I'm new to Steemit, but I just posted a close to keto smoothie recipe today, https://steemit.com/recipe/@ariadne.spiral/antioxidant-probiotic-powerhouse-smoothie . I was pretty strictly keto for 4 years and it still informs the way I eat. I love to bake and I got pretty good at creating keto treats that even my non-keto friends love. I plan on posting recipes for them here, maybe you'll find some cakes and cookies that you and your wife will both love.
