Start by measuring out all the ingredients you’ll need for the Grinch fudge.
In a medium bowl, stir together the condensed milk, vanilla extract, and green food coloring.
Mix with a silicone spatula until smooth and well combined.
Fill a pot about ⅓ full with water and bring it to a simmer, then reduce the heat to low.
Set a large glass or metal bowl on top of the pot, making sure the bottom of the bowl doesn’t touch the water.
Add the condensed milk, butter, and white chocolate chips to the bowl.
Stir regularly as everything melts.
Keep mixing until the mixture is completely melted and silky smooth.
Line a baking pan with parchment paper, then pour in the fudge mixture.
Spread it evenly with a clean silicone spatula.
Chill in the fridge for at least 2 hours, or overnight for best results.
Red Chocolate Hearts
While the fudge sets, prepare the chocolate hearts. Heat a candy melting pot on high and add the red chocolate melts.
Stir often with a silicone spatula until fully melted and smooth.
Place a heart-shaped silicone mold on a small tray.
Fill the mold with melted chocolate, scraping off any extra with a cake spatula. Freeze for 5 minutes, then repeat the process 5 times until you have 5 filled molds.
Remove from the freezer.
Gently pop the chocolate hearts out of the mold.
Cutting the Fudge
Once the fudge is firm, take it out of the fridge.
Peel off the parchment paper, set the fudge on a cutting board, and put on disposable gloves to avoid fingerprints.
Use a 5-wheel pastry cutter to score straight, parallel lines across the fudge.
Rotate the fudge 90 degrees and score again to make a grid.
Cut along the scored lines, wiping your knife clean with a damp towel after each cut.
Push the pieces back together to help them keep their shape.
Turn the block 90 degrees and finish cutting along the lines.
You now have neat fudge squares!
For the final touch, dab a little melted chocolate on each square with a spatula.
Immediately place a red chocolate heart on top.
Repeat until every square has a heart—your Grinch fudge is ready to enjoy!
Notes
How to Store Fudge
At room temperature: Wrap the fudge in parchment or place it in an airtight container. Label the date and store for 2–3 weeks.
To freeze (uncut fudge): Place the whole block in a freezer-safe Ziploc bag, squeeze out extra air, and label the date. Freeze for up to 2–3 months. When ready, thaw the fudge in the fridge for 2 days before cutting and serving.
