Ingredients

• 3 very ripe bananas, mashed (about 1 ½ cups): The sweeter they are, the better your muffins will be.
• ⅓ cup melted coconut oil or neutral oil: Adds moisture and tender texture.
• ½ cup pure maple syrup or honey: For natural sweetness.
• 2 large eggs: Helps bind everything together.
• 1 tsp pure vanilla extract: A must for that warm, cozy flavor.
• 1 ¾ cups white whole wheat flour: Gives a nutritious boost while keeping them light.
• 1 tsp baking soda: Our leavening agent for the perfect rise.
• 1 tsp ground cinnamon: The essential warm spice.
• ½ tsp fine sea salt: Balances all the flavors.
• ⅔ cup chopped walnuts: For that classic nutty crunch.
• For the Oat Crumble:
• ½ cup old-fashioned oats: The base of our crunchy topping.
• ¼ cup chopped walnuts: Echoes the flavor inside the muffin.
• 2 Tbsp coconut sugar or brown sugar: Creates those delicious crispy bits.
• 2 Tbsp melted coconut oil: Binds the crumble together.
• ½ tsp cinnamon: Ties the whole muffin together.

Instructions

1. Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with liners or grease it well.
2. In a large bowl, mash the bananas until mostly smooth. A few lumps are just fine!
3. Whisk the melted oil, maple syrup, eggs, and vanilla into the bananas until the mixture is well combined.
4. Gently sprinkle the flour, baking soda, cinnamon, and salt over the wet ingredients. Use a spatula to fold everything together until you no longer see streaks of flour. Be careful not to overmix! Fold in the chopped walnuts.
5. In a small bowl, mix all the oat crumble ingredients with a fork until clumps form.
6. Divide the batter evenly among the 12 muffin cups. They should be about ¾ full. Generously sprinkle the oat crumble over the top of each one, gently pressing it in so it sticks.
7. Bake for 18-22 minutes, or until a toothpick inserted into the center of a muffin comes out clean. Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack.

Variations & Substitutions

• Gluten-Free: Swap the whole wheat flour for a 1:1 gluten-free baking blend.
• Nut-Free: Simply omit the walnuts. You can replace them with sunflower seeds or just leave them out. For the crumble, use seeds or extra oats.
• Vegan: Use flax eggs (2 Tbsp ground flaxseed mixed with 5 Tbsp water, let sit 5 mins) instead of regular eggs. My passion is plant-based cooking, and this swap works beautifully here.
• Add-Ins: Feel like chocolate? Toss in ½ cup of chocolate chips. For a savory breakfast twist, believe it or not, a tiny pinch of flaky sea salt on top of the crumble is amazing.

Pro Tips For Perfect Muffins

• Don’t overmix the batter! Stir until the flour is just incorporated. A few lumps are your friend—they guarantee a tender crumb.
• Those bananas need to be seriously ripe. The blacker the peel, the sweeter and more flavorful your muffins will be.
• Pack that crumble on top. Don’t be shy! It adds fantastic texture.
• Let them rest. Honestly, it’s tough to wait, but letting them cool for a few minutes in the pan makes them much easier to remove.
• For a real breakfast inspo moment, warm them up before serving. It makes all the difference.

Storage & Reheating

Let the muffins cool completely before storing. Keep them in an airtight container at room temperature for up to 3 days. For longer storage, they freeze beautifully for up to 3 months. Just wrap them individually and toss them in a freezer bag. To reheat, pop a frozen muffin in the microwave for 30-45 seconds, or warm it in a 300°F oven for about 10 minutes. The oven method will give you the best, crispiest crumble topping.

Serving Ideas & Pairings

These muffins are a star all on their own with a cup of coffee. But if you’re building a bigger spread, they’re wonderful alongside a fruit salad, a scoop of Greek yogurt, or some scrambled eggs for a more balanced meal. They’re the ultimate breakfast food for a leisurely weekend or a grab-and-go weekday. For a true breakfast buffet, set these out next to a savory breakfast casserole—it’s the perfect sweet and savory combo.

Frequently Asked Questions

• Can I make these into mini muffins? Absolutely! Just reduce the baking time to about 10-12 minutes.
• I don’t have white whole wheat flour. What can I use? All-purpose flour works perfectly here as a 1:1 substitute.
• Are these considered a healthy breakfast recipe? I’d say yes! They’re made with whole grains, natural sweeteners, and fruit. They’re a much better choice than most store-bought options and a great healthy food idea for the whole family.
• Can I use quick oats for the crumble? I don’t recommend it. Old-fashioned oats give the best texture for that crunchy topping.
