In a mixing bowl, add protein powder, crushed Biscoff biscuits and baking powder and stir well to combine.
Crack in the egg, and whisk to combine into the dry ingredients.
Once combined, fold through the yoghurt and add milk as necessary.
Pour half the batter into a greased mug, ramekin or muffin case.
Place the softened Biscoff in the centre, saving some to drizzle on top after. Then cover with remaining batter.
Place in the @panasonic_au 3-in-1 Combination microwave and bake on the Convection setting at 150C for 10 minutes.
Serve while it’s still warm with a drizzle of extra Biscoff spread, vanilla ice cream and caramel sauce. Enjoy!
