Melt butter in a large dish in microwave, then stir in vanilla.
Pop open biscuits break into pieces and toss into bag with sugar. Zip bag closed ever so often and toss dough pieces around, so every piece is covered with sugar.
Pour dough pieces and sugar into a nonstick tube or bundt pan. Make sure dough is evenly distributed around the pan. Drizzle melted butter and vanilla evenly over the dough. Place in oven and bake for 30 minutes. Remove and let set for 5 minutes before inverting onto a large plate or platter.
