Ingredients

• 2 cups heavy whipping cream
• 1 tablespoon vanilla bean paste or vanilla extract
• 16 ounces cream cheese, softened at room temperature
• 1 cup powdered sugar
• 2 cups fresh blackberries
• 3 tablespoons granulated sugar
• 1 tablespoon lemon juice
• 1 teaspoon cornstarch
• 2 packs Lotus Biscoff cookies

Step-by-Step Directions

• Pour the heavy whipping cream and vanilla bean paste into a large mixing bowl.
• Whisk the cream using a handheld mixer or a stand mixer fitted with a paddle attachment for two minutes until stiff peaks form.
• Transfer the whipped cream to a separate bowl and set it aside.
• Place the softened cream cheese and powdered sugar into the mixing bowl and beat them together until smooth and fully combined.
• Gently fold the whipped cream and vanilla mixture into the cream cheese mixture using a spatula until uniform.
• Take a 9-inch square casserole dish and arrange a flat base layer of Lotus Biscoff cookies across the bottom.
• Spread a generous portion of the whipped cream and cream cheese mixture evenly over the cookie layer.
• Spoon small dollops of the cooled blackberry jam over the cream layer and gently swirl or spread it out.
• Repeat the layers by adding another tier of Biscoff cookies, more cream mixture, and another layer of blackberry jam.
• Finish the assembly by topping the cake with a final layer of crushed or whole Biscoff cookies.
• Cover the casserole dish tightly with plastic cling wrap.
• Place the dish into the refrigerator to chill and set for at least twelve hours or up to two days before serving.

Homemade Blackberry Jam

• Combine fresh blackberries, granulated sugar, and lemon juice in a saucepan.
• Cook the mixture over medium heat until it breaks down and achieves a jammy consistency.
• Stir in a small amount of cornstarch to help thicken the sauce.
• Remove the saucepan from the heat and allow the jam to cool completely to room temperature before assembly.

Pro Tips by Chef

• If you prefer a traditional cake structure with clean vertical sides rather than serving directly from a casserole dish, use a 9-inch springform pan instead.
• Line the interior of the springform pan with plastic wrap so that the bottom and sides are covered before adding your layers, making it easy to lift and unmold the entire cake once fully set.
• While Lotus Biscoff cookies provide a distinct nutty caramel flavor, you can easily substitute them with golden Oreos, gingersnap cookies, or traditional graham crackers depending on your preference.
• Never add warm or hot blackberry jam directly into the cream cheese and whipped cream mixture, as the heat will melt the dairy and ruin the texture.
• Gelatin and agar-agar are completely unnecessary for this recipe because the natural pectin in the blackberries combined with a touch of cornstarch creates the ideal jam consistency.

Storage Instructions

Keep the blackberry icebox cake stored inside the refrigerator covered tightly with plastic wrap to prevent it from absorbing other refrigerator odors. The dessert will stay fresh and delicious for up to three days when refrigerated. You can also freeze the assembled cake for up to two weeks if you need to make it well in advance, though you should thaw it in the refrigerator for a few hours before slicing and serving.

This blackberry icebox cake offers a wonderful balance of creamy texture, fruity brightness, and spiced cookie crunch without the need for baking. Its straightforward preparation makes it accessible for bakers of any skill level. By preparing it ahead of time, you can spend less time in the kitchen and more time enjoying warm summer evenings with the people you love.
