You can use 1/4 teaspoon xanthan gum in place of the chia seed, or leave it out altogether for a slightly less cohesive blondie (not an issue if you plan to scoop the blondie out of the pan).
If gluten isn't an issue for you or your guests, you can probably trade all-purpose or whole wheat pastry flour (or rye flour!) for the total amount of flours here and omit the chia seed.
Serve this warm from the oven scooped into bowls, or let it cool a bit more and cut into wedges. For square bars, bake in an 8" pan, cool completely, and cut into 12-16 squares.
