How to Make the Recipe

Step 1: Preheat and Prepare the Pan

Preheat your oven and line an 8×8 inch baking dish with parchment paper for easy removal.

Step 2: Mix the Crust and Crumble

In a bowl, mix together almond flour, oat flour, oats, and salt. Stir in melted butter, maple syrup, and vanilla extract until a crumbly dough forms.

Step 3: Form the Base

Press about two-thirds of the mixture firmly into the bottom of the prepared pan to create an even crust.

Step 4: Make the Strawberry Filling

In a separate bowl, combine diced strawberries, maple syrup, cornstarch, lemon juice, and almond extract. Mix until strawberries are evenly coated.

Step 5: Assemble the Bars

Spread the strawberry mixture evenly over the crust. Crumble the remaining dough over the top.

Step 6: Bake

Bake until the top is golden brown and the filling is bubbling. Allow to cool completely before slicing into bars.

Tips for Making the Recipe

Dice strawberries evenly for a more uniform filling.
Press the crust down firmly so it holds together well after baking.
Let the bars cool fully before slicing—they firm up as they cool.
Store in the refrigerator to maintain freshness and structure.
Use a sharp knife for clean, even cuts.

How to Serve

As a light dessert with a scoop of vanilla ice cream or yogurt
Paired with coffee or tea for an afternoon snack
Wrapped individually for school lunches or work snacks
Crumbled over a smoothie bowl or oatmeal
Dusted lightly with powdered sugar for presentation

Make Ahead and Storage

Storing Leftovers

Store in an airtight container at room temperature for 1–2 days or in the fridge for up to 5 days.

Freezing

Freeze the bars in a single layer, then transfer to a container or bag. Thaw in the fridge overnight before serving.

Reheating

These bars are best served cold or at room temperature, but you can warm them slightly in the microwave if desired.

FAQs

1. Can I use frozen strawberries?

Yes, but thaw and drain them first to avoid excess moisture in the filling.

2. What’s the difference between almond flour and almond meal?

Almond flour is finer and made from blanched almonds, giving a smoother texture. Almond meal is coarser and not ideal for this recipe.

3. Can I use honey instead of maple syrup?

Yes, but honey has a stronger flavor and slightly different texture, so results may vary.

4. Are these bars gluten-free?

They can be if you use certified gluten-free oats and oat flour.

5. Can I make these vegan?

Absolutely—use vegan butter or melted coconut oil as a substitute for regular butter.

6. Do I need to peel the strawberries?

No peeling needed—just wash, hull, and dice.

7. Can I use other fruits?

Yes, this recipe works well with raspberries, blackberries, blueberries, or even apples and peaches.

8. Why are my bars too soft?

Make sure to let them cool completely to allow the filling to set. You can also refrigerate them to firm up more.

9. How do I make oat flour at home?

Blend rolled oats in a high-speed blender until they become a fine powder.

10. Can I double the recipe?

Yes—use a 9×13 inch pan and adjust the baking time accordingly.
