Now these muffins are a weekly staple. They’re soft, naturally sweet, and perfect for little hands. And because they’re made without dairy, nuts, or refined sugar, they’re safe for lunchboxes, class snacks, and even picky eaters. They freeze beautifully, reheat quickly, and honestly—adults love them too.

How to Make Spinach Banana Hulk Muffins (Step-by-Step)
These muffins come together in one blender and a single mixing bowl—no fancy equipment or folding techniques needed. You’ll go from overripe bananas to warm, vibrant green snacks in under 30 minutes.
Step 1: Preheat and Prep
Set your oven to 350°F (175°C). Line a muffin tin with silicone liners or lightly grease with coconut oil. These Spinach Banana Hulk Muffins can stick, so don’t skip this part.
Step 2: Blend the Greens and Wet Ingredients
In a high-speed blender or food processor, combine:
- 2 ripe bananas
- 1 cup fresh baby spinach (packed)
- ½ cup unsweetened applesauce
- 1 egg or flax egg
- 1 tsp vanilla extract
- 2 tbsp maple syrup (optional)
Blend until fully smooth and creamy. No spinach chunks should remain.

Step 3: Stir in Dry Ingredients
In a large bowl, mix:
- 1½ cups rolled oats (or oat flour)
- 1 tsp cinnamon
- 1 tsp baking powder
- ½ tsp baking soda
- ¼ tsp salt
Pour the green mixture into the dry ingredients and stir until just combined. Don’t overmix.
Step 4: Add Optional Mix-ins
Now’s the time to fold in mini chocolate chips, chia seeds, or hemp hearts—if using. These add flavor and texture but aren’t required.

Step 5: Fill the Muffin Cups
Divide the batter evenly between 10–12 muffin cups. Fill nearly to the top, as these Hulk muffins don’t rise too much.

Step 6: Bake and Cool
Bake for 18–20 minutes or until a toothpick comes out clean. Let cool in the pan for 5 minutes before transferring to a wire rack.
Once cooled, you can freeze these Spinach Banana Hulk Muffins for up to 2 months. They reheat beautifully and make fantastic on-the-go breakfasts or school-safe snacks.
How to Store Spinach Banana Hulk Muffins
These Spinach Banana Hulk Muffins are perfect for batch prepping ahead of busy weeks. They store beautifully and hold up well in lunchboxes, snack bags, or even your freezer.
Room Temperature:
Keep muffins in an airtight container at room temp for up to 2 days. Make sure they’re fully cooled before sealing to prevent moisture buildup.
Refrigerator:
For longer freshness, store them in the fridge for 4–5 days. Warm them slightly in the microwave for 10–15 seconds before serving for a just-baked feel.
Freezer:
These muffins freeze exceptionally well. Freeze them flat on a baking tray, then transfer to a freezer-safe bag or container. They’ll last up to 2 months. To reheat, microwave straight from frozen or thaw at room temp for packed lunches.
Allergy-Friendly Variations
These muffins are already dairy-free and nut-free, but there are easy ways to adjust the recipe for other dietary needs without sacrificing taste or texture.
Egg-Free (Vegan Option):
Replace the egg with a flax egg (1 tbsp ground flax + 3 tbsp water, rested for 5 minutes). Works perfectly in this moist batter.
Gluten-Free:
Use certified gluten-free rolled oats or oat flour. Most oats are naturally gluten-free but check the label to avoid cross-contamination.
No Sugar Added:
If your bananas are extra ripe, you can omit the maple syrup entirely. The natural sweetness from the fruit and applesauce is often enough—especially for toddlers.
Add-In Ideas:
Mix in hemp hearts, chia seeds, or even mini dairy-free chocolate chips for variety. You can even top with pumpkin seeds before baking for a crunchy finish.
