Portion the Cookie Dough
Scoop the dough into golf ball-sized portions. An ice cream scoop keeps every cookie the same size so they air fry evenly and pair up perfectly as sandwiches.
Air Fry the Cookies
Line your air fryer basket, then place the dough balls in batches, leaving space between each one. Parchment paper makes cleanup a breeze and keeps the cookies from sticking.
Air fry at 350°F (180°C) for 6–7 minutes. Let the cookies cool in the basket before transferring them to a wire rack to cool completely.
Make the Filling
In a large bowl, beat the butter and Biscoff cookie butter together until creamy. Add the powdered sugar and crushed Biscoff cookies and mix until the filling is smooth and fluffy.
Assemble the Sandwich Cookies
Spread or pipe the filling onto the flat side of one cookie for cleaner, more even sandwiches. I love using a piping bag for more control and a bakery-perfect finish.
Top with a second cookie and press gently to sandwich them together. Repeat with the remaining cookies.
Serve and Enjoy
Arrange the finished cookies on a plate or tiered stand and serve at room temperature for the softest, most indulgent bite.
These travel well to cookie swaps, bake sales, and holiday gatherings. Stack them in a single layer in a cookie tin, separating layers with parchment to keep the filling intact during transport.
Ingredients
For the Cookies:
- 2 ½ cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- ½ teaspoon salt
- ¾ cup unsalted butter slightly cold
- ½ cup smooth Biscoff cookie butter
- 1 cup sugar
- 2 cold eggs
- 1 teaspoon vanilla extract
- ¼ cup Biscoff cookies finely crushed
For the Filling:
- ¾ cup unsalted butter slightly cold
- ¾ cup smooth Biscoff cookie butter
- 2 cups powdered sugar
- ¼ cup Biscoff cookies finely crushed

- Spread or pipe filling onto the flat side of one cookie. Top with another cookie to make a sandwich. Repeat with remaining cookies.
Notes
- Use slightly cold butter: Slightly cold butter (not fully softened) helps the cookies hold their shape in the air fryer, preventing them from spreading too flat.
- Crush the cookies finely: Make sure the Biscoff cookies are crushed into fine crumbs, not chunky pieces, so they blend smoothly into both the dough and the filling without affecting the texture.
- Don’t overmix the dough: Mix the dry ingredients in until just combined. Overmixing can make the cookies tough instead of soft and tender.
- Cool completely before filling: The cookies need to be fully cooled before you add the filling, otherwise the butter-based filling will melt and slide right off.
- Match your cookies by size: Pair up similar-sized cookies before you start filling so every sandwich looks even and holds together well.
- Flash-freeze before storing: If you’re making a big batch, freeze the assembled cookies on a baking sheet for about an hour before transferring them to a container so the filling sets, and they don’t stick together.

How to Store Leftovers
Store the cookies in an airtight container at room temperature for up to 3 days, or in the fridge for up to a week. The filling holds up well chilled, and the cookies actually taste great cold straight from the fridge.
To freeze, place the assembled sandwich cookies in a single layer on a baking sheet and freeze until solid, then transfer to a freezer-safe container with parchment between the layers. They’ll keep in the freezer for up to 2 months. Thaw at room temperature for about 30 minutes before serving.
What to Serve With Air Fryer Biscoff Sandwich Cookies
A cold glass of milk is the classic pairing here, and it’s classic for a reason. The creamy, spiced filling and soft cookies balance out beautifully with something cool and simple alongside. A hot cup of coffee or a chai latte also works really well, since the warm spice notes in the Biscoff naturally play off those flavors.
For a more indulgent spread, set these out next to a scoop of vanilla ice cream or a mug of hot chocolate. They also pair nicely on a dessert platter with other cookie butter treats if you’re hosting a gathering or putting together a holiday cookie box.
