These frosted sourdough sugar cookies are warm, cozy, and topped with a creamy, simple frosting. Learn how to make this frosted sourdough sugar cookie recipe that's beginner-friendly and is a great way to use up sourdough discard.
In a large bowl, whisk the flour, baking soda, and salt together.
Add softened butter and granulated sugar to the stand mixer. Mix on low-medium speed with a paddle attachment until the sugar is absorbed into the butter, or until most of the butter starts sticking to the sides of the bowl.
Next, add the sourdough discard, vanilla extract, and the egg to the butter-sugar mixture and mix.
On the lowest setting, start slowly adding the dry ingredients to the stand mixture and mix until everything is well combined.
Use a cookie scoop to form the cookie dough balls and chill in the fridge for at least one hour.
Pre-heat your oven to 350 degrees and line your cookie sheet with parchment paper.
Bake your cookies at 350 degrees for 12 - 13 minutes or until the edges are lightly golden brown.
After baking let your cookies cool for at least 5-10 minutes before adding the frosting to the cookies.
Lightly dip the top of the cookie into the frosting to cover the entire surface. You can also use the back of a spoon to smooth out any bumps.
Add sprinkles if desired and allow the frosting to set before storing.
