Hi Wester,
How terrific that you’re involving your kids in baking, you’re building lots of great memories!
Folks here have made some fun suggestions and I thought I’d share a couple of ideas as well.
I make up a basic sugar cookie dough and roll it out into a circle then let the kids top it “pizza-style” with things like nuts, dried fruits, chocolate chips, smarties, gum-drops etc. At parties I’ve let each of the kids flatten their own small round of dough and make individual pizza cookies.
Thumbprint cookies are also fun for kids. Depending on their age, they may enjoy helping to make the small dough balls, and/or rolling the balls into coconut or chopped nuts. Their fingers are the perfect size for making the indentations in the cookies and, they have fun filling them with their favorite jam, jelly or even pb&j.
Happy Baking!
Sue
