Ingredients

  • 2 cups all-purpose flour
    Flour acts as the foundation of any cake, providing structure and stability. The gluten in all-purpose flour forms a network that traps air, leading to a light and fluffy texture. Opting for all-purpose flour ensures the right balance of tenderness and strength.
  • 1 cup granulated sugar
    Sugar serves multiple roles in a cake—mostly as a sweetener. It also contributes to the cake's texture, helps with browning through caramelization during baking, and enhances the overall flavor profile.
  • 1/2 cup unsalted butter, softened
    Butter not only adds richness and flavor but also plays a crucial role in creating a moist cake. The fat in butter coats the flour particles, resulting in a tender crumb, while beating it with sugar incorporates air for leavening.
  • 3 large eggs
    Eggs are essential for binding ingredients together, providing structure and moisture. They also help in leavening and emulsion, leading to a well-risen and cohesive cake.
  • 1 cup milk
    Milk hydrates the dry ingredients and contributes moisture to the cake, making it soft and tender. It also helps to create a smooth batter, ensuring that all ingredients are well combined.
  • 1 cup fresh blackberries, pureed
    Pureed blackberries infuse the cake with intense blackberry flavor, creating a fruity richness that stands out. Additionally, the natural sugars from the fruit can help enhance sweetness without relying solely on granulated sugar.
  • 1 teaspoon baking powder
    Baking powder acts as a leavening agent, helping the cake rise by producing carbon dioxide gas when combined with moisture and heat. This results in a light, airy texture that is essential for layer cakes.
  • 1/2 teaspoon baking soda
    Baking soda, a base, helps to create a balanced pH in the batter when combined with acidic ingredients, such as buttermilk or pureed fruit. This reaction produces additional leavening and contributes to a tender crumb.
  • 1/4 teaspoon salt
    Salt sharpens and enhances flavors in a cake. It rounds out the sweetness and balances the overall taste, preventing the cake from being bland.
  • 2 cups powdered sugar
    Powdered sugar is key to creating the frosting, providing sweetness and a smooth texture. It dissolves easily, allowing for a creamy consistency that spreads beautifully on the cake.
  • 1/2 cup unsalted butter, softened (for frosting)
    Like in the cake, butter adds richness and helps create a creamy texture in the frosting. It helps stabilize the frosting while providing a buttery flavor that complements the blackberries.
  • 1/4 cup blackberry puree (for frosting)
    This puree not only colors the frosting a lovely shade of purple but also adds flavor, tying the frosting back to the cake itself. It enhances both the visual appeal and the taste.
  • 1 tablespoon heavy cream
    Heavy cream adds richness and improves the consistency of the frosting, making it easier to spread. It helps achieve that perfect creamy texture that will beautifully coat the cake.

Directions & Preparation

Step 1: Preheat the oven to 350°F (175°C) and prepare your cake pans.

Preheating the oven ensures that your cake batter starts baking immediately, helping it to rise properly. Preparing your cake pans with butter or non-stick spray and lining them with parchment paper prevents sticking, allowing for easy removal of the cakes once baked.

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

This step is crucial for incorporating air into your batter. The process of creaming butter and sugar breaks down the sugar granules, which aerates the mixture and contributes to a light cake. Aim for a pale and fluffy texture that indicates sufficient aeration.

Step 3: Add the eggs one at a time, mixing well after each addition.

Incorporating eggs gradually allows for better emulsification, resulting in a uniform batter. Eggs contribute moisture, structure, and richness, so make sure they are well combined for optimal texture.

Step 4: Add the blackberry puree and mix until just combined.

Introducing the blackberry puree not only enhances flavor but also adds moisture to the batter. Mix just until combined to avoid overworking the flour, ensuring a tender crumb.

Step 5: In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.

Whisking the dry ingredients separately ensures that the leavening agents and salt are evenly dispersed throughout the flour. This step prevents any lumps and promotes uniform rising during baking.

Step 6: Gradually add the dry ingredients to the wet mixture, alternating with the milk, and mix until smooth.

Alternating the addition of dry and wet ingredients helps maintain a balanced consistency in the batter. Mixing just until combined is key for a fluffy cake; overmixing can lead to denser textures due to gluten development.

Step 7: Divide the batter evenly between the prepared cake pans and smooth the tops.

Ensuring even division of the batter promotes uniform baking and helps in stacking the layers later. Smoothing the tops also aids in even rising and creates a structure that is easier to frost.

Step 8: Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.

Monitoring baking time is essential, as overbaking can lead to a dry cake. When the toothpick comes out clean, it indicates that the cake is fully cooked while remaining moist.

Step 9: Allow the cakes to cool in the pans for 10 minutes, then transfer to a wire rack.

Cooling the cakes briefly in the pans allows them to set and reduces the risk of crumbling. Transferring them to a wire rack ensures they cool evenly, preventing sogginess from steam.

Step 10: Prepare the frosting by beating together softened butter and powdered sugar until smooth and creamy.

This process achieves the desired creamy consistency in the frosting. Beating the sugar and butter together properly incorporates air, which results in a lighter frosting.

Step 11: Add the blackberry puree and heavy cream, mixing until fully combined and smooth.

The addition of blackberry puree not only colors the frosting but also enhances its flavor. The heavy cream contributes to the spreading consistency needed for a luscious frosting texture.

Step 12: Assemble the cake by placing one layer on a serving plate, spreading frosting on top, and repeating with the second layer.

Layering the frosting between the cakes promotes moisture and flavor integration. It also provides a beautiful base for the outer coat of frosting.

Step 13: Frost the top and sides of the cake with the remaining frosting, creating a smooth finish.

A well-frosted cake not only looks appealing but also seals in moisture. Use an offset spatula for a smooth and even application, allowing the cake to shine.

Step 14: Garnish with fresh blackberries or additional decorative touches if desired.

Garnishing adds visual interest and enhances the appeal of the cake. It also provides a hint about the flavors within, inviting guests to indulge.
