I'm back...sort of. I know I haven't posted in forever, and to be honest this blog has felt more like my personal recipe book. In that vein, I needed a place to not lose this recipe, so here I am. This is the fourth year in a row that Jake has asked for a chocolate cake with a peanut butter swirl and peanut butter frosting. The first year I just sort of threw it together without measuring or writing anything down. As anyone who learned to cook this way knows, it is very hard to replicate. The next year I tried measuring and writing it down, but I wasn't as happy with it so I tossed my very sophisticated post-it note list of ingredients in the trash. Last year it came out great...but I didn't take a single picture. This year I was determined to make a permanent place on the internet for this gorgeous cake. I only got a couple of pictures, but they will have to suffice.
It starts out with a basic chocolate cake. I like to use the Hershey's Perfectly Chocolate Chocolate Cake recipe. It always turns out delicious and moist (sorry, for all of you that hate that word) with a tender crumb. Then you dollop in some peanut buttery goodness, give it a good swirl and you have a perfect cake for the chocolate & peanut butter lovers in your life.
Start out by mixing together your dry ingredients: sugar, flour, cocoa powder, baking powder, baking soda, and salt. For the cake pictured, I used dark cocoa because frankly, I prefer it. Feel free to use regular cocoa powder if you like that better. Add in the eggs, milk, vegetable oil, and vanilla and mix on medium speed with your mixer for 2 minutes. At this point your batter will look smooth and beautiful and you will think you should put it in the pans, but you are mistaken. Stir in the boiling water until fully combined. It will be VERY liquidy and you will think you have ruined your cake, but you have not.
While your mixer is doing all the work for your cake batter, melt the peanut butter and butter in a large microwave safe measuring cup in 30 second bursts until melted and smooth. Then add the powdered sugar, a little vanilla, and a pinch of salt. Mix it together until smooth.
Spray two nine-inch pans with baking spray and pour the cake batter evenly between the two. Then pour the peanut butter mixture all over the top. Take a knife and swirl the peanut butter mixture into the batter. If you want to lick that knife when you are finished, I won't tell. This stuff is delicious!
Put the cake pans into a 350 oven for 30-35 minutes or until a toothpick in the center comes out with only moist crumbs. I usually rotate my pans halfway through because one side of my oven is hotter than the other. When you cake is finished, let it cool in the pans for about 10 minutes before you take it out of the pans to cool the rest of the way. It is so pretty, it's hard to cover it with frosting.
Once the cake is completely cooled you can frost it, but I personally like to freeze my cake layers wrapped in plastic wrap and a ziplock. I find that it is easier to frost cakes when the layers are frozen. We can't get enough peanut butter in this house so I make a peanut butter buttercream to frost this and then decorate with chocolate sprinkles and mini Reese's. If you want to do the same, I've included my frosting recipe below. I will say that this frosting is really delicious, but is difficult to get smooth so it will not be your most beautiful cake. That being said, once you take a bite, you will not care.
I always store this cake in the fridge. This cake is incredibly rich and the perfect mix of sweet from the chocolate and salty from the peanut butter. I hope you like it as much as we do!

Peanut Butter Swirl
- 3/4 cup creamy peanut butter
- 4 tlbs. butter
- 1/3 cup powdered sugar
- 1/2 tsp. vanilla
- pinch of salt
- Preheat oven to 350. Spray two 9-inch round cake pans with baking spray.
- Stir together sugar, flour, cocoa powder, baking powder, baking soda, and salt in the bowl of the mixer.
- Add in eggs, milk, vegetable oil, and vanilla. Beat on medium speed on your mixer for two minutes.
- Stir in boiling water.
- Pour evenly between the two pans.
- To make the peanut butter swirl, melt the peanut butter and butter in a large liquid measuring cup (covered) in the microwave in 30 second bursts, stirring and recovering in between.
- Add the powdered sugar, vanilla, and a pinch of salt to the peanut butter mixture and stir until smooth.
- Pour the peanut butter mixture over the top of the cake batter and use a knife to swirl it into the batter.
- Bake at 350 for 30-35 minutes, or until a toothpick in the center comes out with only moist crumbs attached.
- Cool in the pans for about 10 minutes. Then turn out onto cooling racks to cool completely before frosting.
- If using the peanut butter frosting below, be sure to refrigerate the cake after frosting it.
- 1/2 cup butter
- 1/2 cup butter flavored crisco stick
- 1 cup creamy peanut butter (I used JIF)
- 3 cups powdered sugar
- 1 tbls. meringue powder
- 1 tsp. vanilla extract
- 2 tbls. milk
- 1 to 1 1/2 tsp. salt (to taste)
- Cream butter, Crisco, and peanut butter until combined and smooth.
- Add powdered sugar and meringue powder and mix until combined (you will probably need to stop and scrape once or twice). *I like to wrap the top of my mixer with plastic wrap so the powdered sugar stays contained.
- Add the vanilla, milk, and salt. (start with 1 tsp., if it is too sweet tasting you can add the other 1/2 tsp. salt). Beat on medium until frosting looks light and fluffy.
