Prepare frozen biscuits according to package directions.
Meanwhile, melt butter in large skillet over medium-high heat. Add ham, and cook 3 minutes on each side or until lightly browned; remove ham.
Add flour to skillet; cook, whisking constantly, 1 minute. Add brewed coffee, brown sugar, and 1/2 cup water. Cook, whisking constantly, 3 minutes or until thickened; return ham slices to skillet. Stir in salt, pepper, and, if desired, hot sauce.
Split warm biscuits in half. Top bottom halves with ham slices. Pour gravy over ham; cover with remaining biscuit halves. Serve immediately.
Note: For testing purposes only, we used White Lily Southern Style and Buttermilk Frozen Biscuit Dough.
