Ingredients
  

For the Cookies
  • 1 cup sourdough starter Preferably active and bubbly
  • 1/2 cup unsalted butter, softened Make sure butter is at room temperature
  • 1 cup brown sugar Packed
  • 1/2 cup granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 teaspoon cinnamon
  • 3 cups old-fashioned oats
For the Cream Filling
  • 1 cup cream cheese, softened At room temperature for easy mixing
  • 1/2 cup powdered sugar
  • 1 teaspoon vanilla extract

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
  2. In a large bowl, combine the sourdough starter and softened butter. Add both sugars and mix well until creamy. Beat in the egg and vanilla extract until combined.
  3. In another bowl, whisk together the flour, baking soda, salt, and cinnamon. Gradually add this mixture to the wet ingredients, stirring until everything comes together.
  4. Gently fold in the oats until evenly distributed throughout the cookie dough.
  5. Drop tablespoon-sized balls of dough onto the prepared baking sheet, leaving space between each one as they will spread.
Baking
  1. Bake in the preheated oven for 12-15 minutes, or until the edges are golden brown. Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
Cream Filling
  1. While the cookies cool, in a medium bowl, beat together the softened cream cheese, powdered sugar, and vanilla extract until smooth and creamy.
Assembly
  1. Once the cookies are cooled, spread a generous amount of cream filling on the flat side of one cookie and top with another to create a sandwich. Repeat until all cookies are filled.

Notes

For substitutions, coconut sugar can replace brown sugar. For a dairy-free option, use a non-dairy cream cheese alternative. Allow cookies to cool completely before assembling to maintain shape.
