Note: I used โI Canโt Believe Itโs Not Butterโ and Swerve brown/confectioners sugar to lighten it up. But if youโre going for richnessโstick with the classic ingredients.
๐ฉโ๐ณ Step-by-Step Instructions
1. Melt the Butter
In a saucepan over medium heat, melt the butter until smooth and fragrant. Remove from heat.
2. Create the Buttery Base
Stir in the confectionersโ and brown sugar until the mixture is smooth and combined.
3. Whip the Biscoff & Frosting
In your stand mixer, blend the cream cheese frosting and Biscoff spread until velvety and smooth.
4. Prep the Mixer
Transfer the Biscoff mix to a separate bowl and give the mixer a quick rinse to prep for the next step.
5. Mix the Blondie Batter
Return the butter-sugar mixture to the stand mixer. Add the eggs one at a time with vanilla essence, mixing well after each. Slowly sift in the flour and baking powder, mixing until just combined.
6. Layer the Blondies
Grease a square baking dish and pour in half of the blondie batter, spreading evenly. Add 16 sugar cookies in a single layer on topโtrust the process.
7. Top it Off
Fold white chocolate chips into the remaining blondie batter, then gently spread this over the cookie layer.
8. Bake
Bake at 370ยฐF (188ยฐC) for about 30 minutes, or until the top is golden and a toothpick comes out clean.
๐ง Serving Suggestion
Let cool slightly before slicing into 16 decadent squares. Serve warm with a scoop of vanilla ice creamโor enjoy cold for an ultra-fudgy bite.
