Hi guys! It’s Alyssa from My Sequined Life back to share a dessert that isn’t for the faint of heart. This fudgy peanut butter brownie cake is a delicious spin on brownies that is full of peanut butter flavor. And the best part is – it can feed a crowd! Just slice and serve.
Now that Valentine’s Day has come and gone, I hope you’ll forgive me for sharing a chocolate dessert. 😉 One of my favorite sweet indulgences is making a batch of brownies, but sometimes even tried and true, classic brownies need jazzing up. Enter this peanut butter brownie cake, which is a take on my fudgy dark chocolate brownie cake. It’s a fudgy brownie recipe that includes melted peanut butter chips in the batter, three types of mix ins, and a deliciously sweet drizzle over top. Instead of being cut into squares, the brownie batter is baked in a 9″ round pan and cut into slices like a cake for an ultra easy way to fancy up dessert.
Now let’s talk about those mix ins. Peanut butter cups (which I chopped into four equal-ish pieces), peanut butter chips, and semisweet chocolate chips were added to the batter here, but you can certainly do your own thing here. You can add all peanut butter chips or all chocolate chips, or do more or less of the chopped peanut butter cup pieces. I don’t think you can go wrong any way you choose.
A little presentation tip I like to do when it comes to baked goods is to lightly press a few of the mix ins into the top of whatever it is I’m making so they’re visible in the finished product. Visible under that chocolate and peanut butter drizzle, of course. 🙂
I just did a simple drizzle on top of this brownie cake, but if you’re making it for a special occasion, go to town on your decorations! Add festive sprinkles for a colorful touch, or pipe ‘happy birthday’ in frosting if this cake will be gracing a birthday dessert table for that chocolate + peanut butter lover in your life.
How Long Will Brownies Keep?
Brownies will keep 3-4 days at room temperature.
They should be tightly covered.
Can Brownies Be Made Without Eggs?
Applesauce and bananas make good substitutes for eggs in baking.
For a densely textured brownie, replace one egg with a half of a small banana that has been well mashed with a fork.
Are Brownies Supposed to Be Soft?
Brownies are meant to be crisp on the outside and soft and fudgy on the inside.
If your brownies are too soft, the problem is likely due to improper cooking times or temperatures.

For the cake:
- 1/2 cup unsalted butter, 8 tbsp, cut into small pieces
- 2/3 cup semisweet chocolate chips, plus 1/4 cup
- 1/3 cup peanut butter chips, plus 1/4 cup
- 3/4 cup granulated sugar
- 2 eggs
- 2 tsp vanilla extract
- 1/2 cup all-purpose flour
- Pinch of salt
- 1/2 cup Reese's peanut butter cups, about 10 PB cups, chopped
For the drizzle:
- 1/4 cup semisweet chocolate chips
- 1/4 cup peanut butter chips
- Heat oven to 350 degrees F and grease a 9" round cake pan.
- Set pan aside.
- Add butter, 2/3 cup of semisweet chocolate chips and 1/3 cup of peanut butter chips to a microwave-safe bowl and heat in 20-second intervals on half-power in the microwave, scraping down the sides and stirring after each interval until the mixture is smooth and melted. You may also do this step on the stove with a double boiler if you prefer.
- Once melted, add butter mixture to a mixing bowl and add sugar.
- Whisk until sugar is thoroughly combined.
- Add eggs and vanilla extract and whisk again until all mixed in.
- Add flour and salt and stir until the dry ingredients are just mixed in. The batter will be fairly thick and smooth.
- Stir in the chopped Reese's peanut butter cups, 1/4 cup of semisweet chocolate chips and 1/4 cup of peanut butter chips.
- Pour batter into the prepared cake pan and smooth the top with a spoon so that it's level.
- Press additional chips and/or chopped Reese's peanut butter cups into the top if you like.
- Bake for 22-28 minutes, or until the top has set, the edges have begun to brown, and a tester inserted into the center comes out clean.
- Remove from oven and let brownie cake cool completely in the pan before slicing.
- To decorate, melt semisweet and peanut butter chips in the microwave and transfer to two separate piping bags.
- Pipe zigzags or whatever design you please over top.
- Once cooled, decorated, and ready to slice, run a knife around the outside edge of the brownie cake to loosen it, and cut into slices.

So you used the small reeces pieces? Because that’s what I got. can’t wait to make this!!
Hi Shar, I used the small-sized peanut butter cups (the ones with the wrapper) and cut them into smaller chunks, but Reese’s Pieces will work great too!

I only just discovered how much I love Reeses Pieces as here in Australia they are pretty hard to get your hands on. I definitely need to make this brownie cake, it looks amazing.
