Blackberry chocolate cupcakes are that perfect mix of tangy fruit and deep cocoa that wins over a crowd at any gathering. When I need a sweet treat that feels fancy but is simple to throw together, this is my go-to recipe. You get moist chocolate cake with pockets of blackberry plus a swirl of berry-rich frosting that looks as good as it tastes.
My friends ask for these again and again especially in summer when berries are bursting with flavor. I first baked a batch for a cousin’s birthday picnic and even the kids licked every crumb from their fingers.
Ingredients
- All purpose flour: gives proper structure and keeps cupcakes tender. Look for unbleached flour for best taste.
- Baking soda: gives a bit of lift creating a light crumb.
- Salt: sharpens the chocolate and highlights sweetness. Use fine sea salt if possible.
- Melted unsalted butter: adds richness and moisture. Choose butter with a high milk fat percentage for flavor.
- Brown sugar: gives sweetness and caramel notes. Dark brown sugar adds extra depth.
- Eggs: bind the batter and help cupcakes rise. Large room temperature eggs are best for even mixing.
- Vanilla flavoring: brings out the chocolate and berry flavors. Choose pure vanilla extract.
- Buttermilk: gives tender crumb and subtle tang. If possible use full fat cultured buttermilk.
- Blackberries: provide tang juicy bits and natural color. Ripe fresh berries work best but you can use thawed frozen ones.
- Unsweetened cocoa powder: creates rich chocolate taste. Go for Dutch process cocoa for smooth results.
- Hot coffee or boiling water: deepens the cocoa’s flavor. Coffee makes the chocolate more intense without adding coffee taste.
- Powdered sugar: in the frosting makes it velvety smooth.
- Heavy cream: helps reach the right consistency for piping or spreading.
- Fresh blackberries and edible flowers: add visual pop. Pick plump berries and pesticide free florals.
Instructions
- Set Up the Oven:
- Preheat your oven to 350 degrees Fahrenheit so the cupcakes rise properly from the start. Line a 12 cup muffin pan with paper liners to prevent sticking and for easy cleanup.
- Mix Dry Ingredients:
- In a medium bowl whisk together flour baking soda salt and cocoa powder until everything looks even with no streaks. This ensures your cupcakes bake up uniform with chocolate flavor in every bite.
- Blend Wet Ingredients:
- In a large bowl blend melted butter and brown sugar until smooth and glossy. Crack in one egg at a time whisking well so the texture stays airy. Add vanilla buttermilk and mashed blackberries. Stir until everything is fully combined and you see lovely purple flecks scattered in the mix.
- Combine Wet and Dry Mixes:
- Pour the dry mixture into the wet ingredients in a few additions. Gently fold together using a spatula aiming for just combined with no flour visible. Overmixing will make the cupcakes tough.
- Add the Hot Liquid:
- Slowly pour in the hot coffee or water while stirring. Watch as the batter loosens and turns glossy. It should be silky and just a bit runny for a tender crumb.
- Fill the Liners:
- Spoon the batter evenly into cupcake liners filling each about three quarters full. This helps them bake up with a nice domed top.
- Bake:
- Place the tray in the hot oven and bake for eighteen to twenty two minutes. The tops should spring back lightly and a toothpick poked in the center should come out clean or with a few moist crumbs.
- Cool the Cupcakes:
- Let the cupcakes rest in the pan for five minutes to finish setting. Then carefully lift them out to a wire rack. They must be completely cool so the frosting does not melt.
- Make Blackberry Puree:
- Puree fresh or thawed blackberries in a blender until smooth. Strain through a fine sieve to remove seeds. You want a quarter cup of thick vibrant berry puree.
- Make the Frosting:
- In a large bowl whip softened butter until creamy and pale about two minutes. Gradually add powdered sugar and beat to combine. Pour in blackberry puree vanilla and one tablespoon of cream. Beat on medium high for three to four minutes until the frosting looks light and fluffy. Add more cream if needed for spreading.
- Frost and Decorate:
- Once cooled spread or pipe the blackberry frosting over cupcakes. Top with fresh blackberries shaved chocolate or edible flowers for a stunning finish. Let sit at room temp for best texture.
I adore the way the buttermilk and blackberry make each bite tender and moist. My youngest always helps top each cupcake with an extra berry and insists we add just a pinch more chocolate for luck.
Storage Tips
Keep cupcakes in an airtight container at room temp for up to two days or refrigerate for up to a week for max freshness. Bring to room temp before serving so the frosting softens and the flavor shines. If you need to prep in advance freeze unfrosted cupcakes in a single layer then thaw and frost just before serving.
Ingredient Substitutions
No buttermilk on hand Mix half a cup milk with a teaspoon of lemon juice and let it sit five minutes. Frozen blackberries work just as well as fresh. Out of heavy cream use whole milk to loosen up the frosting for spreading.
Serving Suggestions
Serve these beauties as the star at birthday picnics afternoon tea or as a wow worthy finish for a summer meal. They pair especially well with a tart fruit salad or a scoop of vanilla bean ice cream.
Cultural and Seasonal Adaptations
This cupcake takes inspiration from European berry desserts with a balance between fruit and dark chocolate. In early summer swap in raspberries or combine both for added color and tang. For a festive touch in cooler months use candied orange peel instead of berries for the topping.
These cupcakes are a showstopper at any gathering and a true treat for berry and chocolate lovers alike. Bake a batch and enjoy the smiles they bring.
