“Birthday cake” can be an intimidating pair of words: The pressure to create a showstopper feels baked into them. However, that doesn’t have to be the case. With this recipe, you simply tinker with store-bought chocolate cake mix to create a taller-than-average cake that you cut in half across the middle rather than having to bake two separate layers. While the cake bakes, stir together an easy strawberry buttercream to tie this decadent summery treat together.

Substitution Tip: Don’t have fresh strawberries? Frozen work, too. Just microwave for 30 seconds and then mash with a fork.

Step-by-step instruction without your screen going to sleep

  • 3 3/4 cups water, divided
  • Nonstick cooking spray
  • 4 tablespoons all-purpose flour, divided
  • 1 (16-ounce) box chocolate cake mix
  • 2 large eggs plus 2 egg whites
  • 1/2 cup canola oil or vegetable oil
  • 3 sticks (11/2 cups) unsalted butter, at room temperature
  • 4 cups powdered sugar
  • 1 teaspoon pure vanilla extract
  • 2 cups very ripe strawberries, stemmed and smashed with a fork


  • 2 Large Bowls
  • Stand or Hand Mixer
  • Step 1

    Pour 3 cups of water into the pot. Spray the bottom of the Multi-Purpose Pan with cooking spray and dust with2 tablespoons of flour.

  • Step 2

    Combine the cake mix and the remaining 2 tablespoons of flour in a large bowl and mix thoroughly. In a separate large bowl, stir together the eggs and egg whites, the remaining 3/4 cup of water, and the oil until combined.

  • Step 3

    Slowly add the dry ingredients to the wet and stir just until combined. Pour the batter into the prepared pan.

  • Step 4

    Place the pan on the bottom layer of the Deluxe Reversible Rack in the lower position, then place the rack in the pot.

  • Step 5

    Close the lid and move the slider to STEAMCRISP. Select STEAM & BAKE, set the temperature to 285°F, and set the time to 25 minutes. Press START/STOP to begin cooking (PrE will display for about 20 minutes as the unit steams, then the timer will start counting down).

  • Step 6

    While the cake is baking, prepare the frosting. Put the butter in a large bowl. Using a hand or stand mixer on medium speed, cream the butter on high speed for 30 seconds. Gradually add the powdered sugar and vanilla. Once the frosting has come together, beat in the strawberries.

  • Step 7

    When cooking is complete, check for doneness by inserting a wooden toothpick into the middle of the cake. If it comes out clean, remove the rack with the pan. If the toothpick comes out with moist crumbs stuck to it, bake for 5 more minutes or until the toothpick comes out clean

  • Step 8

    Remove the pan from the pot. Rest the pan on the counter and let cool for at least 1 hour.

  • Step 9

    Once the cake has cooled, flip the cake onto a plate, and use a serrated knife to slice it in half horizontally to create two layers. Place the bottom cake layer on a plate, cut-side up, and evenly cover with half the frosting. Placethe second layer on top of the first, cut-side down, and frost the top and sides of the cake. Serve and enjoy.
