What to Gather

3 ripe bananas
2 large handfuls of baby spinach
3 tablespoons milk (dairy or plant-based)
1 large egg
½ cup sugar
1 teaspoon vanilla extract
½ cup full-fat Greek yogurt
3 tablespoons mild oil (canola or vegetable)
1 cup white whole wheat flour (or all-purpose)
1 teaspoon baking soda
⅔ cup cocoa powder
¼ teaspoon sea salt
½ cup dark chocolate chips

Mixing and Baking Directions

Preheat oven to 350°F.
Place milk, ripe bananas, and fresh baby spinach in a blender and blend until mostly smooth; pour into a large bowl.
Whisk in the egg.
Add sugar, vanilla extract, oil, and Greek yogurt to the blended mixture and stir until combined.
In a separate bowl, whisk together flour, baking soda, cocoa powder, and sea salt.
Add the dry ingredients to the wet mixture and gently fold until just combined, avoiding overmixing.
Stir in chocolate chips, reserving a few for topping if desired.
Line a 12-cup muffin tin with liners and scoop batter into each cup, filling about three-quarters full; sprinkle remaining chocolate chips on top if using.
Bake for 18–22 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
Let muffins cool in the pan for a few minutes, then transfer to a wire rack to cool completely.

Pro Tips and Shortcuts

Stick with fresh spinach. Frozen spinach tends to bring too much liquid and stronger flavor which can throw off these chocolate spinach muffins.
Keep leftovers fresh. Store muffins in an airtight container in the fridge for up to five days. If you’re just leaving them on the counter, they’ll last about three days. Freezing is a great option too — they keep for up to three months in the freezer without losing moisture or flavor.
Switch up the add-ins. Don’t limit yourself to chocolate chips — try shredded coconut, chopped nuts, dried fruit, or top with a smear of nut butter. It adds fun new textures and flavors to these muffins.

Easy Swaps and Add-Ins

If you want to make these chocolate spinach muffins just right for your family, here are some simple swaps and add-ins that work beautifully:

Dairy-free: Use unsweetened almond milk (or another plant milk) and swap the Greek yogurt for a dairy-free version—plain or vanilla.
Lower fat: Swap the oil for unsweetened applesauce in equal amounts to get a moist but slightly denser muffin.
Gluten-free: Use a gluten-free baking flour blend one-for-one, but keep an eye on the batter thickness and add a splash of milk if it feels too stiff.
Hide the green more: Dark cocoa powder is your friend for a deeper chocolate flavor that masks spinach. Feel free to add a teaspoon of instant espresso powder too for extra richness.
Mix-ins: Toss in chopped nuts, shredded coconut, raisins, dried cherries, or cacao nibs along with chocolate chips. You can scatter some on top just before baking for an extra nutty crunch.
Flavor twists: Try swirling a spoonful of peanut or almond butter onto the top of each muffin before baking or add ½ teaspoon cinnamon to the dry ingredients for a little warmth.
Adjust the size: Want mini muffins? Bake about 12-14 minutes. Jumbo muffins take closer to 22-26 minutes. Always check doneness with a toothpick!

Storing and Reheating Advice

Here’s how to keep these chocolate spinach muffins fresh and tasty, even if you make them ahead of time:

Room temperature: Let muffins cool completely then store in an airtight container for up to 3 days — perfect for a quick grab-and-go snack.
Refrigerator: Keep muffins in an airtight container for up to 5 days if you want them to last longer. Chilling helps keep dairy and fruit ingredients fresher.
Freezing: Muffins freeze great! Cool fully, then pop them in freezer-safe containers or bags for up to 3 months. Wrapping individually in plastic or parchment before freezing helps avoid freezer burn.
Thawing & reheating: Let frozen muffins thaw at room temperature for 1-2 hours or overnight in the fridge. Warm them gently in the microwave for 15-30 seconds or reheat in a 325°F oven for a crispier top—6-10 minutes if refrigerated, 12-15 if frozen. Cover loosely with foil to keep them moist.
Make-ahead tip: Although the batter is best baked fresh, you can blend the spinach, banana, and milk mixture up to 24 hours ahead and refrigerate it. Just finish the recipe with the remaining ingredients right before baking. Baked muffins also freeze and reheat really well!

Common Questions Answered

Can I use frozen spinach?

It’s best to stick with fresh baby spinach for this recipe. Frozen spinach can add too much moisture and a stronger flavor, which changes the texture and taste of these chocolate spinach muffins.
Can I use frozen bananas?

Yes, just thaw them fully before blending so they mix smoothly with the milk and spinach. While I prefer room-temp bananas for ease, thawed frozen ones work just fine.
How do I know when muffins are done?

Stick a toothpick in the center of a muffin — it should come out clean or with a few moist crumbs. Baking time is about 18-22 minutes for standard muffins; adjust time for mini or jumbo sizes and keep an eye on them.
Can I make these muffins vegan?

Absolutely! Substitute a flax or chia egg (1 tablespoon ground flax or chia mixed with 3 tablespoons water, let sit 5-10 minutes), use plant-based milk, and swap for dairy-free yogurt. The texture will be slightly different but still delicious.
Why are my muffins dense or flat?

Possible issues: expired baking soda, overmixing the batter, or too much moisture from frozen spinach or bananas. Use fresh baking soda, mix just until combined, and stick to fresh spinach to avoid these problems.
Can I reduce the sugar?

Yes, you can dial down the granulated sugar a bit since the ripe bananas already add sweetness. Just know that lowering sugar can affect muffin texture and how sweet they taste, so adjust to your preference.
