Need more protein shakes for weight gain? Try my protein milkshake, coffee protein shake, chocolate protein shake, and protein coffee next. of course, there are healthier ways to be in a calorie surplus. That’s where my weight gainer shakes come in. With added calories and protein, one shake a day can easily help you gain weight and build muscle. Plus, they actually taste good!
Why I love this recipe
Healthy. There’s no refined sugar, and each one is full of vitamins, minerals, fiber, and protein to help you build and retain muscle. So many flavor options! The high calorie protein shake recipe is pretty simple, but I included tons of different flavorings so you never have to make them the same way twice. Convenient. Cooking your calories takes a while, so I prefer to make a shake. Plus, they work just as well for breakfast, a post-workout snack, or even dessert. Also, from personal experience, they are SO much easier to consume than whole foods. Indulgent. They’re thick, creamy, and taste exactly like a milkshake!
Ingredients needed
Protein powder. I typically use vanilla whey protein powder, but when I’m looking to add even more bulk, I opt for a high-calorie protein powder. These typically contain an extra 200-300 calories per serving. Opt for a clean brand like Optimum or Dymatize. Rolled oats. Also known as old fashioned oats. Quick oats can work, but the former will make for a thicker smoothie. Use certified gluten-free oats if needed. Peanut butter. For healthy fats and extra calories. Feel free to use other nut butters like almond butter. Maple syrup. For essential sweetness. Honey or agave nectar also works. Milk. I used unsweetened soy milk, but whole milk also works. Mix-ins. For the three main flavors, you can choose between cocoa powder, banana, or strawberries. See below for more flavor options.

In a high-speed blender, add all the ingredients and blend until smooth. If using mix-ins, add them and blend once more. Step 2- Serve. Pour into a large glass or a protein shaker bottle and enjoy.
Arman’s recipe tips
Make them vegan. Use plant-based protein powder (like pea protein) and dairy-free milk. Nut-free. Use sunflower seed butter or tahini. Swap the oats. Use other grains like buckwheat flakes, brown rice flakes, or any other flake cereal. Lower the carbs. Try making my keto shakes instead. Use Ensure protein drink instead of milk to add even more calories! I’ve tested this with vanilla and chocolate and it tastes delicious without leaving you feeling heavy or sluggish.
Storage instructions
To store: Weight gain smoothies should be enjoyed within 2 hours of preparation, but they can be stored in the refrigerator for up to two days. When ready to drink, be sure to add a splash more milk to thin it out. While you can resort to a weight gain protein powder (like a mass gainer), you can add whole foods to increase the calories. Here are some ideas:
Avocados. Heart-healthy fats and fiber. Per one medium avocado, there are approximately 245 calories. Full-fat yogurt. Adds extra protein and creaminess. Per one cup serving, there are 220 calories. Coconut flakes. Add coconut flakes to one of the chocolate-based smoothies. A 1/2 cup serving provides 150 calories. Ice cream. Turn your weight gain smoothie into a milkshake! One scoop quickly provides around 300 calories. Chia seeds. Adds fiber, protein, and healthy fats. Per 1/4 cup serving, there are 200 calories. Be sure to add an extra 1/2 cup of milk to the shake so it will blend smoothly.
Real talk here. If I had to have the same high calorie protein shake day in day out, I’d be bored out of my mind! So, I’m sharing the ten or so flavors I rotate between to keep things interesting.
Triple berries. Add ½ cup of fresh or frozen raspberries, blueberries, and strawberries. Cookies and cream. Add 1-2 Oreo cookies. Nutella. Instead of peanut butter, use healthy Nutella. Add 1-2 tablespoons of cocoa powder to enhance the chocolate flavor. Double chocolate. Use chocolate protein powder, add 2 tablespoons of cocoa powder, and drizzle with chocolate syrup. Chocolate peanut butter. Use peanut butter and add 2 tablespoons of cocoa powder. Banana. Add a frozen banana and use honey as the sweetener. Strawberries and cream, Add 1 cup of frozen strawberries and replace half the milk with Greek yogurt. Snickers. Add cocoa powder, caramel syrup, and cocoa powder. Chocolate coconut. Add 1/4 cup of unsweetened shredded coconut flakes and use coconut milk. Tropical. Add coconut chunks and pineapple chunks, and use coconut milk.
To prep: Prepare baggies of oats and protein powder. When ready to make a shake, simply throw it into a blender with the nut butter, maple syrup, milk, and any add-ins and blend until smooth.
