Measure warm water into a glass measuring cup or bowl. Stir in yeast and sugar, allow to stand for 10 minutes – it should get very bubbly.
In a large mixing bowl, combine Caputo gluten free flour, 1 tablespoon olive oil, salt, and baking powder. Pour in yeast mixture, stir well to combine.
Dump dough out onto a floured surface, knead until soft and smooth, about 3-5 minutes. (Alternatively, knead together by hand, then use a stand mixer with a dough hook for about 3 minutes, or until dough is smooth).
If the dough isn’t a little sticky, add up to1 tablespoon of water, and knead it in. You want the dough smooth, but just very slightly sticky.
Once dough is fully kneaded, swirl remaining 2 tablespoon Olive Oil in a nonstick 9 x 13" pan.
Press dough evenly across the bottom of the pan. Lightly spray the top of the dough with cooking spray, cover pan with plastic wrap.
Transfer to the fridge and allow to rise overnight.
