Preheat the oven to 180 degrees convection.
For the vegan "buttermilk", mix the vegetable drink of your choice with a teaspoon of apple cider vinegar and set aside. Leave the mix to stand for about 10 minutes until the liquid curdles.
Line a muffin tray with paper cups.
Meanwhile, mash the ripe banana with a fork to a fine mash.
Put the oat flakes, Lower Carb Sport Granola Raspberry-Almond-Coconut, linseed and baking powder in a large bowl and mix well.
Now add the sunflower oil and the vegan "buttermilk" and banana puree to the dry mixture and stir briefly. But don't stir too long so that the muffin mixture stays nice and fluffy.
Spoon or fork the batter into the prepared muffin tins, filling them about two-thirds full. Sprinkle some Lower Carb Sport Granola Raspberry-Almond-Coconut on top of each muffin.
Then bake the muffins in the oven at 180 degrees convection for about 25 minutes.
After the baking time, let the muffins cool down well.
