Preheat the oven to 350°F. Prepare a baking tray with baking paper and set it aside.
Mix the chia seeds with water and let them sit for 10–15 minutes until the chia egg has developed.
Make homemade oat flour: Process rolled oats in a high-speed blender until oats are ground. To make two cups of homemade oat flour, you’ll need 2 ⅓–½ cups of rolled oats. However, you can also use store-bought oat flour if desired.
Mix wet ingredients—pumpkin puree, non-dairy milk, vanilla extract, maple syrup, and chia egg—in a large bowl until well combined.
Add raisins, cinnamon, pumpkin spice, and baking powder and combine.
Finally, add oat flour and stir to combine.
Cover the batter with wrapping paper or a silicone wrap and place it in the fridge for 20–30 minutes to allow the oats to absorb any excess liquid.
Roll the batter into 20 balls and then coat each of them with rolled oats.
Bake the balls for 10–12 minutes or until oats get lightly brown.
Store these energy balls in an airtight container in the fridge for up to five days.
These energy balls aren’t super sweet; they are meant as a healthy snack. Adjust their sweetness by adding one or two more tbsp of maple syrup or extra raisins.
