My good friend, Carol, mailed me this banana bread snack cake recipe on an index card along with some local treats from her area to try. She said it’s one of her new favorites and a must try. 

Carol first saw the recipe on Let’s Dish, but changed it up by adding walnuts and chocolate chips. I don’t know about you, but when I hear bananas, walnuts, and chocolate, I automatically think of Ben and Jerry’s Chunky Monkey ice cream. So I renamed this banana bread snack cake Chunky Monkey Snack Cake.

In addition, I also made a couple of other changes to the recipe. I prefer to mix the dry ingredients first so they’re ready and waiting to be used. I also prefer to line my pan with aluminum foil so it’s easy to lift out of the pan.

Once the batter’s in the pan, you sprinkle granulated sugar on top of the batter. As the banana bread bakes, the sugar melts and gives the top a delightful crackly top.

Baking Tip

Lately, I’ve been using the Reynold’s Wrap non-stick foil. Have you tried it yet?

If you fold the aluminum foil around the outside of the pan first, then remove it, it fits easily inside the pan. 


Carol added mini chocolate chips, but I decided to use regular semi-sweet chocolate chips so it would have that more chunky feel. Either would work well in this recipe.

Danelle used pecans instead of walnuts. My husband loves walnuts in his banana bread, but if you prefer pecans, definitely use those instead.

You can use either a 8-inch or 9-inch square pan when making this recipe. I used an 8-inch square pan and cut the cake into 2-inch pieces which is the perfect snack size. If you’re serving it for dessert you may want to cut it into larger pieces. Here’s a good tutorial for cutting nice even pieces

My husband and I were both crazy about this cake too. Thanks so much for sharing it with us Carol!

If you love banana bread, you’re definitely going to want to bake this asap.
