Why Blackberry Cake?

Blackberries are not only delicious, but they’re also rich in antioxidants, fiber, and vitamins.

When folded into a simple cake batter, they add pops of tartness that balance beautifully with the sweet, buttery flavor.

Plus, their deep purple hue adds a stunning visual to your dessert table.

Ingredients You’ll Need

Before diving into the process of how to prepare blackberry cake, gather these essential ingredients:

1½ cups fresh blackberries (or frozen, thawed and drained)
2 cups all-purpose flour
1½ teaspoons baking powder
½ teaspoon baking soda
¼ teaspoon salt
½ cup unsalted butter (softened)
1 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
½ cup plain yogurt or sour cream
¼ cup milk
Zest of 1 lemon (optional, for added brightness)
Powdered sugar or glaze for topping (optional)

Step-by-Step Guide on How To Prepare Blackberry Cake

1. Preheat and Prep

Begin by setting your oven to 350°F (175°C) so it has enough time to get to the right temperature before you bake.

While it’s heating up, prepare your baking pan. You can either grease it with a little butter or oil and then dust it lightly with flour, or simply line it with parchment paper.

This step ensures your cake doesn’t stick and comes out easily after baking.

2. Mix Dry Ingredients

In a medium-sized bowl, add the flour, baking powder, baking soda, and salt. Use a whisk or fork to mix them together.

These dry ingredients help the cake rise and keep its shape, and mixing them ahead of time ensures they’re evenly distributed in the batter.

3. Cream the Butter and Sugar

Take a large mixing bowl and add your softened butter and sugar.

Using a hand mixer or stand mixer, beat them together on medium speed until the mixture becomes light, fluffy, and pale in color.

This step is important because it adds air to the batter, making your cake light and soft.

4. Add Eggs and Vanilla

Crack the eggs in one at a time, mixing well after each one. This helps them blend smoothly into the batter.

Once both eggs are in, add your vanilla extract (and lemon zest if you’re using it) and mix again.

The eggs help bind the batter, and the vanilla gives the cake a lovely flavor.

5. Combine Wet and Dry

Now, it’s time to mix everything together. Add a third of the dry ingredients to the wet mixture and stir gently.

Then add half of the yogurt (or sour cream), and stir again. Repeat this process—add another third of the dry mix, the rest of the yogurt, and finally the last third of the dry ingredients.

Pour in the milk and stir just until everything is well combined. Don’t overmix; a few small lumps are okay.

6. Fold in Blackberries

Gently add the blackberries to your batter. If you’re worried about them sinking, you can toss them in a little flour before mixing.

Use a spatula or spoon to fold the berries in slowly and carefully so they don’t break apart too much.

This keeps the cake colorful and gives you juicy bites of fruit throughout.

7. Bake

Pour your finished batter into the prepared cake pan. Use a spatula to smooth the top so it bakes evenly.

Place it in the oven and bake for 35 to 45 minutes. Start checking at the 35-minute mark by inserting a toothpick in the center—if it comes out clean or with a few crumbs (not wet batter), the cake is done.

Let it cool in the pan for 10 minutes before carefully removing it and placing it on a rack to cool fully.

8. Finish and Serve

Once your cake is cool, you can add a final touch. Sprinkle some powdered sugar on top using a small sieve, or drizzle a simple glaze made from lemon juice and powdered sugar.

You can serve it as-is or with a scoop of vanilla ice cream or whipped cream for extra indulgence.

Enjoy your homemade blackberry cake—it’s ready to impress.

Common Mistakes to Avoid

Overmixing the batter: This can lead to a dense, rubbery cake. Stir until just combined.
Using too many berries: More is not always better—too many blackberries can make the cake soggy.
Skipping the flour toss: Coating blackberries in flour helps them stay suspended in the batter instead of sinking.
Not letting it cool: Cutting the cake too soon can cause it to fall apart. Let it rest before slicing.
