Step‑by‑Step Instructions for Peanut Butter Protein Brownie Bites
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This step is crucial as it ensures a perfectly baked texture for your Peanut Butter Protein Brownie Bites. Prepare a muffin tin lined with silicone baking cups for easy release after baking. While the oven heats, you can gather and prepare the other ingredients.
Step 2: Mash the Bananas
In a medium bowl, take 2–3 very ripe bananas and mash them with a fork until you achieve a smooth consistency, though a few lumps are perfectly fine. This will create a naturally sweet base for your brownie bites. The bananas not only contribute sweetness but also moisture, making your bites delectably fudgy.
Step 3: Combine Nut Butter
Next, add in ½ cup of smooth natural peanut butter or almond butter to the mashed bananas. Stir well to ensure that the nut butter is thoroughly mixed in. This step adds creamy richness and enhances the overall flavor of your Peanut Butter Protein Brownie Bites. The mixture should be thick and smooth.
Step 4: Mix in Protein and Cocoa Powder
Gradually add 1 cup of vanilla or chocolate protein powder along with ¼ cup of unsweetened cocoa powder to your bowl. Mix until fully incorporated, ensuring there are no dry spots. If your batter appears too thick, you can adjust its consistency by adding a splash of milk or a milk alternative while stirring.
Step 5: Fold in Chocolate Chips
If desired, gently fold in ½ cup of mini chocolate chips into the brownie mixture. This optional step elevates the delight of your Peanut Butter Protein Brownie Bites, adding bursts of chocolate flavor throughout each bite. Mix carefully, just until evenly distributed without over-mixing.
Step 6: Portion the Batter
Divide the brownie batter evenly among the prepared silicone baking cups, filling each about ¾ full. This ensures even baking and helps the bites rise nicely. You should get around 8 portions from the mixture. Use a spatula to smooth the tops if needed, creating a uniform surface for better baking.
Step 7: Add Toppings
For an extra touch, sprinkle additional chocolate chips on top of each filled cup and optionally add a light sprinkle of sea salt. This contrast in flavors enhances your Peanut Butter Protein Brownie Bites, making them even more irresistible.
Step 8: Bake to Perfection
Place the muffin tin in the preheated oven and bake for approximately 15 minutes. You know they’re done when the tops feel firm to the touch, and a toothpick inserted in the center comes out with a few moist crumbs. Be careful not to overbake, as they will continue to firm up while cooling.
Step 9: Cool Down
Allow the Peanut Butter Protein Brownie Bites to cool in the muffin pan for at least 20 minutes before carefully removing them from the silicone cups. This cooling time is essential for them to set properly, ensuring a delicious chewy texture when you take a bite.
Step 10: Serve and Store
Once cool, enjoy your delicious bites right away or store them in an airtight container at room temperature for up to 5 days. If you’re making them ahead of time, refrigerating them will keep them fresh for up to a week, or freeze for a delightful treat later on.
