1Heat oven to 350°F. In 10-inch skillet, cook beef over medium-high heat 5 to 7 minutes, stirring frequently, until brown; drain. Stir in chili powder. Stir in hot water and milk, sauce mix and uncooked pasta (from Hamburger Helper box). Heat to boiling, stirring occasionally. Reduce heat; cover and simmer 14 minutes, stirring occasionally. Remove from heat; uncover. Stir in 1/2 cup of the cheese.
2Separate dough into 8 biscuits. Press or roll each to form 5 1/2-inch round. Firmly press 1 biscuit in bottom and up side of each of 8 ungreased jumbo muffin cups, forming 1/4-inch rim. Fill with macaroni mixture; sprinkle with remaining cheese.
3Bake 20 to 25 minutes or until golden brown. Cool 1 minute. Loosen edges with knife; remove from muffin cups.
