Instructions to Make Protein Brownie Bites – Step by Step

Let’s walk through how to make these delicious Protein Brownie Bites step by step — no fancy equipment, no stress, and definitely no dry “healthy” snacks here. This is one of those recipes that feels almost too easy to be good, but trust me — it delivers every single time.

Step 1: Preheat and Prepare Your Baking Setup

Start this step by step process by preheating your oven to 350°F (175°C). A properly heated oven is key — it ensures your brownie bites bake evenly and develop that soft, fudgy center. While the oven warms up, grab a muffin tin and line it with eight silicone baking cups. If you haven’t tried silicone cups yet, you’re missing out — they’re nonstick, reusable, and make cleanup a breeze. You can read more about portion control baking tips in our post on Salted Caramel Protein Balls, where we also use silicone molds for perfect bite-sized treats.

If you don’t have silicone baking cups, you can lightly grease a regular muffin tin with coconut oil or nonstick spray. This simple preparation step keeps your brownie bites from sticking — because nothing ruins a good baking day faster than scraping chocolate off metal.

Step 2: Mash the Bananas (Your Natural Sweetener)

Now it’s time to bring those overripe bananas into play. Peel three bananas and place them in a medium-sized mixing bowl. Using a fork or potato masher, mash them until mostly smooth. It’s totally fine if there are a few small chunks — they’ll blend into the batter later. This step is where your Protein Brownie Bites step by step journey gets naturally sweet. Bananas don’t just add flavor; they also replace refined sugar and oil while keeping your brownies moist.

If you’re short on bananas or prefer a different flavor, you can substitute them with unsweetened applesauce. For more swap ideas, check out our Cookie Dough Protein Balls article, where we share smart ingredient alternatives for clean desserts.

Step 3: Add the Nut Butter for Creaminess

Once your bananas are mashed, scoop in ½ cup of smooth peanut butter (or almond butter if you prefer). Stir it into the mashed bananas until you have a thick, creamy mixture. This is the secret step that gives your Protein Brownie Bites that rich, indulgent flavor without butter or oil.

If you want to keep things lower in fat, opt for powdered peanut butter reconstituted with water — it works surprisingly well and still adds that nutty taste. This is also a good time to make sure your nut butter is stirred well; the natural oils should be fully incorporated so your brownies bake evenly.

Step 4: Stir in the Protein Powder and Cocoa

This step is where your kitchen starts to smell like a chocolate lover’s dream. Add ½ cup of vanilla or chocolate protein powder and ¼ cup of unsweetened cocoa powder to your banana-nut butter mixture. Mix everything together slowly, scraping down the sides of the bowl as you go.

You’ll notice the batter thickening into something dense and fudgy — exactly what we want for this step by step recipe. If the batter feels too dry, add a tablespoon or two of almond milk until it reaches a thick, spoonable consistency. Avoid overmixing here; a few streaks of powder are fine.

This step is also where you can customize the flavor. Want more sweetness? Add a teaspoon of honey or maple syrup. Craving a mocha twist? Sprinkle in a bit of instant espresso powder. For more flavor inspiration, you might like the way we layer flavors in our Strawberry Cheesecake Protein Balls.

Step 5: Portion and Fill the Baking Cups

Grab your prepared muffin tin and divide the batter evenly into the eight cups. This is your Protein Brownie Bites step by step portion control moment — each cup will be a perfect serving size with around 9 grams of protein.

Use a spatula to smooth the tops of each cup, then sprinkle on a few mini chocolate chips if you’re feeling fancy. They’ll melt slightly as the bites bake, giving you that signature brownie “crackly” top. For a little extra texture, you can also add chopped nuts or cacao nibs.

Step 6: Bake to Gooey Perfection

Slide your muffin tin into the preheated oven and bake for about 20 minutes. Keep an eye on them — you’ll know they’re ready when the tops are set and a toothpick inserted in the center comes out mostly clean (a few moist crumbs are perfect).

When you first pull them out, the bites might seem a little soft — don’t panic! That’s what gives them their fudgy texture. As they cool, they’ll firm up beautifully. This baking step by step process makes all the difference between dry and decadent.

Step 7: Cool, Set, and Serve

Once baked, allow your Protein Brownie Bites to cool in the pan for about 10–15 minutes. This step helps them firm up and makes them easier to remove without breaking. Pop them out of the silicone cups (or carefully loosen from the tin) and place them on a wire rack or plate.

Here’s the fun part — serving them exactly how you like. Warm from the oven, they’re gooey and melt-in-your-mouth good. Chilled from the fridge, they taste like chewy protein fudge. Either way, you win.

If you’re meal prepping, this is the time to stash a few in an airtight container for the week. Or, if you’re like me, one batch might not last that long. You can even double the recipe and freeze half for later.

Step 8: Make It a Habit

Now that you’ve made these Protein Brownie Bites step by step, you’ll probably want to keep them on repeat. They’re an ideal snack for busy mornings, pre-workout fuel, or those “I deserve chocolate” moments that happen to all of us.

Key Tips for Making Protein Brownie Bites

Use overripe bananas — they’re sweeter and easier to mash. Stick to smooth nut butter (the natural kind without added sugar is best). If your batter feels too thick, add a tablespoon of almond milk to loosen it up. Let them cool completely before removing from cups to keep their shape. And most importantly — store a few in the freezer. Having a stash of Protein Brownie Bites on hand is like having a secret weapon for those “I need chocolate now” moments.

Storage and Reheating Tips for Protein Brownie Bites

Once cooled, store your Protein Brownie Bites in an airtight container in the fridge for up to a week. For longer storage, freeze them — they thaw quickly at room temperature or in the fridge overnight. To reheat, pop one in the microwave for 10–15 seconds for that freshly-baked warmth. They’ll taste just as good (maybe better) as the day you made them.

FAQs

Can I use a different protein powder? Yes! Whey, plant-based, or collagen protein all work — just note that texture may vary slightly.
What if I don’t like bananas? Try unsweetened applesauce instead, but you might need to add a bit of honey or maple syrup for sweetness.
Can I make these vegan? Absolutely. Use plant-based protein powder and vegan chocolate chips.
Do they really have 9 grams of protein each? Yep, and that’s per bite! These are as nutritious as they are delicious.
