Creating Chewy One-Bowl Biscoff Blondies is straightforward with these easy steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease a square baking pan (8×8 inch) or line it with parchment paper for easy removal.

2. Mix Wet Ingredients: In a large mixing bowl, combine the melted butter and Biscoff cookie spread. Stir until smooth and well combined.

3. Add Sugar and Egg: Mix in the brown sugar, followed by the egg and vanilla extract. Blend until fully incorporated and the mixture is glossy.

4. Combine Dry Ingredients: In the same bowl, add the all-purpose flour, baking powder, baking soda, and salt. Stir gently until no flour streaks remain. Be careful not to overmix.

5. Fold in Chocolate Chips: Gently fold in the chocolate chips to distribute them evenly throughout the batter.

6. Pour Batter into Pan: Transfer the batter to the prepared baking pan and spread it into an even layer.

7. Bake: Place the pan in your preheated oven and bake for 25-30 minutes or until the edges are golden and a toothpick inserted into the center comes out with a few moist crumbs.

8. Cool Completely: Remove the pan from the oven and let it cool on a wire rack for 10-15 minutes. If you used parchment paper, lift the blondies out for quicker cooling.

9. Slice and Serve: Finally, slice into squares or rectangles, and enjoy your delicious Chewy One-Bowl Biscoff Blondies!
