How To Make The Chocolate Frosting 👇👇
Classic Chocolate Frosting Ingredients
- 2 Tbsp butter
- 1 cup powdered sugar
- ¼ cup unsweetened cocoa powder, sifted
- 2-3 Tbsp milk (start with 2 Tbsp and add 1 more if needed)
- ¼ tsp vanilla extract
STEP 6: Melt
In a small saucepan or microwave safe bowl, melt 2 Tbsp butter.
STEP 7: Mix
In a medium bowl, add the melted butter, ¼ cup unsweetened cocoa powder, sifted, 1 cup powdered sugar, 1 Tbsp milk, and ¼ tsp vanilla extract. Stir until smooth and creamy. Add an extra splash of milk if needed until you reach desired consistency.
STEP 8: Frost
Spread frosting evenly over the cooled cake. Slice into 9 squares and serve.

Recipe Tips
- Line the pan with parchment paper for easy flipping and clean edges
- Soften the butter fully before mixing for a smoother batter
- Let the cake cool completely before frosting so it spreads evenly
- Add a pinch of salt to the frosting to balance the sweetness
Common Mistakes To Avoid
- Sift your cocoa powder to avoid clumps and get that smooth, even batter
- Use hot water straight from the kettle-it helps bloom the cocoa for better flavor
- Watch your bake time-too long and it'll dry out, too short and the center can sink
- Let the cake cool fully before frosting so you don't end up with a melted mess
- Stick with real butter for the best taste and texture-margarine just doesn't cut it
Variations & Substitutions
- Use hot coffee instead of water for a richer chocolate flavor
- Add ½ cup mini chocolate chips for extra texture
- Substitute vegan butter and milk to make it dairy-free
- Add a pinch of cinnamon or espresso powder to deepen the flavor

FAQs
Yes! You can scoop the batter into a lined muffin pan and bake at 350°F for 20-22 minutes. Just note-it won't make a full dozen. You'll get around 8-9 cupcakes from one batch.
Absolutely. Double the ingredients and divide the batter between two 8-inch round pans. Bake for 40-45 minutes, then frost one layer, stack the second, and finish with more frosting on top.
Totally. It's still rich and chocolatey on its own-the perfect snacking cake! You can dust it with a bit of powdered sugar if you want to keep it simple
