wheat-free chocolate dollar cookies

i was obsessed with the chocolate dollar cookie recipe from the cookie lovers cookie cookbook that i had as a child, and tried altering the recipe to make it gluten free, well, at least wheat free...success!

chocolate dollars


1/2 cup butter
1 cup sugar
1 egg
1 teaspoon vanilla (I use more)
3/4 cup brown rice flower
1/2 cup tapioca flour
1/2 cup potato starch
1/3 cup unsweetened powdered cocoa
1/2 teaspoon baking powder
1/2 teaspoon baking soda

for topping: 
1 tablespoon sugar
sprinkling of sea salt

mix all ingredients. 
the recipe calls for refrigerating the dough, i skip that because i'm too impatient. i just make balls, and press them down, top with some sugar, and this time i tried a little sea salt since the recipe doesn't include salt, and i think it's always nice with dark chocolate. it made a big, delicious difference. 

bake at 325 degrees for 8-10 minutes. they're pretty squishy out of the oven, i often just eat the first one with a spoon!
i searched for years for this cookie cookbook that i used to use as a child, i got it from scholastic news. many thanks to prudence younger for inspiring this recipe!
