Preheat the oven to 350°
Line a loaf pan with parchment paper or grease and flour pan.
In a medium bowl mix flour, almond flour, baking powder and salt together, set aside.
In a large bowl, beat butter, maple syrup, orange juice, orange zest and egg together until blended.
Add flour mix into butter mix and beat until it blends together.
Add cocoa powder and milk into the empty bowl and blend until smooth.
Split the batter mixture evenly adding half of the batter into the bowl with the cocoa mixture. Stir to blend until mixed evenly.
Spoon alternate dollops of the mixture into the loaf pan, then use a skewer to create a marble pattern by dragging it through the mixture in swirls. Make sure you don’t overmix or you won’t see the pattern. Smooth the surface if necessary.
Bake the cake for 45 - 55 mins until golden and risen, and a skewer poked in center comes out clean.
Leave the cake in the pan to cool.
Melt the chocolate and coconut in the microwave for 30 seconds, stirring and cooking an additional 30 seconds, stirring chocolate until melted completely. Cook for additional time if needed.
Slowly pour chocolate over the cooled cake. Refrigerate until the chocolate has set.
Slice and enjoy.
