Banana Butterfingers Coffeecake

Banana Butterfingers Coffeecake

The idea for this cake came to me when I was about to make my fabulous Banana Streusel Coffeecake for the 5th time this month.

I spotted the unfinished bag of Butterfingers across the room, and BLAMMO!

It hit me!

Banana Butterfingers Coffeecake was born!

It was a blissful conception all the way through to the birthing of this big bad baby!

Just wait until you try this cake!

I am not sure whether you will thank me or damn me, since it is quite dangerous!

It is so very versatile in that it can be made into just about any cake pan you choose.

Cupcakes, Bundt cakes, regular 8″ cake pans to build this into a fabulous layer cake for someone’s birthday!

The possibilities are truly endless; as will be the amount of times you make this recipe!

**I know in the video I said Peanut Butter  Butterfingers coffeecake…but I meant to say Banana!  Woops

It’s ok though because the Butterfingers candy bar IS Peanut Butter!

  1. Hi Gretchen, love this recipe but can’t find coffee anywhere in the recipe, how much do I add. ?

    Love your recipes, I’m making a yellow cake this week-end.

    Thanks for all your hard work

    1. HI Linda! thanks! the confusing part about a “coffeecake” is that there is no actual COFFEE in the recipe, it is simply a term used to describe a breakfast type cake that is typically served with coffee (But this cake is great any time of the day and even without coffee! LOL)

  2. Welcome Back Gretchen! I’m about to try this now, but wanted to drop you a line, before getting started & let you know how I appreciate you sharing your time & talents with us! Bake on Lady!!! Bake on!!!

  3. Yes, we Floridians do have a lot of bananas in our kitchens and freezers.
    After seeing (and hearing) your “banana butterfingers coffee cake” video, I realized that you mentioned “peanut butter” banana butterfingers more than once, so I figured it must be a Freudian slip; therefore I added some peanut butter to your ganache recipe. EXCELLENT.
