I have not tried it in this recipe, but I highly recommend NOT using Bob's Red Mill almond flour. It has very poor results in most almond flour recipes. I used Honeyville Blanched Almond Flour and it worked wonderfully. I've heard good things about the Wellbee's brand also.
If you want a few more nutrients in your sweetener you could 50/50 the maple with local raw honey, or if you're a fan of honey flavor, do the full 1/2 c. honey.
