Red Velvet Marble Bundt Cake

I love marble cakes as they satisfy the taste buds of many. I wanted to bake a cake for my dear friend for her birthday. She loved my marble cake before but she likes red velvet. So, I thought of mixing her interests and bake a red velvet marble bundt cake.
She was very happy with both the look of it and the taste, and all the kids loved it. My daughter wants me to bake this cake again for her birthday.
