Creating these delicious Vietnamese Coffee Brownies is straightforward. Just follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and line a 9×13 inch baking pan with parchment paper for easy removal.

2. Melt the Butter: In a medium saucepan, melt the unsalted butter over low heat. Remove from heat once melted and let cool slightly.

3. Mix Sugars and Eggs: In a large bowl, combine the granulated sugar and brown sugar with the melted butter. Stir well to combine. Add the eggs, one at a time, mixing well after each addition. Add in the vanilla extract.

4. Combine Dry Ingredients: In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt.

5. Add Coffee and Condensed Milk: Gradually fold the dry ingredients into the wet mixture. Then, stir in the brewed coffee and sweetened condensed milk until smooth.

6. Pour Batter into the Pan: Pour the brownie batter into the prepared baking pan, smoothing the top with a spatula. If desired, sprinkle chocolate chips on top for extra richness.

7. Bake: Bake in the preheated oven for 30-35 minutes or until a toothpick inserted in the center comes out with a few moist crumbs. Be careful not to overbake to keep those fudgy textures.

8. Cool and Slice: Allow the brownies to cool in the pan for about 15-20 minutes before lifting out using the parchment paper. Let them cool completely on a wire rack before slicing into squares.
