Blueberry crumble with vanilla ice cream.

Blueberry Skillet Crisp

08/31/2025 | Bonia Bakery |

There’s something about summer that makes me crave the simplest desserts—the kind that don’t take much fuss, just a handful of good ingredients and a little oven magic. For me, that’s where this blueberry skillet crisp comes in.

Growing up, fruit crisps were one of the first desserts I learned how to make. My mom always kept bags of frozen fruit tucked away in the freezer, so whenever we wanted something sweet, we’d throw together a quick crisp. It felt like the most effortless treat, but when it came bubbling out of the oven, it tasted like the best kind of comfort food.

This blueberry version is one of my favorites. Fresh (or frozen) blueberries bake down into a jammy, bubbling filling that’s sweet but still a little tart. On top, you get this golden, crunchy cinnamon-oat crumble that adds just the right amount of texture. And of course, you can’t forget the scoop of vanilla ice cream on top—it melts into the warm crisp and creates the most dreamy bite.

What I love about this recipe is how forgiving it is. You don’t need to fuss with a pie crust or wait hours for anything to cool—it’s rustic, cozy, and perfect for sharing right out of the skillet. If you’re anything like me, you’ll want to keep this recipe close by for those nights when you need a quick dessert that feels special but doesn’t require much effort.

Ingredients

Blueberry filling:

  • 2 1/2 cups fresh or frozen blueberries
  • 2–3 tbsp granulated sugar
  • 2 tbsp all-purpose flour
  • 1 tsp lemon juice
  • Pinch of salt

Crisp topping:

  • 1/4 cup all-purpose flour
  • 1/4 cup cinnamon oats
  • 3–4 tbsp granulated sugar
  • 3–4 tbsp light brown sugar
  • 1/4 tsp salt
  • 1/4 cup unsalted butter, melted
  • Vanilla ice cream, for serving

Directions

  1. Preheat your oven to 375°F. Lightly grease the bottom of a cast-iron skillet with nonstick spray or oil.
  2. In a mixing bowl, toss together the blueberries, sugar, flour, lemon juice, and salt. Transfer the mixture into the prepared skillet. (If you’re using frozen berries, the flour may seem excessive at first, but trust me—it bakes up just right.)
  3. In the same bowl, stir together flour, oats, both sugars, and salt. Pour in the melted butter and mix until the topping becomes crumbly. Sprinkle this evenly over the blueberries.
  4. Cover the skillet loosely with foil and bake for 15 minutes. Remove the foil and continue baking, uncovered, until the topping is golden and the berries are bubbling around the edges—about 25–30 minutes more.
  5. Allow the crisp to cool slightly before serving warm. Add scoops of vanilla ice cream on top and enjoy every melty, cozy bite.
