Pick your base. Add 1 to 1 1/4 cups of your favorite milk to the blender. Dairy gives extra creaminess, while soy or pea milk adds more protein. Oat milk is naturally sweet and silky.

Add the protein powder. Use one scoop (usually about 25–30 grams). If your powder is unsweetened, plan to add a touch of sweetener later.

Toss in the fruit. Add 1 small frozen banana or half a large one. This creates that thick, milkshake-like texture without needing a ton of ice.

Boost creaminess. Spoon in 1/4 to 1/2 cup of Greek yogurt or dairy-free yogurt. This amps up protein and gives a silky finish.

Layer on flavor. Add 1/2 teaspoon vanilla extract and a pinch of cinnamon if you like a warm, bakery-style note.

Adjust sweetness. Blend briefly, taste, then add 1–2 teaspoons honey or maple syrup if needed. If your banana is very ripe or your protein powder is sweetened, you may not need extra sweetener.

Customize the nutrition. For fiber and healthy fats, add 1 teaspoon chia or ground flax. For a more filling smoothie, add 1–2 tablespoons oats or a spoon of nut butter.

Blend until smooth. Start low, then move to high for 30–45 seconds. If it’s too thick, add a splash more milk. If you want it frosty, blend in a few ice cubes at the end.

Serve right away. Pour into a chilled glass or shaker bottle. For a bowl-style version, use less milk and top with granola and sliced fruit.
