I have substituted all almond flour for the brown rice flour and it still turns out great! For the apple sauce, I use the little organic individual cups it’s the perfect size for this recipe. I also like to cook mine a little longer until the tops are a bit golden brown. It gives it kind of a crunchy top with a super moist inside! TIP!! Don’t let your kids have any of these! They are soooo yummy and you wont have any left for later in the week!! HEHEHEHE!!!
