How to Make Blackberry Cake
Step 1: Prepare Your Oven and Pans
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. Line the bottom with parchment paper for easy removal.
Step 2: Mix Dry Ingredients
In a large bowl, whisk together:
* Cake flour
* Granulated sugar
* Baking powder
* Kosher salt
Make sure there are no lumps in your dry ingredients.
Step 3: Combine Wet Ingredients
In another bowl, combine:
* Whole milk
* Sour cream
* Egg whites
* Lemon zest
* Lemon juice
Mix until smooth.
Step 4: Cream Butter and Sugar
In your stand mixer bowl, beat:
* Unsalted butter
* Granulated sugar
Beat on medium speed until light and fluffy. This should take about 5 minutes.
Step 5: Combine Mixtures
Gradually add the wet mixture into the creamed butter mixture. Mix until just combined. Slowly fold in the dry ingredients using a rubber spatula until no streaks remain.
Step 6: Bake the Cakes
Divide the batter evenly between prepared pans. Bake for about 30–35 minutes or until a toothpick inserted comes out clean. Let cool completely before frosting.
How to Serve Blackberry Cake
Serving a delicious blackberry cake can elevate any occasion. Whether it’s a birthday party or a cozy family gathering, the presentation and pairings can make all the difference.
Pair it with Fresh Berries
- Use a handful of fresh blackberries on top of each slice for added color and flavor.
Add a Scoop of Ice Cream
- A scoop of vanilla or lemon ice cream complements the tartness of the blackberries beautifully.
Drizzle with Lemon Curd
- A light drizzle of lemon curd adds an extra zing that enhances the cake’s lemon flavor.
Garnish with Edible Flowers
- Adding Queen Anne’s Lace flowers can create a stunning visual appeal, making your blackberry cake look even more enticing.
Serve with Whipped Cream
- Lightly sweetened whipped cream provides a fluffy contrast to the rich mascarpone buttercream.
Create a Layered Dessert
- Dice leftover blackberry cake and layer it in a glass with yogurt and more blackberries for an elegant dessert parfait.
How to Perfect Blackberry Cake
To achieve the ultimate blackberry cake, consider these essential tips for baking success.
- Use Room Temperature Ingredients: Ensure that your butter, eggs, and milk are at room temperature for an even batter.
- Sift Your Flour: Sifting helps aerate the flour, leading to a lighter texture in your cake layers.
- Don’t Overmix: Mix just until combined. Overmixing can lead to dense cakes due to gluten development.
- Check Doneness: Insert a toothpick into the center; if it comes out clean or with few crumbs, your cake is done.
- Cool Completely: Allow your cakes to cool completely before frosting; this prevents melting of the buttercream.
- Store Properly: Keep any leftover blackberry cake in an airtight container in the fridge for freshness.

Best Side Dishes for Blackberry Cake
Pairing side dishes with blackberry cake can enhance your dessert experience. Here are some great options that complement the flavors beautifully.
- Lemon Sorbet: A refreshing palate cleanser that balances the sweetness of the cake.
- Berry Compote: A warm mixed berry compote adds richness and depth when spooned over slices.
- Coconut Macaroons: Chewy macaroons offer a delightful contrast to the soft texture of the cake.
- Chocolate Ganache: Rich chocolate ganache drizzled over slices will satisfy any chocolate lover’s cravings.
- Almond Biscotti: Crunchy almond biscotti provide a perfect texture contrast when served alongside slices of blackberry cake.
- Pistachio Crumble: A nutty crumble adds both flavor and crunch, enhancing each bite of the cake.
Common Mistakes to Avoid
Making a Blackberry Cake can be a delightful experience, but certain mistakes can lead to disappointing results. Here are some common pitfalls to watch out for:
- Skipping Room Temperature Ingredients: Using cold ingredients directly from the fridge can prevent your cake from rising properly. Ensure all ingredients, especially eggs and butter, are at room temperature for a smooth batter.
- Overmixing the Batter: Overmixing can develop gluten in the flour, leading to a dense cake. Mix just until combined to keep your Blackberry Cake light and fluffy.
- Underbaking the Cake: Not baking your cake long enough can result in a soggy center. Always check for doneness by inserting a toothpick; it should come out clean when the cake is done.
- Ignoring Oven Temperature Accuracy: If your oven temperature is off, it can affect baking time and texture. Use an oven thermometer to ensure you’re baking at the right temperature.
- Not Straining Blackberry Curd: Failing to strain your blackberry curd can lead to unwanted seeds in your cake layers. Always strain to achieve a smooth and silky consistency.
Storage & Reheating Instructions
Refrigerator Storage
- Duration: Store your Blackberry Cake in the refrigerator for up to 5 days.
- Container: Keep it in an airtight container to maintain freshness and prevent drying out.
Freezing Blackberry Cake
- Duration: You can freeze slices of Blackberry Cake for up to 3 months.
- Container: Wrap each slice tightly in plastic wrap and then place them in a freezer-safe bag or container.
Reheating Blackberry Cake
- Oven: Preheat your oven to 350°F (175°C). Wrap the cake in aluminum foil and heat for about 10-15 minutes until warmed through.
- Microwave: Place a slice on a microwave-safe plate, cover with a damp paper towel, and heat for 20-30 seconds. Be careful not to overheat.
- Stovetop: Use a skillet over low heat; cover with a lid and warm for about 5 minutes. This method helps retain moisture without drying out the cake.
