You will need
3/4 cup soft icing mixture
1/4 cup butter
1 tablespoon flour
1/4 cup cocoa
Somewhere between 1/2 and 1 cup of rolled oats
- Melt the butter in a microwave-safe bowl.
- Mix in all the other ingredients. The salt is absolutely necessary, so this is the point where you make sure you remember it.
- Microwave on high for 1.5 to 3 minutes. Do not let the center get totally dry or it will be overcooked. Take it out when there is still a small moist spot in the center. It finishes cooking as it cools.
This recipe comes out soft, fudgy and awesome. The amount of oats is to taste, but 1/2 a cup seems to be the minimum or else it just ends up a buttery mess. You could probably add more flour instead of the oats, but I like oat brownies.
Since I don't know what it's called everywhere around the world, 'soft icing mixture' is the one that's icing sugar and starch combined.
