Hi Bonnie. I've never tried, but I noticed both of those recipes are similar and would probably work. If it was me, I'd just melt some butter and add the maple extract and sweetener to taste, but I don't know if you're trying to make a larger batch or not...

(I chimed in, but I'm hardly the person to ask. I was never a fan of maple syrup. I'm a terrible Canadian, I know... )
