Microwave berry crisp

Last night was nice and cool (and rainy! The best thing that could happen), but I didn't want to turn on the oven to make dessert. So I googled microwave berry desserts and got the idea for this.

Crisp for two:
Cover the bottom of two small bowls with berries (I used blueberries and raspberries). Mix together about 1 tablespoon cold butter, 1 tablespoon sugar, 1 teaspoon flour, and 2 tablespoons of oats. Pour it over the berries and pop in the microwave for a minute and a half. And viola! Dessert in less than five minutes. (Although "crisp" is a bit of a misnomer, because it won't be.)

It's very good with ice cream on top, too.
