Step 1: Prepare Your Pan

Line an 8×8-inch square baking pan with parchment paper or aluminum foil, leaving an overhang on two opposite sides for easy removal later. This is important – don’t skip this step or your fudge will stick to the pan. Lightly butter the parchment paper or foil. Set the prepared pan aside.

Step 2: Combine Ingredients

In a heavy-bottomed 3-4 quart saucepan, combine the maple syrup, sugar, and heavy cream. Stir gently with a wooden spoon until the ingredients are mixed together. Don’t worry if the sugar isn’t completely dissolved yet – it will dissolve as the mixture heats.

Step 3: Heat the Mixture

Place the saucepan over medium heat. Stir constantly until the sugar completely dissolves and the mixture comes to a boil. This takes about 5-7 minutes. Once boiling, stop stirring. If you have a candy thermometer, clip it to the side of the pan now, making sure the bulb doesn’t touch the bottom of the pan.

If you notice sugar crystals forming on the sides of the pan, use a wet pastry brush to brush them down into the mixture. This helps prevent crystallization, which can make your fudge grainy.

Step 4: Cook to Soft Ball Stage

Allow the mixture to boil without stirring until it reaches 234-238°F (112-114°C) on a candy thermometer. This is called the soft ball stage and is crucial for proper fudge texture. This typically takes 10-15 minutes of boiling, depending on your stove and pan.

If you don’t have a candy thermometer, you can test by dropping a small amount of the mixture into a cup of cold water. At soft ball stage, it will form a soft, pliable ball that flattens when removed from the water. It should hold its shape but be easily moldable.

Watch the mixture carefully during the last few minutes of cooking. The temperature can rise quickly at the end, and going past soft ball stage will result in harder, more brittle fudge.

Step 5: Add Butter and Cool

Once the mixture reaches the proper temperature, immediately remove the pan from heat. Add the butter pieces and the pinch of salt (if using) but do NOT stir yet. Let the mixture cool undisturbed until it reaches 110°F (43°C). This cooling period takes about 45-60 minutes and is essential for achieving smooth, creamy fudge. Don’t rush this step by placing the pan in cold water or refrigerator – slow cooling at room temperature is important.

Step 6: Beat the Fudge

Once cooled to 110°F (or when you can comfortably hold your hand against the bottom of the pan), add the vanilla extract. Now begin beating the mixture vigorously with a wooden spoon. This is where the magic happens! As you beat, the fudge will gradually lose its glossy appearance and become lighter in color and thicker in texture. This process takes 5-10 minutes of continuous beating. Your arm will get tired – that’s normal!

The fudge is ready when it starts to lose its shine, becomes noticeably thicker, and begins to hold its shape when you lift the spoon. It should still be pourable but will have transformed from a thin syrup to a thick, creamy mixture.

Step 7: Pour and Spread

Immediately pour the beaten fudge into your prepared pan. Work quickly because the fudge will continue to set as you work. Use a buttered knife or offset spatula to spread it evenly into the corners and smooth the top. Don’t worry about making it perfectly smooth – a slightly rustic look is charming.

Step 8: Cool and Cut

Let the fudge cool completely at room temperature. This takes at least 2 hours, though overnight is even better. The fudge needs to set fully before cutting. Once completely set, use the parchment paper overhang to lift the entire slab of fudge out of the pan. Place it on a cutting board.

Using a sharp knife, cut the fudge into squares. For small candy-sized pieces, cut into 1-inch squares (8 rows by 8 rows = 64 pieces). For larger serving pieces, cut into 1.5-inch squares (about 6 rows by 6 rows = 36 pieces). Wipe your knife clean between cuts for the neatest edges.
