Ingredients
  

Cupcake Base

  • 1/3 Cups Cocoa powder
  • 1 Tsp Baking Powder
  • 1/2 Tsp Baking Soda
  • 1/4 Tsp Salt
  • 2 Eggs, Large
  • 1/2 Cup Milk
  • 120 mls Vegetable Oil
  • 1 Tsp Vanilla Extract
  • 1/3 Cup Hot Water/Coffee
Buttercream Frosting
  • 250 g Unsalted butter
  • 3-4 Cups Icing sugar
  • 1 Tsp Vanilla Extract
  • 2-3 Tbsp Milk
  • Gel Food Colorings as needed
Decorations (Optional)
  • 24-36 Candy eyeballs

Method
 

  1. Preheat oven to 175°C (350°F) and line a 12-hole muffin tray with cupcake liners.
  2. In a large bowl, whisk together plain flour, caster sugar, cocoa powder, baking powder, baking soda, and salt.
  3. In a separate bowl, whisk eggs, milk, vegetable oil, and vanilla extract until well combined.
  4. Add the wet ingredients to the dry ingredients and mix until just combined. Do not overmix.
  5. Slowly pour in the hot water or coffee and stir until the batter is smooth and slightly runny but still thick enough to scoop.
  6. Divide the batter evenly between cupcake cases, filling each about two-thirds full.
  7. Bake for 18–22 minutes, or until a skewer inserted into the centre comes out clean.
  8. Allow cupcakes to cool in the tray for 5 minutes, then transfer to a wire rack to cool completely before decorating.
  9. To make the buttercream, beat the softened butter until pale and fluffy.
  10. Gradually add icing sugar, vanilla extract, and milk, beating until smooth and thick.
  11. Divide buttercream into bowls and colour each with gel food colouring.
  12. Pipe buttercream onto cooled cupcakes using a star or grass piping tip to create a “monster fur” effect.
  13. Immediately decorate with candy eyes, sprinkles, marshmallows, chocolate chips, or pretzel horns before the frosting sets.
  14. Serve and enjoy your Monster Cupcakes.

Notes

These Monster Cupcakes are designed to be simple, flexible, and fun, so don’t worry about perfect piping or identical decorations—each cupcake is meant to look unique.
For best results, always use room temperature ingredients, especially eggs and milk, as this helps create a smoother batter and more even rise.
The hot water or coffee in the batter helps enhance the chocolate flavour and keeps the cupcakes moist, but the batter should still remain thick and scoopable, not watery.
Gel food colouring is recommended for the buttercream as it gives stronger, more vibrant monster colours without thinning the frosting.
Make sure cupcakes are completely cooled before decorating to prevent the buttercream from melting or sliding off.
Decorations can be customised based on what you have available, making this a great “use what you’ve got” Halloween recipe.
These cupcakes are best served fresh but can be made ahead and decorated on the day of serving for maximum visual impact.
