Prepare Ingredients: Begin by gathering all your ingredients for the Buttermilk Beignets. Measure out the all-purpose flour, sugars, baking powder, baking soda, salt, nutmeg, buttermilk, eggs, vanilla extract, and melted butter.

Mix Dry Ingredients: In a large mixing bowl, combine the all-purpose flour, granulated sugar, baking powder, baking soda, salt, and ground nutmeg. Whisk these dry ingredients together until well blended.

Combine Wet Ingredients: In another bowl, whisk together the buttermilk, eggs, vanilla extract, and warm melted unsalted butter until fully combined.

Mix Together: Gently fold the wet ingredients into the dry mixture until just combined. Be careful not to overmix.

Rest Batter: Set your batter aside for about 10 to 15 minutes to allow the leavening agents to activate.

Heat Oil: In a deep, heavy pot, heat vegetable oil to 350°F (175°C).

Fry Beignets: Drop spoonfuls of the batter into the hot oil, frying for approximately 2 to 3 minutes on each side.

Drain Oil: Use a slotted spoon to remove the beignets from the oil and place them on a plate lined with paper towels.

Dust with Sugar: While still warm, generously sprinkle powdered sugar over the beignets.

Serve: Serve your freshly made Buttermilk Beignets immediately for the best taste and texture.
