Best Protein Shake Recipes for Weight Gain

When it comes to building muscle and gaining weight, intense workouts are only part of the equation. Nutrition is key to optimizing muscle growth, and protein — often referred to as the building block of muscle — is essential to this process. (1) The final, and most important aspect, is overall energy intake. (2) Without an excess of calories, you can’t make the most of your training or protein intake. The best protein shakes can be an easy, delicious way to meet your calorie and protein goals. 

While there are plenty of weight gainer shakes on the market, they’re usually just blends of protein powder and maltodextrin, a simple carbohydrate. They don’t offer much when it comes to vitamins, minerals, or variety. If you’re looking for a more nutritious, budget-friendly option, you can easily create delicious, energy-dense protein shakes with whole foods and protein powders that fit a variety of different dietary patterns. Here are the best protein shake recipes for weight gain out there.

1. Chocolate Peanut Butter Banana Milkshake

If you’re a fan of peanut butter cups, you’re sure to like this recipe. This shake provides about 500 calories and roughly 25 grams of high-quality protein from low-lactose options like the best whey isolates to stimulate muscle protein synthesis.(3) 

Compared to regular whey protein, isolate is generally more tolerable to folks with lactose intolerance. Plus, with a creamy, milkshake-like texture from the frozen banana, you might want to have it for dessert!

Nutrients 

• Calories: 500
• Protein: 35 grams

• 1 tablespoon honey
• 1 frozen banana

Instructions 

Start by pouring the milk into your blender, then add the honey. Add the frozen banana in small chunks. Add remaining ingredients. Blend ingredients together until smooth. 

2. Vegan Tropical Paradise Shake

Vegan diets can be just as effective as omnivorous diets for supporting muscle growth and weight gain. (4) As registered dietitian Austin Bou points out, “It was once believed that plant-based diets are inadequate for muscle growth. In fact, recent research has shown that vegan diets can produce equal results when compared to an omnivorous diet; however, it’s important to focus on the amount of protein consumed.” This is definitely a shake that can help you hit that mark.

Whether you’re vegan or simply wanting to include more high-protein vegetables and fruits in your diet, this fruity, refreshing shake provides about 450 calories and 30 grams of protein from pea protein powder and almond butter. 

Nutrients 

• Calories: 450

3. Greek Yogurt Parfait Shake

If you like to snack on Greek yogurt with berries or granola, you’re in luck. You can make it even more delicious and portable by turning it into a protein shake! This recipe provides about 30 grams of protein from casein and Greek yogurt, which can help stimulate muscle protein synthesis with their high leucine content (characteristic of animal-based protein sources.) (3) 

It’s also sweetened with honey, which is an energy-dense carb source that contributes to its high calorie content — about 500 calories. 

Nutrients

4. Vanilla Cinnamon Oat Shake

Love your morning oatmeal, and want to take it on the go? You can add it to your next protein shake. This blend of egg white protein, oats, fruit, and maple syrup might sound like breakfast in a blender, but trust me, this type of protein powder doesn’t taste like scrambled eggs! 

Think: overnight oats, but smooth. The combination of energy-dense ingredients and high-quality protein powder will add about 35 grams of protein and nearly 600 calories. (Egg white powder not your vibe? You can swap in any of the best tasting protein powders!)

5. Vegan Banana Cashew Cream Shake

Soy protein is another great plant-based alternative to dairy-based protein powders, and it’s the base for this delicious recipe. (3) The blend of creamy cashew milk, cashew butter, and frozen banana make it seem like more of a milkshake than a protein shake. It’s an easy way to add another 30 grams of protein and roughly 400 calories to your daily intake. 

Nutrients 

• Calories: 400

Best Protein Shake for Weight Gain Ingredients

Now that you’ve tried some game-changing protein shake recipes, you might want to build your own. Here are the key ingredients to get you started!

Ingredient 1 — Protein Powder

The best protein powders can be equally beneficial when combined with adequate energy intake and training, so choose the one that will best suit your dietary pattern and digestion.(3)(4)(5) (The exception: collagen protein and collagen peptides don’t contain the proper combination of amino acids to support muscle protein synthesis, so this wouldn’t be a useful ingredient for muscle growth alone.) (6)(7) 

Animal-based protein powders like whey protein, casein, and egg white are all high-quality protein sources due to their blend of amino acids and high leucine content. Plant-based protein powders like soy or pea protein are generally formulated to provide the right amount of amino acids to support muscle growth. (3)(4)(5) 

Ingredient 2 — Milk or Milk Alternative

While you can make a protein shake with water, you can add more calories — plus deliciousness and texture — to your protein shake by using milk or a milk alternative. Whole milk is more energy-dense than reduced fat versions due to its higher fat content, while oat, hemp, and soy milk tend to be the more caloric plant-based milk alternatives.(8) 

These milks can also add a different texture to your shake, which could make it more appetizing in some cases but too filling in others. If you’re adding a thick ingredient like yogurt or oatmeal, you might want to use a milk alternative with a higher water content, like almond milk, so your shake isn’t so thick that you feel full halfway through.

Ingredient 3 — Nut Butter

Nut butter is high in fat, making it extremely energy-dense. This ingredient adds a significant number of calories without adding too much volume to your protein shake. Nut butters tend to have very similar nutrient profiles, but their tastes vary. Cashew butter tends to be sweeter, while almond butter has a milder, earthy taste. 

Whatever type you choose, be sure to pick a brand that’s free from hydrogenated oils. These are used to maintain the texture and shelf life of many nut butters, but they contain trans fats which are linked to heart disease and should be avoided. (9)  

Ingredient 4 — Frozen Fruit

Protein powder, milk, and nut butter can make a great shake on their own, but frozen fruit takes your shake to another level. Fruit makes your shake sweeter and more nutritious by adding fiber and micronutrients, like vitamin C and potassium. Frozen fruit – especially bananas – turn your protein shake into a protein smoothie. Bananas are one of the most energy-dense options, but plenty of other fruits like berries, pineapple, mango, and peaches also freeze well.

Optional Additions

If you want to make your shake or smoothie even more energy dense, you can sweeten your shake with honey or maple syrup, sprinkle in some chia seeds, or even add blended oats. These can all add more calories to your shake without increasing the amount you have to drink. 

Honey and maple syrup are energy dense, packing plenty of carbohydrates in small amounts. Like nut butters, chia seeds add healthy fats and extra calories to your shake without taking up much extra space. Oats will add more carbohydrates and make your shake thicker, so they might pair better with a thinner milk base, like almond milk. 

If you’ve tried all of the above and you still aren’t seeing the gains you’d expect, you could swap your protein powder base for a weight gain shake to add even more calories to the mix. 

Tips From a Health Coach on How to Make Protein Shake Recipes for Weight Gain

Of course, this isn’t an exhaustive list of ingredients or combinations. If you’re a protein shake pro and you’re ready to get creative, follow these general guidelines. 

Choose High-Calorie Ingredients

Protein powders are, obviously, high in protein; they’re also relatively low in calories because they contain hardly any fat or carbohydrates. So, if you want to make your protein shake more effective for weight gain, you need to add other sources of calories from energy-dense foods. 

Energy-dense foods are high in calories per gram; in other words, they pack plenty of calories into a small serving. Some examples include oils, nuts, and nut butters, which are all naturally high in healthy fats. Other foods, like dried fruit, can be made more energy-dense through processing. The carbohydrates become more concentrated once the water is removed. Milk and yogurt are sold with different fat content, like 1% or whole milk. 

When you’re putting your grocery list together, opt for the ingredients with more calories per serving, like whole milk instead of fat-free milk and real peanut butter instead of low-calorie powdered versions.
