Enter the number of servings you plan to serve. This brownie platter calculator allows 2 brownies and 15 grams of chocolate per serving, so a brownie platter for a party is easy to plan. For 20 servings, you need 40 brownies and 300 grams of chocolate. For 10 servings, you need 20 brownies and 150 grams of chocolate. For 25 servings, you need 50 brownies and 375 grams of chocolate. Brownies and chocolate scale in direct proportion, and the pan yield section below turns those totals into 8x8, 9x13, and sheet pan batches, plus kids portions, dessert table rules, and a shopping list.
Type in servings, and the calculator returns two numbers: brownies as a count and chocolate in grams. The maths is simple and shown openly, so you can check it by hand. Brownies equal servings times 2, and chocolate equals servings times 15 grams. A serving here means one guest at a standard party spread, with brownies as one dessert among others, not the only dessert. The 2 brownies per serving covers a guest taking two small pieces, or one standard piece plus a second taste.
Advice on brownies per person varies, which is why a calculator helps. Dessert guides that count every dessert together often suggest 1 brownie per person, or 1.5 dessert servings per person in total across all desserts. Party guides for kids parties suggest 2 brownies per person, because children treat brownies as the main event. This calculator uses 2 brownies per serving as its standard, which sits at the generous end and avoids running out. If brownies share the table with cake, ice cream, and cookies, enter a lower servings number, or accept that some brownies will be left over. If brownies are the only dessert, 2 per person is exactly right, and for a very hungry crowd you can raise the servings number by about a quarter.
Pan size decides how many batches you must bake. An 8x8 pan makes about 16 brownies when cut into 4 rows by 4 rows. A 9x13 pan makes about 12 generous brownies, or up to 24 small brownies, depending on how you cut it. A sheet pan makes about 30 to 36 brownies, which suits a crowd. Turn a calculator total into batches by dividing by the pan yield: 40 brownies for 20 guests means about 3 batches from an 8x8 pan, 2 batches from a 9x13 pan cut small, or just over 1 batch from a sheet pan. For 100 guests, 200 brownies mean about 13 batches from an 8x8 pan, or about 6 sheet pan batches. Baking in a sheet pan is the simplest route for a crowd, because fewer batches means less oven time and more even cutting.
Use this table to shop at a glance. For 10 guests: 20 brownies and 150 grams of chocolate. For 20 guests: 40 brownies and 300 grams of chocolate. For 25 guests: 50 brownies and 375 grams of chocolate. For 50 guests: 100 brownies and 750 grams of chocolate. For 100 guests: 200 brownies and 1500 grams of chocolate. Add a buffer of about 10 percent for breakage and for guests who take a third piece, which turns 40 brownies into 44 and 100 brownies into 110. Rounding up to the next full pan batch is the simplest way to apply that buffer.
Plan 15 grams of chocolate per serving. That covers chocolate melted into the batter plus a small amount for drizzling or for chocolate chips on top, which is the part most brownie guides leave unquantified. For 20 guests, that is 300 grams, or 3 standard 100 gram bars. For 50 guests, it is 750 grams. For 100 guests, it is 1500 grams, or 1.5 kilograms. Buy one extra bar beyond the calculator total for a crowd, because chocolate is cheap insurance against a batch that needs a little more. Dark, milk, or semi sweet chocolate all work, but keep one type across all batches so the platter tastes consistent.
Kids at a birthday party eat about 2 brownies each, which is the calculator standard, and mini brownies change the count: plan 3 to 4 mini brownies per person, because small pieces disappear fast. A wedding dessert table needs 1 to 2 brownies per person, because cake is usually served too, so the calculator total is a safe upper amount. An office party needs the standard 2 per person, with a mix of plain and nut topped brownies. A bake sale is different: brownies are sold, not served, so plan by pieces for sale, using the calculator total as the batch target and wrapping pieces individually. A brownie dessert table where brownies stand alone needs the full 2 per person, plus a second dessert for guests who cannot eat chocolate.
Your brownie platter shopping list starts with the calculator totals, then adds the baking basics. For 20 guests, the list is 40 brownies worth of batter, 300 grams of chocolate, butter, sugar, eggs, and flour for about 2 to 3 batches, plus parchment paper and one platter or board per 40 pieces. Brownies keep well: store them in an airtight container for 3 to 4 days at room temperature, or freeze them for up to 3 months and thaw on the day. Cut brownies on the day when you can, so the edges stay neat, and dust with cocoa or powdered sugar just before serving for a clean finish.
Plan 2 brownies per person for a standard party. That is the calculator default: 2 brownies and 15 grams of chocolate per serving.
For 20 guests you need 40 brownies and 300 grams of chocolate. For 50 guests you need 100 brownies and 750 grams of chocolate.
About 12 generous servings, or up to 24 small servings, depending on how you cut the pan. An 8x8 pan makes about 16 brownies.
About 30 to 36 brownies, which makes a sheet pan the simplest choice for a crowd of 50 or more guests.
Plan 15 grams of chocolate per serving, covering batter chocolate plus a little for drizzling or chips on top.
Serve 2 per person when brownies are a main dessert, and 1 per person when cake and other desserts share the table. The calculator uses 2 as its standard.
Plan 2 standard brownies per child, or 3 to 4 mini brownies per child, because small pieces are eaten in larger numbers.
Use the calculator total as your batch target, then wrap pieces individually. For 50 buyers, plan 100 brownies, plus a few extra for breakage.
Yes. Plan 1 to 2 brownies per guest alongside cake, and use the calculator total as a safe upper amount so the table does not run out.
Multiply the per serving amounts: brownies equal servings times 2, and chocolate equals servings times 15 grams. Then divide by your pan yield to get batches.
Brownies keep 3 to 4 days in an airtight container at room temperature, and up to 3 months in the freezer. Cut them on the day for neat edges.
