Swirls of classic yellow cake and red velvet cake batter gently scooped into a greased bundt pan to create a beautiful marble pattern that's perfect for the holidays.
Preheat oven to 350°F. Grease and flour a 12-cup Bundt pan. (I use Crisco and lots of it.) Set aside.
Place all ingredients in a large bowl. Mix on low with an electric mixer until ingredients are combined, then turn up the speed to medium and beat for two minutes. Transfer 2 cups of batter to a medium bowl; stir in cocoa and food coloring.
Pour a third of the plain batter evenly into the prepared pan. Gently scoop in half of the red batter on top, distributing evenly. Use a spatula to smooth slightly. Continue layering batters in pan as directed above until all batter is used.
Bake in preheated oven for 50-55 minutes or until a toothpick inserted in middle comes out clean. Let cool completely, about 1 hour. Remove from pan onto serving platter and drizzle with vanilla glaze (instructions follow).
For the vanilla glaze
In a large bowl, whisk together the powdered sugar, milk and vanilla until smooth.
