Creamy, cold, and piled high with glossy homemade sauce, these Strawberry Sundaes are the kind of dessert that makes everyone stop talking at the dinner table. I started making these after one summer afternoon when the strawberries from the market were so ripe they practically begged to become a sauce, and I knew plain ice cream wasn't going to cut it. The whole thing comes together in 25 minutes with everyday ingredients, and the result honestly tastes like something from an old-school ice cream parlor.


If you love fruity, creamy desserts, you might also want to peek at my Peach Pie Crumb Bars or these dreamy Tiramisu Crepe Cakes, both hit that same sweet, nostalgic note. And for a cozy pairing on a different kind of day, my Marshmallow-Surprise Hot Cocoa Cookies are always nearby in this kitchen.

See Recipe Card Below This Post For Ingredient Quantities
For the Strawberry Sauce
- Strawberries , cut into ½-inch slices: These are the heart of the sauce. Fresh, ripe strawberries give you the best flavor and that beautiful deep-red color once they cook down.
- Granulated sugar : Sweetens the sauce and helps the berries release their juices as they cook.
- Lemon juice : Brightens the whole sauce and keeps the strawberry flavor tasting fresh, not flat.
- Water : Helps the mixture come to a simmer without scorching before the berries soften.
- Water : This small amount is mixed with the cornstarch to make a slurry that thickens the sauce smoothly.
- Cornstarch : The secret to that glossy, spoonable texture. Mix it with a little water before adding it to the hot pan.
For the Strawberry Sundaes
- Vanilla ice cream : Classic and creamy, it's the perfect backdrop for the bright strawberry sauce. Use your favorite brand.
- Chopped nuts : Adds a little crunch and a nutty contrast to all that soft, creamy sweetness.
- Strawberries, sliced : Fresh berries on top add color and a clean, fruity bite.
- Sprinkles: Totally optional but completely necessary if kids are involved.
- Whipped cream: A generous cloud on top pulls the whole sundae together.
How to Make Strawberry Sundaes
Here's a simple, step-by-step guide, no experience needed.
Prepare the strawberries: Wash and dry your strawberries, then cut off the green tops and slice them into ½-inch pieces. Add the 1 pound of sliced strawberries to a medium saucepan along with the granulated sugar, lemon juice, and ¼ cup of water. Set it over medium-high heat.

Cook the strawberry mixture: Stir the mixture to help the sugar start dissolving. Bring it to a boil, then lower the heat to keep a gentle simmer going. Let it simmer, stirring occasionally, for 3 to 4 minutes until the strawberries are tender but still holding their shape. They'll smell amazing at this point.
Make the cornstarch slurry: In a small bowl, stir together the cornstarch and the remaining 1 tablespoon of water until the cornstarch is fully dissolved and smooth. No lumps.
Thicken the sauce: Pour the cornstarch slurry into the saucepan and stir gently to combine. Keep simmering for 1 to 2 minutes, stirring occasionally. Watch for the sauce to turn glossy and noticeably thicker. Once it does, turn off the heat.

Adjust the flavor: Give the sauce a taste. If it needs a little brightness, squeeze in a touch more lemon juice.
Cool the sauce: Let the strawberry sauce sit and cool for at least 10 minutes. It thickens up more as it cools, so don't skip this step, even if you're impatient.
Assemble the sundaes: Spoon a layer of strawberry sauce into the bottom of each of your 4 sundae cups or glasses. Add a scoop of vanilla ice cream on top, then spoon more sauce generously over the ice cream.
Garnish and serve: Finish each Strawberry Sundaes with chopped nuts, fresh sliced strawberries, whipped cream, and a handful of sprinkles. Serve right away while the ice cream is still cold and firm.
Substitutions
Strawberries: Frozen strawberries work in a pinch for the sauce. Thaw them first and drain excess liquid. For the fresh garnish on top, try raspberries or sliced peaches if strawberries aren't in season.
Granulated sugar: Swap in coconut sugar or light brown sugar for a slightly deeper, more caramel-tinged sweetness in the sauce.
Vanilla ice cream: Strawberry ice cream doubles down on the berry flavor. Coconut ice cream makes this dairy-free.
Chopped nuts: Leave them out for nut allergies, or swap in toasted coconut flakes for a tropical crunch.
Cornstarch: Arrowroot powder works as a 1:1 substitute if that's what you have on hand.

Storage Tips For Strawberry Sundaes
Strawberry sauce: Store leftover sauce in an airtight container or jar in the refrigerator for up to 5 days. It thickens quite a bit when cold, so warm it gently in the microwave or on the stovetop with a splash of water to loosen it up before serving.
Assembled Strawberry Sundaes: These are best eaten right away. Once built, the ice cream melts fast, so don't let them sit.
Freezer note: The sauce does not freeze especially well since the texture can turn watery after thawing. Fresh is best here.
Serving Suggestions
Afternoon treat for kids: Set up a little topping station with nuts, sprinkles, and extra berries and let the kids build their own. It turns into a whole activity.
Casual summer dinner party: Make the sauce ahead, refrigerate it, then set it out with a tub of ice cream and toppings so everyone can help themselves. Low effort, big impression.
Weekend brunch dessert: These pair beautifully after something like a stack of pancakes or French toast. The fruity brightness cuts through a rich brunch spread nicely.
Double berry moment: Serve alongside my Strawberry Nutella Cupcakes for a full strawberry dessert spread that nobody will argue with.
Expert Tips
Warm your topping slightly. Slightly warm strawberry sauce over cold ice cream creates the most satisfying contrast. Just a quick 20-second microwave reheat does it.
Don't skip the cooling time. The sauce looks a little loose right off the stove, but it firms up noticeably as it cools. Give it the full 10 minutes.
Use ripe strawberries. The flavor of the sauce depends on the fruit. Pale, underripe berries will give you a bland sauce no matter how much sugar you add.
Sauce in the bottom is the move. Adding a layer of sauce to the bottom of the cup before the ice cream means every single bite has sauce from start to finish.
Make the sauce ahead. The sauce keeps beautifully in the fridge for up to 5 days, which makes these Strawberry Sundaes weeknight-quick whenever a craving hits.
FAQ
How do you make a Strawberry Sundaes from scratch?
Start by making a simple homemade strawberry sauce with fresh strawberries, sugar, lemon juice, water, and a cornstarch slurry to thicken it. Once the sauce cools for about 10 minutes, layer it into a cup with vanilla ice cream, then top with whipped cream, nuts, fresh berries, and sprinkles. The whole thing takes about 25 minutes. My tip: let the kids add their own toppings. It makes the whole experience more fun.
What is the best strawberry sauce for ice cream?
A cooked fresh strawberry sauce using ripe berries, a little sugar, lemon juice, and cornstarch gives you the best result. It turns thick, glossy, and deeply flavored, not thin or syrupy like the jarred versions. The lemon juice is key, it keeps the sauce tasting bright and fresh rather than heavy and one-note.
Can I make Strawberry Sundaes sauce ahead of time?
Yes, and it's actually one of the best things about this recipe. Make the sauce up to 5 days in advance and store it in a jar in the fridge. When you're ready to serve, warm it gently and it's good to go. It's a great trick for summer gatherings.
How long does homemade strawberry sauce last?
Stored in an airtight container in the refrigerator, homemade strawberry sauce stays fresh for up to 5 days. Give it a good stir after it's been in the fridge since it thickens quite a bit when cold. If it seems too thick, a tiny splash of warm water stirred in will loosen it right up.
