Notes
Use your favorite apples or a varietyWorks great with ground flaxseeds or ground chia seeds or a combinationIf you don't have whole wheat pastry flour, option to do 1/2 whole wheat flour + 1/2 all purpose flour. Whole wheat pastry flour is softer and not as "harsh" tasting as regular whole wheat flour. Also can experiment with using other flours, such as almond flour or coconut flour.
