Banana Cake with Fluffy Peanut Butter Frosting

Banana Cake with PB Frosting

When my mom begins an email with, “gotta share these two new and fabulous recipes with you!”, I know I’m in for a treat.

The summer humidity where my mom lives makes bananas ripen quicker than they get eaten. After making multiple loaves of banana bread, she went searching for a different recipe to utilize her browning nanners and a spare cake mix. What she found was a simple and versatile (you could use any flavor cake mix) recipe that yields a moist, tender cake with a mild, but distinct, banana flavor.

My mom and I share an affinity for banana bread and peanut butter sandwiches. With that in mind she found a fluffy peanut butter frosting to adorn the banana cake and mimic the taste of those tasty sandwiches we so love.

The result of these two new recipes is indeed fabulous!

Banana Cake with Peanut Butter Frosting

Banana Cake {source}

  • yellow cake mix
  • eggs, oil, and water (ingredients listed on the box to make cake)
  • 2 overripe bananas
  • 1 tsp baking soda

Create cake batter according the package instructions. In a separate bowl, mash the two bananas. Mix the baking soda into the bananas until thoroughly mixed – it will look lighter and slightly foamy. Add banana mixture to the cake batter and stir until combined.

Pour banana batter into a greased 9 x 13 pan. Bake according to package directions. Let cool completely and frost with Fluffy Peanut Butter Frosting (below).

Fluffy Peanut Butter Frosting {adapted from All Recipes}

  • 1/2 cup butter, softened
  • 1 cup creamy peanut butter
  • 1 1/2 cups powdered sugar
  • 3 tablespoons heavy cream

Beat butter and peanut butter together until well combined. Beat in the powdered sugar. Frosting will be very dense and thick.  Add heavy cream and beat until fluffy and spreadable. Spread on cooled Banana Cake.


Peanut Butter & Trail Mix Sandwich

PB and Trail Mix sandwichCostco is a dangerous place. So many delicious things and in such large quantities. I try not to go when I’m hungry or I’ll come home with mounds of unnecessary goodies that called my name, either from a sample cup or my ravenous wanderings up and down the aisles.

When we first moved to CDA, I did one of those ravenous wanderings and ended up bringing home a large package of trail mix {peanuts, almonds, M&Ms, and raisins}. We waited two weeks for our things to arrive so trail mix seemed like a decent choice since we were devoid of cookwar

Trail MixI adore that particular trail mix, especially the raisins which seem to be perfectly firm and salty. A few weeks ago, I noticed we still had the remnants of that bag of tasty trail mix. Inspiration struck at the sight of the last handful of nuts, chocolate, and dried fruit.

Seemed like peanut butter and the ingredients of that trail mix would be a wonderful combination. Most of the time I eat my peanut butter by the spoonful {we all know how I feel about peanut butter}, but my other favorite vehicle for peanut butter is toasted bread. A peanut butter and trail mix sandwich. Yes!

PB and Trail MixThe textural and flavor elements of this sandwich are addictive. Crunchy nuts, slightly salted and chewy raisins, and the crispy sweet bursts of chocolate. I used creamy peanut butter {which isn’t my norm} but crunchy would work well, too

Peanut Butter and Trail MixIf you didn’t happen to have pre mixed trail mix, create a custom mix. Raid your pantry for nuts, dried fruit, and sweets. Craisins, yogurt covered raisins, white chocolate chips, toasted pecan, or chopped macadamia nuts would be lovely in this sandwich. Get creative.

Train Mix SandwichPeanut Butter & Trail Mix Sandwich

  • 2 slices of bread, toasted
  • 2 Tablespoon peanut butter
  • 1/3 cup trail mix

Roughly chop the trail mix. Spread one piece of toast with peanut butter. Sprinkle trail mix over peanut butter. Place second piece of bread on top of trail mix. Press slightly to adhere trail mix to peanut butter.

Yield: 1 highly addictive sandwich

What’s your favorite thing to put on a peanut butter sandwich?

Dear PB {31 Days of Letters}

Dear Peanut Butter,


How do I love thee?  Let me count the ways…

I love you smooth.

I love you crunchy.

I love you made of honey roasted peanuts, ground in my food processor.

I love you before a workout, with an apple, or as a midnight snack.


I love you spread on toast or eaten from a spoon.

I love breaking into the glassy suface of a new jar.

I love you with chocolate chips, with celery and raisins.

I love you natural and processed.

The only thing I don’t love is when I get to the bottom of the jar.
