Grandpa Z’s Light & Fluffy Banana Cupcakes

This post may contain affiliate links. Please read my disclosure policy.

These cupcakes are a piece of my childhood… something we always had at Grandma and Grandpa’s!  I can remember the smell of the kitchen when my mom would make these… and just how much I loved them!

Below is the actual recipe, which was a cake… and this was typed out by my Grandpa so many years ago on his typewriter.  Grandpa is gone now, but this is something that always reminds me of him.  He was such an amazing Grandpa to all of us grandkids (12 of us including cousins) so this is an extra special recipe that I am excited to share with all of you!

These are great topped with my Nutella Frosting like in the photo or with a lemon cream cheese frosting!

  1. These are delicious. I made a double batch today and will be taking them to a church bazaar. I made banana frosting which intensified the flavor quite a bit. My husband liked them much better then. Just banana, powdered sugar, butter and enough half and half to get to the consistency I wanted.

    1. Thank you for sharing your frosting recipe Susan! So glad you loved these, they’re very dear to my heart!! Have fun at the church bazaar!

  2. Sounds fabulous— Considering the cupcakes will rise while baking, could you recommend how high to fill each cup with the batter to make it bloom fully, yet not overflow?

    Thanks so much!

  3. Just took these out of the oven and they look awesome! I was able to make 16 cupcakes thst are nucekt mounded. I made a badic chicolsye buttercream frosting for them. I really loved seeing Grsmoa Z’s typed recipes! Thanks for sharing.

  4. No oven temp. Is noted in the cupcake recipe. Is it the same as in Grandpa Z’s typed recipe card for the Banana Cake? 375 F?
    Also- I’ve made banana bread, but others may be unsure about the bananas. Assume they need to be mashed with a fork, but the Cupcake recipe only noted 3 ripe bananas. And in the Instructions, #6 notes Stir in bananas.

  5. These sound just like my grandma’s cupcake recipes!!! I will have to make these ones to try out as they sound super yummy!
