There is nothing like the vibrant burst of blackberries in this tender cake balanced with a tangy cream cheese frosting. Each bite is moist and full of fruity flavor with beautiful flecks of purple from the berries, making it perfect for summer gatherings or any time you want to impress.
The first time I baked this cake my kitchen smelled like a summer garden and everyone came running in for second slices. It quickly became our family’s special occasion favorite.

Step-by-Step Instructions

- In a large bowl whisk flour baking powder baking soda and salt until no streaks remain Sifting helps create a light crumb
- Cream Butter and Sugar:
- Using an electric mixer cream butter and granulated sugar on medium speed until pale and fluffy about four to five minutes This step creates air for a tender cake

- Beat in eggs one at a time ensuring each egg fully combines before adding the next Pour in vanilla extract and mix until just blended
- Combine Wet and Dry Ingredients:
- Alternately add the flour mixture and buttermilk to the butter mixture in several additions Begin and end with flour Mix on low speed to prevent overmixing which makes a tough cake
- Fold in Blackberries:
- Gently fold in fresh blackberries using a spatula Spreading them evenly prevents one side from getting soggy
- Bake:
- Pour batter into your prepared pan and smooth the top Place in center oven rack and bake for fifty to fifty five minutes Check with a toothpick inserted in the center if it comes out clean the cake is done Let it cool in the pan for fifteen minutes then invert onto a wire rack to cool fully

- Finish the Cake:
- Once the cake is completely cool frost generously over the top and sides Decorate with extra blackberries Press berries gently into the icing so they stay Put the finished cake in the fridge for about thirty minutes before slicing for clean pieces

My favorite part is biting into a warm berry hidden in a fluffy crumb often making me think of foraging berries as a child. Every time I bake this cake my kids sneak a few berries off the top before I even finish the photos.
Storage Tips
Store leftover cake in an airtight container in the fridge The cream cheese frosting means it cannot be kept at room temperature more than a few hours To keep the cake extra moist wrap it in plastic before refrigerating and it will stay soft for up to four days
Ingredient Substitutions
If fresh blackberries are out of season substitute with frozen ones Do not thaw them before folding into the batter to prevent a gray streak throughout Greek yogurt with a splash of lemon juice can replace buttermilk in a pinch If you like a different berry try raspberries for a twist

Serving Suggestions
This cake is lovely served slightly chilled with extra fresh berries Scatter some lemon zest on top for brightness or a few mint leaves for color For gatherings present the cake on a simple white plate to let the purple berries pop
A Bit of Blackberry Cake History
Blackberry cake recipes have deep Southern roots often made on family farms when berries are in season The natural juiciness and color meant that home bakers did not need fancy ingredients to create a showstopping dessert For my family blackberry picking was always a sign spring was turning into summer

Using buttermilk and room-temperature ingredients helps maintain a tender, moist crumb. Avoid overbaking and always test for doneness with a toothpick.

Yes, you can use frozen blackberries. Toss them in flour before adding to the batter to prevent excess moisture and bleeding.
- → What’s the best way to prevent berries from sinking?
Lightly coat blackberries in flour to help suspend them evenly throughout the batter during baking.
