Few weeks ago, on a unexpected sunny days after a week of rain I decided to do some spring cleaning. It was time to declutter a little bit, out with the old, make room for the new.

I was doing so well, without a distraction until I found an old recipe binder. You know, the one post blog and pinterest. Old magazine clippings, printed recipes from various websites. That was the end of my spring cleaning. I made myself a big cup of coffee and browsed though all those yellowed pages, some of them with grease and batter stains on them. Others have hand written notes on the side, comments on how the recipe turned out. After a good 30 minutes of reading through the clippings and notes I found a recipe for a peanut butter and chocolate cake torn from an old Gold Medal Flour booklet.

I don’t know how old the recipe may be or how it landed into my binder, but it sure sounded too good not to try it. 

 

Peanut butter and chocolate cake squares recipe from Roxanashomebaking.comFew hours later, after somehow finishing my spring cleaning I found myself in the kitchen whipping up this one super easy peanut butter and chocolate cake. 5 minutes of prep time, top! Just perfect for this busy mama.

You start by dumping all the ingredients in a mixing bowl and mix for few seconds on low speed. With a spatula scrape the sides of the bowl and mix again, this time on high speed for 2-3 minutes.

That’s it! I told you it’s most likely the easiest cake I’ve shared on this blog.

To make the marble design, mix the cocoa powder with a little bit of the peanut butter batter and with a fork or butter knife make few swirls. Place it in the oven and bake for about 40 to 45 minutes.

Once the cake is done it’s very important to let it cool completely before cutting it into squares, and decorate with chocolate ganache and peanut butter frosting. Now, of course I won’t blame you if you don’t want to do that and you dig right in. I’m totally on your side!

As much as I don’t like to admit it, I’ve come to the conclusion that chocolate and peanut butter is one of the most frequent combo on this blog. After months and months of putting it away, I can’t postpone it any longer! May is peanut butter and chocolate month.

And I’m not the only one thinking so. Not at all! My wonderful chocolate lovers party friends are all here with treats for everyone!

    This recipe looks amazing… but I’m afraid to make it because it looks like an ingredient is missing. Step six says “Stir cocoa into remaining batter. Drop chocolate batter onto peanut butter batter”, yet I do not see cocoa listed in the ingredients for the recipe. Help?

    • says

      Cocoa is listed in the ingredients list.

      3 tablespoons (15 grams) unsweetened baking cocoa

      it’s the last one of the list, just above the ingredients for the ganache
