Summer Berry Poke Cake (Printable)

Moist vanilla cake layered with mixed summer berries and whipped cream topping

# What You'll Need:

→ Cake Base

01 - 1 box (15.25 oz) vanilla or white cake mix with required eggs, oil, and water

→ Berry Sauce

02 - 2 cups mixed summer berries (strawberries, blueberries, raspberries, blackberries)
03 - 1/2 cup granulated sugar
04 - 1/2 cup water
05 - 2 tablespoons lemon juice
06 - 2 tablespoons cornstarch mixed with 2 tablespoons cold water

→ Whipped Topping

07 - 2 cups heavy whipping cream
08 - 1/4 cup powdered sugar
09 - 1 teaspoon vanilla extract
10 - 1 cup fresh mixed berries for garnish
11 - Fresh mint leaves (optional)

# How to Make It:

01 - Prepare the vanilla cake mix according to package instructions, incorporating the required eggs, oil, and water. Pour batter into a 9x13-inch baking dish and bake as directed. Remove from oven and allow to cool for 15 minutes.
02 - Using the handle end of a wooden spoon, press holes into the partially cooled cake at approximately 1-inch intervals across the entire surface. This creates channels for the berry sauce to penetrate.
03 - Combine mixed berries, granulated sugar, water, and lemon juice in a saucepan over medium heat. Bring to a gentle simmer. Whisk cornstarch with cold water until smooth, then stir into the berry mixture. Continue cooking for 2-3 minutes while stirring constantly until the sauce thickens noticeably.
04 - For a smoother texture, press the berry sauce through a fine-mesh sieve to remove seeds. Pour the warm strained sauce evenly over the entire cake surface, ensuring it fills the poke holes completely.
05 - Allow the cake to cool completely to room temperature, then refrigerate for a minimum of 1 hour. This chilling period lets the berry mixture fully absorb into the cake structure.
06 - Using an electric mixer, beat the heavy whipping cream on medium-high speed until soft peaks form. Add powdered sugar and vanilla extract, continuing to beat until stiff peaks are achieved and the cream holds its shape firmly.
07 - Spread the prepared whipped cream evenly over the chilled cake surface. Arrange fresh mixed berries attractively across the top and garnish with mint leaves if desired. Serve immediately or keep refrigerated until serving time.

# Expert Hacks:

01 -
  • It transforms a simple box cake into something that tastes homemade and special
  • The berry soaked pockets create pockets of intense fruit flavor in every bite
  • You can make it ahead and keep it in the fridge until you are ready to serve
02 -
  • Poke the holes while the cake is still warm so the sauce really penetrates the crumb
  • Let the sauce cool slightly before pouring so it does not make the cake soggy
  • The assembled cake keeps beautifully in the fridge for up to two days
03 -
  • Room temperature berries release more juice so let them sit out while you bake the cake
  • A splash of almond extract in the whipped cream makes everything taste more complex
  • If your sauce seems too thick add water one tablespoon at a time until it pours easily
