Great recipe! I didn’t have maple syrup so I used honey. I also didn’t have coconut oil so I used butter. I also added about 1t or 2 of pumpkin pie spice. I think the maple syrup would’ve been better per the recipe. But I like that it’s customizable, walnuts would be fantastic. The verdict is still out with my 2 year old, but he’s painstakingly picky with texture sensory issues.
