Directions
<ol class="no-list-style"> <li class="MethodStepper"> <h4 class="step-title">Step 1</h4> Preheat your oven to 190°C. Line a 12-cup muffin tin with paper liners or spray with non-stick cooking spray. This preparation ensures your muffins won't stick and will release easily after baking. </li> <li class="MethodStepper"> <h4 class="step-title">Step 2</h4> In a large bowl, mash the bananas thoroughly with a fork until smooth with just a few small lumps remaining. Riper bananas will provide more natural sweetness and a stronger banana flavor, so choose ones with plenty of brown spots for best results. </li> <li class="MethodStepper"> <h4 class="step-title">Step 3</h4> Add eggs, oil, milk, and vanilla to the mashed bananas. Whisk until the mixture is well combined and smooth. The oil will ensure your muffins stay moist even days after baking, while the eggs provide structure and protein. </li> <li class="MethodStepper"> <h4 class="step-title">Step 4</h4> In a food processor, pulse 100g of the rolled oats until they reach a flour-like consistency. This creates oat flour which adds a tender texture while maintaining the nutritional benefits of whole oats. </li> <li class="MethodStepper"> <h4 class="step-title">Step 5</h4> In a separate bowl, combine the ground oats, remaining 50g whole rolled oats, whole wheat flour, protein powder, brown sugar, baking powder, baking soda, salt, cinnamon, and nutmeg. Whisk thoroughly to eliminate any lumps, especially from the protein powder, which can sometimes clump. </li> <li class="MethodStepper"> <h4 class="step-title">Step 6</h4> Gently fold the dry ingredients into the banana mixture just until combined. Be careful not to overmix – stopping when no dry streaks remain will ensure tender muffins. Overmixing develops gluten, which can make your muffins tough. </li> <li class="MethodStepper"> <h4 class="step-title">Step 7</h4> If using nuts, fold them in now with just a few strokes. The batter should be thick but scoopable – if it seems too dry (protein powders can vary in absorbency), add 1-2 tablespoons more milk. </li> <li class="MethodStepper"> <h4 class="step-title">Step 8</h4> Divide the batter evenly among the prepared muffin cups, filling each about 3/4 full. Use an ice cream scoop for uniform portions, which helps ensure even baking times. </li> <li class="MethodStepper"> <h4 class="step-title">Step 9</h4> Bake in the preheated oven for 18-22 minutes, until the tops are golden brown and a toothpick inserted into the center comes out clean or with just a few moist crumbs. For bakery-style domed tops, start with a higher temperature of 220°C for the first 5 minutes, then reduce to 190°C for the remaining time. </li> <li class="MethodStepper"> <h4 class="step-title">Step 10</h4> Allow the muffins to cool in the tin for 5 minutes (they're still setting internally during this time), then transfer to a wire rack to cool completely. The muffins will keep at room temperature in an airtight container for 2-3 days, or freeze for up to 3 months for convenient grab-and-go breakfasts. </li> </ol>
Chef’s Notes
A few helpful details for making this recipe.
Can I substitute the protein powder in banana oat muffins?
Yes, you can substitute protein powder with an equal amount of additional flour (whole wheat or oat flour). However, this will reduce the protein content. Alternatively, use collagen powder or substitute half the amount with ground flaxseeds or chia seeds for different nutritional benefits.
How do you achieve bakery-style domed tops on protein muffins?
For perfect domed muffin tops, start baking at a higher temperature (220°C) for the first 5 minutes, then reduce to 190°C for the remainder. Fill muffin cups at least 3/4 full, ensure your baking powder and soda are fresh, and avoid overmixing the batter to achieve that classic rise.
How long do homemade banana protein muffins stay fresh?
Homemade banana protein muffins will stay fresh for 2-3 days at room temperature in an airtight container. For longer storage, refrigerate for up to a week or freeze for up to 3 months. To refresh, microwave for 15-20 seconds or warm in the oven for a few minutes.
