Keto peanut butter brownies topped with sugar free peanut butter fudge



These amazing and mouth-watering KETO PEANUT BUTTER BROWNIES are topped with a rich sugar free peanut butter fudge and a sweet chocolate glaze. Perfect for any kind of occasions/ceremonies.


Are you a buckeye fan? These are also known as Buckeye Brownies. That nut is the inspiration for buckeye candy, which is a ball of peanut butter fudge dipped in chocolate, made to resemble the buckeye nut.

Buckeyes are so beloved in Ohio and that love has extended far and wide, so that now almost anything made with peanut butter and chocolate can be referred to as “buckeye”. I am not above exploiting that love of peanut butter and chocolate. Because I love it too and will eat just about anything made with these two ingredients. It’s hard for me to resist.

  1. Begin with the best, fudgiest, gooiest keto brownies around. I had a pretty great recipe back in the day but ever since I discovered using a little gelatin to improve the chewiness of my keto cookies and brownies, I’ve been using my Ultimate Keto Brownies recipe as the base for any brownie recipe.
  2. Use quality ingredients like Bob’s Red Mill almond flour. Not all almond flour is created equal, my friends. You may have heard me expound on this before and you will hear me expound on it again. Finely ground blanched almond flour is a MUST for all of your keto baked goods.
  3. Use the creamiest peanut butter you can find. A lot of natural peanut butters aren’t as creamy as I would like and have that thick layer of oil on the top.
  4. Both are very creamy and not overly oily, and make the peanut butter fudge layer on these brownies so creamy and delicious.
  5. Use enough powdered Swerve to thicken the peanut butter layer so that it’s spreadable but not too thin. You really want this to be like a fudge layer on top of the brownies.
  6. Make a creamy sugar free chocolate ganache to go on top. I did some where I spread the ganache and some where I just drizzled it. You could spread the whole batch with a thin layer of the chocolate ganache. Or you could do as I did and cut the peanut butter brownies up first, and then drizzle or spread as you see fit.
