Creating Cauldron Milk Tea Brownies is a simple process that invites you into the wonderful world of baking:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C) and greasing a 9×13-inch baking pan.
2. Melt Butter: In a saucepan over low heat, melt the butter. Once melted, remove from heat and allow it to cool slightly.
3. Mix Sugars: In a large bowl, combine the granulated sugar and brown sugar. Pour in the melted butter and mix until well combined.
4. Add Eggs and Vanilla: Beat in the eggs one at a time, followed by the vanilla extract, mixing well until smooth.
5. Combine Dry Ingredients: In a separate bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
6. Incorporate Dry Mixture: Gradually add the dry mixture to the wet ingredients, stirring until no lumps remain.
7. Add Milk Tea: Pour in the brewed milk tea and mix until fully incorporated, yielding a smooth batter.
8. Pour into Pan: Pour the brownie batter into the prepared baking pan, smoothing it out evenly.
9. Bake: Place the pan in the preheated oven and bake for 25-30 minutes. A toothpick inserted in the center should come out with a few moist crumbs.
10. Cool: Allow the brownies to cool in the pan for about 10-15 minutes before transferring them to a wire rack to cool completely.
11. Slice and Serve: Once cooled, slice the brownies into squares. Dust with powdered sugar or serve with whipped cream if desired.
