Pumpkin Sandwich Cookies with Brown Butter Buttercream
Ingredients
Equipment
Method
- Preheat oven to 350°F (177°C).
- Line two baking sheets with parchment paper.
- Add pumpkin puree to a fine mesh strainer. Let sit 10–15 minutes to remove excess moisture.
- In a large bowl, whisk together flour, baking powder, baking soda, salt, pumpkin pie spice, cinnamon, and ginger.
- In another bowl, cream softened butter, brown sugar, and granulated sugar for 2 minutes.
- Add the egg and mix for 1 minute.
- Mix in strained pumpkin and milk.
- Gradually add dry ingredients to wet mixture on low speed. Mix until just combined — dough will be thick and sticky.
- Scoop dough (2 tbsp each) onto lined baking sheets, spacing 2 inches apart.
- Bake for 14–15 minutes, until edges are set but centers are soft.
- Cool completely on racks.
- Melt butter in a saucepan over medium heat. Cook 5–7 minutes until butter browns and smells nutty.
- Pour into a heat-safe bowl, including browned bits. Chill 20–30 minutes.
- Whip chilled butter for 1 minute.
- Add powdered sugar and vanilla.
- Add buttermilk 1 tablespoon at a time until smooth.
- Whip 1–3 minutes until fluffy.
- Spread or pipe buttercream onto the bottom of one cookie.
- Top with a second cookie.
- Repeat with remaining cookies.
Notes
- Cookies must be completely cooled before adding buttercream.
- For a thicker filling, reduce buttermilk slightly.
- For extra pumpkin spice flavor, add ½ tsp more cinnamon.
Storage & Make-Ahead Tips:
- Room Temp: Store in airtight container 1–2 days.
- Refrigerate: Up to 5 days (firmer buttercream).
- Freeze: Wrap individually + freeze up to 2 months. Thaw at room temp.
