Ingredients Breakdown

For the Blackberry Jam:

Homemade blackberry jam serves as the cornerstone of this recipe. It’s simple to make and far superior to store-bought versions, offering a fresh, tangy flavor that perfectly complements the creamy layers.

• Blackberries (3 cups / 423 grams): Fresh or frozen blackberries can be used, depending on availability. These lend a natural sweetness and tartness to the jam.
• Granulated Sugar (3 tbsp / 37 grams): Balances the tartness of the berries and enhances their natural flavor.
• Lemon Juice (2 tbsp): Adds brightness and a touch of acidity to the jam.
• Cornstarch (2 tsp): Acts as a thickening agent to give the jam its luscious consistency.
• Water (1 tbsp): Helps dissolve the cornstarch, ensuring a smooth jam.

For the Blackberry Russian Buttercream:

Russian buttercream is a luxurious, smooth frosting made with sweetened condensed milk. Adding blackberry jam transforms it into a fruity, indulgent layer.

• Unsalted Butter (12 tbsp / 170 grams): Provides a creamy base for the buttercream.
• Sweetened Condensed Milk (245 grams): Adds sweetness and a silky texture.
• Blackberry Jam (3 tbsp): Infuses the buttercream with fruity flavor and a beautiful hue.

For the Blackberry Whipped Cream:

This layer is light, airy, and slightly sweet, balancing the richness of the other components.

• Cold Heavy Cream (300 ml / 1 1/4 cup): The main ingredient for creating a fluffy whipped cream.
• Sweetened Condensed Milk (152 grams / 1/2 cup): Sweetens the whipped cream without overwhelming it.
• Blackberry Jam (3 tbsp): Adds flavor and color to the whipped cream.

To Assemble:

The final touches tie everything together.

• Chocolate Crackers (36 pieces): Serve as the cake’s structure, softening as they absorb the moisture from the creams.
• Blackberry Jam (1/4 cup): For drizzling between layers.
• Fresh Blackberries: For garnish, adding a fresh, fruity touch.

Step-by-Step Instructions

1. Prepare the Blackberry Jam

Creating the blackberry jam is the first step and can be done ahead of time.

1. Combine Ingredients: In a small saucepan, mix blackberries, sugar, and lemon juice.
2. Cook: Bring the mixture to a boil, then reduce to medium heat. Use a spoon to break down the berries as they soften, cooking for about 10 minutes.
3. Thicken: Dissolve cornstarch in water and stir it into the jam. Cook for another 1-2 minutes until the mixture thickens.
4. Strain: Push the jam through a fine-mesh sieve to remove seeds, ensuring a smooth texture. Let cool completely.

Pro Tip: Store extra jam in an airtight container in the fridge for up to 4 days. It’s perfect for toast or other desserts!

2. Make the Blackberry Russian Buttercream

This buttercream is the heart of the cake’s richness.

1. Whip the Butter: Ensure the butter is at room temperature. Beat on medium-high speed for 5 minutes until pale and fluffy.
2. Add Sweetened Condensed Milk: Gradually pour in the condensed milk, mixing until smooth. If the buttercream becomes too soft, chill it briefly, then whip again.
3. Incorporate Jam: Stir in the blackberry jam to give the buttercream its signature flavor and color. Transfer to a piping bag for easy application.

3. Prepare the Blackberry Whipped Cream

Light and airy, this layer provides a refreshing counterpoint to the rich buttercream.

1. Whip Cream: Chill your heavy cream and mixing bowl beforehand. Start whipping on low, gradually increasing to medium-high speed until stiff peaks form.
2. Add Condensed Milk and Jam: Gently fold in sweetened condensed milk and blackberry jam until combined. Avoid overmixing to maintain the cream’s fluffy texture.

4. Assemble the Cake

This is where the magic happens as the layers come together.

1. Layer Crackers: Lay 12 chocolate crackers side by side on a serving platter, forming a rectangle.
2. Add Buttercream: Pipe a border of blackberry buttercream around the edge of the cracker layer.
3. Spread Whipped Cream: Fill the center with blackberry whipped cream, smoothing it with a spatula.
4. Drizzle Jam: Add a drizzle of blackberry jam for an extra burst of flavor.
5. Repeat: Add another layer of crackers, followed by buttercream, whipped cream, and jam. Repeat this process one more time.
6. Final Touch: For the top layer, use the remaining buttercream to decorate. Garnish with fresh blackberries and optional toppings like chocolate shavings or edible gold leaf.

5. Chill and Serve

Cover the assembled cake with plastic wrap and refrigerate for at least 12 hours. This step is crucial for the crackers to soften and the flavors to meld.

The Flavor and Texture Experience

With every bite, this Blackberry Icebox Cake delivers a harmonious blend of flavors and textures. The chocolate crackers, softened to cake-like consistency, provide a subtle crunch that contrasts beautifully with the creamy layers. The blackberry whipped cream is airy and slightly tangy, while the Russian buttercream adds a rich, decadent element. Homemade blackberry jam ties everything together with its vibrant, fruity tartness. Garnished with fresh blackberries, each slice is a feast for the eyes and the palate.

• Swap blackberries with raspberries, strawberries, or a mix of berries for a different flavor profile.

The flavors meld together, creating a dessert that’s greater than the sum of its parts.
