Preheat oven to 350. Line a 12-cup muffin tin with liners.
Cut each biscuit into 6 pieces, starting by cutting each biscuit in half and from there, each half into three pieces.
Roll each piece into a ball.
In a small bowl, mix sugar and cinnamon together. Roll each piece of dough in the cinnamon sugar mixture.
Place sugared dough into the muffin cups; 4 per cup.
In a small saucepan, combine butter, brown sugar, milk, and vanilla extract. Once all ingredients are combined, bring to a boil. As soon as it's boiling, take it off the heat.
*Spoon a little of the sauce over each muffin cup, repeating until you are out of sauce.
Bake for 12-15 minutes, or until biscuits are golden brown.
Best when served warm :-)
