The story is that a baker, trying to make a regular cake batter, accidentally reversed the proportions of flour and butter.

The original was an old-fashioned vanilla pound cake drenched in a butter and sugar syrup which makes the cake really moist. It also results in a crisp coating a bit like a glazed donut.

It’s so good that back in 1963 Nell Lewis entered her Kentucky Butter Cake into the Pillsbury Bake-Off Contest and won!

While the original recipe uses buttermilk, this Kentucky butter cake from Kalie Stephan, The Hungry Elephant, is made with sour cream because buttermilk is too high in carbs for keto.

The sour cream keeps the cake nice and moist. The rest of the ingredients are all keto-approved, such as almond flour, erythritol, and butter.

She’s developed a recipe in place of the original sugar syrup that is keto-friendly using a low carb sweetener.
