💭 Recipe FAQ
This frosting is stabilized by sugar, so many sources say it can be left out for up to 24 hours. For best results, refrigerate finished cakes and remove them 2–3 hours before serving so the frosting and cake come back to room temperature. Leftovers with this frosting can be left at room temperature for up to 24 hours, but refrigeration is recommended if storing longer.
To make the frosting thicker and more stable, add more powdered sugar or up to 1 tablespoon of a neutral thickener such as instant Clearjel. Whisk any powdered thickener with equal parts powdered sugar first to prevent clumping before folding it into the frosting.

Equipment
Ingredients
- 4 ounces Cream cheese
- 1 ½ sticks (6 ounces) Salted butter (at room temperature)
- 48 grams (¼ cup) Butter-flavored shortening
- 455 grams (3 ½ cups) Powdered sugar
- 1 ½ teaspoon Cinnamon
- 1 Tablespoon Pure vanilla extract
Instructions
Make Cinnamon Buttercream
- Using a stand mixer (preferred) or handheld mixer, beat the cream cheese until smooth and broken up.
- Add the room-temperature salted butter and beat until no lumps remain, scraping the bowl as needed.
- Add the shortening and continue to beat and scrape until the mixture is smooth.
- With the mixer on low, slowly sprinkle in the powdered sugar and cinnamon. The mixture will thicken; continue to incorporate the sugar slowly until fully mixed.
- Add the pure vanilla, scrape down the sides of the bowl, then beat the buttercream on high for 2–3 minutes. This aerates the frosting and makes it light and fluffy.
- If not serving within 24 hours, refrigerate the frosting. Remove it a couple of hours before using so it returns to room temperature and regains a spreadable texture.
