Ingredients
  

  • 🍓 Ingredients
  • For the Cake
  • 1 15.25 oz white cake mix (ignore the box directions completely)
  • 1 3 oz packet strawberry gelatin powder (use dry, do not prepare it)
  • 3 tablespoons granulated sugar
  • 3 tablespoons all-purpose flour
  • 1 cup water
  • ½ cup canola or vegetable oil
  • 2 large eggs at room temperature
  • 1 cup finely diced strawberries fresh or frozen
  • For the Strawberry Frosting
  • ½ cup unsalted butter softened
  • ½ cup strawberry puree blend fresh or slightly thawed frozen berries
  • 4½ to 5 cups powdered sugar sifted
  • Optional: whole strawberries sliced berries, or chocolate-dipped strawberries for garnish

Method
 

1. Prepare the Pans

Heat your oven to 350°F. Coat two 8-inch round pans with grease and line the bottoms with parchment paper for easy release.

    2. Mix the Batter

    In a large mixing bowl, combine the dry cake mix, strawberry gelatin powder, sugar, and flour. Stir until evenly blended. In a separate bowl, whisk together the water, oil, and eggs. Pour the wet mixture into the dry ingredients and beat on medium speed for about 2 minutes until smooth and fully incorporated. Carefully fold in the chopped strawberries.

      3. Bake

      Divide the batter evenly between the prepared pans. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean. Let the cakes rest in the pans for 5–10 minutes before transferring them to a wire rack. Cool completely before frosting.

        4. Make the Frosting

        Whip the softened butter until creamy and pale. Blend in the strawberry puree until smooth. Mix in 3 cups of powdered sugar. Continue adding more sugar gradually until the frosting reaches a fluffy, spreadable consistency. For thicker frosting (great for piping), add extra powdered sugar one tablespoon at a time. If it becomes too stiff, mix in a small splash of milk to loosen it.

          5. Assemble the Cake

          Spread about ¾ cup of frosting between the layers. Use the remaining frosting to cover the top and sides.

          Pro Tip: Apply a thin crumb coat first, chill briefly, then add the final layer of frosting for a clean, bakery-style finish.

            Notes
