Preheat the oven to 350 degrees.
In a large bowl, mix together 1 1/4 cup gluten-free baking flour, 1/4 teaspoon salt, 1 tablespoon brown sugar, and 1/2 cup diced, salted butter cubes. Mix together with your hands until the dough gets crumbly.
Add in the ice water, one tablespoon at a time, and mix the dough until you can form a dough ball.
Lightly grease an 8x8 baking dish with butter and press the dough into the bottom, forming an even layer of crust.
Bake the crust for 10-12 minutes. Remove from the oven and set aside. The crust will only be partially baked at this point and that’s okay!
In a saucepan over medium-low heat, melt 4 tablespoons butter, 1 cup maple syrup, 3/4 cup brown sugar, stirring often. Once it’s completely melted together, remove from the heat and add in the beaten eggs, 2 tablespoons gluten-free baking flour and vanilla. Mix well.
Stir in the pecan halves and mix thoroughly. Pour the mixture over the crust.
Return to the oven and bake for 30-40 minutes or until the center is set.
*Remove from the oven and let the bars cool completely before slicing. Enjoy!
*OPTIONAL: If you would like chocolate on your bars, remove them from the oven and add a layer of chocolate chips on top, gently pressing them into the top layer. Place back into the oven for 8-10 more minutes.
