Red Velvet Sheet w/ Classic Frosting****

By Gigirox

I was so glad to find a red velvet with this frosting, It's just not the same with the cream cheese frosting.

Ingredients

• Ingredients Sheet Cake:
• Nonstick baking spray
• 2 1/2 cups cake flour
• 1 teaspoon salt
• 1 cup buttermilk
• 1 teaspoon vanilla extract
• 1 teaspoon baking soda
• 2 whole eggs
• 1 1/2 teaspoons vinegar
• 1 1/2 teaspoons cocoa powder
• 1 1/2 fluid ounces red food coloring
• 1 cup shortening
• 1 3/4 cup granulated sugar
• Classic Red Velvet Frosting:
• 1 cup whole milk
• 5 tablespoons all-purpose flour
• 1 teaspoon vanilla extract
• 2 sticks unsalted butter
• 1 cup granulated sugar

Preparation

Step 1

Directions:
-Preheat the oven to 350 degrees F.
-Thoroughly spray a large (18-by-12-inch) sheet cake pan (or you can use a slightly smaller jelly roll pan) with nonstick baking spray. Be sure to get in all the corners of the pan.
-Sift together the cake flour and salt. Set aside.
-In a separate bowl, stir together the buttermilk, vanilla, baking soda and eggs. Add the vinegar and stir. Set aside.
-In a separate small bowl, mix together the cocoa and red food coloring. Set aside.
-Cream together the shortening and sugar until fluffy.
-Alternate adding the flour mixture and the buttermilk/egg mixture until all combined.
-Pour in the red mixture and beat until combined.
-Pour the batter into the prepared sheet cake pan. Use a large offset spatula or knife to even out the surface.
-Bake for 20 minutes.
-Remove the pan from the oven and allow the cake to cool completely before frosting.
Directions for Frosting:
-Combine the milk and flour in a saucepan over medium heat and whisk constantly until thick.
-Remove from the heat and let cool to room temperature.
-Add the vanilla once cooled.
-In the bowl of a stand mixer with the paddle attachment, cream the butter and sugar until light and fluffy.
-Add the cooled milk mixture and beat very well. It may look separated, which means you have to keep beating until fully combined.
-It should be fluffy and light, similar to whipped cream.
