These homemade blondie bars are so chewy, dense, and full of rich caramel flavor! They only require 6 ingredients and 5 minutes to whip up the batter. I highly recommend making them for your next get-together—they'll be sure to wow the crowd!
Preheat oven to 350°F/177°C. Spray and line an 8x8-inch metal baking pan with parchment paper.
In a large mixing bowl add 1 ¼ cups brown sugar. Break up any clumps with your hands or whisk. Then, whisk in ½ cup oil, 2 eggs, and 1 tablespoon vanilla until smooth.
Add in 1 ½ cup all-purpose flour and 1 ½ teaspoon fine sea salt. Mix until no dry spots remain.
Pour blondie batter into lined baking pan and use spatula to evenly spread it out. Bake for 35-40 minutes and remove from oven. To test if it is done, stick a toothpick in the middle. If it comes out mostly clean with a few crumbs, it's finished baking.
Allow to fully cool in pan for about one hour. It is well worth the wait because when they're warm, they're more cake-like. But once fully set, they're super chewy!
Remove blondies from pan and cut into 16 squares. Enjoy! :)

Notes
Baking tip:
Weigh your ingredients! One of my favorite kitchen tools is a kitchen scale because it’s more accurate than measuring by volume. If you use cups, spoon the flour in gently, then level it with a knife or spatula.
Ingredient notes:
For a richer molasses flavor, use dark brown sugar. Otherwise, light brown sugar works well, too.
If you don't want to use oil, you can sub in melted unsalted butter. This will create a softer, cakier blondie bar.
Storage instructions:
Room temperature: Store cooled blondies in an airtight container at room temperature for up to 5 days.
Freezing instructions: Store cooled blondies in a freezer-safe container for up to 3 months.
Reheating instructions: Allow frozen blondies to thaw at room temperature for about 15 minutes. Or, reheat in the microwave at 10-second intervals.
