Ingredients Notes
Rolled oats are the carb base—27g carbs, 5g protein per ½ cup, perfect for energy. Peanut butter adds fats and protein—natural, unsweetened (7g protein, 16g fat per 2 tbsp) for bulking. Protein powder boosts protein—vanilla whey or plant-based, 20-30g per scoop. Almond milk keeps it creamy—unsweetened for clean eating. Banana offers natural sweetness and carbs—ripe, 27g carbs each. Cinnamon warms it up—small but flavorful. Honey (optional) sweetens—natural and gym-friendly.
Variations and Substitutions
Swap rolled oats for steel-cut oats—more chew, longer cook time (30 minutes). Use almond butter or cashew butter instead of peanut butter—similar fats, slight flavor shift. Sub protein powder with Greek yogurt—10g protein per ½ cup, creamy texture. Replace almond milk with regular milk or oat milk—adjust calories as needed. Use berries or apple instead of banana—fewer carbs, different taste. Swap honey with maple syrup or skip for less sugar—tweak to macros. Add chia seeds or flaxseeds for extra fiber and fats—stir in early.
Storage Options
Store leftovers in airtight containers in the refrigerator for up to 4 days—ideal for gym meal prep! Reheat in the microwave with a splash of milk for 1-2 minutes to revive creaminess, or eat cold if you’re in a rush. Freezes well for up to 1 month; portion into freezer-safe containers—thaw overnight in the fridge and reheat for a quick breakfast.
