Ingredients

Cake:

  • 1 box white cake mix
  • 1 (3-ounce) box strawberry jello
  • 3 large eggs
  • 1/4 cup granulated sugar
  • 1/4 cup milk
  • 3/4 cup vegetable oil
  • 1 cup fresh strawberries, chopped

Strawberry Buttercream:

  • 1 cup butter, softened
  • 3-4 cups confectioners sugar
  • 1 teaspoon vanilla
  • 1 cup fresh strawberries, cupped and drained if super juicy

Garnish:

  • strawberries

Instructions

  • Preheat oven to 350°F (177°C). Spray a 9X13 inch baking dish with nonstick cooking spray; set aside.
  • In a large mixing bowl, add all the ingredients for the cake, except the chopped strawberries. Using a handheld electric mixer, set it on low, and mix until all ingredients are combined. Increase the mixer to medium and continue to mix for 3 minutes. Fold in chopped strawberries (1 cup) until evenly distributed.

  • Pour batter into prepared baking and bake until a toothpick inserted into the center of the cake comes out clean, about 30-35 minutes. Let cake cool completely.
  • While the cake is cooling, make the frosting. In a medium mixing bowl, beat butter (1 cup) on medium until light and fluffy, about 2 minutes. Add 3 cups powdered sugar, adding more confectioners sugar as needed to create the desired texture. Add vanilla (1 teaspoon) and chopped strawberries (1 cup) and fold until evenly combined

Notes

  1. White cake Mix: The box mix is used as an ingredient only. You do not add the ingredients on the back of the box. I like the white cake mix the best because I think it creates the prettiest color.
  2. Jello: Just like the cake mix, jello is used as an ingredient. You add it to the mix dry, not prepared.
  3. Strawberries: All fresh strawberries are not created equally. Some are on the drier side, while some are incredibly juicy. If your strawberries are juicy then I suggest you dry them off a little bit with paper towels.
    • After you chop them,  just spread them out on a double layer of paper towels then top with another double layer for a few minutes. They can add too much moisture to the cake and frosting.
