This recipe is one of the first treats my mom made and sent me after I went gluten free, and it's still one of my favorites.
These bars are gooey with a good flavor (and super easy to make).
My mom found the original recipe on celiac.com. Here's my version:
1/2 cup butter
2 cups packed brown sugar
1 teaspoon vanilla
1 1/2 cups gluten-free flour (I used a mix of sorghum, rice and tapioca)
3/4 teaspoon xanthan gum
2 teaspoons baking powder
1/2 teaspoon salt
2 cups of some combination of chopped dates, chopped nuts, chocolate chips, butterscotch chips or white chocolate chips (I used 1 cup each of dates and white chips)
Preheat over to 350.
Cream margarine and brown sugar together. Add eggs and vanilla and beat until light.
Combine flour, xanthan gum, baking powder and salt. Mix well.
Add the flour mixture to the egg/butter/sugar mixture and blend at low speed.
Stir in dates/nuts/chips.
Spread batter into a greased 9-by-13-inch pan.
Bake for 25 to 30 minutes. Cool before cutting into bars.
