Ingredients for Dr. Pepper Cake

For the Cake

• ½ cup prunes, roughly chopped
• ½ cup dried cherries, roughly chopped
• 1 cup Dr. Pepper soda
• 1 cup (2 sticks / 226g) unsalted butter, room temperature
• ¼ cup cocoa powder
• ½ cup boiling water
• ½ cup buttermilk
• 3 large eggs, room temperature
• 1 teaspoon baking soda
• 1½ teaspoons vanilla extract
• 2 cups (256g) all-purpose flour
• 1⅓ cups (267g) granulated sugar
• ½ teaspoon nutmeg
• ½ teaspoon ground ginger
• ½ teaspoon allspice

For the Frosting

• 4 cups Dr. Pepper soda
• 1½ cups (3 sticks / 339g) unsalted butter
• 1 teaspoon ground ginger
• 2½ cups (312g) confectioners’ sugar
• 1 teaspoon vanilla extract

Step 1: Prepare the Fruit

Place the chopped prunes, dried cherries, and 1 cup of Dr. Pepper into a saucepan. Bring to a gentle simmer and cook for about 10 minutes until the fruit softens and absorbs some of the soda. Remove from the heat and let cool.

Step 2: Prepare the Oven and Pan

Preheat your oven to 350°F (175°C). Grease and lightly flour a 9×13-inch baking pan or line it with parchment paper for easier removal.

Step 3: Make the Chocolate Mixture

In a medium saucepan, melt the butter over medium heat. Stir in the cocoa powder, then slowly whisk in the boiling water until smooth. Remove from the heat and allow the mixture to cool for several minutes.

Step 4: Mix the Wet Ingredients

In a large mixing bowl, whisk together the buttermilk, eggs, vanilla extract, and baking soda. Stir in the cooled cocoa mixture and the softened fruit mixture until well combined.

Step 5: Combine the Dry Ingredients

In another bowl, whisk together the flour, sugar, nutmeg, ginger, and allspice until evenly blended.

Step 6: Finish the Batter

Gradually fold the dry ingredients into the wet ingredients. Mix only until no streaks of flour remain. Pour the batter into the prepared baking pan and smooth the top with a spatula.

Step 7: Bake

Bake for 35 to 40 minutes, or until a toothpick inserted into the center comes out with only a few moist crumbs attached. Let the cake cool completely on a wire rack before frosting.

Step 8: Make the Dr. Pepper Frosting

Pour 4 cups of Dr. Pepper into a saucepan and simmer until reduced to about ½ cup. Let it cool slightly. Beat the butter until creamy, then gradually mix in the reduced soda, ground ginger, vanilla, and confectioners’ sugar until smooth and fluffy.

Step 9: Frost and Serve

Spread the frosting evenly over the cooled cake. Slice into squares and serve at room temperature for the richest flavor.

Notes

• The prunes become almost undetectable while adding incredible moisture.
• Reducing the soda intensifies its signature flavor in the frosting.
• This cake tastes even better the following day.
• Add chocolate shavings or cherries for an elegant garnish.
• Store leftovers tightly covered to maintain freshness.

Watch Out for These Mistakes While Cooking

• Skipping the reduction step for the frosting can result in a thin consistency.
• Overbaking will dry out the cake.
• Adding hot cocoa mixture directly to the eggs may scramble them.
• Overmixing the batter can make the cake dense.
• Using cold ingredients may prevent the batter from mixing evenly.
• Frosting the cake before it’s completely cool will cause the frosting to melt.
• Measuring flour incorrectly can create a dry texture.
• Reducing the soda too quickly over high heat may burn the syrup.

Frequently Asked Questions

Can I use Diet Dr. Pepper instead of regular Dr. Pepper?

It’s best to use regular Dr. Pepper. The sugar in the soda contributes to both the cake’s flavor and the frosting’s consistency, while diet versions may alter the final texture.

Do the prunes make the cake taste like prunes?

Not at all. The prunes blend seamlessly into the batter, adding moisture and richness without leaving a noticeable prune flavor.

Can I make this cake ahead of time?

Yes! In fact, Dr. Pepper Cake often tastes even better the next day as the flavors have more time to develop.

Can I freeze the cake?

Absolutely. Wrap the cooled cake or individual slices tightly in plastic wrap and aluminum foil before freezing for up to 3 months. Thaw overnight in the refrigerator.

Can I make cupcakes instead of a sheet cake?

Yes. Divide the batter into lined muffin tins and bake for about 18–22 minutes, checking for doneness with a toothpick.

Why is my frosting too thin?

The Dr. Pepper likely wasn’t reduced enough, or it was still warm when mixed with the butter. Let the reduction cool and reduce it to a thick syrup before making the frosting.

Can I substitute the dried cherries?

Yes. Dried cranberries, raisins, or chopped dried figs work well while maintaining the cake’s moist texture.

What is the best way to store leftovers?

Store the cake in an airtight container in the refrigerator for up to 5 days. Allow it to sit at room temperature for 20–30 minutes before serving for the best flavor and texture.
