Melt the butter and chocolate in the same bowl in the microwave. Be careful not to burn the chocolate (stir with the spatula every 15 seconds)

Whisk the sugar and eggs together nicely in a large bowl.

Add in the melted butter and chocolate from Step 1 into the same bowl and whisk 2-3 times.

Now add in the flour and cocoa powder and whisk till it all mixes well.

Grease a small rectangular pan with a tsp of butter and pour in the mixture.

Pre-heat the oven to 375°F. Bake in the pre- heated oven for 20-22 minutes
