Beignet Recipe (Ready in 10 minutes or less!)

Because Mardi Gras is such a fun holiday with a very famous delicious treat, we will share how we make them at home so you have a snack while you go through the tutorial! Reference link: here


  • Store bought pizza dough (can be the one in a can like Pillsbury!)
  • Powdered sugar
  • Cooking oil


  • In a saucepan, heat 2 inches of oil to 350 degrees F
  • Set a plate to the side with a paper towel on it
  • Flour the pizza dough, roll it into a ball and cut small rectables about .5 inch thick
  • Fry 2–3 minutes at a time until deep golden brown
  • Let excess oil soak into the paper towel
  • Top with powdered sugar (if you want to go all in, carefully toss the hot beignets into a paper bag full of powdered sugar to get them REALLY coated!)
