How to Make Cinnamon Sugar Blondies
Step 1: Prep the Pan
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper or lightly grease it.
Step 2: Mix the Batter
In a medium bowl, stir together the melted butter and brown sugar until well combined. Mix in the egg and vanilla. Add the flour and salt, stirring just until no dry streaks remain.
Step 3: Add the Topping
Spread the batter evenly into your prepared pan. In a small bowl, mix together the sugar and cinnamon, then sprinkle it generously over the top of the batter.
Step 4: Bake
Bake for 22–25 minutes, or until a toothpick inserted into the center comes out mostly clean (a few moist crumbs are okay).
Step 5: Cool and Slice
Let the blondies cool completely in the pan before cutting into bars. This helps them set up and makes slicing easier.
Tips for the Best Blondies
- Don’t overbake! Blondies are meant to be chewy, so take them out when they’re just set in the center.
- Use parchment paper for easy removal and cleaner slices.
- Add a sprinkle of flaky sea salt on top for a sweet-salty contrast.
- Customize it! Fold in chopped pecans, white chocolate chips, or a swirl of Nutella for fun variations.
Storage Instructions
- Room Temperature: Store in an airtight container for up to 4 days.
- Freezer: Wrap tightly and freeze for up to 2 months. Thaw at room temp before serving.
