Why I Like This Recipe
Wasn’t planning dessert, but yeah — it just kinda happened. Had some strawberries that were too soft to snack on, and ice cream in the back of the freezer. Threw together a quick sauce and layered it all up. Way too good for how easy it is. Zero fancy steps. Just chill, pour, scoop, and done.
Ingredients
For the strawberry sauce:
- 1¼ cup strawberries, hulled + quartered
- 3 tbsp sugar
- 2 tbsp water
- 1 tsp cornstarch
- 1 tsp lemon or lime juice
For the sundaes:
- vanilla ice cream
- whipped cream
- fresh strawberries (extra, optional)
- sprinkles (optional)
How To Make Strawberry Sundae
- Make the sauce: Mix cornstarch + water in a small pan — make sure it dissolves. Add strawberries, sugar, lemon juice. Stir it up.
- Cook it down: Medium heat. Stir here and there. After ~7–8 mins, it should thicken and the strawberries go soft. Mash a few if you want it chunky. Let it cool for a few.
- Layer the sundae: Spoon some warm sauce into a cup or bowl. Add a scoop of vanilla ice cream. More sauce. Another scoop. Top with whipped cream, sprinkles, fresh berries — or just leave it plain.
- Serve: Eat it right away. Melts fast. No notes.

Tips for Success
- Sauce gets thicker as it cools — don’t overcook.
- Use fresh strawberries for best flavor.
- Make the sauce ahead and chill if you want a cold version.
- Cheap ice cream works fine.
- You can double the sauce and keep in the fridge for other stuff (pancakes, waffles, whatever).
Storage and Reheating
- Sauce (fridge): Lasts up to 5 days in a sealed jar. Reheat gently on the stove or microwave in 15-second bursts.
- Ice cream (obviously): Keep frozen. Assemble sundaes fresh. You can’t really store a made sundae.
Frequently Asked Questions
- Can I use frozen strawberries?
Yep. Just thaw first. May take longer to cook down. - Do I need cornstarch?
It helps thicken the sauce. You could skip it, but it’ll be runnier. - Best ice cream brand?
Whatever you like. McDonald’s isn’t premium, so you don’t need anything fancy. - Can I batch the sauce for later?
Definitely. It keeps well in the fridge for a few days. - Is this super sweet?
It’s dessert — yeah, kinda. But the lemon helps balance it out.
Common Mistakes and How to Dodge Them
- Overcooking the sauce: Once it thickens, take it off the heat. Too long and it turns jammy.
- Using underripe berries: They just don’t soften right or taste sweet. Go for ripe or slightly overripe ones.
- Skipping the cornstarch step: Don’t just dump it in dry. Mix with water first or it clumps.
- Assembling early: Don’t do it ahead. Ice cream melts fast, and you lose the layered look.
- Forgetting to taste the sauce: Sometimes strawberries aren’t sweet enough. Taste and add a bit more sugar if needed.
