My homemade hot fudge sauce has an intense chocolate flavor without being overly sweet, and a silky, pourable consistency that makes it perfect for drizzling over ice cream. Unlike chocolate syrup, this fudge topping has a more substantial texture thanks to unsweetened chocolate.

Skill Level: Beginner
Flavor Remix: Add a little espresso powder to deepen the chocolate flavor, or swap the vanilla for peppermint extract for a mint chocolate version.
Allergy Watch: Naturally gluten-free, nut-free, and egg-free.
There is a fine line between a hot fudge sauce that tastes like chocolate and one that tastes mostly like sugar. Using unsweetened baking chocolate gives this version a robust chocolate flavor while letting you control the sweetness.
The secret is butter and chocolate melting together into a smooth base before adding the half and half. I found that this order makes it much easier to emulsify the dairy into the chocolate mixture, creating a silky sauce rather than one that looks separated or oily.
And while homemade hot fudge will become almost solid as they cool, this recipe has a lovely pourable consistency when warm. It is just right for spooning over a scoop of frozen vanilla custard, drizzling on brownies, or dressing up a bowl of strawberries.

Ingredient Notes
- Chocolate: Use 100% unsweetened baking chocolate, sometimes labeled baker's chocolate. This is NOT the same as bittersweet or semisweet chocolate.
- Half and Half: If you don't have half and half, substitute ⅔ cup whole milk and ⅓ cup heavy whipping cream for the 1 cup called for in the recipe.
- Sugar: You can vary the sugar to your liking; try no more than a ¼ cup up or down
- Butter: Use salted butter or increase the salt added by ¼ teaspoon.
- Vanilla Extract: Or use an equal amount of vanilla paste.
How to Make Hot Fudge
A step-by-step visual guide for making homemade chocolate sauce. You can skip to the recipe for the full written instructions.

Melt the Chocolate
Melt low and slow with the butter so it doesn't scorch.

Boil
Increase the heat to medium and stir constantly as the mixture heats. You want a gentle boil rather than a vigorous one.

Season to Taste
Whisk in the salt and vanilla. Adjust the sugar (will need to simmer again) and salt to taste.
Jen's Recipe Notes
- Keep the heat low in the beginning. Unsweetened chocolate can scorch, especially when melted directly in a saucepan.
- Unsweetened baking chocolate is essential for getting that bold chocolate flavor without an overly sweet finish. Substituting semisweet chocolate will significantly change the balance.
- Stir constantly once you increase the heat so the sauce doesn't stick to the bottom of the saucepan as it approaches a boil. A whisk helps keep everything moving.
- Remember that hot fudge thickens as it cools. Judge the final pouring consistency when the sauce is warm rather than straight from the refrigerator. If refrigerated sauce is too thick to pour, gently warm it while stirring.

Make Ahead and Storing
Make Ahead: Prepare the hot fudge sauce up to 1 week in advance. Store in a clean, airtight glass jar in the refrigerator until ready to serve.
Storing: Refrigerate leftover sauce in an airtight container for up to 1 week. To reheat, microwave in 15 to 20 second intervals, stirring between each, until warm and pourable. You can also warm it in a small saucepan over low heat.
Freezing: Freeze in a freezer safe, airtight container for up to 3 months, leaving a little room for expansion. Thaw overnight in the refrigerator, then reheat gently, stirring until smooth.
