Say hello to your new favorite summer dessert! Freshly milled strawberry crumble bars are bright, sweet, and perfectly balanced between crunchy and chewy.
In a small saucepan, combine the frozen strawberries, sugar, lemon juice, lemon zest, and cornstarch. Heat over medium heat, stirring frequently. As the strawberries soften, use a fork to gently mash them. Continue cooking for 5–10 minutes, until the mixture thickens slightly and reaches a thin, syrup-like consistency.
Preheat the oven to 375°F. Line a 9×13 baking dish with parchment paper**.
In a large bowl, combine the brown sugar, granulated sugar, flour, baking powder, and salt.
Add the cold butter and work it into the dry ingredients using a fork until the mixture is crumbly.
Add the egg and mix until the dough starts to come together. It should still be crumbly but hold when pressed. If it's still too dry, add 1-2 tablespoons of milk.
Press about half of the mixture firmly into the bottom of the prepared baking dish to form the crust. Set the remaining crumble aside.
Pour the strawberry mixture over the crust and spread it out evenly.
Sprinkle the remaining crumble mixture evenly over the top.
Bake for 35-40 minutes, or until the top is lightly golden and the filling is bubbling.
Allow the bars to cool completely before slicing.
Notes
*The dough should feel slightly crumbly but hold together when pressed. If it feels too dry, add 1–2 teaspoons of cold water or milk.
Conversely, avoid adding too much milk to the crumble mixture. You want it to be pretty dry, but still hold together if you squeeze it between your hands.
**Rather than lining the pan with parchment paper, you can grease the baking dish with coconut oil.
Soft white wheat works best here and gives you that tender, crumbly texture.
Allow the bars to cool completely before slicing! They firm up as they sit — if you try to cut them while still warm, they will be too crumbly and will fall apart.
Serve these bars by themselves or top them with a scoop of vanilla ice cream!
