A sundae bar is a favorite at graduations, birthdays and summer weddings in the Chicago suburbs. It is simple food and a big hit, but ice cream melts quickly and a line of kids with open scoops makes a mess. A little equipment goes a long way. Here is the plan.

How much ice cream

Gallons of ice cream by guest count Bar chart of gallons of ice cream: 1 gallon for 25 guests, 2 gallons for 50, 3 to 4 gallons for 100, and 6 gallons for 150 guests, based on a 4 ounce scoop and some seconds. 123.56 2550100150 gallons
Gallons by guest count, with a cushion for seconds.

A gallon holds 128 ounces, which is about 30 scoops of 4 ounces. For a sundae with 2 scoops, double the numbers. Ice cream is sold in 3-gallon tubs for scoop shops and in smaller tubs for home use; ask where you are buying.

Toppings that cover everyone

  • Sauces: chocolate, caramel, strawberry
  • Crunch: crushed cookies, sprinkles, chopped nuts (label them), granola
  • Fruit: strawberries, bananas, cherries
  • Candy: mini chocolate chips, gummies, marshmallows
  • Cream: whipped cream in a can, kept on ice

Count about 1.5 tablespoons per topping per guest. Keep nut toppings on their own table with their own spoon, and label them. See dessert table equipment for stands and layout.

Keeping ice cream frozen

  1. 1Step 1Freeze the tubsovernight and bring them in the last 30 minutes.
  2. 2Step 2Pack in a coolerwith dry ice or lots of ice and salt.
  3. 3Step 3Scoop from one tubat a time and keep others closed.
  4. 4Step 4Dip the scoopin a bucket of warm water to scoop cleanly.
  5. 5Step 5Return melted ice creamto the trash; never refreeze.

Dry ice is very cold and can burn skin. Wear gloves, keep it away from children and never seal it in an airtight container. Ask the supplier for handling tips. Ice cream is also a temperature-controlled food, so follow the guidance in food safety at home parties. For general cooler tips, see keeping food cold at outdoor events.

Layout and flow

Run the bar as one direction line: bowls, ice cream, toppings, spoons and napkins. Put it at least 6 feet from the main buffet. An attendant to scoop avoids drips and keeps portions even, and works well for 75 or more guests. Put a trash can and wet wipes by the exit of the line, and a cloth on the floor under the toppings.

Plan seating: guests eat a sundae in 10 to 15 minutes standing or sitting. A few high-top or cocktail tables and some benches are enough, and you can use garden folding chairs for casual yard parties.

Mistakes that cause messes

  • One long table. Guests who stop to think about toppings block everyone behind them. Split ice cream and toppings onto two tables so two people can build at once.
  • Bowls too small. A 4-ounce cup fills with one scoop and no room for toppings. Use 6 to 8-ounce bowls.
  • Flimsy spoons. Frozen ice cream snaps cheap plastic spoons. Buy sturdy ones or use metal.
  • No spill plan. Sticky sauce on a linen cloth is hard to clean. Use a plastic-lined table or a wipeable cover, and keep a roll of towels and a bin close.
  • No allergy sign. Cookie pieces, nuts and some sauces contain common allergens, so write the contents on a small card.

Chicago notes

On a hot July day, a sundae bar may be gone in 30 minutes, so serve in waves and add a second tub to the freezer. Many Chicago-area ice cream shops will sell tubs in bulk or provide a catering service, but we do not endorse specific shops. In winter, a sundae bar is a fun inside treat; the same freezer rules apply when the room is warm.

Frequently asked questions

How much ice cream per person for a sundae bar?

About 4 ounces, or one scoop, for a light dessert. For a full sundae with two scoops, plan 8 ounces. A gallon makes roughly 30 scoops.

How many flavors should I offer?

Two or three for 50 guests, and three or four for 100. Vanilla and chocolate cover most guests.

How do I keep ice cream from melting at a party?

Freeze tubs overnight, keep them in a cooler with dry ice or packed ice until serving, and scoop from one tub at a time.

How many toppings do I need?

Eight to ten, with sauces, crunch, fruit and candy. Keep nuts separate and labeled.

Do I need an attendant?

For 75 or more guests, yes. It speeds the line and prevents melted drips.

Can I do a sundae bar outdoors in summer?

Yes, in shade, with a small amount of ice cream out at a time. Replace tubs from the cooler every 20 to 30 minutes.
