Cook techniques
Whisking
Whisk together dry ingredients in a bowl to ensure they are evenly combined and to incorporate air for a lighter texture in the crust.
Mixing
Combine the melted butter with the dry mixture until crumbly. This creates a texture suitable for pressing into the pan for the crust.
Pressing
Firmly press the mixture into the bottom of the pan to form a sturdy crust that will hold the berry filling.
Layering
Layer the fruit carefully and sprinkle cornstarch evenly to help thicken the juices during baking, ensuring a nice consistency.
Baking
Bake until the topping is golden brown and the filling is bubbling, which ensures the bars cook evenly and the flavors meld.
Cooling
Allow the bars to cool completely in the pan before cutting, as this helps them set and makes them easier to slice.
Glazing
Mix powdered sugar with heavy cream to create a glaze. Adjust the cream gradually to achieve the desired consistency for drizzling.
