Gausi's black and white muffins

Ingredients for 12 servings:

• 250 g egg(s) , (weigh)
• 220 g sugar
• 250 g butter, soft
• 250 g flour, type 405
• 40 g cocoa powder
• 1 tsp baking powder
• possibly milk
• powdered sugar

Instructions

Working time approx. 15 minutes; Total time approx. 15 minutes

Preheat the oven to 180°C. Sift the flour into a bowl and mix well with the baking powder. In a mixing bowl, beat the eggs and sugar with a hand mixer until very fluffy, at least 5 minutes, then gradually add the butter while stirring. Now add the flour mixture to the egg mixture and beat for another 5 minutes. Divide the batter in half and stir the cocoa powder into one half, thinning with a little milk if necessary. Grease a muffin tin well with butter. Fill the holes two-thirds full with the light batter, then the dark batter. Carefully pierce the holes with a spoon handle or wooden skewer to create a marbled texture. Bake for 20-25 minutes until golden brown. Remove the muffins from the oven and let them rest in the tin for another 5 minutes. Turn them out of the tin and let them cool on a wire rack. Sprinkle with powdered sugar. Tip: The fluffiness of the finished muffins depends on how you mix the foam mixture and later the entire batter! So it’s better to mix for longer than too little, or to resort to using a food processor.
