This coffee protein shake recipe is refreshing in the summer when hot coffee is too hot and I want an all-in-one breakfast smoothie packed with energy and filling ingredients.

Summer heat = iced coffee

I know there are die-hard iced coffee lovers who drink it year round, but for me, iced coffee is purely a summertime thing. When it’s warm enough in the morning that I start to sweat with my coffee, I switch to iced coffee for a short season.

Coffee for one

Back in the days before I was married to a coffee fanatic, I used to do the same “cook once, consume twice” pattern with my coffee that I do with our dinners. I’d make a bigger pot of coffee and have it hot one day and save the leftovers to have iced the next. I also had a cold brew coffee concentrate phase. That led to also freezing some of the coffee into cubes for recipes.

Fast forward to the present: I recently had one of the coffee flavored Daily Harvest smoothies, and they rekindled my craving for the coffee smoothies I would sometimes make with those cubes!

What exactly is a coffee protein shake?

It’s a brilliant fusion of the beloved java and a protein-packed smoothie that makes a great post-workout bev or all-in-one breakfast. I’m calling this a shake because it tastes so much like a coffee chocolate milkshake! But smoothie or shake – it’s blended goodness in a glass. And not only are you getting 20-30 grams of protein in this breakfast shake (depending on your protein powder of choice), you’re also getting healthy fats from the milk and nut butter and a dose of greens too.

What sets a coffee protein shake apart from your regular cup of joe?

Unlike traditional coffee drinks that often come loaded with sugar and cream, this smoothie blend combines the rich flavors of coffee with the power of protein, nut butter and greens, ensuring a balanced and nutritious start to your day. And it tastes like a coffee vanilla milkshake!

Ingredients

½ cup ice cubes made from brewed coffee

How To Make Coffee Protein Shake

1. Prepare the coffee ice cubes

Brew a cup of strong coffee and let it cool. Pour the cooled coffee into an ice cube tray and freeze until solid.

2. Gather all the ingredients

You will need ½ cup of coffee ice cubes, 2/3 cup of whole milk, ½ a frozen banana, 1 scoop of vanilla protein powder, 1 tablespoon of almond butter, and a handful of baby spinach.

3. Add the ingredients to a blender

Place the coffee ice cubes, whole milk, frozen banana, vanilla protein powder, almond butter, and baby spinach into a blender.

4. Blend until smooth

Secure the lid on the blender and blend the ingredients on high speed until the mixture is smooth and creamy. This should take about 1-2 minutes, depending on the power of your blender.

5. Adjust consistency if needed

If the shake is too thick, you can add a splash of additional milk and blend again until desired consistency is reached.

6. Pour and enjoy

Once the shake is smooth and creamy, pour it into a glass and savor the delicious flavors. You can garnish with a sprinkle of cinnamon or cocoa powder, if desired.
