  • 1 teaspoon baking powder heaping
  • 3/4 cup butter 176g, unsalted, room temperature
  • 3 egg whites
  • 1/2 cup sour cream room temperature
  • 1/2 cup milk room temperature
  • 2 tablespoons cocoa
  • 6 ounces strawberries sliced, reduced and strained
  • 3 tablespoons lemon juice
For the Buttercreams:
  • 2 tablespoons vanilla extract
  • 3 lb confectioners sugar
  • 1 cup unsalted butter 225g, room temperature
  • ¼ cup cocoa powder
  • 2 tablespoons strained strawberry preserves
  • pink food coloring
  • 1 plash whole milk

Instructions

For the Strawberry Reduction:
    Cup of Yum
  1. Add hulled strawberries and lemon juice to a saucepan over medium heat.
  2. After the mixture heats up for a few minutes, mash the strawberries then allow to simmer for about 10 minutes.
  3. Strain mixture into a bowl. Cover and chill for another 10-15 minutes.
For the Cake:
  1. Sift the dry ingredients together in a large bowl.
  2. Mix the wet ingredients together in a medium bowl.
  3. Add the wet to the dry and mix until just combined.
  4. Divide the mixture into 3 bowls.
  5. Add the cocoa powder to one batch and mix.
  6. Add the 3/4 of the strawberry reduction to the second batch and mix.
  7. Transfer the three batters into three 6″ cake pans, which have been buttered and floured.
  8. Bake at 350 degrees F for about 30 minutes or until the centers are springy to the touch. Let the strawberry layer bake 5-8 minutes longer. Test with a toothpick.
For the Buttercreams:
  1. Whip the butter for about 5 minutes using a paddle attachment (stand-up mixer).
  2. Beat in the confectioner’s sugar slowly.
  3. Add the cream and vanilla. Beat until you have an even, fluffy consistency.
  4. Dive buttercream into 3 parts.
  5. Transfer one vanilla batch to a piping bag and snip off the tip.
  6. For the Chocolate Buttercream:
  7. Mix cocoa into one batch of buttercream.
  8. Transfer to a piping bag and snip off the tip.
  9. For the Strawberry Buttercream:
  10. Add the rest of the strawberry mixture to a buttercream batch.
  11. Add in a few drops of pink food coloring if you want the color to be more vibrant.
  12. Mix together until desired consistency.
  13. Transfer to a piping bag and snip off the tip.
For the Assembly:
  1. Pipe alternating circles between each layer with each buttercream bag.
  2. Add layers
  3. Pipe and smooth out a crumb coat on the outside of the cake with an uneven spatula.
  4. Pipe out petals around the entire cake. Stay consistent with the size of each petal.

Notes

  • The cake layers will all bake for different times, I'll point out that my strawberry layer needed almost 10 minutes longer than the vanilla so keep a close eye out and make sure the centers are set before removing from oven.
  • For the strawberry buttercream, you could add more preserve if you’d like or even use the liquid from defrosted frozen strawberries.
  • If you’re doing a petal design with a crumb coat, it requires A LOT of buttercream. If you're doing a simpler design, you can halve the buttercream.
