Set your oven to 350°F (175°C) and grease a 8x8 inch baking dish with coconut oil or cooking spray. Then add half of your gluten-free rolled oats to a high speed blender and process into a fine flour.
In a large bowl, combine oats, oat flour, baking powder, vanilla protein powder, salt, cinnamon, ground ginger and nutmeg.
In a separate bowl, add in the almond milk, eggs, melted coconut oil, maple syrup, and vanilla extract. Pour into the dry ingredients and stir until combined. Then fold in the shredded carrots, raisins and walnuts.
Pour the mixture into your prepared baking dish and bake for 30-35 minutes, or until set and golden brown. Let cool slightly.
Mix Greek yogurt, cream cheese, maple syrup, and vanilla extract in a bowl until smooth.
Spread the maple cream cheese glaze frosting over the warm baked oatmeal, slice, and enjoy your cake-for-breakfast moment. Can top with more shredded carrots, walnuts and raisins if desired.
