Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C).
Line a baking sheet with parchment paper to prevent the cookies from sticking.
Step 2: Cream the Butter and Sugars
In a large mixing bowl, combine:
- softened butter
- brown sugar
- granulated sugar
Beat the mixture until it becomes light and fluffy. This step helps create soft cookies.
Step 3: Add the Wet Ingredients
Mix in:
- sourdough discard
- egg

Stir until everything is well combined.
The sourdough adds a mild tang that makes these sourdough oatmeal cream pies unique and flavorful.
Step 4: Mix the Dry Ingredients
In another bowl, combine:
- flour
- baking soda
- salt
- cinnamon
Slowly add the dry mixture into the wet ingredients.
Mix gently until just combined.
Step 5: Add the Oats
Stir in the rolled oats until evenly mixed into the dough.
The oats give the cookies their classic chewy texture.
Step 6: Shape the Cookies
Scoop about 1 tablespoon of dough and place it onto the prepared baking sheet.
Leave about 2 inches of space between each cookie.
Flatten them slightly with the back of a spoon.
Step 7: Bake the Cookies
Bake the cookies for 10–12 minutes, or until the edges look lightly golden.
The centers should still be soft.
Let the cookies cool completely before adding the filling.
Step 8: Prepare the Cream Filling
In a bowl, beat together:
- softened butter
- powdered sugar
- vanilla extract
Add milk or cream one tablespoon at a time until the filling becomes smooth and spreadable.
Step 9: Assemble the Cream Pies
Spread or pipe the cream filling onto the bottom of one cookie.
Place another cookie on top to create a sandwich.
Repeat with the remaining cookies.
Your delicious homemade sourdough oatmeal cream pies are now ready to enjoy!
