I made these a fourth time to take on a weekend gathering. Today, I added 1/2 tsp. Vietnamese Cassia Cinnamon and a bit of almond extract. I sprinkled sugar over the top of the muffins for added sweetness and some sparkle. Amazing!
Mmmm...Vietnamese cinnamon? That sounds like a lovely addition. In fact, I was re-organizing my spice area since things had gotten a bit out of hand there just two days ago when I came across that Vietnamese cinnamon I bought at Penzey's and thought, "After making such a big ruckus about this stuff on FLDG, I've not used it. Must think of something...." I believe you did!
