Preheat Oven: Set your oven to 356ºF (180ºC). Line a 9 x 9 inch square baking pan with parchment paper and set aside.
Mix Dry Ingredients: In a medium-sized mixing bowl, whisk together the almond meal and cocoa powder. Set aside.
Melt Chocolate and Oil: Set up a double boiler with a heat-proof bowl over simmering water and add the broken up chocolate and coconut oil. Melt over low-medium heat until smooth and shiny.
Add Sugar: Once the chocolate is completely melted, remove from heat. Add sugar and whisk until the sugar has dissolved.
Cool Chocolate Mixture: Allow the chocolate mixture to cool slightly for about 10 - 15 minutes until it’s no longer hot to the touch otherwise your eggs will curdle when added.
Add Vanilla and Eggs: Pour in the lightly whisked eggs and vanilla and whisk until well combined.
Combine with Dry Ingredients: Add the almond and cocoa mixture to the chocolate mixture and gently fold until incorporated. Avoid overmixing.
Fold in Blueberries: Fold through one cup of the blueberries.
Prepare Baking Tin: Pour the batter into the prepared baking tin. Scatter the remaining half a cup of blueberries over the top.
Bake: Bake for 25-30 minutes, or until the brownie springs back when touched, and a skewer inserted into the middle comes out with a few moist crumbs, not wet batter. Slightly underbaking brownies will keep them fudgy.
Cool: Remove from the oven and allow to cool in the pan for 15 minutes before transferring to a wire rack to cool completely. Cut into squares and enjoy!
