Preheat your oven to 400 F.
Grate your zucchini using a hand grater or box grater. Place it in a thin dish rag and squeeze out as much liquid as you can.
Transfer it to a bowl with the corn, scallions, onion, cheese, eggs and spices and mix well.
Add in the baking powder and oat flour and combine together until evenly mixed.
Line 1 large or 2 medium baking sheets with parchment paper. Scoop 1/4 cup of the mixture onto the tray and lightly flatten the top. You can also make these smaller by scooping only 2 tbsp worth of the mixture.
Once the trays are filled, drizzle each fritter with olive oil.
Bake for 15 minutes on the middle oven rack, then gently flip each one and bake for an additional 7 minutes.
While they bake, prepare your chipotle cream by blending all of the ingredients together in a blender. Adjust salt to your liking.
Serve fresh with the chipotle cream. Store leftovers in the fridge for up to 5 days.
