Notes

Commonly asked questions:
Q. Can I use other flours?
A. Absolutely!  Make sure you check their substitution ratios as some will dry out your bars too much and they won't form correctly.  My favorite flour for this recipe to use is oat flour (although I am not typically a GF eater!).  However, all purpose works too!  1:1 GF all purpose flours are another go to for me.  If you use something else, let me know how it goes in the comments!
Q.  Can I use other fruits?
A. Absolutely!  The biggest thing is to make sure wetness levels are similar.  So some will need to be patted dry (i.e. berries) and then some may need to be cooked down first (i.e. apples).
