In a small bowl, combine the active dry yeast and warm water. Let it sit for about 5 minutes until foamy and activated.

In a large mixing bowl, whisk together buttermilk, sugar, melted butter, egg, and salt. Add the yeast mixture and stir well. Gradually add flour, mixing until a soft dough forms. The dough will be slightly sticky, which is normal.

Cover the bowl with plastic wrap or a clean towel. Let the dough rise in a warm place for 1 to 1.5 hours, or until doubled in size.

Lightly flour your work surface and roll the dough to about 1/4 inch thickness. Cut into 2-inch squares using a sharp knife or pizza cutter.

Pour vegetable oil into a heavy-bottomed pot to about 2 inches deep. Heat oil to 350°F (175°C).

Carefully fry 3–4 beignets at a time for about 1 minute per side, until golden brown and puffed.

Remove and drain on paper towels.

In a bowl, whisk powdered sugar, buttermilk, and vanilla extract until smooth. Dip slightly warm beignets into the glaze or drizzle over the top. Allow glaze to set for a few minutes before serving.

These Easy Glazed Buttermilk Beignets are best enjoyed warm and fresh.
