Salted Caramel Butter Fudge

Salted Caramel Butter Fudge is the kind of treat that instantly feels indulgent, yet surprisingly simple to make. First, it melts together rich butter and golden caramel into a silky base. Then, a sprinkle of flaky sea salt balances the sweetness beautifully. As a result, every bite tastes creamy, smooth, and deeply buttery.

Although fudge has been around since the late 1800s, salted caramel is a more modern favorite. Interestingly, French pastry chefs popularized salted caramel in the 1970s. Since then, it has become a global dessert obsession. Therefore, combining it with classic butter fudge creates something timeless and trendy all at once.

Moreover, this homemade fudge sets perfectly with minimal effort. It slices cleanly, holds its shape, and tastes bakery-worthy. Whether you’re gifting it or serving it at gatherings, this Salted Caramel Butter Fudge delivers rich flavor and irresistible texture in every square.

Recipe Yield: 25 servings

INGREDIENTS

1 cup unsalted butter
2 ½ cups granulated sugar
¾ cup heavy cream
½ cup light corn syrup
½ tsp fine sea salt
1 ½ tsp pure vanilla extract
½ cup thick caramel sauce (high quality)
½ tsp flaky sea salt (for topping)

INSTRUCTIONS

1. Prepare the pan: Line an 8×8-inch baking dish with parchment paper, leaving overhang on two sides for easy removal.

2. Cook the base:
In a heavy saucepan over medium heat, melt butter completely. Then add sugar, heavy cream, and corn syrup. Stir continuously until sugar dissolves. Bring mixture to a steady boil. Continue cooking, stirring frequently, until a candy thermometer reaches 234–236°F (soft-ball stage). Remove from heat.

3. Add flavor:
Immediately stir in fine sea salt, vanilla extract, and caramel sauce. Mix until smooth and glossy.

4. Beat for texture:
Allow mixture to cool for 5 minutes. Then beat vigorously with a wooden spoon for 3–4 minutes until slightly thickened and less shiny.

5. Pour and set:
Quickly pour into prepared pan and smooth the top. Sprinkle flaky sea salt evenly over surface.

6. Chill and slice:
Let set at room temperature for 3 hours, or refrigerate for 1 hour. Lift out using parchment and cut into squares.

Helpful Tips to Perfect This Recipe

• Use a Candy Thermometer for Accuracy: Because fudge texture depends on precise temperature, reaching 234–236°F ensures the perfect soft yet sliceable consistency. Otherwise, it may turn grainy or overly soft.
• Beat at the Right Time: After cooling slightly, beating the mixture helps create that classic creamy texture. However, beating too early can make it dull and crumbly, so timing matters.
• Choose Quality Caramel Sauce: Since caramel is the star flavor, use a thick, high-quality sauce. Consequently, the flavor becomes richer and more balanced with the sea salt finish.
