Snickerdoodle Cupcakes with Brown Sugar Buttercream

Tender spiced cupcakes with cinnamon and nutmeg, topped with whipped brown sugar buttercream piped into tall peaks and finished with a cinnamon sprinkle. The frosting is beaten until pale and fluffy, creating an airy contrast to the moist cake layers.

Tips
Scrape bowl sides frequently when creaming butter and sugar to ensure even incorporation.
Do not overfill cupcake liners; two thirds full prevents overflow during baking.
Whip butter for the full 5-8 minutes to achieve pale, creamy texture before adding other frosting ingredients.
Frost cupcakes the same day they will be served for best texture and taste.
Good to Know
Cupcakes can be stored up to 2 days at room temperature or frozen up to 2 months in airtight containers. Frosted cupcakes are best eaten the day they are frosted; keep at room temperature until serving.
Baked, unfrosted cupcakes can be frozen up to 2 months in airtight containers. Thaw before frosting.
Serve frosted cupcakes at room temperature.
Common Mistakes
Do not underfill or overfill cupcake liners; two thirds full prevents overflow and ensures even baking.
Do not skip the 5-8 minute butter whipping step; insufficiently beaten butter will result in dense frosting.
Do not frost cupcakes more than one day ahead; frosting texture degrades with storage.
