Let's Talk About These Peanut Butter Banana Cupcakes

✓ Texture: My goal was to make sure these cupcakes didn't turn out dense like muffins or banana bread, which can be difficult when you're using bananas in a baked recipe– but it can be done! You'll get soft, cake-like banana cupcakes every time by doing these things: A) bringing your cold ingredients to room temperature before mixing, B) using real buttermilk (not a homemade substitute), and C) using oil instead of butter.

Flavor: It was also really important to me that both the peanut butter flavor and the banana flavor each held their own in these cupcakes. They are both bold and dominant flavors, but they harmonize perfectly in this recipe and pair well with the chocolate frosting on top.

Skill Level: I rarely post a recipe that isn't achievable for even the most novice home chef, and these peanut butter banana cupcakes are no exception. Use ripe bananas, bring your  cold ingredients to room temperature, follow the step-by-step directions in this post, and you'll get soft and fluffy cupcakes with a delicious, fork-tender crumb.

1-2-3 Recipe Tips for Success

  Mashing the Bananas. I make a lot of banana treats, including: my mom's famous chocolate chip banana bread, Banana Biscoff Donuts, and banana pancakes with peanut butter syrup. Here's my #1 tip: use a whisk or a your mixer to mash the bananas!  It makes the process a no brainer, and then you can just add your other ingredients straight into the same bowl without dirtying a separate dish. A sturdy fork works well  for mashing too as long as your bananas are very ripe.

Use Overripe Bananas. The perfect bananas for baking are a little soft with lots and lots of brown spots. This means the banana is sweet and will mash well (without a lot of lumps). 

 Bring Cold Ingredients to Room Temperature. If you want soft and fluffy cupcakes, this step is a must. If you forget to set ingredients out on the counter ahead of time, there are still ways of bringing their temperature down. Place eggs in a bowl of warm water to quickly bring them to room temperature. For ingredients like sour cream and Greek yogurt, I will sometimes place them in a ziplock bag and weigh them down in a bowl of warm water. Once the temperature is right, I just snip a corner of the bag and squeeze the contents into the mixing bowl.

Chocolate Peanut Butter Frosting

This Chocolate Peanut Butter Frosting is rich and indulgent, but it's also light and creamy at the same time. It pipes and spreads like a dream, and it tastes ridiculously good. I used this  Ateco Open Star Tip for these cupcakes.

It's chocolate and peanut butter, but not in an in-your-face kind of way. The peanut butter isn't subtle, per se. But you won't be dying for a glass of milk after one taste if you know what I mean. It's so light and fluffy that the peanut butter chocolate combo doesn't overwhelm your tastebuds.
