Grease and parchment line a 2-7" cake pans & preheat the oven to 350°F
Prepare the red velvet cake recipe by combining the ground flax seed with hot water & whisk smooth, let stand for 5 minutes to thicken to a paste
In a large bowl place the sifted Flour, Sugar, Baking Soda, Salt & Cocoa Powder together
In another bowl combine all of the wet ingredients & the red food color & whisk smooth
Add the flax paste & then pour all of these wet ingredients into the dry ingredients & whisk smooth for about 25 strokes to develop the batter
Pour the batter into the greased & parchment lined cake pans and bake immediately at 350°F for 25 - 30 minutes or until springy to the touch when gently pressed in the centers or a toothpick comes out with moist crumbs
Once the red velvet cake is cooled take one layer & chop HALF OF IT up into ½" cubes, reserve them in the freezer as these chunks will go into the cheesecake batter later. The rest of that layer will get crumbled up for the garnish of the final cheesecake
The other layer of cake will go into the refrigerator (wrapped well) until after the cheesecake is completely set and ready to assemble
