Ingredients

The Crumble

1 cup instant rolled oats
1 cup oat flour
2 cup unsweetened desiccated coconut
½ cup honey
⅓ cup coconut oil
1 teaspoon vanilla extract
¼ teaspoon salt
zest of 1 lemon

The Filling

2 ½ cup fresh blueberries
⅓ cup coconut sugar
1 tablespoon cornstarch
juice of ½ lemon

Instructions

Preheat oven to 350ºF (175ºC) using top and bottom heat, without the fan. Grease a 9-inch (23cm) square pan with some butter and then line it with parchment paper.

The Crumble

Add rolled oats, oat flour, desiccated coconut, honey, coconut oil, vanilla extract, salt, and lemon zest into a bowl. Mix everything well using a wooden spoon.
Pour ½ of the mixture into the prepared pan. Press evenly with your fingers. Set aside.

The Filling

Add blueberry, coconut sugar, cornstarch, and lemon juice into a bowl. Mix well using a spatula. Pour into the pan and spread evenly.
Sprinkle the other half of the crumble evenly on top.

Bake

Bake for 50 minutes on the lower ⅔ rack. Cover loosely with aluminum foil if the top browns too fast. I usually cover it at 20 minutes of baking time.
Cool completely before slicing. Enjoy!

Notes

Cool it completely before slicing or else it's going to break apart easily.
Use a kitchen scale for a more accurate measurement. I love to use it in bakings as baking is a science and needs to be precise.
Use a portable oven thermometer to get the accurate oven temperature. I use it every single time I bake.
