Easy Cheeseburger Mini Muffins

Ingredients

• Cooking spray
• 1 pound ground beef
• 1 onion, chopped
• 2 1/2 cups all-purpose flour
• 2 tablespoons white sugar
• 2 teaspoons baking powder
• 1 teaspoon salt
• 3/4 cup milk
• 3/4 cup ketchup
• 1/2 cup butter, melted
• 2 eggs, lightly beaten
• 1 tablespoon yellow mustard
• 2 cups shredded Cheddar cheese

Directions

Preheat oven to 425 degrees F (220 degrees C). Spray 24 mini-muffin cups with cooking spray.

Heat a skillet over medium-high heat. Cook and stir beef and onions in the hot skillet until browned and crumbly, 5 to 7 minutes. Drain excess fat and set aside to cool.

Combine flour, white sugar, baking powder, and salt in a large bowl. Whisk milk, ketchup, melted butter, eggs, and mustard together in a separate bowl; stir into flour mixture until just moistened. Fold ground beef mixture and Cheddar cheese into batter; spoon into each muffin cup.

Bake muffins in preheated oven until a toothpick inserted into the center comes out clean, about 15 minutes.
