This velvet cake with blackberries blends the rich softness of a classic velvet treat with the fresh zing of ripe blackberries. It’s fancy but still cozy. The tender crumb mixes perfectly with the berry tang, making it ideal for celebrations or just treating yourself any day.

The first time I made this cake, it quickly became a household favorite. The smooth cake paired with tangy blackberry frosting still gets friends asking me to bake it when they visit.

Gather Your Ingredients

  • All-purpose flour: the foundation for a tender but strong cake, sift it so the cake stays light
  • Granulated sugar: sweetness that helps keep the cake soft, finer sugar blends more smoothly
  • Unsalted butter at room temperature: key for moisture and taste, should be soft but not melted
  • Large eggs warmed up a bit: add structure and richness, room temperature eggs mix in better
  • Buttermilk warmed: helps tenderize the cake with acidity and works with baking soda to make it rise
  • Fresh blackberries: the star here, choose ripe, juicy ones without bruises for best taste
  • Baking powder: lifts the cake for fluffiness, fresh stuff works best
  • Baking soda: teams up with buttermilk for extra rise and softness
  • Salt: boosts all the other flavors, sea or kosher salt works fine
  • Pure vanilla extract: gives warmth and depth to the cake's flavor
  • Lemon zest (optional): adds a fresh citrus twist to brighten the berries
  • For frosting: unsalted butter, powdered sugar, cream cheese, blackberry puree, vanilla, and a pinch of salt all mix to make a smooth, tangy-sweet finish

How to Make It

Blackberry Syrup:
Simmer fresh blackberries with sugar and a bit of water on medium heat for about 8 to 10 minutes till it thickens. Lightly mash everything and push the mix through a fine sieve to get rid of seeds. Let the puree cool down completely. Keep half a cup for the cake batter and about a third cup for the frosting.
Oven and Prep:
Heat your oven to 350°F (175°C). Grease and flour two 8-inch round pans, then cover their bottoms with parchment paper so the cake comes out easily.
Blend Dry Ingredients:
Whisk together the sifted flour, baking powder, baking soda, and salt in a medium bowl until they’re mixed evenly. This helps the cake rise nice and even.
Beat Butter and Sugar:
Use a hand or stand mixer to whip the room temp butter with granulated sugar on medium speed for about 3 to 4 minutes until it’s pale and fluffy. This makes the cake super tender.
Add Eggs and Flavors:
One at a time, add eggs while beating well after each. Stir in vanilla and optional lemon zest for a little extra zing.
Mix Liquids:
In another bowl, whisk buttermilk with half a cup of the chilled blackberry puree to get your wet ingredients ready.

One unforgettable moment was when I served this at a backyard summer bash and everyone wanted the instructions after tasting it.

Flavor Boosters

Wrap the cake tight in plastic wrap or store in a sealed container at room temp to keep it fresh for a couple of days. For longer keeping, pop it in the fridge and warm it up before eating so it tastes best. The frosting might soften in the fridge, so a little chill before frosting helps it keep shape.

Serving Suggestions

Top slices with whipped cream or a scoop of vanilla bean ice cream for a fancier touch. You can add fresh berries or even some edible flowers to make it stand out at any get-together. A light tea or sparkling wine amps up the experience for celebrations.

Creative Twists

If blackberries aren't around, try fresh or frozen raspberries or blueberries since they give a similar punch of color and tartness. For a dairy-free option, swap buttermilk for coconut milk mixed with a tablespoon of lemon juice and use a vegan cream cheese for the frosting.

Common Questions About This Recipe

→ Can I use frozen blackberries instead of fresh?

Sure, frozen blackberries work but make sure to thaw and drain them well so the cake doesn’t get too wet and change its texture.

First, grease your pans really well, then line them with parchment paper, and finally sprinkle a bit of flour before you pour in your batter.

Cook the blackberries with sugar till soft, then mash them gently and push the mix through a fine mesh sieve to get rid of seeds and leave a smooth puree.

→ Can I make the frosting ahead of time?

Absolutely. You can make the frosting ahead and chill it. Just bring it back to room temp before spreading it so it goes on nice and smooth.

Keep your cake covered tight in the fridge and it should stay fresh for up to 3 days with great taste.

Ingredients You’ll Need

→ Dry Ingredients

01 Salt, half a teaspoon
02 Two teaspoons baking powder
03 Two and a half cups plain flour
04 Half a teaspoon baking soda

→ Wet and Flavoring Ingredients

05 One cup softened unsalted butter
06 Three large eggs at room temp
07 Two teaspoons vanilla extract
08 One cup room temperature buttermilk
09 One and three quarters cups white sugar
10 Optional: a teaspoon of lemon zest

→ Blackberries

11 Fresh blackberries, one and a half cups, plus extras to top

→ Frosting Ingredients

12 Four ounces cream cheese, softened
13 One teaspoon vanilla extract
14 One-third cup blackberry sauce made from cooked berries
15 A pinch of salt
16 Three and a half cups powdered sugar
17 One cup unsalted butter, softened

How to Make It

Step 01

Start by cooking 1 1/2 cups blackberries with a bit of sugar and some water in a small pot over medium heat for 8 to 10 minutes until thick. Mash gently and press through a fine sieve to get rid of seeds. Let it chill well. Set aside half a cup for the batter and a third cup for the frosting.

Step 02

Heat your oven to 350°F. Grease two 8-inch cake pans, line their bottoms with parchment, and dust flour on top so the cake doesn’t stick.

Step 03

Whisk flour, baking powder, baking soda, and salt together in a bowl.

Step 04

Beat softened butter with sugar in a mixer at medium speed. Keep going till it’s fluffy and light, about 3 to 4 minutes.

Step 05

Add eggs one by one, making sure each is mixed in well. Then stir in vanilla and lemon zest if you’re using it.

Step 06

In another bowl, whisk together the buttermilk and the blackberry sauce you saved earlier (half a cup).

Step 07

Slowly fold the dry stuff into the wet mixture just until it’s mixed. Then stir in the rest of the blackberry puree.

Step 08

Pour the batter evenly into your pans. Bake for 30 to 45 minutes or until a toothpick comes out clean. Cool the cakes in the pans for 10 minutes before moving them onto wire racks to cool off completely.

Step 09

Mix butter and cream cheese until smooth and fluffy, around 2 minutes. Slowly add powdered sugar, the remaining blackberry sauce, vanilla, and a pinch of salt. Beat until creamy and light for about 3 minutes. Chill if it feels too soft.

Step 10

Put some frosting between the cake layers and cover the outside too. Top with fresh blackberries for a pretty finish.

Extra Suggestions

  1. To get rid of most seeds in the blackberry mix, press it through a fine sieve after cooking.
