Chocolate Protein Shake

Before you start

Chalkiness in a protein shake comes from two things: powder that has not fully hydrated, and a drink that relies on the powder alone for flavor and body. The fix is to give the shake real structure from frozen banana and milk, add unsweetened cocoa so the chocolate tastes like chocolate, and let the powder blend into liquid before the ice and fruit go in.

Powders vary a lot. Whey usually dissolves cleanly, casein thickens, and plant blends based on pea or rice can taste earthy and gritty. This recipe works with any of them at one standard scoop of roughly 30 g, but plant powders benefit from a 2-minute rest after the first blend and a little more liquid. Follow your powder's label for the scoop size.

Ingredients

• 240 ml (1 cup) milk — dairy, soy or oat
• 1 scoop (about 30 g) chocolate or vanilla protein powder
• 1 tbsp (about 6 g) unsweetened cocoa powder
• 1 small frozen banana — in chunks
• 1 tbsp (16 g) peanut butter or almond butter — optional
• Pinch fine salt
• 4-5 ice cubes

Method

1. Pour the milk into the blender jar, then add the protein powder, cocoa and salt on top of the liquid, not underneath it, so no dry pocket sticks to the base.
2. Blend on low for 15 seconds, just until the powder disappears. Let the mixture rest for 2 minutes; the proteins absorb liquid and lose their sandy feel.
3. Add the frozen banana, nut butter and ice cubes.
4. Blend on high for 30 to 40 seconds, until thick and completely smooth. Stop once the vortex looks glossy; long blending whips in air and makes the shake foamy.
5. Taste and adjust. A teaspoon of maple syrup helps if your powder is unsweetened, and a splash more milk thins a very thick shake.
6. Pour into a glass and drink within a few minutes, before the foam separates from the body.

Tips for success

• Cocoa does more for flavor than extra chocolate powder. It adds bitterness and depth that the sweeteners in most powders lack.
• Salt matters. A small pinch rounds the cocoa and quiets the artificial edge some sweeteners have.
• If foam is a problem, let the shake stand for 1 minute and stir gently before drinking, or use a casein-heavy powder, which foams less.

Substitutions

Frozen banana

Use 75 g frozen cauliflower rice plus 1 tsp extra sweetener for a lower-sugar shake that is still thick; the taste is hidden by the cocoa.

Milk

Water works but makes a thin, more obviously powdery shake. Soy milk adds the most body among plant milks.

Peanut butter

Swap for 1 tbsp powdered peanut butter for less fat, or skip it; the shake will be slightly thinner.

Variations

Mocha protein shake

Replace 60 ml of the milk with chilled strong coffee. This adds caffeine.

Chocolate cherry

Swap the banana for 100 g frozen dark sweet cherries.

Troubleshooting

Clumps of dry powder

The powder went in first or the blend was too fast at the start. Add liquid first and start on low speed.

Shake tastes chalky

The powder did not hydrate. Use the 2-minute rest, add more liquid, and lean on banana and cocoa for flavor.

Thick foam on top

Blending too long incorporates air, especially with whey. Shorten the high-speed run and let the glass stand briefly.

Storage

Drink fresh. A dairy-based shake should go in the fridge right away if you are not drinking it, and be used within 24 hours. Do not leave it at room temperature for more than 2 hours.

Safety notes

Protein powders and nut butters are common allergen sources (milk, soy, peanut, tree nuts). Check the label on your powder if anyone you serve has a food allergy.
