These Low Carb Sugar-Free Keto Sparkling Champagne Cupcakes are the perfect finger food dessert for any party, but especially on New Year’s Eve! Just 2 g net carbs!
According to Cronometer, the app I use, 4 ounces of Prosecco, Sparkling wine, has 2.9 grams of carbs and 83 calories. So it is definitely keto friendly and can be enjoyed.
For our keto sparkling champagne cupcakes, we use 3 ounces for the whole recipe with 12 cupcakes. Each cupcake, not including the buttercream frosting, has 4 grams of total carbs or 2 grams net carbs.
Ingredients:
- 2 eggs
- 1/2 cup unsalted butter (room temperature)
- 1 tsp vanilla extract
- 1 tsp vanilla liquid stevia or see swaps above
- 1/3 cup champagne I used Prosecco
