*I made the oat flour at home by grinding gluten-free rolled oats in my blender.
Preheat the oven to 350F and line a baking sheet with parchment paper. In a large bowl, combine flour, sugar, chia eggs, oil, vanilla and salt, and stir well to create a uniform dough. Fold in the chocolate chips, then scoop the dough onto the lined baking sheet, leaving about 1 1/2-inches of space between the cookies. Gently flatten the dough with your fingers, as these cookies won't spread too much with baking.
Bake for 10-12 minutes at 350F, until the cookies are lightly golden and the edges are firm. Cool on the pan for 5 minutes, then transfer the cookies to a wire rack to cool completely.
