This Cherry Dr Pepper Cake is one of those recipes that immediately transports me back to loud family gatherings and sun-warmed backyard tables. I first made this cake during a summer block party when a friend challenged me to bring something different: something chocolate, but with a playful, fizzy twist. Using a chocolate fudge mix plus a can of cherry Dr Pepper felt a little daring, but the result was an irresistibly moist, tender crumb studded with bright maraschino cherries and finished with a silky, pink-tinted buttercream that tasted faintly of the soda's cherry notes. It quickly became a crowd favorite—kids loved the sweetness and grown-ups appreciated the nostalgic soda flavor peeking through the chocolate.

What I love most about this sheet cake is how effortless it is to pull together yet how special it feels on the table. It uses pantry staples and a single jar of cherries to create layers of flavor: deep chocolate from the cake mix, a subtle cherry lift from the Dr Pepper, and a glossy, cherry-scented frosting that ties everything together. I often double the recipe for larger gatherings, and the leftovers (if there are any) keep well for several days, making it an ideal simple celebration dessert. This version is adapted to be made entirely without additional eggs or oil, relying on the soda for lift and moisture—an easy shortcut that yields excellent texture every time.

Ingredients

• 15.25 ounce box super moist chocolate fudge cake mix: I use a well-known mix such as Duncan Hines or Betty Crocker Super Moist Chocolate Fudge for consistent texture; it provides the chocolate base and structure without extra measuring. Look for the 15.25 ounce size on the shelf.
• 12 ounces cherry Dr Pepper: Use a can at room temperature for better carbonation integration. The cherry Dr Pepper adds sweetness and a subtle fruit acidity that keeps the crumb tender.
• 18 ounces maraschino cherries, divided: A standard jar drained; reserve about 6 tablespoons of the cherry juice for the frosting. Remove stems and use 24 cherries chopped for the batter and the remainder whole for garnish.
• 1 cup salted butter (2 sticks): At room temperature for easy creaming; salted butter balances the sweetness of the powdered sugar in the frosting.
• 7 cups powdered sugar: Sifted if lumpy; adding it a cup at a time into the creamed butter helps create a smooth, pipeable frosting.

Instructions

Prepare the pan and oven: Preheat the oven to 350 degrees F. Spray a 9x13x2 baking pan with nonstick cooking spray or line with parchment, leaving an overhang for easy removal. Position the oven rack in the center to ensure even baking. Mix the batter: In a large bowl combine the dry cake mix and the 12 ounce can of cherry Dr Pepper. Whisk gently until just combined and smooth—overmixing can activate too much gluten in the mix and create a tougher crumb. The batter will be thinner than a traditional cake batter because the soda thins the mix, which helps produce a super moist sheet cake. Prepare and fold in cherries: Remove 24 cherries from the jar, discard stems, and quarter them. Reserve the remaining cherries for garnish. Fold the quartered cherries into the batter with a rubber spatula until distributed evenly. If the cherries are particularly syrupy, pat them dry on paper towels first to avoid adding excess liquid. Bake: Pour the batter into the prepared pan and smooth the surface with an offset spatula. Bake on the center rack for approximately 30 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs. Ovens vary: if the cake is still very jiggly at 30 minutes, give it another 3 to 5 minutes and retest. Cool: Allow the cake to cool in the pan on a wire rack for 20 to 30 minutes. Cooling slightly makes spreading the frosting easier; if you frost while very warm the frosting will melt and run. For a firmer cake surface, cool completely. Make the frosting: In a stand mixer fitted with the whisk attachment, beat 1 cup (2 sticks) room-temperature salted butter until light and fluffy, about 3 minutes. Add the 7 cups powdered sugar, 1 cup at a time, beating on low between additions until fully incorporated. Add 3 ounces (6 tablespoons) of the reserved maraschino cherry juice and increase speed to medium-high; beat until the frosting is pale and airy, about 2 to 3 minutes. Adjust consistency with a teaspoon of milk or extra powdered sugar if needed. Frost and garnish: Spread the frosting evenly over the cooled cake using an offset spatula. Garnish with the remaining whole maraschino cherries, spacing them evenly. Chill briefly to set the frosting if you want cleaner slices.

Storage Tips

Store the cake tightly covered at room temperature for up to 2 days. Because the frosting contains butter and cherry juice, refrigeration extends shelf life to 5 days; bring slices to room temperature before serving for best texture. For longer storage, slice portions and wrap each piece tightly in plastic wrap followed by foil and freeze for up to 3 months. To reheat frozen slices, thaw overnight in the refrigerator and then sit at room temperature for 30 to 60 minutes or warm gently in a 150 degrees F oven for 10 minutes if you prefer a slightly softened frosting.

Ingredient Substitutions

If you cannot find cherry Dr Pepper, substitute with a similar cherry-flavored cola or flat cherry soda at room temperature; flat soda will reduce airiness but maintain flavor. For a less sweet frosting, swap 1 cup of powdered sugar for 1 cup of sifted confectioners sugar with a tablespoon of cream cheese—this creates a tangier finish but requires refrigeration. For a dairy-free version, replace the butter in the frosting with a vegan butter alternative measured 1:1 and chill the frosting slightly before spreading to help it set.

Serving Suggestions

This sheet cake is wonderful on its own with a cup of coffee or cut into small squares for a dessert buffet. For a celebratory presentation, serve with a dollop of lightly whipped cream and a drizzle of warmed cherry preserves. Pair with vanilla ice cream for contrast or offer small espresso shots to balance out the sweetness. Garnish with chopped toasted pecans for texture or shave dark chocolate over the top for an elegant finish.

Cultural Background

Soda-based cakes have a fun place in American home baking, tracing back to times when carbonated beverages were used to simplify recipes and add moisture. The idea of using cola or soda in boxed mix combinations became popular mid-20th century as convenience mixes grew. This cake blends that tradition with a retro cherry soda flavor, nodding to classic soda fountain flavors while using modern pantry shortcuts to achieve a soft, tender crumb without extra fat or eggs.

Seasonal Adaptations

In summer, use bright red maraschino cherries and serve chilled. For a winter twist, fold in a teaspoon of cinnamon or replace the cherry juice in the frosting with a splash of bourbon for depth. For Valentine-themed gatherings, color the frosting a pale pink with a few drops of natural red food coloring or beet powder and top with heart-shaped sprinkles.

Meal Prep Tips

Make the cake up to 24 hours ahead and store unfrosted, tightly wrapped at room temperature. Prepare the frosting the morning of serving and spread on the cooled cake an hour before guests arrive. If packing for transport to a potluck, freeze the cake for 20 minutes after frosting to firm it up and reduce movement, then wrap gently for travel.

At the end of the day, this cake is about approachable celebration—a simple method yielding festive results. Whether you need a quick dessert for a picnic or a nostalgic showstopper, this Cherry Dr Pepper Cake is reliably delicious and easy to make your own.
