This blackberry cake is super fluffy and filled with a delicious white chocolate buttercream. It’s the perfect cake to make if you have a ton of blackberries and have no idea what to do with them!
This is my newest favorite flavor combo.
Honestly I think that both of these ingredients are highly underrated in the baking world. But when you put them together-
Bam! It’s like magic.
The tartness from the blackberries balances so well with the sweetness of the white chocolate- a total match made in heaven!
These are the ingredients you need
- unsalted butter
- granulated sugar
- eggs
- all purpose flour
- baking powder
- baking soda
- kosher salt
- whole milk yogurt
- orange juice
- fresh or frozen blackberries
How to make this blackberry cake
Making this cake is easy because your stand or hand mixer will do all the work!
Step 1: Cream the butter and sugar, until a smooth paste forms.
Step 2: Add the eggs.
Step 3: Separate the dry ingredients from the rest of the wet ingredients.
Step 4 : Switch off adding them into the batter, mixing as you go.
Step 5: Dust the blackberries with flour and add to the batter.
Step 6: Bake!
This is what the batter will look like when it’s mixed correctly:
Mixing method
There is a method to this baking madness and a reason why you can’t just dump all your ingredients into a bowl.
The reason for switching off like that is because you are using a cake mixing method called the creaming method.
The creaming method starts with creaming the butter and sugar together until fluffy.
This ensures that the butter incorporates a lot of air, which will in turn make your cake light and fluffy.
You have to switch off adding the dry and the wet ingredients because the flour needs to absorb the moisture from the wet ingredients.
It won’t be able to do that if you just dump it all in at the same time.
Also, in order for your blackberries not to sink to the bottom of the cake, you need to dust them with a little bit of flour first.
Just place the blackberries in a small bowl and dust them with flour. Now add them to the cake batter and mix slowly with a spatula so they don’t get broken up.
Prepare the cake pans
I always suggest heavily lining your cake pans with a thick layer of baking spray. Preferably one that has flour added to it like Baker’s Joy.
You can alternatively cut out parchment paper girls that are the same size as your pan and line them like that.
Make sure to avoid a situation where you can’t get the cake out of the pan.
These wilton cake pans are my favorite! You can either bake this recipe in 2 8″ cake pans or 3 6″ cake pans.
How to bake
Bake at 350° F for 30- 35 minutes for 8 inch pans and 28- 30 mins for 6″ pans.
Cakes are always done when the edges start to pull away from the cake pan. Or, if you insert a toothpick in the middle and it comes out clean.
I level off my cake layers so they have flat tops and stack nicely. This also makes it easier to fill and frost.
Take a long serrated knife and steadily cut off the top. It doesn’t have to be perfect!
Make the buttercream
To make the buttercream you will need your stand or hand mixer. Wash it out if you used it to make the cake!
How to make the buttercream:
First melt the white chocolate either in the microwave or over a double boiler.
White chocolate has the tendency to seize up so be careful when melting. Either microwave it for 30 seconds at a time, stirring in between. Or use a double boiler.
A double boiler is a small pot with an inch of water simmering over the stove with a bowl sitting on top of it.
Place the chocolate in the bowl. The steam from the water will melt the chocolate. Stir the chocolate until it melts, then set it aside to cool.
Tips on using a double boiler:
- Make sure the bowl is big enough to sit on top of the pot without hitting the water underneath.
- You only need a small amount of water to make steam. An inch is perfect
- Do not let any water get into the chocolate or the chocolate will harden and seize up!
- Let it cool for 5 minutes before making the buttercream
With the chocolate cooling, now add the softened butter and confectioners sugar to the bowl of a mixer.
Whip starting on low speed then moving up higher to combine. Slowly pour in the cooled melted chocolate, and the cream.
Mix until combined and scrape down the sides as needed.
Frosting the cake:
This buttercream recipe will make enough to fill and frost 2, 8″ cake layers or 3 6″ cake layers.

It’s not as hard as you might think!
A few more tips on making this cake:
- You can freeze it! Make sure you wrap it tightly in plastic wrap, and you can freeze it for up to 2 months. Defrost on the counter.
- Try making this into a bundt cake– just bake for 15 minutes longer and make sure you spray the pan really well. My favorite baking spray is Baker’s Joy.
- Add some lemon zest to the batter for a nice zing!

Blackberry Cake with White Chocolate Buttercream
Ingredients
For the cake
- 1 cup unsalted butter
- 2 cups granulated sugar
- 3 eggs large
- 2 1/2 cups all purpose flour
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/2 tsp kosher salt
- 1 cup yogurt whole milk
- 1/4 cup orange juice
- 6 ounces blackberries fresh or frozen
- 2 tbsp all purpose flour for dusting blackberries
For the White Chocolate Buttercream
- 1 cup white chocolate chips melted, about 6 oz
- 1 cup unsalted butter softened
- 3 cups confectioners sugar
- 1 tsp cream
Instructions
- Preheat the oven to 350° F and spray 2 9” baking pans with baking spray or line with parchment paper.
- In the bowl of a stand mixer fitted with the paddle attachment, cream the butter and sugar on medium speed for 1 minute until fluffy and pale yellow in color.
- Add in the eggs one at a time, stopping the mixer before each addition. You may have to scrape down the sides-stop the mixer.
- In a medium size bowl combine the flour, baking powder, baking soda and salt.
- In a large mixing cup or a small bowl, combine the yogurt and juice.
- Add in ⅓ of the flour mixture, and mix on low until incorporated into the mix. Then add in ½ of the yogurt and juice mixture (while still on low). Then another ⅓ of the flour, the last of the juice, and the last of the flour mixture. Stopping to scrape down the sides as needed.
- Toss the blackberries with 2 tablespoons of flour so they don’t sink to the bottom of your cake, and CAREFULLY mix them slowly into the batter. You don’t want to break them up so be careful with mixing.
- Pour the batter evenly into the two baking pans and bake for 30-35 minutes until the edges of the cake are golden brown and break away from the pan- or when the top of the cake feels firm and not jiggly.
For the White Chocolate Buttercream
- Melt the chocolate over a double boiler or melt in the microwave for 30 seconds at a time. Allow the chocolate to cool before adding to the rest of ingredients otherwise it will melt the butter.
- In the bowl of a stand mixer fitted with the paddle attachment, cream the butter and confectioners sugar on medium speed until fluffy.
- Add in the cooled, melted white chocolate and mix again on medium speed moving up to high for 30 seconds.
- Stop the mixer, scrape down the sides, and add in the half n half. Continue mixing on medium speed until light and fluffy. If you want it thinner, add in another ½ teaspoon half n half until the consistency is where you want it.
- Frost the cake layers as you wish! For tips on how to do that check out this post!
