Tips & Variations
- For richer flavor, be sure to brown the butter slowly and carefully to avoid burning.
- You can substitute rolled oats with quick oats for a softer texture.
- Try adding a pinch of cinnamon or nutmeg to the dry ingredients for a warm spice note.
- If sourdough discard is not available, using an equal amount of active sourdough starter works well.
- For a fun twist, replace vanilla buttercream with cream cheese frosting or chocolate ganache.
Storage
Store the oatmeal cream pies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze for up to 2 months. When ready to enjoy, allow refrigerated or frozen pies to come to room temperature. If desired, warm briefly in the microwave for a softer texture.

FAQs
Can I use regular butter instead of brown butter?
Yes, you can use regular unsalted butter, but browning it adds a nutty, rich flavor that enhances the cookies significantly.
What can I do if I don’t have sourdough discard?
If you don’t have sourdough discard, active sourdough starter can be used in the same quantity, or you can omit it and add a little extra baking soda for leavening, though the flavor may differ slightly.

Ingredients
Cookies
- 1 cup oatmeal
- 1/2 cup all-purpose flour
- 1/2 cup brown sugar (packed)
- 1/4 cup granulated sugar
- 1/2 cup unsalted butter (brown butter)
- 1/2 cup sourdough discard (can use active sourdough starter)
- 1 large egg
- 1 teaspoon vanilla extract
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
Frosting
- 1 cup vanilla buttercream frosting
Instructions
- Preparation: Preheat the oven to 350°F (175°C) to ensure it’s ready when your dough is mixed.
- Cream the Butter and Sugars: In a bowl, combine the browned unsalted butter, brown sugar, and granulated sugar. Cream them together until the mixture is smooth and fluffy, which helps create a tender cookie texture.
- Add Wet Ingredients: Mix in the large egg and vanilla extract to the creamed butter and sugars, stirring until fully incorporated for a cohesive dough.
- Combine Dry Ingredients: In a separate bowl, mix the oatmeal, all-purpose flour, baking soda, and salt. This ensures even distribution of leavening and seasonings.
- Mix Dry and Wet Ingredients: Gradually add the dry mixture to the wet ingredients. Stir gently until just combined to avoid overmixing, which can toughen the cookies.
- Shape the Cookies: Drop spoonfuls of dough onto a lined baking sheet, spacing them to prevent sticking during baking.
- Bake: Bake the dough in the preheated oven for 10-12 minutes or until the cookies are golden brown around the edges, indicating they are cooked through but still soft inside.
- Cool: Remove the cookies from the oven and let them cool completely on a wire rack, which is important to prevent the frosting from melting during assembly.
- Assemble the Cream Pies: Spread a generous amount of vanilla buttercream frosting on the flat side of one cookie, then sandwich it with another cookie, gently pressing together to form a pie.
- Serve: Enjoy your homemade oatmeal cream pies immediately or store them in an airtight container for later enjoyment.
Notes
- Brown butter adds a nutty depth of flavor—take care not to burn it during browning.
- If sourdough discard is not available, active sourdough starter can be used as a substitute without affecting the outcome.
- Ensure cookies are fully cooled before frosting to prevent melting and sliding of the buttercream.
- These cookies keep well in an airtight container for up to 3 days at room temperature or can be refrigerated for up to a week.
- For a gluten-free version, substitute the all-purpose flour with a gluten-free flour blend and ensure oats are certified gluten-free.
