Mix the pumpkin, almond butter, and honey together in a large mixing bowl until smooth.
Roughly chop the oats in a mini food processor. This step is optional but I find that the balls hold together better if they're chopped into smaller pieces.
Add the oats, protein powder, pumpkin pie spice, and salt to the bowl with the wet ingredients. Using a spatula, stir to combine all the ingredients well.
Form the mixture into balls, about 1-inch in size. You can do this with your hands or a small cookie scoop. Roll them around in your hands to compact them so that they stay together.
To make the white chocolate drizzle, put the white chocolate chips and coconut oil in a small bowl in the microwave. Heat in the microwave in 30 second increments until chocolate is melted. Stir until smooth.
Drizzle the melted white chocolate on top of the balls and sprinkle a little sea salt on top. Place the balls in the freezer until firm.
You can store the energy balls in an airtight container at room temperature for 2-3 days, in the refrigerator for up to 2 weeks or in the freezer for up to 3 months.
