Mix the sugar, flour, baking powder, salt and almonds in a bowl. Mix the oil, egg, vanilla extract and buttermilk in a second bowl. Then mix with the dry ingredients.
Pour 1 tablespoon of the batter into each muffin case. Place a Raffaello praline in the middle. Spread the remaining dough on top so that the molds are 2/3 full.
Bake muffins for 15-20 minutes.
For the cream, melt the white chocolate and let it cool down a little. Beat the butter and powdered sugar. Stir in the vanilla extract, cream cheese, a pinch of salt and chocolate. Let cool in the fridge.
Spread the cream over the muffins using a piping bag and decorate with a Raffaello praline.
