Spray a muffin pan with cooking spray and set it aside.

Preheat the oven to 400 degrees.

Make the sloppy joe meat.

In a large skillet over medium-high heat, melt the butter and olive oil together.

Add the beef and cook, breaking apart into fine crumbles as it cooks – about 5 minutes.

Spoon into a fine mesh colander to drain.

Add the onions, bell pepper, and garlic to the skillet. Cook, stirring often, until soft – about 3 minutes.

Add the beef back to the pan and stir to combine with the vegetables.

Stir in the tomato paste, ketchup, broth, brown sugar, mustard, chili powder, Worcestershire sauce, salt, and black pepper. Stir well.

Reduce the heat to medium-low and cook for 15 minutes, stirring often, until you reach the desired thickness. Remove from the heat and set aside.

Separate the biscuit dough into 10 biscuits. 

Flatten each biscuit into a 5-inch circle. Press the dough into the bottom and up the side of the prepared muffin tin.

Fill the center of each muffin with the beef mixture.

Bake in the preheated oven until the biscuits are golden brown – about 10 minutes.

Sprinkle each muffin with the diced cheese cubes.

Return to the oven for 2 minutes longer or until the cheese is melted.

Serve warm.
