of the very best parts of this recipe.
And of course, I kept the double crumble. I wouldn’t have it any other way. If you’ve made any of my crisps before, you already know I believe there’s no such thing as too much buttery oatmeal topping. It bakes up perfectly crisp and golden while soaking up just enough of that caramel sauce underneath.
Serve it warm with big scoops of vanilla bean ice cream and plenty of those buttery brown sugar caramel juices spooned over top. It’s summer dessert at its very best.
