This Red Velvet Marble Bundt Cake is an impressive and delicious dessert perfect for Valentine's Day. Starting with a vanilla cake mix and enhanced with additional ingredients like sour cream and mayonnaise, this cake is both moist and flavorful. The marbled effect of red velvet and vanilla batters, combined with a drizzle of glaze, makes it a stunning treat to share with loved ones.
Preheat oven to 350 degrees. Grease and flour a 12-cup Bundt pan. (I use a baking spray with flour in it) Set aside.
Place the cake mix, flour, sugar, sour cream, oil, water, mayonnaise, eggs, and vanilla 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.
Place 2 cups of batter to a medium bowl; stir in cocoa powder and food coloring.
Pour a third of the plain batter evenly into the prepared bundt 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 at 350 degrees oven for 50-55 minutes or until a toothpick inserted in middle comes out clean. Allow to cool for 10 minutes in the pan. Invert the cake onto serving dish and allow to cool completely.
In a large bowl, whisk together the icing ingredients together until smooth. Drizzle over the cooled cake. Serves 12.
