Keto Red Velvet Cake

I have made a wonderful keto red velvet cake that I have adapted to keto. This was Michael’s grandmother’s recipe, so I wanted to make it for him for his birthday. This is one of the cakes that Michael’s grandmother always used to make and I was able to write down from her before she passed. Whenever I make this I just know that it will remind Michael of his childhood when his grandma would make this cake for him and remind me of the time I spent with his grandmother.

To Color Or Not To Color. That is the question.

You can certainly do this cake without any food coloring at all or you could add red velvet emulsion to add to the flavor of this cake, but it will not change the color much. To get the classic red color you do have to add food coloring. Michael’s grandmother’s recipe called for 2 oz of food coloring, but I only added 1 oz and it seems to be red enough… I think so anyway.

This is a rich and dense cake with light frosting that will satisfy your craving for cake while staying on track. Eating healthy has never tasted so sweet. I frost this with our cream cheese frosting , but you could frost it with buttercream frosting if you would rather. Either way would be delicious.

We also have a great Boston Cream Pie recipe.
