Cinnamon Biscuits

Combine flour, baking powder and salt; cut in shortening.
Add milk and 1 tsp. vanilla; stir with fork just until dough leaves sides of bowl.
Roll dough out, on lightly floured surface, into a 1/4 inch thick rectangle.
Brush top with butter (I prefer to use soft butter rather than melted).
Combine cinnamon and sugar; sprinkle evenly over dough.
Sprinkle with chopped pecans (or other nuts or raisins) if desired.
Roll up, starting on long side.
Cut into 1/2 inch thick rounds.
Place rounds, with sides just touching, in greased 9" round pan.
Bake at 425°F for 18-20 minutes or until golden brown.
Remove from oven and drizzle with glaze, serve warm.
For glaze: Combine all ingredients and beat until smooth.
