8×10 pan 

350 degrees 

16 to 20 minutes 

1/2 cup butter, melted 

1/2 cup cocoa 

1 cup sugar 

2 large eggs 

1/2 to 1 tsp vanilla extract 

2/3 cup flour (I used pastry flour, but all purpose is fine) 

1/2 tsp. baking powder 

1/2 tsp salt (Kosher salt if you have it) 

Melt the butter, either in a saucepan or in a bowl in the microwave. Make sure your pan or bowl is large enough to mix all the ingredients into.

Add in the cocoa, and stir until well blended. Stir in the sugar until fully incorporated. Try eating a few bites because it tastes really yummy. Beat in the eggs until completely mixed. Add vanilla and stir.

Pour the flour on top of the cocoa mixture, sprinkle the salt and baking powder over top. Blend it in to the cocoa/sugar mixture, mixing until well blended. Pour into a greased 8×10 inch pan, and bake in a 350 degree oven for about 17 minutes, 15 or 16 for fudgier brownies, 18 to 20 for more cake like brownies.

Frost with your favourite icing, if you'd like.
