This Cherry Dr. Pepper cake has been a celebration staple in my family for as long as I can remember. I first tasted a version of it at a summer picnic when a neighbor brought a glossy chocolate sheet cake dotted with bright cherries; the soda in the batter gave it a tender crumb and a faint, caramel-like lift that set it apart from ordinary boxed cakes. I recreated that memory in my kitchen, swapping in a cherry-flavored Dr. Pepper and a jar of maraschino cherries, and the result became an instant favorite. The cake is quick to make, forgiving in technique, and yields that nostalgic combination of sweet cherry and deep chocolate that makes people smile at the first bite.

What makes this cake truly special is the way the soda lightens the dry cake mix while adding subtle cola-cherry notes that complement the fresh-sweetness of the cherries. The frosting — a simple buttercream sweetened and fragrant with maraschino cherry juice — sets up firm enough to slice cleanly after chilling, and the chocolate shavings on top add texture and an elegant finish. It’s the kind of dessert you’ll bring to a potluck and be asked for the recipe, and the kind you’ll bake when you want something that feels both throwback and polished.

Ingredients

• Chocolate cake mix (dry only): Use your favorite boxed chocolate mix (15.25–16.5 ounce box). A brand like Duncan Hines or Pillsbury gives consistent texture; we’re only using the dry mix and replacing the required liquids with soda for tenderness and flavor.
• Dr. Pepper Cherry: 1 1/2 cups (12 fl oz). The cherry-flavored soda adds moisture and a subtle cola-cherry note—choose the labeled Cherry Dr. Pepper for the most pronounced fruit character.
• Maraschino cherries: 1 (10–12 ounce) jar, drained. Remove 24 cherries and set them aside whole for decoration; halve the remainder and fold into the batter to distribute pops of cherry in every slice.
• Unsalted butter: 1 cup (2 sticks / 8 tablespoons), softened to room temperature for smooth frosting. Use high-quality butter like Plugrá or Kerrygold for better flavor.
• Powdered sugar: 3 cups for the frosting, plus up to 2 additional cups if you need to thicken the icing to a spreadable, stable consistency.
• Chocolate shavings: 1 container (about 1–2 ounces) of shavings for garnish; you can find decorative chocolate curls or shavings at craft stores like Hobby Lobby or the baking aisle of specialty shops.

Instructions

Preheat and prepare: Preheat your oven to 350°F. Spray a 9x13-inch baking dish liberally with nonstick spray and set aside. Preheating ensures even rise and predictable bake time; a well-sprayed pan helps the sheet cake release cleanly. Mix the batter: In a stand mixer fitted with the paddle attachment, combine the dry cake mix with 1 1/2 cups (12 fl oz) Cherry Dr. Pepper. Mix on low to combine, then increase to medium for 30–45 seconds until smooth—avoid overmixing. The soda replaces the usual wet ingredients and gives the batter a thin, pourable consistency; if it seems too thin, a brief rest will let air bubbles settle. Prepare the cherries: Drain the jar of maraschino cherries, reserving the syrup (you’ll use a tablespoon or two for the frosting). Remove 24 whole cherries for garnish and halve the remainder. Fold the halved cherries into the batter gently so they don’t sink immediately to the bottom; chopping them slightly helps them stay suspended. Bake: Pour the batter into the prepared 9x13 baking dish and smooth the top with an offset spatula. Bake at 350°F for about 30 minutes, or until a toothpick inserted into the center comes out clean. Check at 25 minutes: ovens vary, and you want the cake just set with a slightly springy center to avoid drying. Cool completely: Allow the cake to cool in the pan on a wire rack until it reaches room temperature. Cooling fully before frosting is essential—warm cake will cause buttercream to melt and weep, and the final texture will be gummy. Make the cherry buttercream: In a clean stand mixer bowl, beat 1 cup (2 sticks) softened unsalted butter on medium-high until light and pale, about 2 minutes. Gradually add 3 cups powdered sugar on low, then add 2–3 tablespoons reserved maraschino cherry juice and continue beating until light and fluffy. If the frosting is too thin to hold peaks or to spread cleanly, add powdered sugar 1 cup at a time (up to 2 additional cups) until the desired stiffness is reached. Frost and decorate: Use an angled spatula to scoop the buttercream onto the cooled cake and smooth evenly. Immediately sprinkle chocolate shavings across the top and arrange the reserved whole cherries decoratively. A light, even pressure with the spatula prevents air pockets beneath the frosting. Chill to set: Place the frosted cake in the refrigerator for at least 1 hour to allow the buttercream to firm up. Chilling makes cleaner slices and intensifies flavors; remove from the fridge 15 minutes before serving for the best mouthfeel.

Storage Tips

Store leftovers in an airtight container or cover the pan tightly with plastic wrap to prevent the frosting from picking up refrigerator odors. Keep refrigerated; the cake will retain optimal texture for 2–3 days. For longer storage, slice the unfrosted cake into portions, wrap them individually in plastic wrap and foil, and freeze for up to 3 months. Thaw overnight in the refrigerator and frost fresh, or let come to room temperature before serving if already frosted. Avoid leaving the frosted cake at room temperature for more than two hours because the buttercream will soften and may become greasy.

Ingredient Substitutions

If you need to avoid gluten, use a certified gluten-free chocolate cake mix and ensure other ingredients are labeled gluten-free; texture may be slightly different. For a dairy-free version, substitute vegan butter and use a dairy-free boxed mix designed to work with oil or water—note the frosting will behave differently and may require powdered sugar adjustments. Want a less sweet frosting? Replace a cup of powdered sugar with 2–3 tablespoons of cocoa powder and increase cherry juice slightly for balance. If you don’t have cherry soda, a mix of cola and a splash of cherry syrup or cherry juice can approximate the flavor.

Serving Suggestions

Serve slices with a dollop of lightly whipped cream or a scoop of vanilla bean ice cream to balance the sweetness. For a brunch or tea event, cut the cake into smaller squares and serve on doilies with extra cherries on the side. Garnish with fresh mint leaves for a color contrast and subtle freshness. This cake also pairs well with bold coffee or a black tea that can cut through the sweetness. For a festive presentation, create a border of chocolate shavings and place the reserved cherries in a neat row down the center.

Cultural Background

Soda-based cakes have a long place in American home baking, with variations like Coca-Cola cake and root beer cupcakes appearing in mid-20th-century cookbooks. Using carbonated beverages in boxed mixes was a popular way to create moistness and introduce regional flavors without complex techniques. The Cherry Dr. Pepper iteration is a modern twist on that tradition—combining the nostalgic comfort of soda-bottle confections with the bright, decorative look of maraschino cherries. It’s a dessert that nods to social baking traditions while remaining accessible to any home cook.

Seasonal Adaptations

In summer, serve chilled with fresh seasonal cherries folded into the batter in place of maraschinos for a less sweet, brighter fruit note. For winter holidays, substitute a splash of cherry liqueur into the frosting and top with chopped toasted pecans for warmth. On Valentine’s Day, double the cherries and pipe rosettes of buttercream for a romantic look. Small adjustments—like swapping soda for a diet version or adding espresso powder to intensify chocolate—let you tailor this dessert to the season and occasion.

Meal Prep Tips

To meal prep slices for grab-and-go treats, cut the chilled cake into individual portions and store them in airtight containers with parchment between layers to prevent sticking. If frosting ahead, chill the cake until firm, then wrap securely and refrigerate for up to 3 days. For freezer-friendly prep, freeze unfrosted slabs and defrost before frosting; this yields the freshest texture. When transporting, keep the cake chilled in a cooler to protect the buttercream during travel.

This Cherry Dr. Pepper cake blends simplicity and nostalgia in a way that’s both approachable and memorable. Give it a try at your next gathering—little touches like chocolate shavings and arranged cherries make it feel special, and the flavors will likely become part of your family memories too. Enjoy!
