Chewy Biscoff oatmeal cookies sandwiched together with a decadent Biscoff white chocolate ganache frosting. The combination of Biscoff spread and chewy oatmeal cookies creates a perfect harmony of flavor and texture.
In the bowl of a standing mixer add butter and mix until softened.
Add the Biscoff spread and brown sugar, mix until combined. Turn the mixer up to medium-high and beat until fluffy.
Fold in the eggs and vanilla.
In a separate large mixing bowl, combine the dry ingredients: oats, flour, baking soda, and salt.
Pour the dry ingredients into the wet ingredients mixture. Mix on low until a dough forms.
Cover the dough in plastic wrap and let rest in the fridge for 1-3 hours.
When ready to bake, preheat the oven to 350 degrees. Scoop the dough with a standard size cookie scoop onto light metal cookie sheet lined with parchment paper.
Bake for 10-12 minutes until the cookies are set. Remove and allow the cookies to rest on the pan for 10 minutes before removing.
White Chocolate Frosting
In a standing mixer combine the butter and powdered sugar. Mix until combined.
In a microwave-safe bowl, combine the cream and white chocolate. Heat in 30-second increments in the microwave, stirring thoroughly in between, until the chocolate is fully melted and smooth.
Add the white chocolate ganache to the butter mixture and mix until combined. Then turn the mixer speed on high and whip for 2 full minutes until the frosting is fluffy.
Biscoff Frosting
In a medium-sized mixing bowl with a hand mixer, combine the Biscoff spread, butter and powdered sugar. Mix until smooth.
Assemble
Fold the two frostings together, but do not fully mix. You want swirled frosting.
Take a cooled cookie, spread frosting on the backside and press a second cookie on top. Repeat until all 20 cookie sandwiches are made.
