Step-By-Step Instructions 👇👇

STEP 1: Sift Dry Ingredients

Add the ¼ cup sifted cocoa powder and 1 cup powdered sugar to a flour sifter or fine mesh strainer to help prevent clumps. Transfer the sifted mixture to a medium bowl.

Chocolate frosting ingredients are mixed together until smooth.

STEP 1: Mix Together

Melt 2 Tbsp butter in the microwave. Add it to the powdered mixture along with 2 Tbsp milk, and ¼ tsp vanilla extract. Beat with a whisk or hand mixer until smooth and creamy. Drizzle or spread over your cake, cupcakes or brownies and serve!

Note: If the frosting seems too thick, add 1 more tablespoon of milk and mix again until it reaches your desired texture.

Recipe Tips

Sift the cocoa powder to prevent clumps
Use heavy cream instead of milk for a richer texture
For a thinner frosting (great for drizzling), add a splash more milk
Doubles easily for 9x13 cakes or layer cakes
Use while still slightly warm—it spreads beautifully

FAQs

Help! My Frosting is Lumpy

This can definitely happen but it will still taste really good! I recommend sifting the cocoa powder and powdered sugar to avoid clumps. I also recommend using an electric mixer and mixing for 2-3 minutes to help prevent this.

Can I make old-fashioned chocolate frosting ahead of time?

Yes—store in the fridge and re-whip or stir before using. You may need to bring it to room temperature first.

Can I use this on cupcakes or brownies?

Absolutely. It’s great for any baked good and sets with a soft, glossy finish. It’s also delicious on layer cakes or rich desserts like Double Chocolate Cheesecake.

Is this the same as fudge frosting?

Not quite—this one is a little lighter and more spreadable, but has that same rich, cocoa-forward flavor.
