ir, my daughter really liked the Betty Crocker cookies. I haven’t made the cakes or brownies yet. They do call for eggs so you would need to substitute for those.
Do you use oats? If so, there is oat matza/ matza meal & oat flour available (Rabbi Kestenbaum). We do use oats because my daughter’s GI said it was all right, & her TTGs (she gets the blood test every 6 months or so) have been fine since a year after her diagnosis.
I’d be most interested in simple recipes/ substitutions or tips about gluten-free (GF) products you’ve tried & liked. I use mixes/ prepared products for most of her food, since the rest of my family is not GF. My daughter really likes Tinkyada brown rice pasta–it doesn’t collapse into a gelatinous mass as many GF pastas do.
We also stock up on non-gebrochts products around pesach time, and I look for pesach items on clearance afterwards. One aspect of pesach that I really love is that it’s the one time of year we can all easily adhere to a GF diet by eating non-Gebrochts (except for matza of course).
