Chocolate Chip Blondies

I'm in search of a low-fat and less calorie dense blonde brownie (or brown brownie, for that matter).

The strategy for this recipe is to start with a can of chick peas, and to mash them in the food processor. Additions of peanut butter, oat flour, vanilla, etc, round out the recipe.

The flavor was ok - peanut butter and vanilla were the dominant flavor unless you got a chocolate chip. And unlike black bean brownies I've tried, the bean flavor was largely hidden. But what didn't work was the texture. These were very mushy. They didn't hold a firm shape, and didn't have the right mouth feel.

I wonder if leaving out the egg and regular flour is what caused the poor texture.
