A day or so later we wound up with her making what the book calls something like Aggression Cookies. I forget exactly whether that is what they're called, but the point was that the dry and wet ingredients mushed together make for a lot of fun for a 5-year-old child. Lots of mess and lots of fun and honestly? Lots of yum, too!
Tweaked from The Preschooler's Busy Book:
3 c quick cooking oats
1-1/2 c brown sugar
1-1/2 c flour
1-1/2 c butter or margarine
1-1/2 teaspoons baking powder
Combine all ingredients and let your child go to town. Depending on his/her age, you can allow them to do all aspects of measuring and combining. For me, I did a bit of the measuring just to be sure my entire kitchen floor wasn't covered. But the rest she did on her own.
Mixing it dry
Mixing it wet (and mushy!)
She turned them into little balls and we baked at 350* for about 10 minutes or so - checking them at 8, then 10 and every minute after as needed until you find them ready.
And she did them all by herself - minus the in and out of the oven - of course!
Honestly, I think I ate most of them. So unless you want a ton of cookies hanging around for yourself, be prepared to hand some off to friends and family. Neighbors, even. They're really good, and a sweeter than regular oatmeal cookie - must be the brown sugar.
