I’ve said it before and I’ll say it again: I’m no baker. Seriously, if you’re searching for some beautiful work of culinary art, look away now. However, I’ve got to say that these turned out pretty awesome, aesthetically, for the amount of amateur ability that was put into them. They taste even better.
These cakes are the size of tin cans, which makes them really special and fun to serve. How’d I get them to be that size? Drum roll, please… I made them in tin cans! Really.
I had heard about baking desserts in tuna cans before, so when I wound up with 5 empty tin cans leftover from making chicken corn chowder for my boyfriend (he came down with a cold just a few days before his birthday), I decided that I should also bake his birthday cake in them.
The cans were from the corn I used in the chowder, so I was afraid that the cake would wind up smelling or tasting like corn. After a good scrub, however, the cans were corn-smell free, and they wound up tasting perfectly wonderful.
Really what makes these cakes special isn’t their shape– it’s the taste. Flavorful, slightly bitter dark chocolate meets creamy peanut butter in an explosion of dessert-y goodness. You’ve got some rich, dark chocolate cake; layers of peanut butter frosting; a coating of dark chocolate peanut butter ganache; and some dark chocolate peanut butter cups to top it all off. This was only the third time I have ever even successfully made a cake from scratch, so don’t be intimidated. If I can make these without messing them up, anyone can.
These would be a great treat for someone special on Valentine’s day, by the way. I mean, who wants a cupcake when you can have a mini tower of cake instead?
- 5 empty soup, vegetable, or other tin cans
- Dark chocolate peanut butter cups, chopped, for topping (optional)
- 2 ¼ cups sugar
- 1 ¾ cups all-purpose flour
- ¾ cups unsweetened cocoa powder
- 3 tablespoons Hershey’s Special Dark Cocoa
- 2 teaspoons baking soda
- 1 teaspoon baking powder
- 1 teaspoon kosher salt
- 2 eggs
- 1 cup buttermilk
- 1 cup strong black coffee
- ½ cup vegetable oil
- 2 teaspoons vanilla extract
- 4 tablespoons unsalted butter, softened
- ½ cup peanut butter
- 1 cup powdered sugar
- 2 tablespoons milk
- 10 ounces bittersweet dark chocolate chips
- 1 ¼ cup heavy cream
- 1 teaspoons unsalted butter
- ¼ cup peanut butter
- Preheat the oven to 350 degrees F.
- Remove the paper from the outside of your empty cans and clean them well. Grease and flour the inside of the cans. Set aside.
- In a large bowl, combine sugar, flour, unsweetened cocoa, dark cocoa, baking soda, and baking powder. Whisk the dry ingredients until they are well distributed.
- Add the eggs, coffee, buttermilk, oil, and vanilla to the dry mixture. Using an electric mixer, beat for 2-3 minutes, or until there are no lumps. The batter will be quite thin compared to typical cake batter.
- Pour the batter into the cans, filling each about half-way.
- Bake for about 25-30 minutes, or until a toothpick inserted into the center of the cake comes out clean.
- As you wait for the cakes to bake, make the Peanut Butter Frosting. Using an electric mixer, beat the butter and peanut butter together in a medium sized bowl.
- After the butter and peanut butter are well combined, slowly add the powdered sugar as you continue to beat together the ingredients. Then, add the milk, and beat until the frosting reaches your desired consistency.
- When cakes have finished baking, be sure to let them cool completely. You may then either remove them by popping them out of the can, or if you are having difficulty, use a can opener to open the other side of the can and then push them out. Either way, be careful of sharp edges!
- After you have removed the cakes, you will notice that the top of the cake tower is rounded, like a cupcake or muffin top. Carefully and evenly cut this part off, so you are left with an even cylindrical cake. Then, cut the cake into equal layers. I cut mine into 4 layers. Try to cut them evenly, as uneven layers may cause your cake to tilt.
- To frost in between the layers, pipe frosting around the edge of the top of one layer. Then, pipe another, smaller circle inside of that one. Using a knife, even out all of the frosting to get a smooth layer. You can simply slap on the frosting using a knife instead, if you’d like, but you will likely wind up with a much messier looking cake, as I found out the hard way.
- After you have topped each layer with frosting, re-stack them to assemble your layer cake. Place the tower cakes in the refrigerator as you make the ganache.
- To make the ganache, start by putting the dark chocolate chips into a large, heat-proof mixing bowl.
- Heat a small saucepan on low and add heavy cream, butter, and peanut butter. Stir constantly until the mixture is fully incorporated. Try not to let the mixture come to a boil.
- Pour the hot peanut butter mixture over the chocolate and whisk until all of the chocolate has melted and the ganache is smooth.
- Pour the ganache over each cake, and top with chopped dark chocolate peanut butter cups.
