Chocolate Peanut Butter Cake
It was Pranas’ birthday on Saturday. He is 24. Yay! Happy birthday!
So of course, I made a cake. I gave him several options, and this is the one he chose. Goooood choice.
This cake is so decadent it’s almost ridiculous. No, it definitely IS ridiculous. It took me three sittings over the course of 24 hours to finish my first (thin!) slice.
But ohhh man, is it good. This is definitely the best cake I’ve ever made—if not the best cake I’ve ever tasted. It takes like a cakey-delicious peanut butter cup. If you love chocolate and peanut butter (and if you don’t, let’s be honest—what’s wrong with you?!), you may soon need gastric bypass surgery because you will LOVE this cake.
All I can say is, keep your slices thin and your glasses full of milk. This recipe is from Sky High: Irresistible Triple-Layer Cakes via Smitten Kitchen, one of my favorite food blogs.

Sour Cream-Chocolate Cake with Peanut Butter Frosting and Chocolate-Peanut Butter Glaze
Makes an 8-inch triple-layer cake; serves 12 to 16 (my cake will have served a lot more by the time it’s all eaten)
2 cups all-purpose flour
2 1/2 cups sugar
3/4 cup unsweetened cocoa powder, preferably Dutch process
2 teaspoons baking soda
1 teaspoon salt
1 cup neutral vegetable oil, such as canola, soybean or vegetable blend
1 cup sour cream
1 1/2 cups water
2 tablespoons distilled white vinegar
1 teaspoon vanilla extract
2 eggs
1. Preheat the oven to 350 degrees F. Butter the bottoms and sides of three 8-inch round cakepans. Line the bottom of each pan with a round of parchment or waxed paper and butter the paper.
2. Sift the flour, sugar, cocoa powder, baking soda, and salt into a large bowl. Whisk to combine them well. Add the oil and sour cream and whisk to blend. Gradually beat in the water. Blend in the vinegar and vanilla. Whisk in the eggs and beat until well blended. Scrape down the sides of the bowl and be sure the batter is well mixed. Divide among the 3 prepared cake pans.
3. Bake for 30 to 35 minutes, or until a cake tester or wooden toothpick inserted in the center comes out almost clean. Let cool in the pans for about 20 minutes. Invert onto wire racks, carefully peel off the paper liners, and let cool completely. (Smitten Kitchen suggested freezing the cakes for 30ish minutes before frosting and I second that emotion. They’ll be much easier to frost once they firm up a little)
4. To frost the cake, place one layer, flat side up, on a cake stand or large serving plate. Spread 2/3 cup cup of the Peanut Butter Frosting evenly over the top. Repeat with the next layer. Place the last layer on top and frost the top and sides of the cake with the remaining frosting. (Another SK suggestion was to refrigerate after frosting, then refrigerate again after glazing. Also very wise.)
5. To decorate with the Chocolate–Peanut Butter Glaze, put the cake plate on a large baking sheet to catch any drips. Simply pour the glaze over the top of the cake, and using an offset spatula, spread it evenly over the top just to the edges so that it runs down the sides of the cake in long drips. Refrigerate, uncovered, for at least 30 minutes to allow the glaze and frosting to set completely. Remove about 1 hour before serving (totally optional—I happen to think it’s really delicious when it’s cold and it somehow cuts the richness a little).
Peanut Butter Frosting
Makes about 5 cups
10 ounces cream cheese, at room temperature
1 stick (4 ounces) unsalted butter, at room temperature
5 cups confectioners’ sugar, sifted (Note: I only used 4 cups and it was PLENTY sugary and a perfect consistency. Test for taste and consistency as you go so you don’t overdo the sugar)
2/3 cup smooth peanut butter, preferably a commercial brand (because oil doesn’t separate out)
1. In a large bowl with an electric mixer, beat the cream cheese and butter until light and fluffy. Gradually add the confectioners’ sugar 1 cup at a time, mixing thoroughly after each addition and scraping down the sides of the bowl often. Continue to beat on medium speed until light and fluffy, 3 to 4 minutes.
2. Add the peanut butter and beat until thoroughly blended.
Chocolate-Peanut Butter Glaze
Makes about 1 1/2 cups
8 ounces seimsweet chocolate, coarsely chopped
3 tablespoons smooth peanut butter
2 tablespoons light corn syrup
1/2 cup half-and-half
1. In the top of d double boiler or in a bowl set over simmering water, combine the chocolate, peanut butter, and corn syrup. Cook, whisking often, until the chocolate is melted and the mixture is smooth.
2. Remove from the heat and whisk in the half-and-half, beating until smooth. Use while still warm.

Your cast of characters. Ignore the baking powder. It’s not in the recipe and therefore won’t be appearing in the show. Somehow he snuck into this photo though.

So, the first thing is to combine all of your dry ingredients. That’s your flour, sugar, cocoa powder, baking soda, and salt. I kind of hate sifting things, and I don’t own an adequate sifter, so I whisk everything. Have you noticed? It doesn’t get ALL the lumps out, but it works. The rest of the little lumps will work themselves out.

Now, dump in your oil and sour cream. I definitely didn’t do anything to try to healthify this recipe. I thought, first of all, it’s not MY birthday, and second of all, if you’re gonna go for it—go for it. Right? Right?! Whisk these together…

…until your whisk becomes clumpy and unusable and you resort to your electric mixer.

Slowly pour in the water as the mixer goes. And I do mean slow—it’s quite a bit of water and you may make a mess of yourself if you dump it in all at once.

Now add your vinegar and vanilla.

And your eggs. And then mix until everything is blended. Then pour your batter evenly into three prepared cake pans (I put parchment rounds in the bottom of each pan and sprayed with baking spray and the cakes turned out beautifully). I don’t have any pictures of this part because all of them happened to be extremely unflattering photos of me. So too bad, you won’t be seeing them. Ha! Now bake according to the recipe. Mine took about 37 minutes rather than 35.

I did not let my cakes cool in the pans for 20 minutes. I turned them out immediately. I don’t know why, I just did. I was in the moment. Look at how pretty they are! But anyway, I put them on wire cooling racks and let them cool for about 30 minutes before I started the frosting.

Now for the frosting. This is super easy and arguably the best part of this cake. First, cream your butter and cream cheese together.

Start adding your confectioners’ sugar about a cup at a time…

…until you get a good taste and consistency. As I mentioned above, I only used four cups of powdered sugar. I probably could have used even less. Five cups is a LOT and trust me, the cake is PLENTY sweet…it could stand a little less sugar. So just play it by ear.

Plop in your peanut butter and mix away until just blended.

Um…let me collect myself for a moment. This frosting will make you re-assess your life. Oh lord.
Now frost! Pretty self-explanatory.


I don’t know what happened to the big “Ta-da!” picture of the frosted cake here, but it’s ok. I guess I don’t have one. It’s pretty though. But we still have glaze to add!
At this point, I stopped taking pictures. I had to take a shower and Pranas’ friends were arriving and yadda yadda yadda, I had to throw the glaze together in approximately 4 seconds. And it was really easy! You can do it in a double boiler or you can be super ghetto like me and do it in the microwave. I just melted the chocolate (stirring every 30 seconds) and stirred everything else in. Super easy.
Then, I poured the glaze on top of the cake and let it drip down the sides. I stuck it back in the fridge until it was time to serve. And..

Voila!
Let’s have some more, shall we?



Haha, look at all the crumbs everywhere. Classy!
Anyway. This cake. I can’t even…it’s amazing. It was a big hit. Go make it for your next special occasion. Or maybe just in honor of Tuesday. Enjoy!
