15 batches of cookies

I gave them these little houses for their birthday and they love them. Each one is different and each one has different furniture. I got them at a yard sale for $3.00 each. Great bargain I thought. They carry these little houses everywhere they go. Anyway, now they are fighting over who gets what furniture. They all wanted an oven. So I thought I was being smart. I got on the internet, looked up a picture of an oven and printed it and made an oven out of a little card board box. Good Grief the fighting never stops here. Next they wanted cookies to put in the oven. So I made 15 batches of cookies for their ovens (pictures on cardboard).
