Low Fat Peanut Butter Cup Blondies

A healthier Peanut Butter Cup Blondie?  Yes, its possible!  Less sugar, less fat, but still the blondie flavor I love!  They are also gluten free (Yes, Reese Peanut Butter Cups are gluten free).  If your not a fan of peanut butter cups, you could substitute for your favorite chocolate bar.  You don’t need much, a few of the fun sized bars chopped up is plenty.  You still get the flavor, but it keeps the calories down.

    Hi Kristine,
    Can I use regular brown sugar instead of raw brown sugar?

    • http://www.busybuthealthy.com Kristine Fretwell

      Yes, regular brown sugar will work.

    Hi Kristine,

    Do you think it would work if I substituted some of the oat flour (say about 1/2 cup) for vanilla protein powder?

    • http://www.busybuthealthy.com Kristine Fretwell

      Yes, subbing up to 1/2 cup oat flour for whey protein should work! You might just want to reduce the cooking time a touch. I’d also maybe add a touch more liquid as the protein absorbs a lot and can dry out the finished product more easily.

      • Carime

        Thanks, Kristine! I subbed 1/4 cup of the oats for protein powder, and added about a 1/2 TBSP of the almond milk. Worked out perfectly!

        • http://www.busybuthealthy.com Kristine Fretwell

          Awesome! Glad it worked out!

    I forgot to buy the stevia. Can I use another 1/2 cup sucanat in replace of the stevia? I tried to find out online but have not had much success. thanks so much!

    • http://www.busybuthealthy.com Kristine Fretwell

      Yes, you can sub with whatever sugar or substitute you prefer.

      • Kim

        I used another 1/2c of the coconut palm sugar and they are delish!! I actually cut the 24pcs into 48 triangles because as good as they are, I find they are really rich. will make them again for sure!!

    Do these need to be refrigerated afterwards?

    • http://www.busybuthealthy.com Kristine Fretwell

      I would put them in the fridge, as they’ll last longer without going bad, but its not totally necessary. They could also be frozen if you want to save some for a later date.
