What You’ll Need
For the Blondie Bars:
- Butter: 1/2 cup (1 stick) unsalted butter, melted
- Brown Sugar: 1 cup packed light brown sugar (the secret to that rich, caramel-like flavor)
- Egg: 1 large egg, room temperature
- Vanilla Extract: 1 teaspoon pure vanilla extract
- All-Purpose Flour: 1 cup all-purpose flour
- Baking Powder: 1/2 teaspoon baking powder
- Salt: 1/4 teaspoon fine sea salt
- Chocolate Chips: 3/4 cup semi-sweet chocolate chips (plus extra for topping)
Substitution Notes:
- Butter: Can substitute with coconut oil (melted and cooled) for dairy-free option
- Brown Sugar: Light or dark brown sugar both work—dark creates a deeper molasses flavor
- Chocolate Chips: Try white chocolate chips, butterscotch chips, or chopped walnuts for variety
- Flour: For gluten-free, use a 1:1 gluten-free flour blend
Step-by-Step Directions
- Preheat and Prep: Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving some overhang for easy removal. Lightly grease the parchment with cooking spray.
- Melt the Butter: In a large mixing bowl, melt the butter completely. Let it cool for 2-3 minutes—you want it warm but not hot enough to cook the egg.
- Mix Wet Ingredients: Whisk in the brown sugar until well combined. The mixture should look smooth and glossy. Add the egg and vanilla extract, whisking until everything is fully incorporated.
Pro Tip: Make sure your egg is at room temperature! Cold eggs can cause the melted butter to seize up and create a grainy texture.
- Add Dry Ingredients: Sprinkle the flour, baking powder, and salt over the wet ingredients. Using a wooden spoon or rubber spatula, gently fold everything together until just combined. Don’t overmix—you want to see just a few flour streaks.
- Fold in Chocolate Chips: Add 3/4 cup chocolate chips and fold them in gently. Reserve a handful of extra chips for sprinkling on top.
- Transfer to Pan: Spread the batter evenly in your prepared baking pan. Use an offset spatula or the back of a spoon to smooth the top. Sprinkle the remaining chocolate chips over the surface.
- Bake to Perfection: Bake for 22-25 minutes until the edges are set and lightly golden. The center should still look slightly underdone—it will continue cooking as it cools.
Don’t Overbake: The secret to fudgy blondies is knowing when to stop! A toothpick inserted in the center should come out with a few moist crumbs, not completely clean.
- Cool Completely: Let the blondies cool completely in the pan before cutting—this takes about 1 hour. Use the parchment paper overhang to lift them out, then cut into 16 squares.
How to Serve
These Easy One-Bowl Fudgy Blondie Bars are delicious on their own, but here are some ways to take them over the top:
Classic Serving: Cut into squares and serve at room temperature with a cold glass of milk or hot coffee.
Elevated Dessert: Warm a square for 10-15 seconds in the microwave and top with vanilla ice cream and a drizzle of caramel sauce.
Party Presentation: Dust with powdered sugar or drizzle with melted chocolate for an elegant finish.
Pack for Gifts: Wrap individual bars in cellophane for perfect lunch box treats or hostess gifts.
Expert Tips for Success
Storage: Store blondie bars in an airtight container at room temperature for up to 5 days. For longer storage, wrap individually and freeze for up to 3 months.
Make Ahead: These bars actually taste better the next day! The flavors meld together and the texture becomes even more fudgy.
Cutting Clean Squares: Use a sharp knife wiped clean between cuts, or run it under warm water and dry before slicing.
Texture Variations: For chewier bars, underbake by 2-3 minutes. For more cake-like texture, bake an additional 3-4 minutes.
Flavor Boost: Brown your butter before adding it to the mixture for an extra nutty, caramel flavor. Just let it cool completely first.
Mix-in Ideas: Try adding 1/2 cup of your favorite mix-ins: chopped pecans, dried cranberries, mini marshmallows, or even a swirl of peanut butter.
Common Questions
Can I double this recipe?
Absolutely! Double all ingredients and use a 9×13-inch pan. Increase baking time to 28-32 minutes, checking for doneness with a toothpick.
Why are my blondies dry?
Overbaking is the most common culprit. Remember, they should look slightly underdone in the center when you remove them from the oven. Also, make sure you’re measuring flour correctly—spoon it into the cup and level off.
Can I make these without eggs?
Yes! Replace the egg with 1/4 cup unsweetened applesauce or 1 tablespoon ground flaxseed mixed with 3 tablespoons water (let sit for 5 minutes to thicken).
How do I know when they’re done?
The edges should be set and lightly golden, while the center should still look slightly shiny and underdone. A toothpick inserted in the center should come out with moist crumbs, not wet batter.
Can I use dark brown sugar instead of light?
Definitely! Dark brown sugar will give you a deeper, more molasses-forward flavor. The texture will be exactly the same.
