I have to admit, I had never tried Biscoff cookie butter before working on his week’s recipe – and it’s delicious! It’s sweet with warm spices, and it immediately made me think of an oatmeal cookie. They complement each other perfectly. These Biscoff Oatmeal Sandwich Cookies are made with cookie butter pressed between two spiced brown sugar and Biscoff oatmeal cookies, and they’re SO soft, warm, and deliciously chewy!
How to Make Biscoff Oatmeal Sandwich Cookies
Biscoff Oatmeal Cookies
I love quick, easy one-bowl cookie recipes, and this one is no exception. To make the cookie dough, first cream together the butter, Biscoff cookie spread, and brown sugar in a large mixing bowl. Add the egg and vanilla extract, stirring until all ingredients are combined. Next, mix in the cinnamon, salt, and baking soda. Using just a bit of cinnamon in these cookies helps to enhance the spice flavor of the cookie butter. Once combined, stir in the flour and finally, the oats.
Scoop the dough onto a parchment-lined baking sheet in 1 tbsp measures. This dough does spread while baking, so a smaller dough ball creates the perfect sized cookie to make a cookie sandwich with. Bake the cookie dough at 350°F until the cookies are set, with golden brown edges, about 10 minutes. Transfer them to a cooling rack and allow them to cool fully before filling them.
Sandwich Cookie Fillings
I chose to fill my cookie sandwiches with more Biscoff cookie butter, but the options are endless! You could fill them with a Biscoff frosting, vanilla buttercream, apple butter, cream cheese frosting, or anything else that you think might pair well.
Storage
The Biscoff Oatmeal Cookies themselves can be stored at room temperature in an airtight container for 3-4 days. If you choose to fill them with something that needs to be refrigerated, like a vanilla buttercream or other dairy-based frosting, store them in the fridge in an airtight container for 2-3 days.
There are lots of options for freezing extra cookies or cookie dough, too. To freeze extra cookie dough, portion out the dough into balls and freeze them on a lined cookie sheet for about four hours. Once frozen, transfer the cookie dough into an airtight bag or container and store until ready to bake, for up to two months. You can bake the dough directly from frozen at 350°F for about 12 minutes, or until golden around the edges. Freeze any extra cookies – filled or not – in an airtight container for up to two months. The cookies will taste best at room temperature, so be sure to take them out of the freezer at least an hour before eating!
These Biscoff Oatmeal Sandwich Cookies are exactly what I would want on a cold or rainy day. They’re comforting – warm, spiced, and sweet, with the perfect chewy soft texture and a creamy filling. I ate mine while enjoying a cup of black tea and a good book. I hope you make these and love them too. Let me know your thoughts in the comments below!
