Step 1

Preheat oven to 350 degrees. Hull strawberries then dice into pieces about 1/2 inch in size.

Step 2

Whisk flour, baking powder, and sea salt together in a large bowl then add strawberries and dredge in the dry mixture to coat. Set aside.

Step 3

In another bowl, mix together eggs, sugar, butter, champagne, and vanilla extract. Add this wet mixture to the bowl of dry mixture and stir until just combined and no lumps or dry pockets exist. Batter will be thick and sticky.

Step 4

Convey batter into a piping bag or zip-top bag with one corner snipped off and pipe into donut tin.

Step 5

Bake in oven for about 18 minutes or until donuts are risen and firm. Tops will not brown. Stick a toothpick through one donut near the middle of the pan to see if it comes out clean, if necessary.

Step 6

While donuts bake, whisk together powdered sugar and champagne to form the champagne donut glaze.

Step 7

Once donuts have cooled, dip each one, face down, into the glaze. Sprinkle sugar sprinkles over top, if desired.
