These blondies use the Biscoff spread I just raved about above, as well as white chocolate chips, to create a creamy and buttery taste that is absolutely delicious! Especially right out of the oven, these are to die for, I promise. You can also use Trader Joe's cookie butter as Biscoff, they are almost exactly the same thing.
Biscoff White Chocolate Blondies
- 1 cup all-purpose flour
- ½ tsp. baking powder
- ⅛ tsp. baking soda
- ½ tsp. salt
- 5 Tbsp. unsalted butter, melted
- 1 cup light brown sugar, packed
- 1 large egg
- 1 egg yolk
- 1 tsp. vanilla extract
- ½ cup Biscoff spread (or Trader Joe's Cookie Butter)
- 1¼ cups white chocolate chips
Preheat oven to 350 degrees. Line a 8x8 or 9x9 baking pan with parchment paper or spray with nonstick spray; set aside.
In a medium sized bowl, toss together the flour, baking powder, baking soda, and salt; set aside. In a large bowl, stir the melted butter and brown sugar together until combined. Whisk in the egg and egg yolk, then add the vanilla. Stir in the Biscoff spread. Gently fold the dry ingredients into the wet ingredients. Be careful not to over mix, which will result in crumbly, hard blondies. The batter will be very thick. Fold in the white chocolate chips.
Spoon the batter into the prepared baking dish. Bake for 25–26 minutes. The blondies may appear very soft, but they will set up as they cool.
