Our town’s annual school fundraiser bake sale always brings out everyone’s competitive baking spirit. The sign up sheet filled quickly with brownies, cookies, and classic vanilla cupcakes. One of the teachers joked that the chocolate table needed something new this year because it always disappeared first. That little comment stuck in my mind all week while planning what to bring.

⁠

A few days later, a neighbor stopped by with a small basket of fresh blackberries from her garden. The berries were deep purple and slightly tart, and my kids immediately wanted to snack on them before dinner. Instead of letting them vanish in minutes, I decided they deserved a dessert that felt special and worth sharing.

That evening, the kitchen turned into a mini baking workshop. My daughter washed berries, my son lined cupcake tins, and music played while cocoa powder dusted the counter. By the time the cupcakes cooled, the house smelled like chocolate and berries, and the tray was ready for the bake sale table.

Short Description

Dark Chocolate Blackberry Cupcakes combine rich cocoa cupcakes with fresh blackberry frosting for a balanced dessert that is moist, tender, and lightly fruity.

Key Ingredients

For the cupcakes

1 cup dark cocoa powder
1½ cups all purpose flour
1 cup brown sugar
2 large eggs, room temperature
1 cup buttermilk, room temperature
¾ cup hot coffee
1 cup mashed fresh blackberries

For the frosting

½ cup strained blackberry puree
1 cup unsalted butter, softened
3 cups powdered sugar
2 tablespoons heavy cream

Tools Needed

Muffin tin
Cupcake liners
Mixing bowls
Hand mixer
Rubber spatula
Fine mesh strainer

Cooking Instructions

Step 1: Prepare the berries
Mash fresh blackberries gently for the batter, leaving some texture. Puree additional berries and strain through a fine mesh sieve for frosting to remove seeds.

Step 2: Preheat oven and prep pan
Preheat oven to 350°F. Line cupcake pan with paper liners.

Step 3: Mix dry ingredients
In a bowl whisk cocoa powder, flour, and brown sugar until evenly combined.

Step 4: Combine wet ingredients
In another bowl whisk eggs and buttermilk until smooth. Slowly pour in hot coffee while mixing. This step deepens chocolate flavor and creates a smooth batter.

Step 5: Combine batter
Fold dry ingredients into wet mixture just until incorporated. Batter will be thin. Gently fold in mashed blackberries.

Step 6: Fill and bake
Fill liners ¾ full. Bake for 18 to 20 minutes until a toothpick shows moist crumbs. Cool in pan 10 minutes, then transfer to rack.

Step 7: Prepare frosting
Beat softened butter until creamy. Add powdered sugar gradually. Mix in strained blackberry puree and heavy cream until fluffy and pipeable.

Step 8: Decorate cupcakes
Pipe or spread frosting onto cooled cupcakes. Garnish with fresh berries or cocoa powder.
