Simple Banana Cupcakes with Sour Cream Frosting

This post may contain affiliate links. Read our disclosure policy.

I little bit ago I answered a call for spring cupcake ideas for Reynolds.  I sent in a few ideas and they ended up picking my Simple Banana Cupcakes with Sour Cream Frosting as one of their recipes to feature using their new line of Baked For You® StayBrite® Baking Cups.  They are designed with Staybrite technology, ensuring the colors stays vibrant on the cups – even after baking.  I mean if you are going to get cute baking cups for your cupcakes, you want them to be just as cute after they bake, right?

I selected the design they have with monkey faces and bananas– perfect for a banana cupcake.  You can find the Baked For You® StayBrite® Baking Cups on your baking isle at your grocery store with all the other baking cups.  They were easy to use and worked great.  The design was just as cute and when I placed them in my cupcake tin.  The other thing I love is that the baking cups is they remove easily from the cupcakes when you are ready to eat them.  Nothing bugs me more than having half of my delicious cupcake stick to the baking cup.

These cupcakes are moist and delicious.  The sour cream frosting was the perfect accompaniment.  The sour cream gives the sweet frosting just enough tang.

I also have a giveaway starting today for Memorial Day, so be sure to check it out.

  2. I made your frosting and used it on banana cupcakes from a boxed mix (I also added chocolate chips to the mix which really added a lot). TO DIE FOR! I haven’t tried the cupcake recipe but the frosting was the best frosting I’ve ever had! Thank you. They were a huge hit at my son’s first birthday!

  3. Those cupcake liners are too cute. They ARE perfect for these banana cupcakes!
