Gluten Free Salad Bread Bowls

Try this treat around a nice salad. Yeast and I have big problems working together. Everything I've ever tried to make with yeast has turned out horribly. Most of my breadlike recipes do not use yeast. Advanced options are listed at the bottom.

GF Bread Bowls
1 c Gluten Free Flour (I use a packaged multi purpose GF flour mix)
1/2 c GF Cornstarch
1 tsp Baking Powder
1 tsp Xanthan Gum
1/2 tsp Sea Salt
3/4 c Milk
1/4 c Oil
1/4 tsp Onion Powder
3 Medium sized Metal bowls (just standard 2 cup mixing bowls, nothing special or expensive)
Foil
Cookie Sheet
GF Spray Oil

Preheat oven to 425 degrees. Sift dry ingredients together, add wet ingredients, stir. Knead into a soft ball. Be gentle with it. Separate into 3 balls. Let the dough rest for 5-10 minutes. Line the Cookie Sheet with Foil, then spray oil the foil lightly. Invert your bowls onto the foil covered cookie sheet. Lightly spray some grease onto the outside of your metal bowls. Press dough ball to cover the outside of the bowl. Use your hand to make sure the bottom (now the top) of the bowl remains flat, and try to keep a little extra dough there as well. (That's where all the salad dressing will soak in later)

Bake 10 minutes, until the bread has become a nice golden brown. Let cool. Gently lift the bread off the metal bowls and invert. Tah-Dah! If the bread is overcooked it becomes a little more crumbly.

Advanced Options
Add 1/4 c cheese to the dough, mixing it with the dry ingredients.

Add 2 Tbs parmesan cheese to the dry ingredients and 1 tsp of milk to the wet.

Use a GF Buckwheat Flour Mix instead of a standard GF Flour Mix.
