Banana Nut Muffins with Black Bottoms have to be one of my favorite brunch recipes. They combine two of my most favorite flavors are banana and chocolate. Put them together in a jumbo muffin and the flavor combination is sublime!
This is a great recipe when made in a Jumbo Muffin Tin since it allows enough room to fully enjoy both flavors. For a pure Banana Muffin, check out my Banana Nut Muffins Recipe with Three Toppings.
Why You'll Love This Recipe:

A Fun Surprise
When your guests slice them open they will be pleasantly surprised with a rich chocolate bottom! The pattern is a nice touch and makes for a pretty muffin when sliced.
Step#1: Make the Chocolate Bottoms
First, make the chocolate batter. Then fill each muffin well with just one scoop of batter. If you use a standard-size ice cream scooper, that's a perfect amount.
Skip the Muffin Papers
These muffins are prettier without muffin papers since you'll see the exterior swirl. But spray your muffin cups well (even if it's non-stick!) with baking spray. This will assure an easy release.
Step#2: Make the Banana Nut Batter
The secret to a flavorful banana muffin is a very ripe banana. If your bananas are not very ripe they will not impart much banana flavor or sweetness.
How-To Ripen a Banana Quickly
- Preheat oven to 300F
- Line a sheet pan with foil
- Place unripe bananas on the pan.
- Bake for 10 mins. Then flip
- Bake for another 10 mins until black on both sides
- Allow bananas to cool, then split them open and use as directed
Use a Potato Masher
Bananas are also easier to mash when they are very ripe. A potato masher is a handy tool for mashing bananas into a chunky puree. It works better than a fork.
Top The Chocolate Batter with the Banana Batter
Top each muffin well filled with the chocolate batter, with the banana batter, until it reaches almost the top of the tin. This will allow the muffins the ability to create a nice domed effect once they are baked.
STEP#3: Add Walnuts
I like to add walnuts on top for a bit of crunch, but you could omit them for any allergies or ad some chocolate chips or shredded unsweetened coconut would be great too. If you have extra unsweetened coconut use it to make my Ultimate Coconut Cream Pie recipe.
STEP#4: Bake and Cool
Bake at 400F (200C) for 15 minutes then reduce to 350F (175C) for 5 minutes. The higher temperature up front will force the muffins to rise up and dome on the top, then reducing the temperature prevents them from burning and allows the muffins the chance to fully bake inside.
The Benefits of Cooling
Allow to cool completely before serving. They will be easier to remove from the muffin tin that way. They will set up and be easier to slice too. I also find the flavors of the banana and the chocolate are even more pronounced the cooler the muffins are.

If you need to ripen bananas in a hurry place them on a sheet pan lined with foil and bake at 300F for 20 minutes, flipping them halfway through. They will turn black and be sticky and sweet inside. Perfect for baking!
