Ingredients
For the Strawberry Filling:
- 2 cups fresh or frozen strawberries, chopped
- 2 tablespoons granulated sugar (or honey)
- 1 tablespoon lemon juice
- 1 tablespoon cornstarch (to thicken)
- 1/2 teaspoon vanilla extract
For the Oatmeal Crust and Crumble:
- 1 1/2 cups old-fashioned rolled oats
- 1 cup all-purpose flour
- 1/2 cup light brown sugar (packed)
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1/2 teaspoon ground cinnamon (optional, but recommended)
- 1/2 cup unsalted butter, cold and cut into small cubes
- 1/4 cup honey or maple syrup (optional, for added sweetness)
- 1/2 teaspoon vanilla extract
Directions to follow
-
Start with the strawberry filling. In a small saucepan, combine the chopped strawberries, granulated sugar (or honey), lemon juice, cornstarch, and vanilla extract. Cook over medium heat, stirring occasionally. Once it reaches a simmer and thickens (about 5-7 minutes), remove it from the heat and let it cool while you prepare the next steps.
-
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease it to prevent sticking.
-
In a large mixing bowl, combine the oats, flour, brown sugar, baking powder, salt, and optional ground cinnamon.
-
Add the cold butter cubes. Using a pastry cutter, fork, or your hands, blend the butter into the dry ingredients until the mixture resembles coarse crumbs. It should be crumbly yet stick together when pressed.
-
Mix in the vanilla extract and honey or maple syrup if you desire additional sweetness. You want a nice crumbly dough at this point.
-
Press about 2/3 of the crumble mixture evenly into the bottom of your prepared baking pan to form the base.
-
Spoon the cooled strawberry filling over the oatmeal base, spreading it evenly.
-
Sprinkle the remaining crumble mixture over the strawberry filling. Press it gently down for a cohesive top layer.
-
Bake in the preheated oven for 35-40 minutes, until the top is golden brown and the filling is bubbling. To check if it’s done, insert a toothpick into the crumble top—it should come out clean or with just a few crumbs.
-
Allow the bars to cool completely in the pan on a wire rack. The filling will firm up as it cools. Once completely cooled, lift the bars out using the parchment paper (if used) and slice them into squares or rectangles.
Best ways to enjoy it
These Strawberry Oatmeal Crumble Bars are versatile! They can be served warm or at room temperature. For a delightful twist, consider topping them with a scoop of vanilla ice cream or a dollop of whipped cream. You can also pair them with a side of yogurt for a delightful breakfast or snack option. Garnish with fresh mint for a pop of color and a hint of freshness.
Storage and reheating tips
To keep your crumble bars fresh, store them in an airtight container at room temperature for up to three days. If you want to keep them longer, they freeze beautifully! Just wrap them tightly in plastic wrap and then in aluminum foil. They can be frozen for up to three months. When you’re ready to enjoy, simply let them thaw at room temperature, or warm them up in the oven for a few minutes to regain that delightful crisp.
Helpful cooking tips
- Make sure your butter is cold when adding it to the dry ingredients; this helps create that perfect crumble texture!
- If using frozen strawberries, there’s no need to thaw them. They’ll cook down beautifully and still give you that delicious filling.
- Feel free to adjust the sweetness of your filling based on your strawberry’s ripeness.
Creative twists
Get adventurous with your flavor combinations! Instead of strawberries, why not try blueberries or raspberries? You could also mix in some chopped nuts or coconut flakes into the crumble for added texture. For a tropical change, use mashed bananas in the filling and pair with a sprinkle of toasted coconut on top. The possibilities are endless!
