Prep the base: Add the milk and yogurt to your blender first to help the blades move smoothly.
Add flavor boosters: Add molasses, maple syrup or honey, vanilla, and nut butter if using.
Spice it up: Sprinkle in cinnamon, ginger, nutmeg, and cloves. Add a small pinch of salt if you like.
Finish with fruit and ice: Add the frozen banana and ice cubes.
Blend: Start low, then increase to high until completely smooth and creamy, about 30–60 seconds.
Taste and adjust: Add more sweetener, milk, or spice as needed.
Blend again briefly.
Serve: Pour into a glass and top with a dusting of cinnamon or a dollop of whipped cream for a dessert-style feel.
