Sourdough Snickerdoodle Cupcakes with Cinnamon Cream Cheese Frosting

These sourdough snickerdoodle cupcakes taste just like a classic snickerdoodle cookie, but in light, fluffy cupcake form. Each cupcake is loaded with warm cinnamon flavor and topped with a rich cinnamon cream cheese frosting that truly melts in your mouth. The combination of whole milk, sour cream, and sourdough discard creates an incredibly soft, moist crumb with bakery-style texture. These cinnamon cupcakes are the perfect dessert for autumn and winter baking, cozy holidays, birthday parties, and any time you’re craving a sweet cinnamon treat.

Ingredients

Snickerdoodle Sourdough Cupcakes

  • 2 cups all-purpose flour
  • 2 teaspoons baking powder
  • 2 teaspoons ground cinnamon
  • 1/4 teaspoon salt
  • 1 1/2 cups granulated sugar
  • 8 tablespoons salted butter melted
  • 2 large eggs room temperature
  • 3/4 cup whole milk room temperature
  • 1/2 cup sour cream room temperature
  • 1/2 cup sourdough discard
  • 2 teaspoons vanilla extract

Cinnamon Cream Cheese Frosting

  • 8 ounces cream cheese softened
  • 16 tablespoons unsalted butter softened
  • 2 teaspoons vanilla extract
  • 1/4 teaspoon salt
  • 1 tablespoon ground cinnamon
  • 4 cups powdered sugar sifted

Instructions

Make the Cupcakes

  • Preheat your oven to 350°F (177°C) and line two cupcake pans with 21 cupcake liners. *See note below if you'd like to make mini sourdough snickerdoodle cookies to top the cupcakes with.
  • In a medium bowl, whisk together the flour, baking powder, cinnamon, and salt.
  • In a large mixing bowl, whisk together the melted butter and sugar until well combined. Add the eggs and vanilla and mix until smooth.
  • Add the sour cream and sourdough discard and whisk until fully incorporated.
  • Gradually mix in half of the milk, followed by half of the dry ingredients. Stir to combine, then add the remaining milk and remaining dry ingredients. Mix until just incorporated.
  • Divide the batter between the cupcake liners, filling each about two-thirds full.
  • Bake for 20 to 22 minutes, or until a toothpick inserted into the center comes out clean.
  • Cool cupcakes in the pan for 5 minutes, then transfer to a wire rack to cool completely before frosting.

Make the Cinnamon Cream Cheese Frosting

  • In a stand mixer fitted with the paddle attachment, or using a hand mixer, beat the softened butter and cream cheese on medium speed until smooth and fluffy, about 2 to 3 minutes.
  • Add the vanilla, salt, and cinnamon and mix until combined.
  • Gradually add the powdered sugar, mixing on low until incorporated, then increase to medium speed and whip for 1 to 2 minutes until light and fluffy.
  • Frost cooled cupcakes using a piping bag or offset spatula.

Notes

*Note* If you'd like to add the mini snickerdoodle cookies to the top of these cupcakes, I recommend making them ahead of time. I use this sourdough snickerdoodle cookie recipe and cut it in half to make mini cookies. You could even cut it in 1/4, but it's always fun to have extra cookies!

Storage

  • Room temperature: 1 day, covered
  • Refrigerator: 3 to 4 days in an airtight container
  • Freezer: Freeze unfrosted cupcakes up to 2 months, thaw before frosting
