Banana walnut muffins recipe

Updated on January 20, 2015

Easy Banana Walnut Muffins with a touch of coffee

Overripe bananas make the best banana walnut muffins or cupcakes. We usually keep a bunch of bananas in the kitchen for our daily dose of potassium and Vitamin C. However, there are days where there are no takers and the nice golden yellow skin begin to develop brown spots looking bruised and unappetizing. Instead of tossing these out and wasting food, I turn these into easy and nutritious breakfast food or snacks of banana walnut muffins.

Follow this one-bowl recipe and you will go bananas over how easy it is to make.

This is a one bowl recipe and all you need is a wooden spatula for hand mixing. Even a non-baker or novice can make this easy banana walnut muffin recipe.

Four overripe bananas - starch turning into sugar - Just waiting to be smashed

As bananas ripen, the starch begin to turn into sugar. That is why overripe bananas taste sweeter, feels softer, but the calorie count remains the same. Warm temperatures also hasten the ripening of green bananas. So when you notice bananas starting to have brown spots, this means they are at the peak of their flavor, sweet, creamy and soft. Ripe bananas are also easier to digest as compared to green bananas are firmer and not as sweet.

Durable bamboo banana hanger - Bananas stay balanced

I have this banana hanger for many years now and it lives up to durability and quality. The hook can be turned to allow the bunch of bananas to be "hooked". This hanger is ideal fo 4-6 bananas and no more to keep it balanced.


Follow the pictorial step-by-step instructions

Step 1. Preheat oven to 350 degrees - Line a 12-cup muffin pan

You may prefer to pour the batter directly to greased muffin pans. I have always opted to using muffin pan liners. This makes cleanup of the pan a cinch and also makes it easier to eat the muffin without messing up your hands --especially kids and grownup kids.

Muffin cup liners cut out cleanup - Muffins or cupcakes are easier to hold and eat

Step 2. Mash 4 overripe bananas with a wooden spoon - Smashed bananas should be lumpy

Bamboo spatulas - renewable and eco-friendly

I stand by bamboo utensils because these are durable, affordable and eco-friendly. Bamboo belongs to the grass family and can withstand being cleaned constantly and also dries quickly.These are also easy to clean and do not need much maintenance like other woods. I use bamboo spatulas for stir-frying, scooping rice, sauteing vegetables, and mixing cake batter.

Prepare 3/4 cup sugar, 1 beaten egg, 1/3 cup melted butter, 1 tsp. pure vanilla extract

Step 3. Add sugar, eggs, melted butter and vanilla into mashed bananas until blended - Add 1 Tbsp. brewed coffee (optional)

I added the brewed coffee from the coffeepot from breakfast. It was a Starbucks medium breakfast blend. You can add your own favorite coffee flavor.

Mixing bowls - a baker's indispensable kitchen helpers - Nesting bowls are great for whisking eggs, mixing batter and easy to store

Measure dry ingredients - 1 1/2 cup all-purpose flour, 1 tsp. baking soda, 1/8 tsp. salt

Step 4. Add flour, baking soda, salt - Mix until dry ingredients are incorporated into banana batter

Step 5. Add 1 cup chopped walnuts - Walnuts can be toasted or raw

Some people do not like walnuts which can be substituted with pecans. Other people do not like nuts at all. But the nuts in this recipe give the banana cupcake the extra crunch.

Step 6. Fill muffin pans 2/3 full

I could have filled these muffin cups with more batter but I did not want these to overflow during baking. Hence, I had to use an extra 6 cup muffin pan. Next time around, I will distribute the batter evenly in the 12 cup muffin pan and make them 3/4 full since the paper liners are slightly taller than each cup.

Step 7. Bake in preheated oven at 350 degrees for 25-30 minutes

Step 8. It is done when toothpick inserted in center comes out clean - That means no wet batter sticking to the toothpick

Step 9. Cool muffins on rack - Great when eaten warm too

Great with coffee, tea, as an afternoon snack or breakfast. If refrigerated, I usually zap each one for 25 seconds on the microwave to make it just warm and moist.

Take this short poll.

      I'm going to try a gluten-free recipe, but haven't yet, so when I bought bananas the other day I gave away enough that very that I thought I'd be able to eat the rest before they get spots.

      Lovely little tutorial!

      @ohcaroline: Oh yes, ripe overripe bananas are great for making smoothies. If you don't want to eat them, drink them.

      I put them in my Bullet with other fruits and veggies. They do well there. I would like to try the muffins though.
