Preheat the oven to 350°F (175°C).
Grease a 9-inch round cake pan and set aside.
In a large bowl, whisk together almond flour, cocoa powder, baking powder, and a pinch of salt.
In another bowl, beat together eggs, melted butter, sweetener, almond milk, and vanilla extract.
Gradually add the wet ingredients into the dry ingredients and mix until smooth.
Pour the batter into the prepared cake pan and spread evenly.
Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Let the cake cool completely on a cooling rack.
Whip the heavy cream and sweetener until soft peaks form, then add the mint extract and mix.
Spread the mint cream evenly over the cooled cake.
Melt the chocolate chips and drizzle over the mint cream layer.
Refrigerate for at least 2 hours to set.
