Ingredients

For the chocolate base:

• 3 cups (18 oz) semi-sweet chocolate chips
• 14 oz sweetened condensed milk (1 standard can)
• 1/4 cup (4 tablespoons) unsalted butter
• 1 teaspoon vanilla extract
• 1/4 teaspoon salt

For the blood moon swirl:

• 1 cup (6 oz) white chocolate chips
• 2 tablespoons sweetened condensed milk
• 1-2 teaspoons red food coloring (gel preferred for intensity)
• 1/4 teaspoon black food coloring (optional, for deeper red)

The semi-sweet chocolate creates the perfect backdrop for our “blood moon” effect, while high-quality white chocolate ensures the red swirls set properly. Gel food coloring provides the most vivid blood-red color without adding excess liquid that could affect the fudge’s texture. For a truly authentic moon appearance, the optional black food coloring adds depth to the red swirls.

Pro Tips

Choose Quality Chocolate: The flavor of your Halloween Blood Moon Fudge depends heavily on your chocolate selection. Higher cocoa content semi-sweet chocolate (around 60%) delivers the richest flavor. Avoid chocolate chips with stabilizers by checking the ingredients list—look for chips with cocoa butter rather than vegetable oils for the smoothest melting.

Master the Swirl Technique: For the most realistic blood moon effect, use a toothpick or skewer to create your swirls. Insert the tool all the way to the bottom of the pan and make deliberate, slow movements in a circular pattern. Don’t over-swirl, as this will muddy the colors—aim for 5-7 strategic swirls for the most dramatic effect.

Perfect Setting Temperature: Allow your fudge to set at room temperature for 30 minutes before transferring to the refrigerator. This gradual cooling prevents condensation and sugar crystallization that can make your fudge grainy. For clean cutting, dip your knife in hot water and wipe dry between slices.

Instructions

Step 1: Prepare Your Pan
Line an 8×8-inch baking pan with parchment paper, leaving overhang on all sides for easy removal later. Lightly mist the parchment with cooking spray to prevent sticking. This preparation ensures your Halloween Blood Moon Fudge will release perfectly after setting.

Step 2: Create the Chocolate Base
In a medium-sized, heavy-bottomed saucepan, combine the chocolate chips, sweetened condensed milk, and butter. Heat over low-medium heat, stirring constantly with a silicone spatula to prevent scorching. Once the mixture is completely smooth with no visible chocolate pieces (about 5 minutes), remove from heat and stir in the vanilla extract and salt. The mixture should be glossy and pull away slightly from the sides of the pan.

Step 3: Pour the Base Layer
Transfer your chocolate mixture to the prepared pan, using your spatula to spread it evenly into corners. Tap the pan gently against the counter several times to release any trapped air bubbles. This creates the smooth “night sky” background for your blood moon effect.

Step 4: Prepare the Blood Moon Swirl
In a microwave-safe bowl, combine white chocolate chips and the remaining 2 tablespoons of sweetened condensed milk. Microwave in 20-second intervals, stirring between each, until completely melted and smooth (usually 60-80 seconds total). Add the red food coloring one teaspoon at a time, stirring thoroughly until you achieve a deep blood-red color. Add the optional black food coloring if using, for a more realistic lunar appearance.

Step 5: Create the Blood Moon Effect
While both chocolate mixtures are still warm, drop spoonfuls of the red white chocolate mixture randomly across the surface of the chocolate base. Using a toothpick or skewer, gently swirl the red mixture into the chocolate base using circular motions to create a moon-like appearance. Focus on creating one larger circular pattern to represent the full blood moon, with smaller swirls around it representing distant stars.

Step 6: Set and Slice
Allow your Halloween Blood Moon Fudge to cool at room temperature for 30 minutes, then transfer to the refrigerator to set completely, about 2-3 hours. Once firm, lift the fudge from the pan using the parchment paper overhang. With a sharp knife warmed under hot water and dried, cut into 1-inch squares for serving. For the most dramatic presentation, arrange pieces with prominent “blood moon” swirls at the center of your display.

Variations

Cookies and Cream Blood Moon: Transform your Halloween Blood Moon Fudge into a graveyard scene by adding 1 cup of crushed chocolate sandwich cookies to the base mixture. Sprinkle additional cookie “dirt” on top after swirling for a spooky cemetery effect beneath your blood moon.

Spiced Blood Moon: Add a warming kick to your fudge by incorporating 1/2 teaspoon of cinnamon and a pinch of cayenne pepper to the chocolate base. This subtle heat enhances the chocolate flavor while creating a surprising sensory experience that complements the Halloween theme.

Vegan Blood Moon Fudge: Create a plant-based version by substituting the sweetened condensed milk with full-fat coconut milk reduced with sugar (simmer 1 can coconut milk with 1/2 cup sugar until reduced by half). Use dairy-free chocolate chips and vegan butter alternatives to maintain the creamy texture while accommodating dietary preferences.

Storage and Serving

Store your Halloween Blood Moon Fudge in an airtight container with parchment paper between layers to prevent sticking. At room temperature, it will remain fresh for 7-10 days, though the texture is best within the first week. For longer storage, refrigerate for up to three weeks or freeze for up to three months (thaw in the refrigerator overnight before serving).

For a spectacular Halloween dessert table, arrange your fudge pieces on a large black platter and surround them with spun sugar “cobwebs” or edible luster dust for an ethereal cosmic glow. Create a mini dessert sampler by pairing small cubes of fudge with fresh berries and a small scoop of vanilla ice cream, topped with a sprinkle of edible gold stars for a complete celestial experience.

For gifting, stack fudge pieces in clear cellophane bags tied with orange and black ribbon, or arrange in small black gift boxes lined with orange tissue paper for a premium Halloween treat.

FAQs

Why did my fudge turn out grainy?
Grainy fudge typically results from sugar crystallization. Prevent this by avoiding rapid temperature changes, stirring gently rather than vigorously, and using room temperature butter. If your Halloween Blood Moon Fudge seems grainy, you can sometimes rescue it by remelting with a tablespoon of heavy cream.

Can I use milk chocolate instead of semi-sweet?
Yes, milk chocolate can be substituted for a sweeter, creamier Halloween Blood Moon Fudge. However, reduce the vanilla to 1/2 teaspoon as milk chocolate has a milder flavor that can be overwhelmed by too much extract.

How can I make the red color more vibrant?
Gel food coloring produces the most intense red for authentic blood moon effects. For an even deeper red, add the coloring to the white chocolate while it’s still warm and let it develop for a few minutes before swirling. Some bakers find that adding a tiny amount of brown or black food coloring creates a more realistic blood-red shade.

Will liquid food coloring work for this recipe?
While gel food coloring is preferred, liquid coloring can work if used sparingly. Add it drop by drop to avoid adding excess moisture that could prevent your fudge from setting properly.

Can I make this fudge without a candy thermometer?
Absolutely! This Halloween Blood Moon Fudge recipe is designed to work without specialty equipment. The sweetened condensed milk ensures proper setting without needing to monitor specific temperatures.
