This sweet and buttery blueberry crisp comes together in under an hour and delivers the taste of peak summer in every bite. Juicy berries bubble beneath a golden oat topping that is equal parts crisp and tender, making it just right for sharing at outdoor gatherings or casual family meals.

I first made this blueberry crisp after a day of berry picking and it disappeared before it even cooled. Now when blueberries are in season my family asks for it every week.

Ingredients

  • Blueberries: Fresh or frozen full of antioxidants and natural sweetness I look for plump berries with no signs of shriveling
  • Sweetener: Any type works like regular sugar coconut sugar or even maple syrup Adjust to your taste
  • Cornstarch: Optional but helps thicken the berry juices Choose a non clumping brand for best texture
  • Flour: Use white spelt or oat flour for a tender crumb Make sure it is fresh with no off odor
  • Rolled or quick oats: Brings the classic crisp texture Opt for rolled oats if you want more chew
  • Sugar: Adds sweetness Choose unrefined for a hint of molasses flavor
  • Cinnamon: Gives a gentle warmth Use high quality cinnamon for best aroma
  • Butter or coconut oil: Makes the crumble rich and crisp Cold butter works best for cutting into the topping

Step-by-Step Instructions

Prepare the Oven and Pan:
Set the oven to 375 F and grease your baking dish well to prevent sticking
Make the Blueberry Base:
If using frozen berries let them thaw fully Spread the blueberries in the pan and scatter over your sweetener and cornstarch if you like a thicker filling Toss gently so the berries are evenly coated
Mix the Crisp Topping:
In a large bowl add the flour oats sugar and cinnamon Stir well ensuring there are no lumps
Add Butter for Crumble Texture:
Cut cold butter into small cubes and add to the bowl Use a fork or pastry cutter to work the butter into the dry mix until it forms pea sized crumbs If you choose coconut oil mix until just incorporated
Top and Bake:
Sprinkle the oat topping evenly over the berries Do not pack it down Bake in the center of the oven for 25 to 30 minutes The topping should look golden and the berries will be bubbling at the edges
Cool and Serve:
Let the crisp sit at room temperature at least 15 minutes so the juices thicken Serve with a scoop of vanilla ice cream or whipped cream for a classic touch

I always double the oats and butter for extra crunch because that is the part everyone fights over. One summer memory I cherish is making this with my grandmother after picking blueberries from her backyard bushes and eating it still warm on the porch.

Storage Tips

This blueberry crisp stays fresh up to four days when covered and refrigerated. I often freeze individual portions wrapped tightly in foil for a quick treat. To reheat either microwave briefly or warm in a medium oven until bubbly.

Ingredient Substitutions

You can swap the blueberries for any mixed berry blend raspberries or even diced apples for a fall twist. For a gluten free version use almond or certified gluten free oat flour. Coconut oil or plant based butters work just as well as dairy butter.

Serving Suggestions

Blueberry crisp tastes wonderful on its own but takes dessert up a notch with a scoop of vanilla ice cream or a dollop of Greek yogurt. For brunch layer it over pancakes or mix it with creamy yogurt and granola for a parfait.

Steps to Follow

Step 01

Preheat oven to 375°F. Grease an 8x8 inch pan or double the recipe for a 9x13 inch pan.
