What Ingredients You Will Need

This recipe uses straightforward ingredients that come together to create a classic chocolate chip cookie flavor but in bar form. Most are pantry staples, and I’ve included some notes for easy swaps or tips to get the best texture.

• All-purpose flour (2 cups / 250g) – The base that gives structure; I prefer King Arthur for consistent results.
• Baking soda (1 tsp) – Helps the bars rise just enough without puffing up like cookies.
• Salt (½ tsp) – Balances sweetness and enhances flavor.
• Unsalted butter (½ cup / 113g, melted) – Adds richness and chewiness; I use Land O Lakes when I can.
• Brown sugar (¾ cup / 150g, packed) – Gives moisture and that classic caramel flavor.
• Granulated sugar (¼ cup / 50g) – Balances sweetness and helps create a slight crispiness around the edges.
• Large egg (1, room temperature) – Binds everything together.
• Vanilla extract (1 tsp) – For that warm, inviting aroma.
• Chocolate chips (1 ½ cups / 270g) – Semi-sweet or milk chocolate, whatever you prefer; I usually go with Ghirardelli chips for the melty texture.

Substitution tip: For a gluten-free option, swap the all-purpose flour with a 1:1 gluten-free baking flour blend. If you want to make it dairy-free, use coconut oil instead of butter and dairy-free chocolate chips.

Equipment Needed

• Large mixing bowl: Since this is a one-bowl recipe, choose something spacious enough to mix without spills. A glass or stainless steel bowl works great.
• Measuring cups and spoons: Accuracy helps with consistent results, but a kitchen scale is even better if you have one.
• Wooden spoon or sturdy silicone spatula: For mixing; no mixer needed, but you’ll want a strong tool to combine melted butter and sugars smoothly.
• Baking pan: An 8×8-inch (20x20cm) square pan is perfect. You can line it with parchment paper for easy removal.
• Oven mitts: Safety first – these bars come out hot and tempting!

If you don’t have parchment paper, lightly grease the pan with butter or non-stick spray. I’ve tried both, and parchment makes cleanup a breeze, especially when those chocolate chips melt and stick.

Preparation Method

1. Preheat your oven to 350°F (175°C). Grease or line an 8×8-inch baking pan with parchment paper, leaving a bit of overhang on the sides for easy lifting.
2. Melt the butter: In your large mixing bowl, microwave the unsalted butter for about 30 seconds until fully melted (or melt on the stove). Let it cool slightly so it doesn’t cook the egg later.
3. Add sugars: To the melted butter, add ¾ cup packed brown sugar and ¼ cup granulated sugar. Stir with your wooden spoon or spatula until the mixture is smooth and glossy.
4. Mix in the egg and vanilla: Crack in one large room temperature egg and pour in 1 teaspoon vanilla extract. Mix vigorously until fully combined—this step is key for a smooth batter.
5. Combine dry ingredients: In a separate small bowl or directly over the wet mixture, whisk together 2 cups all-purpose flour, 1 teaspoon baking soda, and ½ teaspoon salt.
6. Incorporate dry into wet: Gradually add the flour mixture into the wet ingredients. Stir gently until just combined—don’t overmix or you’ll get tough bars. The batter will be thick and slightly sticky.
7. Add chocolate chips: Fold in 1 ½ cups of your favorite chocolate chips evenly throughout the batter.
8. Spread into pan: Using a spatula, spread the batter evenly into your prepared baking pan, pressing lightly to smooth the surface.
9. Bake: Place in the oven and bake for 25–30 minutes. Start checking around 23 minutes; the edges should be golden and the center set but still soft.
10. Cool and slice: Let the bars cool completely in the pan on a wire rack. Use the parchment overhang to lift them out, then slice into squares or rectangles.

Pro tip: If your bars seem underbaked in the center but the edges are golden, tent the pan loosely with foil and bake for 3–5 more minutes. I’ve learned this the hard way when rushing the timer!

Cooking Tips & Techniques

One-bowl baking is about simplicity, but a few tricks help make these cookie bars shine. First, melting the butter instead of creaming it saves time and yields a chewier texture—perfect for bars. Don’t skip letting the melted butter cool; otherwise, you risk scrambling the egg.

Mix your dry ingredients well before adding them to the wet mix. This avoids pockets of baking soda or salt. When combining wet and dry, fold gently—overmixing develops gluten, making bars tough instead of tender. I’ve learned this after a couple of chewy mistakes!

Keep an eye on baking time. Every oven bakes a bit differently; too long and the bars dry out, too short and they’re gooey in a less-than-pleasant way. Look for a golden edge and a firm center that springs back slightly.

For multitasking, I often prepare the dry ingredients while the butter melts. This saves precious minutes and keeps the process smooth—because who wants to wait when a sweet treat is calling?

Variations & Adaptations

• Nutty Upgrade: Stir in ½ cup chopped walnuts or pecans for crunch and earthy flavor.
• Peanut Butter Swirl: Dollop ⅓ cup peanut butter on top of the batter and swirl with a knife before baking for a rich twist.
• Seasonal Fruit Chips: Replace chocolate chips with dried cherries or cranberries in fall and winter for a tart pop.

If you want a healthier spin, swap half the flour for whole wheat pastry flour—just expect a denser bar. For a vegan version, use flaxseed egg replacement and coconut oil instead of butter, plus dairy-free chocolate chips. I tried this once for a friend’s visit, and it was surprisingly satisfying.

Serving & Storage Suggestions

Serve these bars slightly warm for the best melty chocolate experience. They’re fantastic with a glass of cold milk or a cup of coffee. For parties, cut into bite-sized squares and arrange on a platter for an inviting presentation.

Store leftovers in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze tightly wrapped for up to 3 months. To reheat, microwave a bar for 10–15 seconds or warm briefly in the oven to bring back that just-baked softness.

Flavors tend to deepen after a day, so if you can wait, letting the bars rest overnight can make them taste even better. I know it’s hard, but trust me on this one!
