Method
- Melt butter in a 9x13 baking dish in the preheating oven (350°F).
- Whisk flour, sugar, baking powder, salt, cream of tartar, milk, and vanilla. Pour over melted butter. DO NOT STIR.
- Mix remaining sugars and cinnamon; sprinkle evenly over the batter. DO NOT STIR.
- Gently pour hot water over the entire dish. DO NOT STIR.
- Bake for 35-40 minutes until golden and puffed. Cool slightly and dust with powdered sugar.
Notes
Do not stir the batter after adding the water. The cream of tartar gives it the authentic Snickerdoodle tang.
