How to Make Blackberry Cake
Step 1: Prepare Your Pans
Grease your 8-inch cake pans with butter or non-stick spray. Then, line them with parchment paper for easier removal after baking.
Step 2: Mix Dry Ingredients
In a mixing bowl, combine:
1. Cake flour
2. Baking powder
3. Kosher salt
Whisk until well blended.
Step 3: Combine Wet Ingredients
In another bowl, mix:
1. Whole milk
2. Sour cream
3. Egg whites
Beat these ingredients until smooth.
Step 4: Cream Butter and Sugar
Using an electric mixer, beat the unsalted butter with granulated sugar until pale and fluffy. This should take about 3-5 minutes.
Step 5: Add Lemon Zest and Juice
Mix in lemon zest and lemon juice into the creamed butter mixture until combined.
Step 6: Combine Everything
Gradually add the dry ingredients to the wet mixture while mixing on low speed until just combined. Do not overmix!
Step 7: Bake the Cakes
Divide the batter evenly between prepared pans. Bake in a preheated oven at 350°F (175°C) for about 30-35 minutes or until a toothpick inserted comes out clean.
Step 8: Cool Layers
Once baked, let the cakes cool in their pans for about 10 minutes before transferring them to a cooling rack to cool completely.

With Fresh Whipped Cream

Garnished with Mint Leaves

How to Perfect Blackberry Cake
To achieve the ultimate Blackberry Cake, consider these essential tips for baking success.
- Use Room Temperature Ingredients: Ensure all ingredients, especially butter and eggs, are at room temperature for better mixing and texture.
- Sift Your Flour: Sifting cake flour helps incorporate air, resulting in a lighter cake that rises beautifully.
- Don’t Overmix Batter: Mix until just combined. Overmixing can lead to dense cake layers that don’t rise well.
- Test for Doneness: Use a toothpick inserted into the center; if it comes out clean, your cake is ready!
- Cool Completely Before Frosting: Allow the layers to cool fully before applying mascarpone buttercream. This prevents melting and sliding.
- Layer Flavors: Enhance each layer with lemon zest or additional blackberry curd for an extra burst of flavor throughout the cake.

Best Side Dishes for Blackberry Cake
Pairing side dishes with your Blackberry Cake can create a delightful meal experience. Consider these options:
- Fruit Salad: A light fruit salad complements the cake’s richness, offering freshness with every bite.
- Lemon Sorbet: The tartness of lemon sorbet will enhance the citrus notes in the cake while providing a refreshing contrast.
- Cheese Platter: A selection of mild cheeses can balance the sweetness, adding depth to your dessert table.
- Chocolate Mousse: Rich chocolate mousse pairs wonderfully with fruity desserts like blackberry cake, creating a luxurious combination.
- Pecan Pie Bars: For those who enjoy nutty flavors, pecan pie bars offer a different sweet treat that contrasts beautifully with berries.
- Coffee or Espresso: Serving coffee or espresso alongside will provide a robust finish that complements dessert perfectly.
Common Mistakes to Avoid
Baking a perfect Blackberry Cake can be tricky. Here are some common mistakes to watch out for.
- Using cold ingredients: Cold butter or eggs can affect the cake’s texture. Always use room temperature ingredients for a fluffy cake.
- Overmixing the batter: This can lead to a dense cake. Mix just until combined to keep it light and airy.
- Skipping the lemon zest: The zest adds essential flavor. Don’t skip it if you want a refreshing taste in your Blackberry Cake.
- Not measuring flour correctly: Too much flour can make the cake dry. Use the spoon-and-level method for accurate measurements.
- Ignoring baking time: Every oven is different. Start checking your cake a few minutes before the recommended baking time to avoid overbaking.
