For gluten-free, use certified gluten-free oats. Maple syrup can be swapped with honey or agave. To avoid clumps, mix protein powder with milk before adding other ingredients. Keep a close eye on pecans while candying to avoid burning. Stir oats well before refrigerating. Add extra milk in the morning if oats are too thick. Candied pecans can be replaced with toasted pumpkin seeds or sunflower seeds for nut-free option. Vegan version uses plant-based protein powder, non-dairy milk, and coconut yogurt instead of Greek yogurt.
