Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 350°F (175°C).
Line an 8×8-inch baking pan with parchment paper or lightly grease it.
This helps prevent the brownies from sticking.
2. Mix the Wet Ingredients
In a large bowl, combine the melted butter and sugar.
Stir until the mixture looks smooth.
Add the eggs and vanilla extract.
Mix until everything is fully combined.
Small tip: Mixing the eggs well helps create a smooth brownie texture.
3. Combine the Dry Ingredients
In a separate bowl, mix together:
- Flour
- Cocoa powder
- Salt
- Baking powder
Stir until evenly combined.
4. Make the Brownie Batter
Slowly add the dry ingredients to the wet mixture.
Stir gently until a thick brownie batter forms.
Avoid overmixing.
Small tip: Overmixing can make brownies less soft.
5. Pour the Batter into the Pan
Pour the batter into the prepared baking pan.
Use a spatula to spread it evenly.
6. Bake the Brownies
Place the pan in the oven.
Bake for 20–25 minutes.
The edges should be set while the center remains slightly soft.
7. Add the Marshmallows
Remove the brownies from the oven.
Sprinkle the mini marshmallows evenly over the top.
Add chocolate chips if using.
8. Bake Again
Return the pan to the oven.
Bake for another 5 minutes until the marshmallows become soft and slightly golden.
9. Cool the Brownies
Remove the pan from the oven.
Allow the brownies to cool for at least 15 minutes.
This helps them firm up for easier slicing.
10. Slice and Serve
Cut the brownies into squares.
Serve them warm or at room temperature.

Chopped walnuts or pecans add a crunchy texture.
