Sheet Cake

My simple sheet cake recipe is so fabulous. It was so good I had to get it out of my house immediately, because I couldn’t stop munching on it every time I passed by the kitchen.

I start with a cake mix. I know some people are anti-mix, but I happen to be all for it from time to time. There are times when you need a great recipe in a pinch and they come in awfully handy for those times. Let’s take a look 🙂

Here’s a look at most of your ingredients. There should be a bag of powdered sugar in the picture.

How To Make Banana Chocolate Chip Sheet Cake

  1. Preheat oven to 350 degrees F. and line 1/2 sheet baking pan with a silpat liner or parchment paper, sprayed with cooking spray.
  2. Place cake mix, egg, butter and mashed bananas into a large mixing bowl. Stir to combine then stir in chocolate chips. Transfer batter to prepared baking sheet and spread evenly almost to edges.
  3. Bake for 25-35 minutes, or until baked through. Remove from oven and let cool for 30 minutes.
  4. To make icing, place powdered sugar, cream and syrup into a large bowl, whisk until smooth and desired consistency. You may add additional cream and or syrup to thin out more if needed. Spread over cake evenly and top with sprinkles if desired. Cut into squares and serve.

While the cake is cooling, work on the frosting. Super simple….powdered sugar, heavy cream and maple syrup. It’s finger licking amazing.

    Nothing wrong with using a cake mix once in awhile…they can be a lifesaver. I usually pride myself on baking entirely from scratch, but there is a place for cake mixes! You take this one to the top with the maple syrup in the icing and those snowball things…a great finishing touch. Thank you!

    Oh wow, Jenny, this looks so fantastic! I used to work on a cruise ship and they made the best banana bread with chocolate chips, but I’m thinking your version with the maple icing would be even better. On my list to make!

    I prefer to make as much as I can from scratch, but in this busy world with families and jobs sometimes it is just a bit more realistic to get a little help from the packaged stuff. I wish I always had homemade chicken stock around but I don’t so I use the boxed stuff. Sheet cake looks great and sounds delicious. I like the maple with the banana. Nice pics and great post.

    What size is the pan? A 9X13? Or 9X9? I don’t really know what a half sheet baking sheet is!! Thanks.

  5. Sommer@ASpicyPerspective

    I had two revelations reading this:

    1. I need to make more sheet cakes.
    2. I need to buy a really big bottle of maple syrup.

    Looks fabulous!

  6. Erika

    This looks delish! Off to test it out with the browning bananas just hanging out in the kitchen! Thanks for the recipe! 😉

  7. Isra {TheFrugalette}

    You had me at maple icing! This looks so easy to make, great for those school bake sales!

  8. Betsy

    Yum! Do the bananas keep the cake moist? I noticed there wasn’t any oil or water that most cake mixes call for. Can’t wait to try!

  9. Julie @ Table for Two

    I love this entire sheet pan of banana chocolate chip cake!! So easy it comes together too! Looks awesome 🙂

  10. Cookbook Queen

    NOthing wrong with a cake mix. I love sheet cakes too…you get so many more servings out of them!!

  11. Rosie @ Sweetapolita

    Wow, Jenny! This looks amazing. There’s something about banana cake that comforts me more than any other variety. And your maple icing looks incredible! xo

  12. Naomi

    For the record Jenny, I would have gladly taken this off your hands! Oh mama this looks and sounds delish!

  13. Caroline @ chocolate & carrots

    I could totally use this for breakfast right now. My coffee just doesn’t taste right with a breakfast burrito…it needs something sweet! 😀

  14. Averie @ Averie Cooks

    Jenny this is so perfect for last minute things or when you have a million bananas to use up! (like I do right now!) A great, moist sheet cake is always a win!
