Oatmeal Whoopie Pies
Ingredients
For the oatmeal cookies
- 1 cup (90 g) old-fashioned rolled oats
- 1 cup (125 g) all-purpose flour
- ½ teaspoon baking soda
- ½ teaspoon ground cinnamon
- ¼ teaspoon salt
- ½ cup (113 g) unsalted butter, softened
- ½ cup (100 g) packed brown sugar
- ¼ cup (50 g) granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 2 tablespoons milk, as needed
For the vanilla cream filling
- ½ cup (113 g) unsalted butter, softened
- 1½ cups (180 g) powdered sugar
- 1 teaspoon vanilla extract
- 1–2 tablespoons milk or cream
- ½ cup (approximately 60 g) marshmallow creme, optional for a fluffier filling
Instructions
- Preheat your oven to 350°F (175°C). Line two baking trays with parchment paper to prevent sticking and make cleanup easier.Measure all the ingredients before beginning. Allow the butter and egg to come to room temperature so they combine smoothly and evenly.
- In a medium bowl, whisk together the all-purpose flour, rolled oats, baking soda, ground cinnamon, and salt.Mix until the ingredients are evenly distributed. Set the bowl aside while you prepare the cookie dough.
- In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar until the mixture becomes light and creamy.Add the egg and vanilla extract. Beat again until everything is well combined, scraping down the sides of the bowl when necessary.
- Gradually add the dry ingredient mixture to the butter mixture. Stir until a soft dough forms.Add the milk a little at a time if the dough seems too dry. The finished dough should be soft enough to scoop but firm enough to hold its shape.Avoid overmixing, as excessive mixing can make the cookies tougher than desired.
- Scoop approximately 1 tablespoon of dough for each cookie and place it on the prepared baking trays. Leave about 2 inches between each portion to allow for spreading.Gently flatten the tops if needed to encourage even baking. Try to make the cookies similar in size so the finished sandwiches fit together neatly.
- Bake for 10–13 minutes, checking toward the end of the baking time. The edges should be lightly golden, while the centers should remain soft.Avoid overbaking, because the cookies will continue to firm up as they cool. Remove the trays from the oven and let the cookies rest for 5 minutes before transferring them to a wire rack.Allow the cookies to cool completely before adding the filling.
- Beat the softened butter in a mixing bowl until smooth and creamy.Gradually add the powdered sugar, mixing at a low speed at first to prevent it from scattering. Add the vanilla extract and 1 tablespoon of milk or cream.Beat until the filling becomes light and fluffy. Add the optional marshmallow creme and mix until smooth. If the filling is too thick, add a little more milk; if it is too soft, add extra powdered sugar.
- Pair the cooled cookies according to size. Spread or pipe a generous amount of filling onto the flat side of one cookie.Place a second cookie on top, flat side down, and press gently until the filling reaches near the edges without squeezing out excessively.Repeat with the remaining cookies and filling.
- Allow the assembled Oatmeal Whoopie Pies to rest for 10–15 minutes so the filling settles.Serve immediately or refrigerate briefly for a firmer filling. For the best cookie texture, allow refrigerated whoopie pies to sit at room temperature for a few minutes before serving.
Notes
- Choose old-fashioned oats: Rolled oats provide the best chewy texture for this recipe.
- Use softened butter: Properly softened butter helps create a smooth dough and creamy filling.
- Cool completely: Warm cookies can melt the filling and make the sandwiches slide apart.
- Keep cookies uniform: Similar-sized cookies make attractive, evenly filled whoopie pies.
- Adjust the filling: Add milk gradually to achieve the desired consistency.
- Avoid overbaking: Slightly soft centers help keep the cookies tender after cooling.
- Use parchment paper: It helps prevent sticking and promotes easy removal.
- Check your filling ingredients: Marshmallow creme and other filling products may have different ingredients depending on the brand.
Tips for Oatmeal Whoopie Pies:
- Measure flour accurately: Spoon flour into the measuring cup and level it rather than packing it tightly.
- Chill sticky dough: If the dough is difficult to scoop, refrigerate it for 15–20 minutes.
- Add extra flavor: A small pinch of nutmeg can complement the cinnamon and oats.
- Use a cookie scoop: This creates consistently sized cookies and saves preparation time.
- Do not frost warm cookies: Always wait until they reach room temperature.
- Pipe the filling neatly: A piping bag gives the cream center a professional appearance.
- Experiment with variations: Add raisins, mini chocolate chips, or finely chopped nuts to the cookie dough.
- Store properly: Keep the finished sandwiches in an airtight container and refrigerate if the filling requires it.
FAQs for Oatmeal Whoopie Pies:
1. What are Oatmeal Whoopie Pies?
Oatmeal Whoopie Pies are sandwich-style desserts made with two soft oatmeal cookies and a sweet, creamy filling. They combine the chewy texture of oatmeal cookies with the richness of a filled dessert.
2. Can I use quick oats instead of rolled oats?
Yes. Quick oats can be used, but the cookies may have a softer texture and less noticeable oat pieces. Old-fashioned rolled oats are recommended for a chewier result.
3. Why did my oatmeal cookies spread too much?
Cookies may spread excessively if the butter is too warm, the dough is too soft, or the flour is undermeasured. Chill the dough briefly and check your measurements before baking the next batch.
4. How do I keep the filling from melting?
Make sure the cookies are completely cool before assembling them. Use a filling with a firm consistency, and refrigerate the finished whoopie pies if the filling is temperature-sensitive.
5. Can I make Oatmeal Whoopie ahead of time?
Yes. Bake the cookies a day ahead and store them in an airtight container. Prepare the filling and assemble the sandwiches when convenient, or make the finished whoopie pies ahead and refrigerate them if needed.
6. Can I freeze Oatmeal Whoopie Pies?
Yes. Place the assembled whoopie pies in a freezer-safe airtight container, separating layers with parchment paper. Freeze for up to 2 months for best quality. Thaw in the refrigerator and follow the storage requirements of your filling.
7. Can I make these whoopie pies without cinnamon?
Absolutely. Cinnamon is optional, so you can omit it for a simpler oatmeal flavor or replace it with a small amount of nutmeg.
8. How should I store Oatmeal Whoopie Pies?
Store them in an airtight container. Because buttercream and marshmallow-style fillings vary, refrigeration is a sensible option for homemade filled cookies, particularly in warm weather. Follow the food-safety requirements for the filling used, and avoid leaving perishable fillings at room temperature for extended periods.
9. Can I make the recipe without marshmallow creme?
Yes. The buttercream filling made with butter, powdered sugar, vanilla, and milk works well without marshmallow creme.
