Why you should make this recipe

The peanut butter bites are absolutely perfect when you find yourself craving a little taste of something sweet. Plus, they have a nice 7.6 grams of protein per serving!

Ingredients

This simple recipe has only four ingredients, commonly found in a keto pantry, plus sweetener and peanuts for a delicious crunch.

• peanut butter: look for natural peanut butter with no added sugar, salt, or preservatives; use creamy peanut butter for the best flavor and texture, and ensure that the ingredients are only peanuts
• protein powder: my favorite is vanilla protein powder like Met-RX Vanilla Protein, but any good brand will do as long as you like the taste; the vanilla in the protein powder adds sweetness and flavor to the protein balls, so it’s an important part of the recipe.
• vanilla extract
• cinnamon
• stevia: use Stevia in the raw for the best texture
• peanuts: look for raw, unsalted peanuts; adds excellent crunch on top of the protein balls

Step-by-step instructions

Whipping up a batch of these no-bake energy bites is so easy. If you have a blender, it can be done in 10 minutes. If you don’t have a blender, it may take you 12 minutes total time.

You’re only 5 easy steps away from these super tasty peanut butter protein bites!

You can see how I do it in this short video, or follow the step-by-step instructions below:

Note: I have slightly reduced the amount of protein powder I use since I made this video. Please use the amount listed in the recipe description below.

Step 1: In a mixing bowl, mix the peanut butter, protein powder, vanilla extract, cinnamon, and stevia until smooth. 

Step 2: Break off approximately 2 tablespoons of the dough and roll between your palms into 1 or 1½-inch balls. Place the balls on a baking sheet lined with parchment paper. You should end up with approximately 15 balls.

Step 3: Next, place the raw peanuts in a blender (I use my NutriBullet) and pulse several times until it’s coarsely chopped. If you don’t have a blender, you can chop them instead on a cutting board with a sharp knife.

Step 4: Roll the balls in the peanut crumbles, then transfer them back to the sheet. Alternatively, you can just sprinkle some peanut crumbles on top of the peanut butter balls.

Step 5: Place in the refrigerator and let set for at least 20-30 minutes.

Expert tips

I have a few tips and tricks to make sure peanut butter energy balls are as easy as possible!

• Mix peanut butter well before using it. Natural peanut butter separates, so the jar will often have more oil on top and more solids at the bottom. This can make the protein balls either too runny or too dry if you don’t mix it all up! To avoid drippy peanut butter, mix it well first directly in the jar.
• Combine dry ingredients first. To make the mixing easier, it may be best to combine the dry ingredients first like protein powder, sweetener, and cinnamon. 
• Pop the dough in the freezer. If the dough mixture is too sticky to handle, pop it in the freezer for 10 minutes. It will be much easier to roll! This is especially helpful in hot and humid climates. 
• Don’t overdo the peanuts. When pulsing the raw peanuts in the blender or food processor, don’t overdo it! You want small crumbles, not peanut flour. Naturally, you have more control over this with the traditional cutting board and knife method.

Variations

The low-carb protein balls are great, as written in the recipe card with the ingredients mentioned above. But you can change things up to give different flavor profiles.

Check out these suggestions to add variety to your energy balls:

• Use a different nut butter like almond butter or cashew butter.
• Substitute vanilla protein powder with chocolate protein powder for chocolate peanut butter balls.
• Use sweetener of choice: other low-carb options like monk fruit will work, but if you want a traditional unprocessed sweetener, just a touch of maple syrup will be tasty.
• Top with chopped chocolate or mini chocolate chips.
• Additional toppings to add to homemade protein balls include cacao nibs, coconut flakes, hemp hearts, and chia seeds. 

Serving suggestions

A serving size of one peanut butter energy ball is packed with enough protein, fats, and fiber to hold you well until mealtime. Pull one directly from the refrigerator or freezer and pop it in your mouth for a guilt-free, truffle-like experience. 

Storage instructions

You can store the peanut butter protein bites in an airtight container in the refrigerator for 3-4 days. For more extended storage, keep them in the freezer in a sealed container for up to 6 weeks. 

They are so nice to have on hand when you want something tasty so feel free to double or triple the recipe!

Nutrition

These delicious morsels are naturally gluten-free and dairy-free and make a fantastic satisfying snack. Even though they are not low in calories, they are still a stellar source of protein, healthy fats, and fiber from the peanut butter.

To keep this protein ball recipe healthy, ensure that your peanut butter and protein powder are of good quality. Make sure your peanut butter has no added salt or sugar. And if you use other protein powders, always read the ingredient list to check for unnecessary additives and sugar.

Furthermore, these are great snacks for people with diabetes as they are low in carbs and provide fuel for energy from peanut butter and protein powder.
