Activate Yeast: Start by dissolving the yeast and sugar in warm water. Let it sit for 5-10 minutes until it foams up.

Prepare Dough: In a large bowl, whisk together buttermilk, egg, and melted butter. Gradually mix in the flour until a soft dough forms.

First Rise: Transfer the dough into a greased bowl, cover with a towel, and let rise until doubled, about 1 hour.

Roll Out: Roll the dough to about ½-inch thickness. Cut into 2-inch squares.

Fry: Heat oil to 350°F and fry squares for 1-2 minutes per side until golden brown.

Glaze: Dip warm beignets into the glaze and let set on a cooling rack.
