Chocolate Brownies

I want to share with you guys this recipe. It's from an aunty. Hope you guys know how to bake?  

Chocolate Brownie Cake:

Grease (use butter) and flour on an 8 inch square pan.
Heat up oven to 350 degrees farenheit (175 degrees Celsius) .
In a sauce pan, melt ½ cup butter .
Once melted, add in 1 cup sugar, 2 eggs, 1 tsp. vanilla extract .
Beat in 1/3 cup cocoa powder, ½ cup flour, ¼ tsp. salt, ¼ tsp. baking powder.
Pour into your prepared pan.
Bake for 25-30 mins. Don’t overbake.
When done, take immediately out of oven and let cool down.
If you don’t, a turned off oven means the cake will continue to bake in the leftover heat and that will mean the ends might be overcooked.
I find doubling the recipe helps as this cake is so delicious that you can make more and there still won’t be enough for family and friends to eat…hahaha.
You can also put less sugar in and more cocoa powder (by only a few tablespoons) otherwise the cake will taste bitter due to the cocoa powder.
Happy and blessed baking!
