Cooking Instructions

Follow these simple steps to prepare this delicious Strawberry Rhubarb Crumb Bars:

Step 1: Preheat Your Oven

Preheat your oven to 350°F (175°C). Prepare an 8×8-inch baking dish by greasing it with nonstick spray or lining it with parchment paper for easy removal.

Step 2: Prepare Your Fruit

In a bowl, combine sliced strawberries and chopped rhubarb with granulated sugar. Let this mixture sit while you prepare the crust and crumb topping; this allows all those juicy flavors to mingle.

Step 3: Make the Crust

In another bowl, mix melted butter with brown sugar until smooth. Add flour, rolled oats, baking powder, and salt; stir until combined. Press two-thirds of this mixture evenly into your prepared baking dish as the base layer.

Step 4: Add The Fruit Filling

Spread the strawberry-rhubarb mixture evenly over the crust. It will look fabulous—like nature’s confetti on top of a buttery canvas!

Step 5: Create The Topping

Take the remaining crumb mixture from Step 3 and sprinkle it generously over the fruit filling. Don’t hold back! This is where all that crumbly goodness happens.

Step 6: Bake

Bake in your preheated oven for about 35-40 minutes until golden brown on top and bubbly around the edges. Your kitchen will smell heavenly!

Let it cool before slicing into squares. Transfer to plates and serve warm or at room temperature for an unbeatable dessert experience! Enjoy every delightful bite of these Strawberry Rhubarb Crumb Bars as they transport you straight back to those cherished family gatherings!
