Homemade Twinkie Cake Recipe

Make the cake:

1. Preheat the oven to 325º Fahrenheit for dark pans or 350º Fahrenheit for light or glass pans. Spray the bottom of 2 9” square cake pans with cooking spray, then line the pans with parchment paper to ensure the cake comes out cleanly. You can also line the outside of the pans with aluminum foil. This helps the cake layers bake evenly.
2. Mix cake mix, eggs, butter and milk in a large bowl using a mixer on medium speed. Scrape the bowl as needed. Beat for about two minutes. 1 box yellow cake mix, 4 large eggs, 1 cup unsalted butter, 1 ¼ cups 2% milk
3. Divide the batter evenly between the two prepared pans. Bake for 30 minutes or until the center of the cake springs back when you touch it.
4. Allow the cakes to cool in the pan for 5 minutes, then remove them to a wire rack to cool completely.

Make the frosting:

1. In a small saucepan over medium low heat, cook the flour and milk together, whisking constantly, until the mixture thickens to a pudding consistency. 5 tablespoons all purpose flour, 1 cup 2% milk,
2. Remove from the heat and allow the mixture to cool completely. (Move the mixture to another bowl and place it over a bowl of ice for it to cool more quickly.)
3. Using a mixer, cream the butter, shortening, salt and vanilla until smooth. Scrape the sides of the bowl as needed. Add in the sugar and beat for 2 minutes. 1/2 cup shortening, ½ cup unsalted butter, ½ teaspoon salt, 1 teaspoon vanilla extract, 1 cup granulated sugar
4. Add in the cooled flour mixture. Use a mixer and beat until the mixture becomes fluffy like whipped cream. This may take a couple of minutes.

Assemble the cake:

1. If the cakes have domes, use a large knife to level them off so they are somewhat even.
2. Place one cake layer on a plate. Spread all of the whipped frosting over the first cake layer. Then place the second cake layer on top. Dust with powdered sugar. Powdered sugar
