Peel the kiwis and cut them into small pieces. Preheat the oven to 180°C, fill the muffin tray with paper cups or grease them.
In a bowl, mix the dry ingredients, i.e. flour, baking soda, baking powder, cocoa powder and coconut flakes. In another bowl, beat the egg and whisk. Then add oil, granulated sugar, buttermilk, lemon flavouring, pineapple juice and the kiwi bits.
Now add the dry ingredients and mix everything briefly.
Place one tbsp. of batter into each muffin tin, then pour one tsp. of chocolate sauce into each tin and fill the tins with the remaining batter. Bake at 180°C on the middle shelf for 20-25 minutes, sprinkle the finished muffins with cocoa if necessary.
