Cut each biscuit into 6 pieces; place in large bowl. Add butter, apple, sugar and cinnamon; toss gently to mix. Your hands work well here as the biscuits tend to stick together.
Spoon mixture into lined muffin cups.
Bake for 20-25 minutes or until golden brown. Immediately remove from pan and cool.
For topping, in a small saucepan, heat brown sugar and cream to a boil over medium heat, stirring constantly. Remove from heat and beat in powdered sugar until smooth. Drizzle over biscuit cups.
