I can’t remember the last time I went to an old fashioned bake sale. They feel like that now, old fashioned. I remember when we were kids and we had them all the time for schools to raise money. I do love to buy an occasional baked good at the Farmer’s Market though.

Can’t wait to make these for the grandkids. I missed their first day of school and like to take them “celebration cookies” for these big occasions. As for the question, “How do you stay so slim?” I have a dear friend who bakes almost non-stop and is very thin. I know she likes to eat her own goodies, but her metabolism must be over the moon, because she never gains an ounce! I, on the other hand, gain ounces simply by looking at your pictures and reading the recipes! Oh well….
Thanks

Presentation is right next door to everything, isn’t it? Yours look beautiful. You asked about bake sale recipes…here’s one that I used to make for bake sale at my kids’ school:
Oatmeal Coconut Cookies
1 c. shortning
1 c. granulated sugar (I’ve been known to use Splenda.)
1 c. brown sugar
2 large eggs
2 tsp. vanilla
3 cups oats
1 1/2 c. flour
1 tsp. salt
1 tsp. soda
1 tsp. cinnamon (I’ve also added 1 tsp. cloves, too.)
1 1/2 c. coconut
1 c. coarsely chopped macademia nuts (or walnuts)
I cream the shortning and sugars and then add eggs.
Add dry ingredients and mix well. Standard cookie mixing technique.
I use an ice cream scoop and a Silpat pad on pan…makes 3+ dozen big cookies.
Bake at 350 degrees for 8 – 10 minutes, depending on size. Cool for 2-3 minutes on pan before removing to cooling rack.

My daughter and I just finished a double batch of these so we have enough for her kindergarten class and my sons third grade class to all share tomorrow at school!
Sallie says
I have this same recipe but always mix the M and M’s in the batter. It looks so much prettier with them pressed on top. I’ll have to do that next time.
