Most of us are short on time in the morning. We end up grabbing a quick cup of coffee and were out the door with no nutrition to start the day!

Made with protein powder to give you a high protein start to the day, with a bit of espresso powder to give you a kick of energy you need in the morning. This protein shake is like combining breakfast and your morning coffee in one!
I’ve also added some peanut butter powder to this shake because I love the taste of peanut butter. It makes this protein shake creamy and smooth without all the extra added calories from fat.
This simple breakfast drink is made by blending all the ingredients until smooth. It's the perfect drink made in no time!

Ingredients You’ll Need

- Unsweetened Almond Milk: This makes up the liquid base of this shake and is low in calories.
- Whey Protein Powder: You can use any protein powder you enjoy to bump up the protein in this shake.
- Banana: A banana adds healthy carbs and potassium to the drink and helps keep it smooth.
- Espresso Powder: Gives a burst of energy to this morning shake.
- Peanut Butter Powder: Adds peanut butter flavor without all the added fat and makes it creamy.
- Ice: You’ll need ice to give it a cold frozen texture when blending.
Step-By-Step Instructions

Step 1: Add the ice and almond milk to the blender.
I like adding the ice and almond milk first because the blender will start to break down the ice first making the blender easier to clean.
Step 2: Add the remaining ingredients.
On top of the ice and almond milk, add the protein powder, banana, espresso, and peanut butter powder.
Step 3: Blend until smooth.
Depending on how much power your blender has, pulse the ice until it's broken down. Then, blend until the shake is smooth and creamy.

Expert Tips
- If you’re using larger ice cubes, you can pulse them first with the almond milk to help the protein shake break down easier.
- Pour the protein shake in a stainless steel mug to keep it nice and cold for much longer.
- Freezing the banana beforehand helps keep the drink cold and makes a smooth consistency.
- If you don’t have peanut butter powder, you can use regular peanut butter, however, this will add more calories to the shake.
Variations
Any variations made to this shake will change the number of calories in the shake. Calculate the new ingredients for the proper calorie count.
- Change up the fruit: Add in your favorite berries or cherries, either frozen or fresh. Peaches and pineapple work well too!
- Protein powder flavors: I use vanilla or chocolate protein powder for this shake because it pairs well with the peanut butter and espresso. However, feel free to use whatever flavor you enjoy.
- Don’t need a buzz? You can completely omit the espresso in this recipe if you don’t want any caffeine.
- Those who are allergic to peanuts can use almond butter, cashew butter, or sunflower seed butter for a nut-free protein shake.
- Change up the milk: I use unsweetened almond milk in this recipe because it is low-calorie and creamy. However, feel free to use whole milk, cashew milk, hemp milk, oat milk, or whatever you prefer.
Storing & Freezing
Storing: This protein shake is best served immediately because the ice will melt quickly.
Freezing: If you have any leftover shake, try freezing them in popsicle molds or ice cube trays. They're great to be used or blended up at a later time!
Recipe FAQ's
Peanut butter powder is made from peanuts without much fat.
To make peanut butter powder, the peanuts are ground up and the oil is pressed out. The remaining material is dried out and ground into powder.
You can put peanut butter powder in smoothies, or you can mix it with a small amount of water or milk to create a thick peanut butter consistency without the excess fat.

I've heard about peanut butter shakes, but I've never actually tried one. This one sounds really interesting and good! I'm curious what espresso powder you use. Is it a powder like the peanut butter powder or is it more like instant coffee?

Hi Alison. The espresso powder is more like instant coffee. It adds a great flavor to the shake.
