You know the drill: the school fundraiser email lands in your inbox, and suddenly you're staring down a bake sale sign-up sheet with your name already on it. Panic sets in as you imagine spending your entire Saturday rolling dough and washing mixing bowls. But what if I told you there's a way to show up with something that sells out in minutes, without turning your kitchen into a flour bomb?

Enter the Best Things For Bake Sale: chewy, chocolate-packed cookie bars that come together in one bowl and bake in a single pan. No rolling, no chilling, no fuss. Just slice, wrap, and watch them disappear. I've tested this recipe at three different school events, and it's never failed to sell out before the cupcakes even get their frosting on.
The secret? A slightly underbaked center that stays fudgy, a crackly top, and just enough sea salt to make people do that little 'oh wow' eyebrow raise. Plus, they're sturdy enough to stack in a box without crumbling into a mess. That's the kind of bake sale hero you want to be.
Why You'll Love This Recipe
About the Ingredients
1 cup (2 sticks / 227g) unsalted butter, melted
Melted butter gives the bars a chewy texture. Use salted butter and reduce the added salt to 1/4 teaspoon if that's what you have.
1 cup (200g) packed light brown sugar
Brown sugar adds moisture and a deep caramel flavor. You can substitute dark brown sugar for a stronger molasses note.
1/2 cup (100g) granulated sugar
Granulated sugar helps create that crackly top. If you prefer a less sweet bar, reduce to 1/3 cup.
2 large eggs
Eggs bind the ingredients. For a fluffier bar, use room-temperature eggs; for a denser bar, use cold.
2 teaspoons vanilla extract
Pure vanilla extract gives the best flavor. You can use imitation vanilla in a pinch, but reduce to 1 teaspoon.
2 cups (250g) all-purpose flour
All-purpose flour provides structure. For a gluten-free version, use a 1:1 gluten-free baking flour blend.
1 teaspoon baking soda
Baking soda helps the bars rise slightly. If you're out, substitute 1 teaspoon baking powder but expect a slightly different texture.
1/2 teaspoon salt
Salt balances sweetness. Use fine sea salt; if using kosher, increase to 3/4 teaspoon.
2 cups (340g) semisweet chocolate chips
Semisweet chips are classic. Swap for milk chocolate for a sweeter bar, or dark chocolate for a richer flavor.
Tips & Tricks
- Line your baking pan with parchment paper, leaving overhang on two sides. This makes lifting the bars out a cinch and prevents sticking.
- Don't overmix the batter once you add the flour—stir just until no streaks remain. Overmixing develops gluten and makes the bars tough.
- Use a light-colored metal pan, not glass or dark nonstick, for even baking. Glass can over-brown the edges before the center sets.
- Let the bars cool completely before slicing. Use a sharp knife and wipe it clean between cuts for neat, bakery-style squares.
Pro Tips
Step-by-Step Instructions
1. Preheat and Prep Pan
Preheat your oven to 350°F (177°C). Line a 9×13-inch (23×33 cm) baking pan with parchment paper, leaving overhang on two sides. This will make lifting the bars out super easy later.
2. Mix Wet Ingredients
In a large mixing bowl, whisk the melted butter, brown sugar, and granulated sugar until smooth and glossy. Make sure the butter isn't too hot—warm, not boiling—so you don't scramble the eggs.
3. Add Eggs and Vanilla
Beat in the eggs one at a time, then add the vanilla extract. Mix until the batter is pale and slightly thickened, about 1 minute. This aerates the mixture for a lighter texture.
4. Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, and salt. This ensures even distribution of leavening and prevents clumps.
5. Fold in Flour and Chips
Gently fold the dry ingredients into the wet mixture using a spatula. Stir just until no streaks of flour remain, then fold in the chocolate chips. Don't overmix—you want a tender crumb.
6. Spread Batter in Pan
Scrape the batter into the prepared pan and spread it evenly with a spatula. The batter will be thick, so press it into the corners. If you want, sprinkle a few extra chocolate chips on top.
7. Bake Until Golden
Bake for 25-30 minutes, or until the top is golden brown and the edges are set but the center still jiggles slightly. A toothpick inserted in the center should come out with a few moist crumbs, not wet batter. The internal temperature should reach 200°F (93°C).
8. Cool and Slice
Let the bars cool in the pan on a wire rack for at least 20 minutes. Then lift them out using the parchment overhang and transfer to a cutting board. Slice into 24 squares (or 12 larger bars).
Delicious Variations
Double Chocolate
Replace 1/4 cup of the flour with 1/4 cup unsweetened cocoa powder and add an extra 1/2 cup white chocolate chips.
Nutty Crunch
Stir in 1 cup toasted pecans or walnuts along with the chocolate chips for added texture and flavor.
Salted Caramel
Swirl 1/2 cup caramel sauce into the batter before baking and sprinkle with flaky sea salt right after they come out of the oven.
How to Store Best Things For Bake Sale
Refrigerator
Store in an airtight container at room temperature for up to 5 days. For longer freshness, keep them in the fridge for up to a week.
Freezer
Wrap individual bars in plastic wrap and place in a freezer-safe bag. Freeze for up to 3 months. Thaw at room temperature for 30 minutes.
Reheating
To revive that fresh-baked taste, microwave a bar for 10-15 seconds or reheat in a 300°F (150°C) oven for 5 minutes.
Frequently Asked Questions
Q: Can I use salted butter instead of unsalted?
Yes, you can use salted butter, but reduce the added salt to 1/4 teaspoon to avoid overly salty bars. The butter's salt content varies by brand, so taste the batter if you're unsure.
Q: How do I know when the bars are done?
The bars are done when the top is golden brown, the edges are set, and a toothpick inserted in the center comes out with a few moist crumbs. The internal temperature should read 200°F (93°C). Overbaking will make them dry.
Q: Can I make these ahead of time?
Absolutely! These bars actually taste better the next day as the flavors meld. Bake them up to 2 days in advance and store in an airtight container. They also freeze beautifully for up to 3 months.
Q: Can I use a different size pan?
You can use a 9×9-inch pan for thicker bars, but increase the baking time by 5-10 minutes. For a half-sheet pan, reduce baking time to 15-20 minutes. Keep an eye on them and adjust accordingly.
Q: Why did my bars turn out dry?
Dry bars usually mean they were overbaked. Remember to pull them out when the center still looks slightly underdone—it will set as it cools. Also, measure your flour correctly by spooning it into the cup and leveling off.
