Banana Chocolate Muffins with Olive Oil

Bake at 355 and watch the edges—they go golden before the tops even know what’s happening. Three ripe bananas mashed, not quite smooth, a little lumpy on purpose. Chocolate chips scattered on top before it hits the oven so they melt just right into the dome. Takes 40 minutes total if you move through it, 15 to prep, 25 in the oven where you basically ignore it.

Why You’ll Love These Banana Chocolate Muffins

Makes 18 muffins. One batch. Done.

They stay actually moist—not cake-moist, muffin-moist. The olive oil does something butter doesn’t. Not sure what exactly.

Cold the next day, maybe better. Breakfast or dessert. Nobody cares which one you’re calling it.

The chocolate doesn’t sink. It stays scattered through, mixed with a little on top. You get it in every bite, not just at the bottom like muffins usually do.

Olive oil instead of butter cuts the richness without making it taste like health food. Still tastes like a muffin.

What You Need for Banana Chocolate Chip Muffins

Two and a half cups all-purpose flour. Not cake flour. Not bread flour.

Two thirds granular sugar and half a cup of light brown sugar packed down. The brown one matters—it’s got molasses in there, keeps things soft.

Baking powder. Baking soda. Salt. A teaspoon of cinnamon. These all go together first, whisked separate, so they hit the batter evenly.

Three bananas, actually ripe—skin has brown spots. Green ones won’t work. Too starchy. Mash them with a fork, leave some lumps. The lumps actually help. They hold moisture.

A third cup olive oil. Not the fancy kind. The regular kind. Vanilla extract—one teaspoon. Two eggs, large. One cup semisweet chocolate chips. You’ll use three quarters in the batter, scatter the rest on top.

How to Make Banana Chocolate Muffins

Heat the oven to 355. Line two muffin tins with 18 liners total. Don’t grease them. The liners handle it.

Combine the dry stuff—flour, granular sugar, baking powder, baking soda, salt, cinnamon—in a medium bowl. Whisk it till it looks even. Set it aside.

Mash the bananas in a small bowl till mostly smooth. Some texture’s fine. Add the olive oil, vanilla, eggs, and brown sugar. Stir it together gently. This part matters. Overmix and it gets tough. Just blend it till you can’t see the egg anymore.

Pour the wet into the dry. Use a sturdy spatula and fold. Fold again. Stop when you still see dry streaks. That’s the moment. Don’t keep going. Fold in three quarters of the chocolate chips carefully.

Scoop the batter into the liners till each one’s about three quarters full. The dome needs room to rise without spilling over the edge.

Scatter the rest of the chocolate chips on top. Press them in just a little so they stay put and don’t slide off when it gets hot.

How to Get Banana Chocolate Muffins Crispy on Top

Bake for 23 to 27 minutes. Watch the edges—they’ll turn golden first. That’s normal. The tops should spring back a little when you touch them lightly with your finger.

The toothpick test works here. Stick one in the center. It should come out clean or with just a few moist crumbs stuck to it. If it’s wet, give it two more minutes. If it’s bone dry, you went too far—lower the temp next time.

They keep cooking a tiny bit after you pull them out because they’re still hot. Don’t panic if the toothpick’s still slightly underdone. They’ll set as they cool.

Banana Muffins Tips and Common Mistakes

Cool them completely in the pan before you unwrap them. Warm muffins are soft inside. They’ll literally fall apart if you pull them out hot. Give them at least an hour. They firm up as they cool and stop being weird about it.

Store leftovers in an airtight container. They stay moist for two days. Freeze them wrapped individually if you want them longer. They thaw fast—maybe 20 minutes on the counter. Or eat them frozen. Works both ways.

Don’t use brown bananas that are almost black. That’s when they’re too sweet and too soft. The muffins get gluey. You want brown spots, not a solid brown peel.

The olive oil is weird the first time and then it’s not. It makes them softer, less crumbly. Butter would make them tighter. If you swap it, use the same amount. It’ll work. Won’t be the same thing, but it works.

Mix the dry ingredients separately first. This isn’t just a kitchen rule thing. If you dump everything together, the baking soda concentrates and you get little pockets of too-salty taste.

Total:

40 min

Servings:

18 servings

Ingredients

• 2 1/2 cups all-purpose flour
• 2/3 cup granulated sugar
• 1 tablespoon baking powder
• 3/4 teaspoon baking soda
• 1/2 teaspoon salt
• 1 teaspoon ground cinnamon
• 3 large ripe bananas, mashed
• 1/3 cup olive oil
• 1 teaspoon vanilla extract
• 2 large eggs
• 1/2 cup light brown sugar, packed
• 1 cup semisweet chocolate chips, divided

Method

1. 1 Preheat oven to 355F. Line two standard muffin tins with 18 paper liners—skip grease; liners good here.
2. 2 In medium bowl, combine flour, sugar, baking powder, baking soda, salt, cinnamon. Whisk to combine evenly. Set aside.
3. 3 In small bowl, mash bananas with fork till mostly smooth but a few lumps don't hurt the texture.
4. 4 Add olive oil, vanilla, eggs, light brown sugar to bananas. Stir just till blended. Don’t overwork; batter gets tough otherwise.
5. 5 Add wet mixture to dry ingredients. Fold gently with sturdy spatula till just combined—still some dry streaks better than overmixed batter. Fold in ¾ cup chocolate chips carefully.
6. 6 Divide batter evenly among liners. Fill ¾ full is key for good dome rise without overflow.
7. 7 Scatter remaining chocolate chips on tops, press slightly to set them in place.
8. 8 Bake 23-27 minutes. Watch for golden edges; tops spring back lightly when touched. Toothpick test essential—should come out clean or with few moist crumbs.
9. 9 Let cool completely in pan before unwrapping muffins. Warmer muffins—too soft inside, fall apart.
10. 10 Store leftovers airtight; they keep moist 2 days. Freeze for longer.

Frequently Asked Questions About Banana Chocolate Muffins

Can I use frozen bananas? Thaw them first. They’ll be wetter. Drain some of the liquid off before you mash them or the batter gets soupy.

What if I don’t have olive oil? Vegetable oil works. Coconut oil works. Butter works—use the same amount, melted. They’ll taste a little different. Colder muffins if you use butter. Less moist, more cake-like.

Why did mine sink in the middle? Oven temp might be off. Or you didn’t bake long enough. The centers need that full 25 minutes to set. A toothpick should come out clean.

Can I make moist banana chocolate chip muffins without baking soda? Not really. You need the baking soda for the rise. Baking powder alone won’t get you that dome.

How long do banana chocolate muffins stay fresh? Two days in a container. After that they start drying out. Freeze them if you want them longer—wrap them individually in plastic wrap, throw them in a bag. They’ll last weeks. Thaw on the counter.

Can I add more chocolate chips? Sure. Go up to a cup and a half total if you want. The batter holds it fine. Just don’t skip the three quarters mixed in—you need the structure.
