Cooking With Unflavoured Protein Powder: Simple Ratios for Oats, Smoothies, Soups and Baking

Flavoured protein powder is made for shakes. Unflavoured powder is made for everything else. Without sweetener or flavouring, it can go into savoury food, breakfast bowls and baking without changing the taste of the dish. The catch is texture. Add too much, add it at the wrong moment, or add it dry to hot liquid, and you get clumps, a gluey batter or a dry muffin.

This guide gives starting ratios using Inna Protein's Unflavoured Vegan Protein Powder as the example. Inna describes it as a single-ingredient product: Australian-grown faba bean isolate with nothing added, 25.3g of protein and 107 calories per serve, zero sugar and no sweetener. A 750g bag holds 25 serves, so one serve is 30g, or roughly two to three heaped tablespoons depending on your scoop.

The three rules that prevent most problems

1. Make a slurry first. Whisk the powder into a small amount of cool or room-temperature liquid before it goes anywhere hot. Dry powder dropped into hot liquid clumps.
2. Add late for hot dishes. Stir protein in at the end of cooking, off high heat, rather than boiling it.
3. Replace, don't just add, in baking. Protein powder absorbs liquid differently from flour. Swap a portion of the flour rather than piling powder on top of a full recipe.

Oats and porridge

Starting ratio: 1 serve (30g) of powder per 1 bowl of cooked oats, about 40 to 50g of dry oats.

Cook the oats as normal. Take them off the heat, let them sit for a minute, then stir in the powder mixed with two or three tablespoons of milk or water. Add a splash more liquid if the oats thicken too much. Overnight oats are even simpler: stir the powder into the liquid before adding the oats, then refrigerate.

Smoothies

Starting ratio: 1 serve per 250 to 350ml of liquid, plus fruit.

Put the liquid in the blender first, then the powder, then the fruit and ice. This order keeps powder from sticking to the base of the jug. Because the unflavoured powder has no sweetener, the sweetness comes entirely from the fruit, which is the point for anyone cutting back on sugar. Banana and frozen berries are reliable choices.

Yoghurt bowls

Starting ratio: half a serve (15g) per 150 to 200g of yoghurt.

Yoghurt thickens quickly when protein is stirred in. Start with half a serve, stir well, and loosen with a teaspoon or two of milk if needed. A full serve works in a larger bowl, but expect a thicker, mousse-like texture.

Soups and sauces

Starting ratio: 1 serve per 2 bowls of soup, or per 500ml of sauce.

This is where an unflavoured powder earns its place. Inna specifically suggests adding it to soups and sauces. Whisk the powder into a little cool stock or water to make a smooth slurry, then stir it into the soup at the end of cooking over low heat. Creamy soups such as pumpkin, potato or cauliflower hide it best. Avoid vigorous boiling after the protein goes in.

Baking: muffins, pancakes and protein balls

Starting ratio: replace about a quarter of the flour with protein powder.

For a recipe using 200g of flour, try 150g flour and 50g protein powder. Protein powders tend to absorb more liquid and can make baked goods drier and denser, so be ready to add an extra tablespoon or two of milk, mashed banana or yoghurt. Check muffins a few minutes early; protein-heavy batters can over-bake quickly.

For no-bake protein balls, a common starting point is 1 serve of powder per cup of oats and nut butter mixture, adding a little liquid until the mixture holds together.

If you would rather not experiment with pancakes, Inna also sells ready-to-mix vanilla and chocolate protein pancake mixes ($14.50 each, or $22 for a 2-pack). Inna lists 21.2g of protein per 100g for vanilla and 22.1g for chocolate, mixed with an egg (or a mashed banana for a vegan version), 1 1/3 cups of milk and 2 tablespoons of melted butter or oil.

A quick ratio table

• Oats: 30g powder per bowl, stirred in after cooking
• Smoothie: 30g per 250 to 350ml liquid
• Yoghurt: 15g per 150 to 200g yoghurt
• Soup: 30g per 2 bowls, added as a slurry at the end
• Sauce: 30g per 500ml, added as a slurry over low heat
• Baking: replace about 25% of the flour, add extra moisture

These are starting points, not fixed rules. Adjust to the texture you like.

When to choose a flavoured powder instead

If you mainly drink shakes, a flavoured powder is easier. Inna's Vanilla, Chocolate, Coconut, Salted Caramel and Matcha powders each provide 24.3g of protein and 114 calories per serve. Vanilla and chocolate also work well in sweet baking. Save the unflavoured version for savoury food and for recipes where you want full control of taste and sweetness.

Conclusion

Unflavoured protein powder works in almost any meal if you remember three things: slurry first, add late to hot food, and swap rather than add in baking. Start with the ratios above, adjust to taste, and you will rarely need a separate shake again.
