Preheat the Oven: Preheat the oven to 180C / 350F / Gas Mark 5. Line an 8-inch square baking pan with baking parchment.
Prepare the Dry Ingredients: In a large bowl, combine the ground almonds, coconut flour, flaxseed, and baking soda.
Prepare the Wet Ingredients: In a separate bowl, whisk together the honey, maple syrup, and coconut oil. Blend in the almond butter a little at a time to make a thick, buttery paste.
Form the Dough: Add the wet ingredients to the dry, and rub together with your hands to form a dough. Set aside around a ¼ of the mixture.
Bake the Base: Press the remaining dough into the baking tin. Smooth it out with a spatula, then poke a few times with a fork all over. Bake in the preheated oven for 8 minutes.
Add the Jam Layer: Remove the tin from the oven. Spread the jam over the base, smooth out, then crumble the remaining dough all over the top. Finish with a few flaked almonds if you wish.
Finish Baking: Return to the oven and bake for another 10 – 12 minutes. When the top is lovely and golden, the slices will be ready.
Cool and Serve: Set aside to cool for around half an hour before you cut into squares! You can dust with coconut flour to serve.
