Peanut Butter Cake with Malted Chocolate Frosting

Peanut Butter Cake with Malted Chocolate Frosting. A stunning pair and the most addictive & delicious combination. This tender crumb is flavored with peanut butter all throughout. It’s topped with a luscious malted frosting. And it’s definitely one of my favorites.  

I love all things malt and in this buttercream pairs wonderfully with the peanut butter, given it’s nutty and toasty flavor. 

I used Ovaltine for the buttercream. It’s such a fun ingredient to use! Whenever I see it on the selves, my mind instantly goes back to that 90’s commercial “more Ovaltine, please!” It’s a classic. 

Malted Chocolate Frosting

How to make malted chocolate buttercream

  • Beat room temperature butter and salt until smooth and creamy. I use a stand-mixer fitted with a paddle attachment. You can also use a hand held mixture 
  • Add in the powdered sugar, cocoa powder, Ovaltine or malted milk powder and beat until very thick and well combined. 
  • Lastly add in the vanilla and milk or cream, 1 tbsp at a time. Continue to mix on high until the frosting is light and fluffy. 

The chocolate malt doesn’t overpower the frosting at all. It adds a delicious toasty note with hints of carmel that makes this a peanut butter & chocolate lovers DREAM. If you can’t find the Ovaltine brand, Carnation also makes a malted milk powder in original and chocolate.

What is malted milk powder?

  • Malted milk powder is a shelf stable product that is made from barley, wheat flour and evaporated milk. And it also comes in chocolate flavor.

When baking with peanut butter, the creamy kind is best! There’s a time and place for the all-natural kind. It can get a bit pasty. This Peanut Butter Cake with Malted Chocolate Frosting is perfectly moist with all the best flavors.

    […] They have a chocolate chip cookie base that is made with both whole wheat and all purpose flour. The whole wheat flour gives this blondie a toasty flavor, just like a graham cracker. Plus the addition of malted milk powder adds an extra layer of warm & toasty flavor. I use malted milk powder often in my recipes, you can also find it in this malted chocolate frosting. […]
