How to Make Homemade Protein Powder

This recipe was originally published in 2014 – and has become our most popular recipe. I’ve updated the post with new photos and recent information (and side note: people often ask me what blender I use – here’s the $40 Black & Decker Blender I’ve used for decades now! [affiliate link].

So, over the years, dozens of friends have told me this homemade protein powder is a favorite for their kids and even for sick relatives. Here’s how it all began…

My sister wanted a grab-and-go breakfast for herself and her teenager; she thought a fruit smoothie with a scoop of protein powder would combine all the components of a balanced breakfast. But…she wanted a more affordable option than most store-bought varieties – and she doesn’t care for the artificial sweeteners in lots of the powders.

Here’s the recipe she texted me for my dietitian approval: “dry oats + brown rice + raw lentils: grind to powder”

Yikes. I texted back “breakfast #bellyache” as raw lentils are indigestible. In fact one of the reasons you cook them is to destroy some of the anti-nutritional factors that makes them inedible when raw.

So, instead, here’s the wholesome recipe I came up with using an under-utilized, convenient and super-nutritious item in the supermarket: instant nonfat dry milk – it’s actually just milk with the water removed – thus powdered milk. So, just like a glass of liquid milk, it contains whey. And according to a growing group of researchers, high-quality protein like dairy (whey) and eggs yield the best results in terms of muscle growth, muscle recovery, and may be beneficial for weight loss.

Each 1/2 cup-scoop of my Homemade Protein Powder has 180 calories and 12 grams of protein. To make it I combined:

  • Dry milk powder: A 1/3 cup serving has just 80 calories, a whopping 8 grams of protein, including whey protein, AND 8 essential nutrients.
  • Dry oats: A natural thickener because oats ‘plump’ in liquid. All oats are a healthy whole grain with significant amounts of fiber. Plus some researchers have show oatmeal has a special type of fiber that helps you feel fuller longer.
  • Almonds: Contains fiber and heart-healthy fats.

Homemade Protein Powder

Here’s the dietitian’s recipe for simple homemade protein powder – using a surprise budget-friendly ingredient.

  • Author: Serena Ball
  • Yield: 10 servings 1x


  • 3 cups (240 gm) instant nonfat dry milk, divided
  • 1 cup (80 gm) old fashioned or instant dry oats
  • 1 cup (142 gm) almonds
  • Sweetener of your choice


  1. Place 1 cup instant dry milk, 1 cup oats, 1 cup almonds in blender. Pulse until smooth.
  2. Place remaining instant dry milk in blender and pulse just a few times until blended.
  3. Place in container and cover tightly. Keep at a cool room temperature if you use within 2 weeks – if storing longer store in the refrigerator so the nuts don’t go rancid.
  4. To use, scoop 1/2 cup into 1/2-1 cup liquid in a blender; if possible let set 5-10 minutes for oats to plump. Add additional fruits, flavorings, yogurt or milks of your choice. Vanilla or almond extract is especially delicious.

IF I was to take this after a workout would I use a 1/2 cup of powder

Yes, 1/2 cup powder is one serving. To increase the protein content, add the 1/2-cup powder to milk or Greek yogurt. Thanks for visiting Elijah!

Calories are wrong

1 cup almonds 826 calories 3 cups dry milk 720 1 cup oatmeal 300 totals 1846 calories divided by 10 servings equals 184,6 calories

Hello. I was just wondering what brand and where everyone gets there nonfat dry milk from. Having some trouble finding it. Thanks. Very excited to try this!

I have found nonfat dry milk in regular supermarkets (not a specialty store) in the United States in the baking aisle. If you don't live in the US, I have heard that you can find higher fat dry milk powder, but I'm not sure where to find it - if not the baking aisle, maybe the baby aisle?

Hi, would you recommend this recipe for chemo patients?

We're not oncology dietitians. But yes, as long as the patient has no allergy to milk or nuts, this would be an inexpensive protein powder.

What can be used instead of almonds? I'd like to make this & send it to school with my son. Our schools are nut free. I receive financial assistance & really don't want to keep paying the high prices at the stores.

That's a great idea to make this at home and send to school with your son, Lisa. Ground flax seed actually has a protein content very similar to ground almonds. So you could substitute ground flax seed for the almonds and achieve nearly the same nutritional value.
