School Fundraiser Brownies (Makes 48)
My kids’ school knows me by name at the bake sale table. I have made forty-eight brownies the night before three years running. The school fundraiser brownies are the ones that sell out before noon.
There is an art to bake sale baking and it is not what people think. It’s not about making the fanciest thing. It’s about making the thing that sells. The thing that sells at a school bake sale is the thing that looks good in a plastic bag at six feet away, smells like chocolate when someone gets close, is sized right for one person to eat and not feel like they just made a decision, and is priced in a way that makes five-dollar bills easy to spend. These brownies are engineered for all of it.
Brownies for a crowd start with a full sheet pan. Forty-eight portions from one pan, one batch of batter, one hour of your Wednesday night. Fudgy, not cakey. Dense without being gummy. Cut in uniform squares, wrapped individually, and priced at two dollars each. They go first. Every year, same result.
I’m telling you right now: if you’re the parent assigned to the bake sale, bring these. The school will remember you. In the best possible way.
Why This Recipe Works
Most from-scratch large-batch brownie recipes overcorrect on one dimension — too cakey trying to be fancy, or too fudgy and impossible to bag without sticking, or too sweet in a way that doesn’t survive a plastic bag for three hours. These brownies find the middle.
Butter-based, not oil-based. Butter gives a richer flavor and slightly firmer set that makes clean cuts possible. Oil gives a moist brownie that sticks to everything and doesn’t hold its shape in a bag. For easy brownie school bake sale purposes, butter wins.
Two types of chocolate: cocoa powder for depth and intensity, plus melted chocolate chips for the fudgy richness that makes people reach for a second bag. One or the other gives you a good brownie. Both together give you the one that sells out before noon.
Ingredients
Sheet Pan Brownies (Makes 48)
- 2 cups (4 sticks) unsalted butter
- 4 cups granulated sugar
- 8 large eggs
- 2 tbsp vanilla extract
- 2 cups all-purpose flour
- 1½ cups unsweetened cocoa powder
- 1 tsp baking powder
- 1½ tsp salt
- 2 cups semi-sweet chocolate chips (half melted into batter, half stirred in whole)
For the Sale
- Plastic sandwich bags or small cellophane bags
- Stickers or tape for sealing
- Price tags or sticky labels
- Wax paper for cutting surface
How to Make It
1
1Prep the pan
Preheat oven to 350°F. Line a half-sheet pan (18×13 inches) with parchment paper, letting it overhang on all sides for easy lifting. Spray lightly with baking spray. The parchment lining is not optional — brownies this size need it to release cleanly and to lift out for cutting.
2
2Melt butter and chocolate
In a large saucepan over low heat, melt butter completely. Remove from heat. Stir in 1 cup of chocolate chips until melted — the residual heat is enough. Add sugar and stir to combine. Add eggs two at a time, stirring well after each addition. Add vanilla and stir until smooth.
3
3Add dry ingredients
Add flour, cocoa powder, baking powder, and salt directly to the saucepan. Stir until just combined — no dry streaks but no overmixing. Fold in the remaining 1 cup of whole chocolate chips. Batter will be thick.

4Spread and bake
Spread batter evenly across the prepared sheet pan. Use an offset spatula to reach corners. Bake for 22–26 minutes, until the top looks set and a toothpick inserted in the center comes out with moist crumbs (not wet batter, not dry). Pull it early — it’s still cooking even out of the oven, honey. Overbaked brownies bag badly and taste wrong at room temperature the next day.

5Cool completely before cutting
Cool in the pan on a wire rack for at least 2 hours. Fully. Not mostly. Warm brownies cut with torn edges and stick to the bag. Cold brownies cut cleanly and bag professionally. For a truly clean cut: refrigerate for 30 minutes after the initial cooling, then cut cold.
6
6Cut and bag
Lift the entire sheet by the parchment overhang onto a large cutting board. Cut into 8 rows of 6 — 48 uniform squares. Use a sharp knife and wipe clean between cuts for even edges. Bag individually in sandwich bags. Seal with a sticker or fold of tape. Label with price. Stack in a flat box for transport.
Things I’ve Learned From Making This Too Many Times to Count
Refrigerate before cutting. This is the thing I had to learn the hard way in my own kitchen — the first year I cut them warm and spent twenty minutes cleaning brownie edges off my knife. Cold brownies cut like a dream. Put the cooled pan in the refrigerator for 30 minutes before cutting. It changes everything.
Uniform sizing matters. Uneven squares look amateur at a bake sale table. Use a ruler for your first few cuts. Eight rows of six gives exactly 48 even pieces from a half sheet pan. Uniform pieces at a uniform price — that’s the display that sells everything.
The difference between good and gone-in-ten-minutes is right here: label every bag with the price before you leave the house. Bake sale setup is chaotic. Pre-priced bags mean you set them out and they’re ready. Unlabeled bags mean you’re writing prices with a marker at 8:15 a.m. in front of parents who are already running late.
Pack flat. Brownies in a zip bag can travel stacked two-deep if separated by a piece of parchment in the box. More than two and the bottom ones get compressed. Pack flat with parchment between layers for a clean arrival.
Bake the night before. Morning-of baking means warm brownies. Warm brownies don’t cut cleanly. Night-before brownies are fully cooled, easy to cut, and bagged before anyone wakes up. That is the whole schedule.
What to Serve With School Fundraiser Brownies
At a bake sale table, these look best when surrounded by other baked goods in a similar price range. A plate of chocolate chip cookies and a tray of the cream cheese brownies alongside creates visual variety while keeping everything in the same impulse-buy territory. The goal is a table people stop at, not pass by.
For a class party or room party context — where the brownies are served rather than sold — cut them slightly larger (6×4 = 24 pieces) and serve on a platter with napkins. They don’t need anything else. They’re complete.
Variations Worth Trying
Cream cheese swirl. Mix 8 oz softened cream cheese with ¼ cup sugar and 1 egg. Drop by spoonfuls over the brownie batter and swirl with a toothpick before baking. More visual, more impressive, same bake time. Prices two dollars higher without complaint.
Peanut butter chips. Swap the whole chocolate chips for peanut butter chips. The base batter stays the same. Different flavor profile, same structure, appeals to peanut butter fans who walk past plain chocolate.
Walnut brownies. Fold in 1 cup of chopped walnuts with the chocolate chips. Classic. Sells well among adults. Check your school’s nut policy before doing this — know your audience.
Holiday version. Scatter holiday-colored M&Ms over the batter before baking. They press in slightly as the brownies bake and give a festive look for winter sales. Simple done right.
Storage and Reheating
Individually bagged brownies keep at room temperature for up to 5 days. For make-ahead: bake, cool, and cut up to 2 days before the sale. Store cut (unbagged) brownies in an airtight container with parchment between layers. Bag the morning of delivery.
Uncut brownies freeze well — wrap the entire sheet in plastic wrap and freeze for up to 2 months. Thaw overnight at room temperature. Cut and bag after thawing.
FAQ
Can I use a 9×13 pan instead of a sheet pan?
Yes — halve the recipe and use a 9×13 pan. Bake time increases to 30–35 minutes for a thicker brownie. A half sheet pan gives 48 thin-to-medium brownies; a 9×13 at half batch gives 24 thicker ones. Both work. The sheet pan is specifically for making 48 units efficiently.
What price should I set for the bake sale?
$2–3 per bagged brownie is the standard range for school fundraisers. At $2, they sell fast. At $3, they still sell fast and raise more money. Price per the school’s guidance, but don’t undervalue the batch. These are real brownies from real butter and real chocolate.
How do I know if they’re overbaked?
The toothpick test is key: moist crumbs clinging to the toothpick = done. Wet batter = not done. Clean toothpick = overbaked. Pull at moist crumbs. The brownies will continue setting as they cool. A dry brownie in the oven becomes a brick at room temperature.
