This caramelized banana skillet cake recipe is packed with protein, thanks to help from the Stonyfield OP protein smoothie that’s used in place of milk. It’s moist on the inside and has a crispy exterior, giving structure for the caramelized bananas that sit on the top of the cake. It’s perfect for breakfast, brunch, or an afternoon snack!
I’m not sure if you’ve noticed it at your grocery store yet, but Stonyfield has released a line of protein smoothies, called OP. Because I’m a #StonyfieldBlogger, they were nice enough to send me a few bottles so that I could do some recipe development with them. The three flavors available right now are vanilla, chocolate, and strawberry.
I tried each of the flavors “straight up” from a glass so that I could have a good idea of the flavor.  It wasn’t much of a surprise that the chocolate was my favorite.  As far as recipe development goes, vanilla seemed to be the most versatile, because it’s easily subbed into a recipe whenever milk is normally used, so I decided to use it in the banana skillet cake.
One of my favorite kitchen cooking pans is my cast iron skillet. I have a small, 6-inch one that I use for small batch fudgy brownies, and a larger, 10-inch pan that I use to sear steak and for my skillet bacon cornbread.  Oh, and I just ordered this 12-inch Lodge cast iron skillet because it’s on sale for almost 40% off the normal retail price. Score yourself one before they run out!
I hope you enjoy this banana skillet cake!

Caramelized Banana Skillet Cake Recipe
Ingredients
- 4 ounces (.5 cup) unsalted butter, melted and cooled, plus 3 tablespoons
- 11 ounces (1.5 cups) Erythritol or granulated sugar (organic sugar brings a great molasses flavor to the cake!)
- 3 ounces (.5 cup loosely packed) brown sugar, plus 1/3 cup
- 2 large eggs
- 2 teaspoons vanilla extract
- 8.8 ounces (2 cups) all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 teaspoon ground cinnamon
- 3 large ripe bananas, mashed (about 1.25 cups) + 2 bananas, sliced
- 1/3 cup Stonyfield vanilla OP smoothie (or milk)
- Optional garnish: confectioner's sugar
Instructions
- Heat oven to 400 degrees F. In a small bowl, mix together flour, baking powder, baking soda, salt and cinnamon. Set aside.
- Heat a 10-inch or 12-inch cast iron skillet over medium heat. Add 3 tablespoons of butter, and let sizzle and melt, then whisk in 1/3 cup brown sugar and add in the sliced bananas in a single layer. Cook for 2-3 minutes, then remove from heat and set aside while making batter.
- In a large bowl, whisk together melted butter and sugars. Once combined, whisk in eggs and vanilla until smooth. Add in dry ingredients, stirring to bring together, then add in mashed bananas and mix. Add in OP smoothie or milk and mix until combined. Pour batter over bananas in skillet and spread evenly. Bake for 30-35 minutes, or until cake is golden and set in the middle. Let cool for 5-10 minutes.
- If desired, dust with confectioner's sugar and serve warm with a scoop of ice cream.

Arman says
Becca, I am going to pray, cast spells, do whatever it takes to turn my green bananas yellow. This needs to be made!
Chef Becca says
Haha! Oh my gosh, Arman, if you could only know the amount of times that I’ve made a mad dash to the market for bags of over ripe bananas. It’s a bit pathetic. I’ve since started buying more than I think I’ll use so that I can peel the over ripe ones, bag them, and toss them into the freezer for instances just like this! It’s a deep seated infatuation that I have for all things banana bread, and this skillet cake is no exception.

This cake looks and sounds phenomenal! I’m a huge yogurt fan and I’ll be looking for the Stonyfields OP!
Chef Becca says
Thanks, Laura! The Stonyfield OP is rolling out into stores slowly, but you can look for it in the dairy case.

Laura says
What a fabulous way to use my new Lodge cast iron skillet! I can’t wait to try this Becca. I’m a huge fan of Stonyfield yogurt and just might try using their plain nonfat yogurt instead of the protein shake or milk. I love carmelized (upside down) cakes and only since I’ve gotten a cast iron skillet have I had the tools to make one. Most fun few dollars I’ve spent in a while.
Chef Becca says
Cast iron skillets are awesome, Laura, and I hope you love using yours! Using yogurt instead of the smoothie in this recipe will work perfectly. Before the smoothies were available, I used to sub yogurt for milk and sour cream whenever possible.
I hope you enjoy the recipe!
Farrah says
This looks delicious! <3 I coincidentally just made a banana protein cake (but in my rice cooker), so I'm gonna have to finish that first, but…can't wait to try this out! :]!
