Step-by-Step Instructions for Triple Chocolate Cornflake Crunch Cake
1. Prepare the Oven
Preheat the oven to 350°F (175°C).
Grease two 8-inch cake pans and line the bottoms with parchment paper.
2. Mix the Dry Ingredients
In a large bowl combine:
- Flour
- Cocoa powder
- Baking powder
- Baking soda
- Salt
Whisk until evenly mixed.
3. Mix the Wet Ingredients
In another bowl combine:
- Sugar
- Eggs
- Milk
- Oil
- Vanilla
Whisk until smooth.
4. Combine the Batter
Gradually add the dry ingredients to the wet ingredients.
Mix until just combined.
Slowly pour in the hot coffee or hot water while stirring.
The batter will be thin. This creates an extra moist cake.
5. Bake
Divide the batter evenly between the prepared pans.
Bake for 30–35 minutes.
A toothpick inserted into the center should come out with only a few moist crumbs.
6. Cool Completely
Let the cakes cool for 10 minutes.
Remove from the pans.
Transfer to a cooling rack until completely cool.
7. Prepare the Buttercream
Beat the butter until fluffy.
Gradually add powdered sugar and cocoa powder.
Mix in vanilla.
Add milk one tablespoon at a time until smooth and spreadable.
Finish with a pinch of salt.
8. Make the Chocolate Ganache
Heat the cream until steaming.
Pour over chopped chocolate.
Let sit for two minutes.
Stir until glossy and smooth.
Allow to cool slightly.
9. Prepare the Cornflake Crunch
Melt the milk chocolate with butter.
Stir in cocoa powder.
Fold in cornflakes gently until evenly coated.
Spread onto a parchment-lined tray.
Allow to cool until crisp.
Break into small crunchy pieces.
10. Assemble the Cake
Trim the cake tops if needed.
Place one cake layer onto a serving plate.
Spread a generous layer of buttercream.
Sprinkle plenty of chocolate cornflake crunch over the frosting.
Place the second cake layer on top.
11. Frost the Cake
Cover the entire cake with buttercream.
Smooth the sides using an offset spatula.
Chill for 20 minutes.
12. Add Ganache
Pour the ganache over the top.
Allow it to drip naturally down the sides.
13. Decorate
Press extra cornflake crunch around the edges.
Top with chocolate curls, chocolate chips, or chocolate shavings.
Let the cake rest for 30 minutes before slicing.
