Ingredients & Prep

Main Ingredients Prep

Mixed berries – Blueberries, raspberries, strawberries, or blackberries all work well. Fresh or frozen berries can be used (do not thaw frozen).
All-purpose flour – Spoon and level for accurate measuring.
Vegan butter – Cold and cubed for the best crumble texture.

Seasonings, Sauces, or Flavor Base

Granulated sugar – Sweetens both the crumble and the filling.
Vanilla extract – Adds warmth and depth to the berry flavor.
Lemon juice – Brightens the filling and balances sweetness.

Pantry Staples

Brown sugar – Adds richness to the crumble.
Cornstarch – Thickens the berry filling so the bars hold their shape.
Salt – Enhances flavor and balances sweetness.
Baking powder – Keeps the base tender, not dense.

Step-by-Step Cooking Instructions

Pre-Cooking Prep

Preheat your oven to 350°F. Line a 9×13-inch baking pan with parchment paper, leaving extra hanging over the sides for easy removal. Lightly grease the parchment.

Cooking Method (Times & Temps)

In a large bowl, whisk together flour, granulated sugar, brown sugar, baking powder, and salt.
Cut in the cold vegan butter using a fork or your fingers until the mixture is crumbly.
Reserve about 1½ cups of the crumble mixture for the topping.
Press the remaining mixture firmly into the prepared pan to form the base.
In a separate bowl, toss berries with cornstarch, lemon juice, and vanilla extract.
Spread the berry mixture evenly over the base.
Sprinkle the reserved crumble evenly over the berries.
Bake for 40–45 minutes, until the top is lightly golden and the filling is bubbling around the edges.

Doneness or Texture Check

The bars are done when the crumble topping is golden and the berry filling looks thick and bubbly. The center should appear set, not wet or loose.

Resting or Final Touches

Let the bars cool completely in the pan for at least 1 hour before slicing. This step is key for clean cuts and a fully set filling.

FAQs

Can I make this ahead of time?
