Description
These Strawberry Oatmeal Bars are the perfect healthy treat—part buttery crumble, part juicy fruit pie. Made with wholesome rolled oats and a gluten-free flour blend, they feature a crisp, golden crust and topping sandwiching a layer of sweet, jammy strawberries. Simple to make and packed with fresh fruit flavor, they make a delicious breakfast, snack, or light dessert.
Ingredients
— The Crust & Topping —
1 cup gluten free old-fashioned rolled oats
3/4 cup gluten free all-purpose flour (ensure it contains xanthan gum)
1/3 cup light brown sugar, packed
1/4 teaspoon ground ginger
1/4 teaspoon salt
6 tablespoons unsalted butter, melted (or melted coconut oil)
— The Strawberry Filling —
2 cups fresh strawberries, diced small
1 teaspoon cornstarch
1 tablespoon fresh lemon juice
1 tablespoon granulated sugar
Instructions
1. Preheat & Prep: Preheat your oven to 375°F (190°C). Line an 8×8-inch square baking pan with parchment paper, leaving some overhang on the sides for easy removal.
2. Mix Dry Ingredients: In a medium bowl, combine the gluten free oats, gluten free flour, brown sugar, ground ginger, and salt. Whisk to combine.
3. Add Butter: Pour the melted butter over the dry mixture. Stir until the mixture forms moist, crumbly clumps and the dry ingredients are evenly coated.
4. Form Crust: Reserve 1/2 cup of the crumble mixture for the topping and set it aside. Press the remaining mixture firmly and evenly into the bottom of the prepared pan to form the crust.
5. Layer Filling: Scatter half of the diced strawberries over the crust. Sprinkle evenly with the cornstarch, lemon juice, and half of the granulated sugar. Scatter the remaining strawberries on top, followed by the remaining sugar.
6. Add Topping: Sprinkle the reserved 1/2 cup of oat crumble evenly over the strawberry layer.
7. Bake: Bake for 35–40 minutes, or until the fruit filling is bubbly and the oat topping is golden brown.
8. Cool: Allow the bars to cool completely in the pan on a wire rack. They need to set before slicing (chilling them in the fridge helps them slice cleanly).
9. Serve: Lift the bars out using the parchment paper overhang, slice into squares, and serve.
Notes
Oats: Ensure your oats are certified gluten-free if you have celiac disease. Old-fashioned rolled oats provide the best chewy texture compared to quick oats.
Dairy-Free Option: You can substitute the butter with melted coconut oil or a dairy-free butter alternative.
Storage: Store leftovers in an airtight container in the refrigerator for up to 5 days. They can also be frozen for up to 3 months.
