Before You Start

  • Prepare both batters separately

  • Do not overmix

  • Keep textures similar so they bake evenly

Method

1. Prepare the Vanilla Batter

Follow the standard vanilla cupcake method:

  • Cream the butter and sugar until light and smooth.

  • Add the eggs one at a time, mixing gently after each addition.

  • Alternate adding the dry ingredients and milk.

  • Add the oil and mix until just combined.

2. Prepare the Chocolate Batter

  • Cream the butter and sugar until light and smooth.

  • Add the eggs and mix gently.

  • In a separate bowl, whisk together the cocoa powder, flour, and salt.

  • Alternate adding the dry ingredients and milk.

  • Add the oil and mix until smooth.

3. Create the Marble Effect

  1. Line cupcake tray

  2. Add a spoon of vanilla batter

  3. Add a spoon of chocolate batter

  4. Repeat to fill each liner halfway–¾ full

  5. Use a toothpick or skewer to gently swirl

👉 Don’t over swirl — keep the pattern visible

4. Bake

  • Bake at 175°C (350°F)

  • For 18–22 minutes

  • Cool completely before frosting

What to Look For

  • visible swirl pattern

  • even rise

  • soft, moist texture

  • balanced vanilla + chocolate flavor

Common Mistakes

  • over swirling → muddy color

  • uneven batter thickness → uneven baking

  • overfilling → overflow

Tip

Keep the swirl minimal — a few gentle turns create the best marble effect.
