How to cook deliciously - Triple-Layer Strawberry Cake

1 . Stage

Preheat the oven to 350 degrees F (175 degrees C). Spray three 9-inch cake pans with nonstick cooking spray.

2 . Stage

Mix cake mix, gelatin, eggs, oil, sugar, strawberries, milk, and flour for cake together in a large bowl with an electric mixer on low speed until just combined. Scrape the sides of the bowl, and increase mixer speed to medium; beat for 3 minutes. Pour cake batter evenly into the prepared pans.

3 . Stage

Bake in the preheated oven until a toothpick inserted into the centers comes out clean, about 23 minutes. Cool cakes in pans on a rack for about 10 minutes. Remove from pans and cool completely in the refrigerator.

4 . Stage

Meanwhile, make frosting. Beat butter in a large bowl at medium speed until it's pale yellow and fluffy. Add confectioners' sugar and strawberries and beat at low speed until well combined and creamy. Set in the refrigerator for 5 to 10 minutes to firm it up slightly (you just don't want it to be runny).

5 . Stage

Spread one of the layers of cake with frosting then refrigerate. Frost the second layer and refrigerate until the frosting on both layers has firmed up a bit. Assemble all the layers and frost the top and sides. Refrigerate until ready to serve.
