🥣 Ingredients You Will Need
- Flour – All-purpose flour works well in this recipe. I recommend using a digital kitchen scale, because flour can be very tricky to measure. But, if you’re using measuring cups, make sure to use the spoon-and-level method. Spoon the flour into the measuring cup and then level off any excess flour with the back of a knife.
- Rolled oats – Use old-fashioned rolled oats, not quick oats. This gives the bars a nice chewy texture, whereas quick oats are too soft and will turn into mush while baking.
- Sugar – Use regular, granulated sugar or replace it with coconut sugar to make the bars free from refined sugar.
- Vanilla extract – Adds the distinct sweet aroma. The higher the quality of your vanilla extract, the better the taste.
- Coconut oil – Use refined coconut oil, which has a practically non-existent coconut flavour. If you’re using measuring cups, make sure to measure melted coconut oil.
- Strawberries – It’s best to use fresh strawberries. I wouldn’t recommend using frozen fruits for this recipe, as the bars might turn out too soggy.
- Cornstarch – Thickening agent that helps to create that creamy fruit filling.
- Agave syrup – Slightly sweetens the filling. You can replace it with sugar or a different liquid sweetener.
📝 Substitutions and Variations
- Make them gluten free – Replace all-purpose flour with the same amount of gluten-free flour blend that's suitable for baking.
- Add some crunch – You can add chopped almonds, pecans or walnuts to the topping for extra flavour and texture.
- Make them refined sugar free – Swap out the granulated sugar for coconut sugar.
📋 Step-by-Step Instructions
Step One: Make the strawberry filling.
Roughly chop strawberries into equally sized pieces. In a large mixing bowl, toss them with agave syrup and cornstarch, then set aside.
Step Two: Make the crumble.
Mix flour, rolled oats, sugar and vanilla together, then drizzle over melted coconut oil. Mix to combine. The texture should be slightly crumbly, with several lumps sticking together.
Step Three: Press in the crust and bake it.
Press two thirds of the crumble into the base of the prepared baking tin, and prick the base gently with a fork. Bake the base for 20 minutes or until it is golden brown.
Step Four: Add filling.
Remove the pre-baked crust from the oven and spread the mixture evenly over the oat crust.
Step Five: Add the crumble and bake.
Sprinkle the strawberries with the remaining third of the dough and place the tin back in the oven. Bake for another 30 to 35 minutes, until the top is golden brown and the filling starts to bubble slightly.
Step Six: Cool, slice and serve!
Remove the pan from the oven and wait for it to cool down completely, then slice it into 9 bars.
