Equipment Needed

  • Mixing bowls
  • Spoon or spatula
  • 9×9-inch baking dish
  • Measuring cups and spoons

How to Make This Recipe

Step 1 – Prepare the Strawberry Filling

Start by washing and chopping the strawberries. In a medium bowl, combine the chopped strawberries, granulated sugar, corn starch, and water. Mix gently until the strawberries are coated. Let it sit for about 10 minutes to allow the sugar to draw out the juice.

Step 2 – Mix the Oatmeal Crust and Crumb Topping

In a large bowl, combine 1 3/4 cups of the flour, 1 cup of the oats, baking soda, and salt. In a separate bowl, whisk together the melted coconut oil, brown sugar, egg, and vanilla extract. Pour the wet ingredients into the dry mixture and stir until just combined. It should be crumbly but hold together when pressed.

Step 3 – Assemble and Bake

Preheat your oven to 350°F (175°C). Grease your baking dish. Press half of the oatmeal mixture into the bottom of the dish to create a crust. Spread the strawberry filling over the crust, then sprinkle the remaining oatmeal mixture on top. Shake a little coarse sugar over the top for added sweetness, if desired. Bake for about 30 to 35 minutes, or until the top is golden brown. Allow the bars to cool completely in the pan before cutting them into squares.

Tips for Perfect Results

To ensure your Strawberry Oatmeal Crumb Bars turn out perfectly, consider these tips:

  • Always use fresh strawberries whenever possible for the best flavor.
  • Let the bars cool completely before cutting to help them maintain their shape.
  • If the filling seems too runny, you can add a bit more cornstarch to thicken it.
  • Be sure to press the crust firmly into the pan; this helps it hold together better.
  • Store the bars in an airtight container for maximum freshness.

Flavor Variations

You can mix things up with these flavor variations:

  • Add a teaspoon of cinnamon to the crumb topping for a warm spice.
  • Swap out strawberries for blueberries or raspberries for a different berry flavor.
  • Mix in a handful of chopped nuts for a crunchy texture.
  • Add a bit of lemon zest to the filling for a citrusy kick.
  • Use honey or maple syrup instead of brown sugar for a different sweetness.

What to Serve With This Recipe

These Strawberry Oatmeal Crumb Bars make a lovely dessert or snack on their own. Here are some pairing ideas:

  • Serve with a scoop of vanilla ice cream for a delightful combination.
  • A dollop of whipped cream on top adds a nice touch.
  • Pair with a hot cup of tea or coffee for an afternoon treat.
  • Offer with fresh fruit on the side for a colorful display.
