Ingredients & Prep

Main Ingredients Prep

Strawberries – Fresh strawberries work best. Hull and dice them evenly so they cook at the same rate.
All-purpose flour – Forms the base and crumble topping.
Butter – Cold, cubed butter creates that classic crumbly texture.

Seasonings, Sauces, or Flavor Base

Sugar – Sweetens both the crumble and the strawberry layer.
Lemon juice – Brightens the strawberries and balances sweetness.
Vanilla extract – Adds warmth and depth to the crumble.

Pantry Staples

Rolled oats – Add texture and heartiness to the crumble.
Cornstarch – Thickens the strawberry filling.
Salt – Enhances all the flavors.
Baking powder – Helps the base hold together.

Step-by-Step Cooking Instructions

Pre-Cooking Prep

Preheat oven to 350°F.
Line an 8×8-inch baking pan with parchment paper, leaving overhang for easy removal.
Dice strawberries and set aside.

Proper prep makes assembly quick and clean.

Crumble Base & Topping

In a bowl, mix flour, oats, sugar, baking powder, and salt.
Cut in cold butter until the mixture resembles coarse crumbs.
Stir in vanilla extract.

Press about two-thirds of the mixture firmly into the bottom of the prepared pan.

Strawberry Filling

In another bowl, toss strawberries with sugar, lemon juice, and cornstarch.
Spread the strawberry mixture evenly over the crust.

Baking Method (Times & Temps)

Sprinkle remaining crumble mixture evenly over the strawberries.
Bake for 40–45 minutes, until the top is golden and the filling is bubbly.
Remove from oven and place on a wire rack.

Cooling or Final Touches

Let the bars cool completely before slicing. This allows the filling to set and makes clean cuts possible.
