Preheat your oven to 180°
Grease a medium sized cake pan and line the bottom with baking paper
Cream together the butter and sugar until light and fluffy - you can do this in a stand mixer or by hand using a whisk
Add the eggs (one at a time), mixing until incorporated.
Add almond milk and vanilla and beat until incorporated.
In a separate bowl, whisk together the ground almond, coconut flour, baking powder, baking soda and salt
Add the dry ingredients to the wet and mix thoroughly. Don't panic. It may not look like cake batter at this point.
Spoon the batter into your prepared pan and bake for 35 to 40 minutes, but you will know the cake is ready as it will be golden brown and starting to pull away from the sides
Let the cake cool in the pan for an hour
