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.

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.

Bake at 175°C (350°F)
For 18–22 minutes
