Low Carb Ultra Peanut Butter Zucchini Muffins

I call these the Low Carb Ultra Peanut Butter Zucchini Muffins because other than the peanut butter, there's powdered peanut butter in there replacing some of the flour. A doubly extra overload of peanut buttery goodness.

I’m currently in week I-don’t-remember-the-number of my “I want peanut butter in everything” phase; It’s back in conjunction with the chocolate one this time. On an unrelated note, I’ve also been struggling to get enough veggies in for the day, so sneaking them in sweet treats is where I’m at.

Basically, this recipe is exactly what I needed! 

Made with coconut flour, these Ultra Peanut Butter Zucchini Breakfast Muffins are not only gluten-free, but also low-carb and keto! And to top that off, they’re packed with protein and healthy fats from all the peanut butter.

I based this recipe off of Monique from Ambitious Kitchen’s Grain Free Chocolate Chip Peanut Butter Zucchini Bread, but swapped out the sweetener and also added PbFit powdered peanut butter in. About those chocolate chips, I really really considered them, but it would only be for aesthetic purposes. Basically so that my muffins wouldn’t just look plain golden-brown. I ended up dropping the idea entirely though coz I was just going for the PB right now. I’ll save the chocolate for another day.

An overflowing amount of Peanut Butter flavor is not the only thing extra about these low carb zucchini muffins though. They’re also extra super moist. Think of moist and tender muffin, yeah these are even more moist than that! They just melt in your mouth. I didn’t even know this was a possibility.

A breakfast & dessert option that definitely made me happy on the inside and out!
