Start the filling 15 minutes before the one hour time is up. Using a hand mixer in a small bowl, beat the butter, brown sugar, and cinnamon on high speed for 2 minutes. Set aside.
1/2 cup Unsalted butter, 3/4 cup Brown sugar, 1 TBSP Ground cinnamon
Place cookie butter in a bowl and microwave for 30 seconds so it is melted. Use a food processor to blend the cookies into a fine crumb.
1/2 cup Biscoff cookie butter, 6 Biscoff cookies
On a lightly floured surface, roll the dough into a large rectangle 1/4 inch thick. Use an offset icing spatula to spread cinnamon filling smoothly over all the dough.
Pour the melted cookie butter on top. Spread it until smooth. Sprinkle the cookie crumbs evenly.
Use your hands to roll the dough into a log. Start on the shorter side. Use a serrated knife to cut off the uneven ends. Use light sawing motions to cut the rolls into 12. I cut the log into fourths and each section into thirds.
Spray a 9X13 inch pan with baking nonstick spray. Place the rolls evenly in the pan. Cover with a kitchen towel and rise for 20 minutes.
Preheat the oven to 375℉. Once the rolls are done rising, pour the heavy cream around the gaps of the rolls.
1/3 cup Heavy cream
Bake for 24-27 minutes. Bake until the edges are lightly golden and the inside is 160℉.
