1 1/2 cups (3 sticks) unsalted butter, softened to room temperature
1 cup unsweetened cocoa powder
3/4 teaspoon salt
4 cups powdered sugar
2 teaspoons pure vanilla extract
1/4 cup whole milk
3/4 cup heavy cream
2/3 cup Rich Chocolate Ovaltine powder
Cream together butter, cocoa powder and salt. Butter mixture will be very thick. Turn off the mixer, scrape down the sides of the bowl.
Add powdered sugar. Turn mixer on low and mix in powdered sugar while adding milk and vanilla extract. As the sugar incorporates, raise the speed of the mixer to beat the frosting. Beat until smooth, about 1 minute.
In a 2 cup measuring glass, stir together heavy cream and Ovaltine. Turn mixer speed to medium and pour half of the cream mixture into frosting in a slow, steady stream. Stop the mister scrape down the sides of the bowl. Add remaining cream mixture or until you’ve reached your desired consistency. Beat until soft and creamy, about 1 minute.
Store in an airtight container in the refrigerator or freezer. Bring to room temperature before frosting cakes and cupcakes.
