Cupcake Preparation:
Preheat the oven to 180°C (350°F) standard / 160°C (320°F) fan-forced. Line a 12-hole muffin tin with cupcake liners.
Sift together flour, cocoa, baking soda, and baking powder. Stir in both sugars.
In a separate bowl, whisk softened butter with eggs and vanilla.
Mix dry and wet ingredients alternately with buttermilk, until just combined.
Fill cupcake liners with batter, bake for 18-20 mins. Cool before coring and filling with Mini M&Ms.
Frosting Preparation:
Cream butter until smooth. Gradually add icing sugar and milk to desired consistency.
Split frosting into three bowls, tint each with different food coloring.
In a piping bag with a large star tip, carefully layer each color.
Decorating:
Pipe a rainbow swirl on each cooled cupcake.
Baking Tips:
Ingredients like butter and eggs should be at room temperature.
Avoid overmixing to keep the cupcakes light.
Gently layer the frosting colors in the piping bag for perfect rainbow swirls.
