Ingredients

2 cups all-purpose flour
The foundation of the cake, all-purpose flour provides structure and stability. Its protein content allows the cake to rise properly while contributing to the desired texture.
2 cups granulated sugar
Sugar enhances sweetness, balances acidity from the blackberries, and plays a crucial role in the cake's moisture content. It helps create a tender crumb and aids in browning.
1 cup unsalted butter, softened
Butter adds richness and flavor to the cake. Its fat contributes to a moist crumb and enhances the overall taste. Softening it ahead of time promotes easier blending.
4 large eggs
Eggs act as a binding agent, holding the cake together while also providing moisture and structure. They add richness and help the cake rise through aeration.
1 cup milk
Milk hydrates the dry ingredients and contributes to the cake's moisture. It creates a soft texture and enhances the overall flavor profile.
1 teaspoon baking powder
As a leavening agent, baking powder helps the cake rise, providing that light and fluffy texture we all love. It reacts with moisture and acid in the batter.
1/2 teaspoon baking soda
Baking soda works in conjunction with acidic components, providing additional leavening and contributing to the cake’s tenderness.
1/2 teaspoon salt
Salt enhances flavor by balancing the sweetness, bringing out the best in the other ingredients and ensuring a well-rounded taste.
2 cups fresh blackberries, pureed
Pureed blackberries impart a natural sweetness and vibrant color to the cake, enriching the batter with fruity flavor while adding moisture.
2 cups powdered sugar
Powdered sugar is essential for frosting; it creates a smooth, sweet, and spreadable texture. Its fine consistency allows for easy incorporation with other frosting ingredients.
1/2 cup unsalted butter, softened
Like in the cake, softened butter in the frosting provides creaminess and enhances flavor, allowing for a velvety, spreadable consistency.
1/4 cup blackberry puree
Adding blackberry puree to the frosting gives it a beautiful purple hue and imparts delightful berry flavor, making it a perfect match for the cake.
1-2 tablespoons heavy cream
Heavy cream helps achieve the right consistency in frosting, making it luxuriously smooth and easy to spread while enhancing the richness.

Directions & Preparation

Step 1: Preheat the oven to 350°F (175°C). Grease and flour three 9-inch round cake pans.

Preheating the oven establishes the correct baking environment for the cake, ensuring even cooking. Greasing and flouring the pans will prevent the cake from sticking, making it easier to remove them once baked.

Step 2: In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.

Creaming butter and sugar introduces air into the mixture, creating a light and fluffy texture that will help the cake rise. This step is crucial for achieving the cake's desired texture, so take your time.

Step 3: Add the eggs one at a time, mixing well after each addition, then add the milk and blackberry puree.

Incorporating eggs one at a time ensures thorough mixing and emulsification. This step contributes to a stable structure while the milk and berry puree add moisture and flavor, enriching the overall batter.

Step 4: In another bowl, whisk together flour, baking powder, baking soda, and salt.

Whisking the dry ingredients separately ensures even distribution of the leavening agents and salt, preventing clumping and allowing for uniform rising during baking.

Step 5: Gradually add the dry ingredients to the wet mixture, mixing just until combined.

This step is vital as overmixing can lead to a dense, tough cake. Mixing just until the ingredients are combined prevents gluten development, yielding a tender crumb.

Step 6: Divide the batter evenly among the prepared pans and smooth the tops.

Dividing the batter equally ensures uniform layers, promoting even baking and consistent texture throughout. Smoothing the tops allows for a flat surface, which is beneficial for stacking.

Step 7: Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.

Monitoring baking time is essential; the cake is done when a toothpick inserted in the center comes out clean or with a few moist crumbs. Overbaking can lead to dryness, so keep an eye on them.

Step 8: Allow the cakes to cool in the pans for 10 minutes, then transfer to wire racks to cool completely.

Cooling in the pans allows the structure to set before moving them. Transferring to wire racks helps cool the cakes evenly, preventing sogginess from steam trapped in the pans.

Step 9: While the cakes cool, prepare the frosting by creaming the softened butter with powdered sugar.

Creaming the butter with powdered sugar combines the two ingredients effectively, creating a fluffy base for the frosting. This step establishes the primary consistency and sweetness.

Step 10: Mix in the blackberry puree and heavy cream until smooth and well combined.

Adding blackberry puree not only provides the aesthetic purple color but also infuses the frosting with fruitiness. Adjusting with cream achieves the desired spreadable consistency.

Step 11: Once cooled, place one cake layer on a serving plate and spread a layer of frosting on top.

Layering frosting between the cake layers helps maintain moisture and adds flavor. Be sure to spread evenly for a neat presentation and balanced taste in each bite.

Step 12: Repeat with the second cake layer and finish by placing the third layer on top.

Stacking the layers properly ensures stability and symmetry in your cake. It also creates a beautiful multi-layer effect when cut, making it visually appealing.

Step 13: Frost the top and sides of the cake with the remaining blackberry frosting.

Frosting the entire cake provides a finished look and a delicious exterior. Use an offset spatula for smooth application, and have fun with design patterns for a personal touch.

Step 14: Garnish with fresh blackberries on top for decoration.

Adding fresh blackberries as a garnish not only enhances the cake’s visual allure but also invites guests to enjoy more of that delightful blackberry flavor with every slice. Choose evenly sized berries for best presentation.
