I’m kind of obsessed with soda cakes– you know the cake hack where you add a bottle of soda and literally nothing else to boxed cake mix and somehow get a perfect cake every time?! My brain can’t comprehend how that works, but I think it’s amazing. This Dr Pepper cake follows a similar principle, but the cake is homemade! I combined a rich, chocolatey sheet cake with Dr Pepper soda (I added it to the frosting, too!) to create a crave-able chocolate cake that’s just what the doctor ordered!

I may not know what the 23 flavors in Dr Pepper are, but I love them nonetheless. They taste so good in this chocolate cake, and the carbonation makes the cake so light and fluffy! Making it sheet cake-style was a good call on my part. It’s so unfussy and easy to whip together whenever the craving strikes. My kids love seeing me use their favorite soda to make cake!
What’s in This Dr Pepper Cake Recipe?
- Flour: All-purpose flour gives this cake structure.
- Cocoa Powder: Unsweetened cocoa powder adds rich chocolate flavor to both the cake and the frosting.
- Baking Soda: Helps the cake rise to become light and fluffy.
- Salt: Kosher salt enhances the chocolate flavor of the cake.
- Oil: Vegetable oil adds moisture to this cake.
- Sugar: A combination of granulated and brown sugar sweetens the cake and enhances the molasses flavor contributed by the soda, while powdered sugar sweetens the frosting without making it gritty.
- Eggs: Give this cake additional structure and moisture.
- Vanilla Extract: Enhances the sweet flavor of this cake.
- Dr Pepper Soda: While this classic soda doesn’t contribute an overpowering taste to the cake, it does help keep it super moist and fluffy thanks to its carbonation. I added some to the frosting so you do get a touch more of those 23 flavors!
- Greek Yogurt: My secret weapon for a super rich and moist cake. It adds just a hint of tanginess, too, that helps cut the sweetness of this cake, and the acid makes it tender. Sour cream also works well.
- Butter: Unsalted butter forms the base of the rich frosting.

Tips for Success
- Make sure your eggs and dairy are at room temperature so the batter combines evenly and doesn’t end up chunky.
- If you don’t have access to Dr Pepper, any kind of dark cola or root beer will work.
- I have not tried this recipe with diet soda, so I cannot comment on whether or not that will work.
- Once you add the Dr Pepper, don’t overmix the batter or you will knock out all the air bubbles you just added, defeating the purpose of adding the soda.
- To make cupcakes instead, fill lined cupcake tins ⅔ full and bake for about 15 minutes.
- Insert a toothpick into the center of the cake to check for doneness. The toothpick should come out clean or with a few moist crumbs.
How to Store
Store leftover Dr Pepper cake tightly covered with plastic wrap at room temperature for up to 2 days or in the refrigerator for up to 4 days. Freeze individual slices tightly wrapped in 2 layers of plastic wrap and 1 layer of aluminum foil for up to 1 month, and let thaw overnight in the refrigerator before enjoying.

I made this cake because my Besty all she drinks is Dr Pepper. So my daughter is moving so I thought I would kill two birds with one cake. She had workers all over. I just made it out with one piece, my friend took some the worker he ate two and I gave him a piece to take home. When I got home, I gave my neighbor a piece cause I just moved in a new place. The rave on the RAVE on the cake was”IT’S THE BEST CAKE I HAVE EVER TASTED” I was ask to make it again . Thanks for the recipe 🥰
Back in the 60’s we made Dr Pepper cake. We used butter in the cake batter and added mini marshmallows before we baked it. They floated up to the top and were a little crispy. I’ve got to try this recipe.
