Mix the ingrecients for the peanut butter "fudge" together in a bowl. Make room in your freezer for a bread loaf pan to sit flat. Place parcment paper around bread loaf pan (use clips to secure if need be!) Pour mixture into bread loaf pan. Place in freezer while you make jam.
In a small sauce pan combine all the jam ingredients together. Simmer and smash blueberries with a fork gently until it's a suace consistancy (about 3 to 5 minutes) let the mixture cool. Stir together well. Once "fudge" is mostly hard and frozen, pour jam over the top. Spread it evenly over the fudge and place back in the freezer for at least 30 minutes.
Once the jam is hard pull out of the freezer let it warm up for about 2 minutes. Pull fudge out with parchemnt paper (use a spatuala to loosen any sides sticking to the load pan). Keep on parchement paper and slice into bite sized squares on a cutting board. Enjoy.
*store leftovers wrapped in parchment paper on a small plate in freezer and pull out whenever you want a snack!
Notes
* option to use stevia or monk fruit but cut the measurements to taste!
