3-Ingredient Chocolate Chip Blondies

Some of the best desserts are the ones that seem almost too good to be true, and these 3-Ingredient Chocolate Chip Blondies are absolutely proof of that. With just a box of yellow cake mix, a few eggs, and a bag of chocolate chips, you can create the most chewy, buttery, and decadent blondies you’ve ever tasted. They’re completely effortless and come together in minutes with almost no cleanup.

I first made these during a late-night baking craving when I had almost nothing in my pantry. The result was pure magic. These blondies are incredibly easy to whip up, require no mixer, and always disappear within minutes. They’re perfect for last-minute gatherings, bake sales, lunchboxes, or just because you need a little chocolatey comfort in your life.

Ingredients

1 box (15.25 oz) yellow cake mix
2 large eggs
½ cup vegetable oil (or melted butter)
1 cup semi-sweet chocolate chips

Directions

Preheat and prepare: Preheat your oven to 350°F (175°C). Line an 8×8-inch or 9×9-inch baking pan with parchment paper or lightly grease it with nonstick spray.
Mix the batter: In a large bowl, combine the yellow cake mix, eggs, and oil. Stir with a spatula or wooden spoon until a thick, cohesive dough forms. The mixture will be thick and slightly sticky.
Fold in the chips: Gently fold in the chocolate chips until they’re evenly distributed throughout the dough.
Transfer to pan: Press the dough evenly into the prepared baking pan, using your hands or the back of a spatula to smooth it into an even layer.
Bake: Bake for 20-25 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out clean or with just a few moist crumbs. Be careful not to overbake—you want them chewy, not cakey.
Cool and slice: Let the blondies cool completely in the pan on a wire rack before slicing into squares.

Variations

White Chocolate Macadamia: Use a white cake mix, fold in white chocolate chips and chopped macadamia nuts.
Peanut Butter Chip: Swap the semi-sweet chips for peanut butter chips for a delicious twist.
M&M Blondies: Fold in 1 cup of M&M candies for a colorful, fun version.
Butterscotch Blondies: Use a butter yellow cake mix and fold in butterscotch chips.
Nutty Blondies: Fold in ½ cup of chopped pecans or walnuts along with the chocolate chips for added crunch.
Swirled Blondies: Dollop ¼ cup of caramel sauce or peanut butter on top of the batter and swirl it through with a knife before baking.

Expert Tips

Don’t overbake: These blondies are best when they’re slightly underdone in the center. They’ll continue to set as they cool, giving you that perfect chewy texture.
Press firmly: The dough is thick, so make sure to press it firmly and evenly into the pan for uniform baking.
Use quality chips: Since chocolate chips are a star ingredient, use good-quality ones for the best flavor.
Line your pan: Parchment paper makes removal and clean-up a breeze, and ensures you get neat, clean slices.
Cool completely: Let the blondies cool fully before slicing to get clean, beautiful squares.

Storage

Store blondies in an airtight container at room temperature for up to 4 days. For longer storage, freeze individual squares in a freezer bag for up to 3 months. Thaw at room temperature before serving.

Frequently Asked Questions

Can I use a different cake mix flavor? Yes. White, butter, or even spice cake mix all work beautifully. Adjust mix-ins accordingly.
Can I use butter instead of oil?Yes. Melted butter adds a richer flavor, but the texture may be slightly softer. Use the same amount.
Why are my blondies cakey instead of chewy? This usually happens if they’re overbaked. Take them out when a toothpick comes out with moist crumbs, not completely clean.
Can I make these gluten-free?Yes. Use a gluten-free yellow cake mix. The results are just as delicious.
Can I double this recipe? Yes. Use a 9×13-inch pan and double all ingredients. Baking time may increase by 5-10 minutes.
