Ingredients You’ll Need
This recipe comes together with a handful of surprisingly simple ingredients, each playing a crucial role. From the soft white cake base to juicy berries and creamy ganache, these elements create the signature flavor, velvety crumb, and dramatic color pop that define this cake.
- White cake mix (plus eggs, oil, and water): The perfect fuss-free foundation that bakes up light and pillowy, ready to absorb every drop of ganache.
- Fresh blackberries (for cake and garnish): These bring juicy bits of tart, fruity goodness to each bite and extra visual appeal on top.
- White chocolate chips: Use a good-quality brand for a creamy, melt-in-your-mouth ganache that infuses the cake with silky sweetness.
- Heavy cream: Blends with white chocolate to form that luxurious, pourable ganache.
- Granulated sugar: Sweetens the tangy blackberry sauce just enough—taste your berries and adjust as needed.
- Lemon juice: Adds a bright, citrusy note to balance the sweetness and enhance the berry flavor.
- Cornstarch + water: Thickens the blackberry sauce so it sits beautifully on top of the cake without soaking through.
- White chocolate shavings: For that irresistibly luxurious garnish that hints at the ganache inside.
How to Make Velvety White Chocolate & Blackberry Poke Cake
Step 1: Bake the Cake
Preheat your oven as per the instructions on your cake mix box, and lightly grease a 9×13-inch baking dish. Prepare the white cake mix batter as the package directs, but before pouring the batter into your pan, gently fold in one cup of fresh blackberries. This little extra step gives you pop-of-flavor surprises throughout. Spread the batter in your dish and bake according to the package timing. Once done, let the cake cool slightly—just enough that it’s still warm, but won’t burn your fingers.
Step 2: Poke the Cake
Now comes the signature move! Using the handle of a wooden spoon or a thick skewer, poke holes all over the warm cake. Don’t be shy—poke deep, wiggling the utensil a bit to create channels for the ganache. This is what makes a poke cake so decadent: every bite gets infused with that rich, flavorful filling.
Step 3: Prepare the White Chocolate Ganache
In a microwave-safe bowl, add your white chocolate chips and heavy cream. Heat in 30-second intervals, stirring in between, until the mixture melts together into a smooth, glossy ganache. Be patient and stir well to avoid overheating; you want that luxurious, pourable texture.
Step 4: Pour the Ganache
While both the cake and ganache are still warm, slowly pour the ganache evenly over the poked cake. Use a spatula to help nudge it into every hole for ultimate soakage. Let the remaining ganache blanket the cake in a smooth, silky layer. This is where the “velvety” in Velvety White Chocolate & Blackberry Poke Cake truly comes to life.
Step 5: Make the Blackberry Sauce
Add one cup of fresh blackberries, two tablespoons sugar, and the lemon juice to a small saucepan. Cook over medium heat, stirring frequently, until the berries start to break down and release their juices. When bubbly and soft, pour in the cornstarch-water mixture and stir as the sauce thickens. It only takes a minute—once it coats your spoon, remove from heat and allow to cool slightly.
Step 6: Drizzle the Sauce
Spoon the thickened blackberry sauce evenly over your ganache-topped cake. Spread gently for a gorgeous, jewel-like finish. The contrasting purple-black sauce not only looks stunning, but soaks in just enough for a flavor-packed bite every time.
Step 7: Chill and Garnish
Pop the cake in the fridge for at least an hour so everything melds together and sets up. When ready to serve, garnish generously: crown with fresh blackberries, scatter white chocolate shavings, and if you’re feeling extra, a swirl of whipped cream. Your Velvety White Chocolate & Blackberry Poke Cake is ready for the spotlight!
How to Serve Velvety White Chocolate & Blackberry Poke Cake

Garnishes
Presentation is pure joy with this cake! For that WOW factor, top each slice with a handful of fresh blackberries and a generous shower of white chocolate shavings. A dollop of softly whipped cream puts it over the edge, and even a tiny mint leaf can lend a pop of green for extra elegance.
Side Dishes
This cake is the star—so aim for light, fresh sides. It shines after a simple lunch or dinner, especially alongside coffee, bubbly Prosecco, or a glass of iced berry tea. If you want something creamy, try a scoop of vanilla bean ice cream on the side; the temperature contrast and smoothness are irresistible.
Creative Ways to Present
The Velvety White Chocolate & Blackberry Poke Cake is a showstopper whether served in neat squares, rustic spoonfuls, or cut with a biscuit cutter for beautiful rounds. Mini trifle glasses are fabulous for layering cubes of cake with extra sauce and cream for individual servings—ideal for parties or potlucks.
Make Ahead and Storage
Storing Leftovers
Store any leftovers tightly covered in the refrigerator. Thanks to that moist ganache and berry sauce, the poke cake actually gets even better as those flavors meld overnight—perfect for snacking or a second-day dessert!
Freezing
If you want to make ahead, freeze the cake (without garnishes) once completely cooled and set. Wrap well with plastic wrap and a layer of foil for up to 2 months. For best results, freeze before adding whipped cream or fresh blackberries on top; add these after thawing and before serving.
Reheating
This cake is best enjoyed chilled or at room temperature to preserve the velvety texture. If you do prefer it a touch warmer, allow it to sit at room temp for 15–20 minutes before serving, but avoid microwaving to keep the ganache melt-in-your-mouth smooth and the cake’s structure intact.
