This Chocolate Peanut Butter Bundt Cake has a tunnel of creamy peanut butter hiding inside our moist chocolate cake. It all gets topped off with a sweet peanut butter glaze and a rich dark chocolate glaze!
You might have noticed that I have a bit of a thing for that chocolate peanut butter combination.
Decadent In The Best Way
Look, I’m not going to pretend this is health food. This is the kind of cake you make when you need chocolate and peanut butter to solve all your problems. And honestly? It works every single time.
I grew up eating Reese’s every chance I could get, then graduated to making my own chocolate peanut butter treats like these chocolate peanut butter no bake cookies, our famous peanut butter lasagna, and these chocolate peanut butter cookies. This bundt cake is basically all of that rolled into one impressive-looking dessert that’s surprisingly easy to pull off.
The hidden peanut butter tunnel gets oohs and ahhs every time someone sneaks a peek at the cake. Seriously delightful.
3 Reasons You’ll Love This Recipe:
- It looks fancy but isn’t fussy. Bundt cakes are naturally gorgeous – no fancy decorating skills required. Just pour on the glaze and watch people think you’re some kind of baking wizard.
- The peanut butter filling is the real star. Sure, the chocolate cake is rich and moist, but that creamy peanut butter tunnel hiding inside? That’s what gets people talking.
- Two glazes are better than one. We’re not messing around here – this cake gets both chocolate AND peanut butter glaze because more is definitely more when it comes to this combination.
Key Ingredient Notes:
Sour cream – This is what makes the cake incredibly moist and tender. 0% fat Greek yogurt would also work well here.
Peanut butter – Stick with regular creamy brands like Jif or Skippy for both the filling and glaze. Natural peanut butter is too oily and won’t give you the right texture.
Butter (partially melted) – Microwave for 30-45 seconds until very soft but not fully liquid. This creates the perfect texture for easy mixing.
Room temperature ingredients – Your eggs, milk, sour cream, and cream cheese should all be at room temperature. They’ll mix together much easier and create a smoother batter.
Cocoa powder – Natural (unsweetened) cocoa powder gives the best chocolate flavor. Dutch-processed cocoa is not recommended here, since it will react with the baking soda and potentially cause a soapy or metallic taste.
Dark chocolate chips – We like dark chocolate in the glaze, but milk or semi-sweet will work here if you like it sweeter.
Prep Your Pan:
Here’s where most people mess up – properly greasing your bundt pan is absolutely essential.
There are 3 methods for preparing your bundt pan:
- Generously butter every single nook and cranny and then dust with flour (for white or yellow cakes) or cocoa powder (for chocolate cakes. Don’t forget the center tube!
- Use a baking spray designed for baking, such as Baker’s Joy. (The easiest method, but the least effective for bundt cakes in my experience.)
- Make your own ‘cake goop’ by mixing equal parts vegetable oil or shortening and flour. Brush this mix into your pan. This is my preferred method!
Step by Step:
Prepare the chocolate cake batter by creaming the butter and sugar and then mixing in the remaining wet and dry ingredients.
Use a hand mixer to whip the cream cheese and peanut butter together in a medium mixing bowl. Add the sugar and flour and beat until smooth and creamy.
Add half of the chocolate cake batter to the pan and spread the peanut butter filling over the top. Pour the rest of the cake batter over that and smooth flat. Bake for 45 minutes and allow to cool for 15 minutes in the pan before removing to a plate to finish cooling for 1 hour.
Drizzle the peanut butter and chocolate glazes over the chocolate Bundt cake and let set for 15 minutes before slicing and serving!
Helpful Tip!
You can pour the glaze on however you like! You could alternate them in patterns or just pour one on and then pour the other over the top. It really doesn’t matter how you glaze the cake as long as you like it!
My Favorite Bundt Pan!
A quality bundt pan is essential! This one is non-stick, budget friendly, and gets used often in my home.
Storage and Make-Ahead Tips
Room temperature storage: This cake stays moist and delicious covered on the counter for up to 3 days.
Refrigerator storage: You can refrigerate it for up to 5 days, but let it come to room temperature before serving for the best texture.
Freezing: Wrap the unfrosted cake tightly and freeze for up to 3 months. Thaw completely before glazing. You can also freeze glazed slices individually for grab-and-go treats, though the glaze doesn’t hold up the best.
Make-ahead for parties: Bake the cake up to 2 days ahead and store covered. Add the glazes the day you’re serving for the prettiest presentation.
FAQs:
If you are looking to experiment with different glaze flavors, caramel is a must try for this Bundt cake. Caramel pairs perfectly with both peanut butter and chocolate. A simple vanilla glaze made with powdered sugar and milk would also be delicious.
Sounds like an easy hack, but cake mix batter is so thin that the peanut butter tunnel will likely sink to the bottom of the cake.
