It’s super delicious. Peanut butter is always been my favourite but had never tried recipes out of it. This is the first one and it turned out to be amazingly yummy and plus it’s eggless. I loved it, thank you so much for the recipe.
This was SO yummy and so easy!
Tastes amazing!! Especially with some white chocolate chips (that’s all I had in my pantry but it tastes so good) recipe is simple to follow and smells like a warm hug
i was really dry and tasted like flour and chocolate
Why, why do you tempt me with your delicious treats?! I am a sucker for all things chocolate and peanut butter, so naturally, I had to try this. I’m not lying when I say this could be my new favorite treat. It’s insanely easy to make, I almost always have the ingredients, and it always satisfies my ever present sweet tooth. I would highly recommend this to anyone.
