Today I discovered two gluten free mixes in our local Trader Joe's (in California) I had not seen before.
One was a gluten free brownie mix.

And the other one was a gluten free pancake mix.

I have not tried these yet because our pantry is already full of
GF baking supplies from Bob's Red Mill. I did look at the ingredients on the pancake mix and it is vegan as well as gluten free.
Woo Hoo!
