    This cake is AMAZING!!! Make it‼️‼️‼️ add some caramel extract/flavoring and some butter flavoring to the batter thank me later 😉

  3. I really like the recipe for gatherings. The only tweak I made was to use dark brown sugar (more for my liking). Otherwise great recipe!

  4. I just made the cake and it’s in the oven right now I’ll let you know after it cools and I’ll make the frosting.

  5. hello, when the recipe says 4 eggs and 2 egg yolks, are you meaning a total of 6 eggs or just the yolk of the 4 added separately (Add the eggs and yolks one at a time). thanks, I love caramel cake prepared in every way.

  6. Tried this after my husband and I loved your Turkey tetrizinni last night. Cake and icing turned out very well. Thanks for the post!
