Ingredients
Method
- Preheat oven to 350°F (175°C) and butter a 9x9 inch square pan. Whisk flour, sugar, baking powder, and salt in a large bowl. In another bowl, mix ½ cup melted butter, milk, eggs, and 2 tsp vanilla. Stir wet into dry just until combined.
- Mix brown sugar, cinnamon, and 2 tbsp melted butter into a paste. Spread batter in the pan, drizzle the cinnamon mixture over it, and swirl with a knife for about 10 seconds.
- Bake 35–40 minutes until a toothpick inserted near the center comes out with moist crumbs. Cool in the pan 15 minutes.
- Whisk powdered sugar, 2 tbsp milk or cream, and ½ tsp vanilla into a smooth glaze. Drizzle over the warm cake, slice into 9 squares, and serve.
Notes
Let the cake rest for at least 15 minutes out of the oven before glazing so the warmth sets the glaze without melting it completely. If you bake in a glass pan, the edges may brown a bit faster; check 5 minutes before the suggested time.
