Using a hand mixer or stand mixer, beat together 4 oz cream cheese, ½ teaspoon vanilla extract, and ¼ cup butter.
Add 1 - 1 ½ cups powdered sugar (½ cup at a time) until you reach the desired consistency and sweetness.
Add the 1 tablespoon maple syrup and 1 teaspoon ground cinnamon to the frosting and mix.
Taste for sweetness and the potency of the maple flavor. If you want the maple stronger, add more syrup combine with mixer.
Frost cake immediately or place frosting in fridge until ready to frost.
Notes
This makes about2 cups of frosting. This is enough for 12-18 cupcakes, 1 8-inch or 9-inch cake layer or 1 cake in a 9x13 pan. If you want to generously frost a two-layer cake, you may want to double it!
