How to Make White Chocolate Blackberry Poke Cake

Preheat and Prepare the Cake

Preheat your oven to 350°F (175°C). Prepare the white cake mix according to the package instructions, adding eggs, oil, and water. Stir in 1 cup of white chocolate chips for extra flavor. Pour the batter into a greased 9×13-inch baking pan and bake as directed. Allow the cake to cool completely before adding the filling.

Make the Filling

In a bowl, mix the sweetened condensed milk and blackberry jam until smooth and well combined.

Poke the Cake

Using the handle of a wooden spoon, poke holes evenly across the surface of the cooled cake. This allows the filling to soak into the cake for moist, flavorful layers.

Add the Filling

Pour the blackberry-condensed milk mixture over the cake, letting it seep into the holes and saturate the layers evenly.

Prepare the Ganache

In a small saucepan, combine fresh blackberries, sugar, and water. Cook over medium heat until the berries break down and the mixture thickens. Strain to remove solids, creating a smooth blackberry sauce. Place the white chocolate chips and heavy cream in a bowl, then pour the hot sauce over them. Stir gently until smooth and glossy.

Add Ganache and Decorate

Pour the ganache evenly over the soaked cake, spreading gently with a spatula if needed. Top with a generous layer of whipped cream and garnish with fresh blackberries for a beautiful finish.

Tips for Success

• Ensure the cake is completely cooled before poking holes to prevent crumbling
• If using frozen blackberries for the sauce, thaw and drain before cooking
• For a more intense flavor, reduce the blackberry sauce slightly before straining
• Avoid overheating the chocolate to maintain a smooth, glossy ganache
• Refrigerate the cake for up to 3 days; bring to room temperature before serving

Equipment Needed

• 9×13-inch baking pan
• Mixing bowls
• Whisk and spatula
• Saucepan for blackberry sauce
• Strainer for smooth ganache
• Wooden spoon handle or skewer for poking holes

Recipe Variations

• Mixed Berry Version: Add raspberries or blueberries to the filling or ganache
