The smoke detector went off again last Tuesday. Not from something burning, mind you, but from a little incident with the oven and a particularly ambitious batch of sweet potato fries. My husband, bless his patient soul, just sighed and opened all the windows.
He knows by now that my kitchen is less a sterile, perfectly organized space and more a battleground. Flour dusts everything, and spatters of sauce tell stories on the backsplash. It’s where real food happens, not the pretty, manicured stuff you see on those fancy cooking shows. If you enjoy experimenting with low-carb treats, you might also like these rich chocolate almond truffles, which are a personal favorite.
That’s where these Keto Peanut Butter Brownies were born. After many attempts and a few trips to the compost bin, I finally found the balance. There are other takes on this classic out there, like this popular keto brownie interpretation, but I think you will find my version hits just the right fudgy note.
