Protein Coffee Shake Recipe
Blend a creamy Protein Coffee Shake Recipe for a quick, caffeinated high-protein breakfast or snack.
Ingredients
- 1 cup (240 ml) strong brewed coffee, completely cooled and chilled in the refrigerator
- 1/2 cup (120 ml) unsweetened almond milk, cold (or dairy milk of choice)
- 1 medium ripe banana, sliced and frozen (about 100 g)
- 1 scoop (30 g) chocolate or vanilla whey protein powder (or plant-based protein powder)
- 1 tablespoon (15 g) natural peanut butter or almond butter, at room temperature
- 1–2 teaspoons (5–10 ml) pure maple syrup or liquid honey, optional, to taste
- 1/4 teaspoon pure vanilla extract
- 1/8 teaspoon fine sea salt (a small pinch, to enhance flavor)
- 1/2 cup (70 g) ice cubes (about 5–6 standard ice cubes), more for a thicker shake
- 1 tablespoon (10 g) rolled oats, optional, for extra thickness and fiber
- 1 tablespoon (8 g) ground flaxseed or chia seeds, optional, for added healthy fats
- 2 tablespoons (30 ml) plain Greek yogurt, cold, optional, for extra creaminess and protein
- 2–3 tablespoons (10–15 g) whipped cream, cold, optional garnish
- 1 teaspoon (3 g) unsweetened cocoa powder, optional garnish
- 1/4 teaspoon ground cinnamon, optional garnish
- 3–4 coffee beans or a few chocolate shavings, optional garnish
Instructions
Step 1: Brew and chill the coffee; freeze the banana
Brew a very strong cup of coffee and let it cool completely at room temperature, then transfer it to the refrigerator until well chilled — the shake relies on cold coffee so the ice and frozen banana don’t melt and thin the texture. While the coffee cools, peel and slice the ripe banana into 1/2‑inch rounds, arrange the slices in a single layer on a small tray or plate, and freeze until rock‑firm. This pairing of chilled coffee and fully frozen banana is the foundation for the thick, creamy mouthfeel of the finished shake.
Step 2: Layer the liquids and frozen fruit in the blender
Set a clean, dry clear blender jar on the marble surface. Pour the chilled brewed coffee into the jar, then add the cold almond milk so the liquids form a dark coffee‑and‑pale‑milk base. Add the frozen banana rounds, spreading them evenly over the liquids so they blend smoothly without clumping. Sprinkle one scoop of protein powder over the top so it sits dry and separate before blending, reducing the chance of lumps.
Step 3: Add the flavor boosters and optional body builders
Spoon in the natural peanut (or almond) butter, add a teaspoon or two of maple syrup if you want sweetness, then measure and add the vanilla extract and a small pinch of fine sea salt to quietly lift the flavors. If you want extra thickness or nutrition, add the rolled oats, ground flaxseed or chia seeds, and the cold Greek yogurt now — these ingredients change the density and creaminess dramatically, so they belong before the ice. Everything should sit layered in the jar: powders, nut butter dollop, and small dry add‑ins.
Step 4: Ice and secure the lid, then blend to silky smoothness
Top the jar with the measured ice cubes (start with 1/2 cup for a creamy but slightly frosty texture), secure the lid, and pulse on low to break up the ice and frozen banana, then increase to high speed until the mixture is uniformly smooth and thick with no visible chunks. If the blender struggles, stop, scrape down the sides with a spatula, then finish blending so the texture is homogenous and glossy — think velvety, opaque mocha. Taste and adjust: a splash more almond milk loosens it, another teaspoon of maple syrup sweetens it, and extra ice chills and thickens.
Step 5: Pour, garnish, and serve immediately
Pour the finished protein coffee shake into a chilled tall glass, leaving a little room for garnishes. Top with cold whipped cream if using, dust lightly with unsweetened cocoa powder and a whisper of ground cinnamon, and finish with 3–4 coffee beans or a few chocolate shavings for a neat, simple crown. Serve right away with a wide straw or spoon so the thick texture is easy to enjoy — the ideal experience is well‑chilled and luxuriously creamy.
Notes
- Use very cold brewed coffee and fully frozen banana slices to keep the shake thick.
- If your blender struggles, pulse and scrape the sides, then finish on high.
- Swap protein types and milk to suit dietary needs or flavor preferences.
- For a lower sugar version, omit maple syrup and use a less ripe banana.
- To batch make, blend and keep chilled in individual jars, then reblend briefly before serving.
