PREHEAT the oven to 350F.
LINE 10 cups of a cupcake pan with cupcake papers and set aside.
WHISK the eggs briefly in a large mixing bowl, then stir in the oil and vanilla, then the champagne. Mix just until combined after each addition. Do not overmix.
ADD the coconut sugar and cake mix and stir vigorously until combined.
PORTION the cupcakes into the compartments of the prepared pan using an ice cream scoop.
BAKE for 14-16 minutes or until a tester comes out clean.
COOL completely before frosting and/or serving (with a few flutes of Champagne to have your own Simple Celebration, of course!)
