Fudgy Chocolate Frosting (Made in One Bowl)

A quick and easy chocolate buttercream made in one bowl! Rich cocoa flavor, creamy texture, and perfect for frosting cakes, cupcakes, or brownies.
Prep Time15 minutes
Total Time15 minutes
Course: Dessert
Cuisine: American
Servings: 3 cups

Ingredients

  • 1 cup unsalted butter softened
  • 2/3 cup natural cocoa powder sifted
  • 2 ½ cup powdered sugar sifted
  • 1/4 cup heavy cream at room temperature, plus more as needed
  • 2 tsp pure vanilla extract
  • 1/4 tsp fine sea salt

Instructions

  • In a large bowl using a hand mixer or stand mixer, beat the softened butter on medium speed until creamy and pale, about 2–3 minutes.
    1 cup unsalted butter
  • Add the sifted cocoa powder and mix on low speed until well incorporated. Scrape the sides of the bowl to ensure it’s evenly blended.
    2/3 cup natural cocoa powder
  • Gradually add the sifted powdered sugar, alternating with a little heavy cream. Mix on low until incorporated, then increase to medium and beat until smooth and fluffy.
    2 ½ cup powdered sugar, 1/4 cup heavy cream
  • Beat in the vanilla extract and salt. Mix for 1–2 more minutes. If the frosting is too thick, add more cream 1 tablespoon at a time. If it’s too soft, add a bit more powdered sugar.
    2 tsp pure vanilla extract, 1/4 tsp fine sea salt
  • For a fluffier texture, whip on high speed for another 2–3 minutes. For a fudgier, denser feel, stop mixing once it’s fully combined and smooth.

Notes

Makes enough for:
• 12 cupcakes (generously)
• 1 layer cake (9x13 or two 8-inch layers)
💡 Pro Tips
• For extra richness, you can use dark cocoa powder or swap half the butter for brown butter.
• If frosting a warm cake, make sure the cake is fully cooled or chilled to avoid melting.
• Stores well in the fridge for up to 5 days. Bring to room temp and re-whip before using.
