Some mornings you want oatmeal, and some mornings you want to drink breakfast on the way out the door. This peanut butter oat smoothie gives you both. Rolled oats, frozen banana, peanut butter, soy milk, and silken tofu blend into a thick, cookie-dough-flavored shake that tastes like a treat and eats like a meal.
One smoothie gives you 26 g protein, 8 g fiber, and about 482 calories, with no protein powder. It takes about 5 minutes.
Because it is a full breakfast, it runs a bit higher in calories than a lighter fruit smoothie. To see how it fits your day, try my free macro calculator.

Why This Recipe Keeps You Full
Rolled oats are what set this smoothie apart. They add slow-digesting carbohydrates and a type of soluble fiber that thickens the drink and helps it feel substantial. The result is closer to a bowl of oatmeal than a glass of juice.

Peanut butter brings protein and healthy fats, plus that rich, nutty flavor. Fat and fiber together are a strong pair for staying full, so this is a good pick for long mornings.
Soy milk and silken tofu build the protein base. Silken tofu also makes the texture thick and creamy, almost like a milkshake, without any ice cream.
A frozen banana ties it all together with natural sweetness and a frosty chill. Add a pinch of cinnamon and you have something that tastes like an oatmeal cookie in a glass.
It is also easy to scale to your needs. On a rest day, a smaller glass may be plenty; after a long run or a strength session, the full smoothie with a piece of fruit makes a satisfying recovery meal. Adjust the portion rather than skipping breakfast altogether.
A Few Notes on the Ingredients
Rolled oats. Old-fashioned rolled oats blend best. If your blender is not very powerful, soak the oats in the soy milk for 5 to 10 minutes first, or overnight in the fridge.
Peanut butter. Choose natural peanut butter with just peanuts and salt. Stir it well so you get an even mix of oil and solids.
Silken tofu. It blends completely smooth and adds protein without any flavor of its own. Keep a shelf-stable carton in the pantry for easy smoothies.
Cinnamon. A small pinch adds warmth and makes the smoothie taste sweeter without extra sugar.

- Gluten-free: Use certified gluten-free rolled oats. Regular oats are often processed alongside wheat.
- Nut-free: Swap the peanut butter for sunflower seed butter. It tastes great with banana and oats.
- Protein boost: Add 10 g hemp hearts (1 tbsp) or 0.25 cup plain soy yogurt.
- Chocolate version: Blend in 1 tbsp unsweetened cocoa powder for a chocolate peanut butter shake.
- Lighter version: Use 1 tbsp peanut butter and half a banana for a smaller morning drink.
Storage, Leftovers, and Serving
This smoothie thickens as it sits because the oats keep absorbing liquid. If you make it ahead, refrigerate it in a sealed jar for up to 24 hours and stir in a splash of soy milk before drinking.
For overnight prep, combine the oats and soy milk in the blender jar and refrigerate. In the morning, add the rest and blend.
Pack it in an insulated bottle for a filling breakfast on the go, or sip it after a strength workout.
Pair it with a piece of fruit for a complete breakfast. For more filling blends without protein powder, browse my smoothie recipes.
