Not so Red Velvet Cake

I never grew up with red velvet cake (it just doesn't exist here) so it was never on my to do list. In search for a low carb cake recipe, I found one that should turn out into red velvet cake, but red food coloring just creeps me out. Made without icing, but tastes great with a bit of peanut butter or regular butter.

1/2 cup unsalted butter, melted
1 cup erythritol (about 120 grams)
9 eggs
1/2 cup yogurt (full fat)
1/2 tsp salt
3/4 cup coconut flour, sifted
2 tbsp cocoa powder, sifted
3/4 tsp baking soda

Wisk the eggs in a bowl until frothy. In another bowl, mix the flour, cocoa & salt together.
In a 3rd bowl,  wisk the butter for about 30 seconds, then slowly start adding the erythritol until it becomes a bit of a batter like mix. While mixing again, pour the eggs in.
Then alternate pouring the dry mix and the yogurt in, adding the baking soda last.

Pour it into a cake pan and bake for about 45 mins on 180C (350)
A whole cake weighs about 750 grams, a slice about 50-60 grams, so serves about 12 slices.
Note: Erythritol is a sugar alcohol, with a GI of 0. People respond differently to it, but personally I don't count it as a carb.
