Line a 4x8-inch loaf pan with parchment paper, leaving extra to hang over the sides.
In a microwave-safe bowl, melt white chocolate chips in 30-second intervals, stirring often until smooth.
Add pumpkin puree and stir until mixture is smooth and uniform throughout.
Pour mixture into your prepared loaf pan. Cover with plastic wrap and place in the freezer until the fudge feels firm (usually 30–60 minutes).
Remove fudge from pan and place it on a cutting board. Using a large knife, cut the fudge into 1-inch pieces.
Place a candy pumpkin on top of each piece and freeze.
Notes
Use Room Temperature Pumpkin Puree: Make sure that your pumpkin puree is at room temperature before mixing. Cold pumpkin can cause your white chocolate chips to seize and harden.
Use High Quality Chocolate: Use high quality, fresh chocolate chips for the best melting and rich taste.
Measure Carefully: To ensure that your fudge firms up correctly and isn’t grainy, be sure to measure carefully so that you have the right chocolate-to-pumpkin ratio.
Serve Immediately After Freezing: This fudge tastes best straight from the freezer. If it’s left at room temperature too long, it can soften or start to melt, but should still taste delicious.
Freeze Leftovers: Store any leftover fudge in the freezer to enjoy all season long! It keeps well and stays creamy if stored properly.
