Cake Batter Buttercream Frosting

First, heat-treat the white cake mix. Pour the cake mix into a microwave-safe bowl. Heat the cake mix in the microwave for ⏱️ 30 seconds and then stir. Repeat this process until the cake mix reaches 160℉ (71℃), about 1-1½ minutes total. If the cake mix is lumpy, run it through a fine mesh strainer and then set aside to cool.

Add in the heavy cream, vanilla extract, and salt, and continue to mix on low speed until combined and smooth. Scrape the sides and bottom of the bowl to ensure the ingredients are well incorporated.

Increase the mixer speed to medium and whip the buttercream for about 3 to ⏱️ 5 minutes until it is smooth and creamy. Then, turn the mixer to low speed and mix the buttercream for several minutes to remove air bubbles.

Optional: To smooth out the buttercream, melt 1 cup of the frosting in the microwave for ⏱️ 15 seconds. Pour the melted frosting back into the mixing bowl and mix the frosting on low speed until the buttercream is super smooth and creamy.

Preheat the oven to 350℉ (177℃). Line a baking sheet pan with parchment paper.
