In a small food processor, process oats and 1⁄4 cup raw pecans until it becomes fine like flour.
Next, add pumpkin puree, peanut butter, maple syrup, and pumpkin pie spice. Process until the mixture becomes like cookie dough.
Using a tablespoon cookie scoop, scoop dough into little balls.
Next, melt dark chocolate chips. Transfer melted chocolate into a small plastic bag and cut the tip off with a scissors. On each ball, squeeze a dot of chocolate. Place a raw pecan on top and drizzle with additional melted chocolate.
Place pecan pumpkin pie bites into freezer for about 15 minutes. Store in an airtight container or in the refrigerator.
