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.
