Ingredient Notes

Biscoff Cookie Butter: This creamy spread is the star ingredient, providing a distinctive caramelized flavor with subtle warm spices. Use the smooth variety for the best texture.

Unsalted Butter: Slightly cold butter helps create thick cookies, while butter in the filling provides richness and structure. Cut it into small cubes to make mixing easier.

All-Purpose Flour: Provides structure and helps the cookies hold their shape during baking.

Granulated Sugar: Sweetens the cookie dough and contributes to the lightly crisp edges.

Eggs: Help bind the ingredients together and give the cookies a soft, tender texture.

Crushed Biscoff Cookies: Add extra flavor and a subtle crunch to both the dough and buttercream.

Powdered Sugar: Creates a smooth, fluffy filling that is easy to spread or pipe between cookies.

Directions

Step 1: Prepare the Oven and Baking Sheet

Preheat your oven to 350°F (180°C). Line a large baking sheet with parchment paper to prevent sticking and promote even baking.

Make sure the oven is fully preheated before placing the cookies inside.

Step 2: Combine the Dry Ingredients

In a medium mixing bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt.

Mix thoroughly to distribute the leavening agents evenly throughout the flour. Set the bowl aside.

Step 3: Cream the Butter, Cookie Butter, and Sugar

In a large mixing bowl, combine the slightly cold unsalted butter, smooth Biscoff cookie butter, and granulated sugar.

Using a hand mixer or stand mixer, beat the ingredients until the mixture becomes light, creamy, and fluffy.

Scrape down the sides of the bowl as needed to ensure everything is evenly incorporated.

Step 4: Add the Eggs and Vanilla

Add the cold eggs one at a time, beating well after each addition.

Pour in the vanilla extract and mix until incorporated.

Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined.

Gently fold in the finely crushed Biscoff cookies using a spatula.

Avoid overmixing the dough, as this can make the finished cookies tough.

Step 5: Shape and Bake the Cookies

Using an ice cream scoop, portion the dough into golf ball-sized balls.

Arrange them on the prepared baking sheet, leaving enough space between each cookie for spreading.

Bake for 13–14 minutes, or until the edges are lightly golden and the centers appear just set.

Remove the baking sheet from the oven and allow the cookies to cool on the tray for 5 minutes.

Transfer them to a wire rack and let them cool completely before adding the filling.

Step 6: Prepare the Biscoff Buttercream Filling

In a large mixing bowl, beat the slightly cold unsalted butter and smooth Biscoff cookie butter until creamy and well combined.

Gradually add the powdered sugar, mixing on low speed initially to prevent it from scattering.

Increase the mixer speed and beat until the filling becomes smooth, light, and fluffy.

Add the finely crushed Biscoff cookies and mix until evenly distributed.

If the buttercream feels too firm to spread, allow it to soften slightly at room temperature before assembling the cookies.

Step 7: Assemble the Sandwich Cookies

Pair cookies of similar sizes to create evenly shaped sandwiches.

Turn one cookie upside down and spread or pipe a generous layer of Biscoff buttercream onto its flat side.

Place a second cookie on top, flat side facing the filling, and gently press until the buttercream reaches near the edges.

Repeat with the remaining cookies and filling.

For a neater presentation, use a piping bag fitted with a round or star tip.

Step 8: Serve and Enjoy

Serve the Biscoff Sandwich Cookies immediately for a soft, creamy treat, or refrigerate them briefly to help the filling firm up.

For the best texture and flavor, allow chilled cookies to sit at room temperature for a few minutes before serving.

Servings and timing

The number of finished sandwich cookies depends on the size of your dough portions. Smaller scoops will produce more sandwiches, while larger scoops will create thicker bakery-style cookies.

Remember that the cookies must cool completely before filling, so the actual elapsed time may be longer than 29 minutes.

Variations

1. Chocolate-Dipped Biscoff Sandwich Cookies

Dip half of each assembled sandwich cookie into melted dark or milk chocolate. Place the cookies on parchment paper and let the chocolate set before serving.

The chocolate adds richness and balances the sweet, caramelized Biscoff flavor.

2. White Chocolate Biscoff Cookies

Drizzle melted white chocolate over the assembled cookies for a beautiful finish.

You can also sprinkle additional crushed Biscoff cookies over the drizzle before it hardens.

3. Extra-Crunchy Biscoff Sandwich Cookies

Replace the smooth Biscoff cookie butter in the filling with crunchy cookie butter for additional texture.

This variation adds small cookie pieces throughout the buttercream.

4. Cinnamon Biscoff Sandwich Cookies

Add ½ teaspoon ground cinnamon to the dry ingredients for an extra layer of warmth and spice.

This variation is especially delicious during autumn and winter.

5. Mini Biscoff Sandwich Cookies

Use a smaller cookie scoop to make bite-sized cookies.

Reduce the baking time slightly and monitor them closely to prevent overbaking.

Mini sandwiches are perfect for dessert trays, parties, and afternoon tea.

6. Salted Caramel Biscoff Cookies

Add a thin drizzle of salted caramel over the buttercream before placing the second cookie on top.

The slight saltiness helps balance the sweetness of the filling.

7. Cream Cheese Biscoff Filling

Replace part of the butter in the filling with full-fat cream cheese for a slightly tangy flavor.

This variation creates a softer filling, so the assembled cookies should be refrigerated.

Storage/Reheating

Room Temperature Storage

Store the assembled Biscoff Sandwich Cookies in an airtight container at cool room temperature for up to 2 days.

Keep them away from direct sunlight, heat, and humidity to prevent the buttercream from becoming too soft.

Refrigerator Storage

Place the sandwich cookies in a single layer inside an airtight container, or separate stacked layers with parchment paper.

Refrigerate for up to 5 days.

Before serving, let the cookies sit at room temperature for approximately 15–20 minutes to soften the buttercream and improve their texture.

Freezer Storage

Biscoff Sandwich Cookies can be frozen for up to 2 months.

Arrange the assembled cookies on a baking sheet and freeze until firm.

Transfer them to a freezer-safe container, placing parchment paper between layers to prevent sticking.

Thaw the cookies in the refrigerator overnight, then allow them to reach a comfortable serving temperature.

Can You Reheat Biscoff Sandwich Cookies?

Reheating assembled sandwich cookies is not recommended because the buttercream can melt and lose its fluffy consistency.

If you prefer a warm cookie, gently warm an unfilled cookie for a few seconds in the microwave before adding the buttercream.

Never microwave an assembled sandwich cookie for an extended period, as the filling may become runny.

FAQs

1. What are Biscoff Sandwich Cookies?

Biscoff Sandwich Cookies are homemade cookies made with Biscoff cookie butter and crushed Biscoff biscuits. Two baked cookies are joined together with a creamy Biscoff buttercream filling, creating a rich dessert with a sweet, caramelized flavor.

2. Can I use crunchy Biscoff cookie butter instead of smooth?

Yes, crunchy Biscoff cookie butter can be used in both the dough and filling. It will add small cookie pieces and a slightly more textured consistency. Smooth cookie butter is generally preferred for a silky, easy-to-pipe buttercream.

3. Why did my Biscoff cookies spread too much?

Excessive spreading can happen when the butter is too warm, the dough is overmixed, or the baking sheet is hot. Measure the flour carefully, use slightly cold butter as directed, and avoid placing dough on a warm baking sheet. If the dough feels very soft, refrigerate it for 20–30 minutes before baking.

4. Can I make the cookie dough ahead of time?

Yes. Prepare the dough, cover it tightly, and refrigerate it for up to 48 hours. When ready to bake, scoop the dough into portions and bake as directed. Chilled dough may require an additional minute or two in the oven.

5. How do I keep the Biscoff buttercream from becoming too runny?

Use slightly cold butter and avoid adding extra liquid. Beat the butter and cookie butter until creamy before gradually incorporating the powdered sugar. If the filling becomes too soft, refrigerate it for 10–15 minutes, then mix briefly before using.

6. Can I freeze the cookie dough?

Yes. Scoop the dough into individual portions and arrange them on a parchment-lined tray. Freeze until firm, then transfer the dough balls to a freezer-safe bag or container. Store for up to 2 months. Bake from frozen, adding a few extra minutes as needed.

7. How do I make evenly sized sandwich cookies?

Use a cookie scoop to portion the dough consistently. After baking, match cookies with similar diameters before adding the filling. This creates neat, uniform sandwiches that are easier to stack, store, and serve.

8. Can I make these cookies without a stand mixer?

Absolutely. A handheld electric mixer works well for preparing both the dough and buttercream. You can also mix by hand using a sturdy whisk and spatula, although creaming the butter and sugar will require more effort.

9. Why do the cookies need to cool completely before filling?

Warm cookies can melt the Biscoff buttercream, causing it to become runny and leak from the sides. Cooling the cookies completely helps the filling maintain its fluffy consistency and keeps the sandwiches neatly assembled.

10. Can I decorate Biscoff Sandwich Cookies for special occasions?

Yes. You can roll the exposed buttercream edges in crushed Biscoff cookies, drizzle melted chocolate over the tops, or dust them lightly with powdered sugar. For celebrations, place the finished cookies in decorative paper liners or package them in small gift boxes.
