In a microwave safe bowl, microwave the white chocolate chips and coconut oil on half power in 30 second increments, stirring after every 30 seconds. It took me about 4 minutes total. If you prefer the stovetop, use a double broiler as white chocolate is easy to burn. It's much easier to do in the microwave!
12 ounces (340 grams) white chocolate chips, 5 3/4 tablespoons (80 grams) refined coconut oil
Once completely melted, take out of the microwave and add the pumpkin puree, spices and the seeds of the vanilla bean, if using. At first the oil might separate and it might look curdled. Just keep stirring and stirring. It'll come together after about a minute.
1/3 cup (80 grams) canned pumpkin puree, 2 1/2 teaspoons pumpkin pie spice, seeds of 1 vanilla bean
Pour into a parchment or wax paper lined 9"x5" loaf pan or use about 12-16 silicone mini muffin liners in a mini muffin pan. Place in the freezer or refrigerator to firm up. It took about 45 minutes in the freezer. Store in the fridge or freezer.
