Blueberry Walnut Crisp

Blueberry Walnut Crisp

Quicker to make than a pie or a cake, crisps bring summer home to your kitchen in less than 15 minutes of assembly. Making a blueberry crisp allows you to celebrate summer where you belong–outside! Adding our Organic Heirloom Blueberry Powder to the topping makes for an extra colorful and flavorful crisp!

Yield: 8-10 servings | Prep: 15 minutes | Bake: 45 minutes 


2 pints fresh blueberries (or 4 cups frozen)

Zest of 1 lemon

2 tablespoons cornstarch

¼ teaspoon kosher salt

½ cup sugar

2 tablespoons lemon juice 


¾ cup flour (can use any GF flour)

¾ cup walnuts, coarsely chopped

¾ cup brown sugar

¾ cup oats

¾ cup sugar

1 teaspoon kosher salt

2-4 tablespoons Organic Heirloom Blueberry Powder

6 tablespoons unsalted butter, cubed


Heat oven to 375°F. Butter a 9” x 9” baking dish.

In a large bowl, toss the blueberries, zest, cornstarch, salt, and sugar. Combine with the lemon juice. Pour into the prepared baking dish.

For the topping, mix all of the dry ingredients (everything but the butter). Using your fingers, crumble the butter into the mixture, pinching to combine. Spread the crumble on top of the blueberries.

Bake 45 minutes or until browned and the edges are bubbly. Serve warm or at room temperature with whipped cream or ice cream.


The sky is the limit on various baking spices and flavors that can complement the crumble topping.

Here are a few additional flavor ideas:

1 teaspoon of dried ginger + zest of one orange 

½ teaspoon of cardamom

1 teaspoon cinnamon

½ teaspoon cardamom + ½ teaspoon cinnamon + ¼ teaspoon allspice + ¼ teaspoon nutmeg

Substitute hazelnuts or almonds for the walnuts
