When making Biscoff Brown Sugar Bars, feel free to substitute the unsalted butter with a dairy-free alternative if you’re looking for a vegan option. If Biscoff spread isn’t available, any crunchy cinnamon spread can work. Just be mindful of allergies, especially with peanuts or gluten, and choose your ingredients accordingly for a safe and tasty treat.

Biscoff Brown Sugar Bars Recipe
Ingredients
- 1/2 cup unsalted butter, room temperature
- 1/4 cup light brown sugar, packed
- 1 cup all-purpose flour
- 1 pinch salt
- 3 large eggs
- 1/4 cup packed light brown sugar
- 1/2 cup cinnamon spread
- 1/2 cup all-purpose flour
Instructions
- Preheat your oven to 350 degrees F and line the bottom of an 8 inch square baking pan with parchment paper. Don’t forget to butter the parchment and the sides of the pan for easy removal later.
- To create the crust, combine 1/2 cup unsalted butter, 1/4 cup packed light brown sugar, 1 cup all-purpose flour, and a pinch of salt in a medium bowl. Use a hand mixer on medium low speed to cream the ingredients together until well combined, though the mixture will remain crumbly.
- Press the crust mixture evenly into the bottom of your prepared pan, using your fingers to ensure it’s packed well. Bake for 15 minutes, rotating the pan halfway through, until the crust is lightly golden brown. Let it cool for a bit while you whip up the filling.
- In another medium bowl, whisk together 3 large eggs, 1/4 cup packed light brown sugar, 1/2 cup Biscoff cinnamon spread, and 1/2 cup all-purpose flour until the mixture is smooth and uniform.
- Pour the delicious filling over the cooled crust, spreading it evenly. Bake for an additional 30 minutes, but resist the urge to check it with a toothpick. You want it just set in the center.
- Let the bars cool completely before slicing. It’s advisable to wait overnight for the best texture. Once cooled, serve and enjoy. The bars can be stored at room temperature for up to 2 days or frozen for up to 3 months, just remember to wrap them well to prevent freezer burn.
