Cut biscuits into quarters and place them in a bowl. In a separate bowl, mix sugar, ½ cup brown sugar and cinnamon. Pour cinnamon-sugar mixture over biscuits, seal bowl and shake together to coat biscuits. Place Cone in 3-Qt./3 L Casserole and add biscuits around it.

In the Cover, melt butter and the remaining brown sugar on high power 30–45 seconds, then pour it over the biscuits. Cover and microwave on high power about 12 minutes. Let stand at least 5 minutes before inverting onto Cover and serving.
