Bake up a moist, homemade single loaf of Chocolate Chip Zucchini Banana bread right in your Crock-Pot. No need to heat up the oven or the kitchen! A great snack or dessert!

Slow Cooker Chocolate Chip Zucchini Banana Bread
Garden season is here and I just put my zucchini seeds in the soil this week in anticipation of having a bunch of fresh from the garden zucchini to eat in a ton of different ways.
Of course a classic way to use up the abundance of zucchini from your garden is to make up zucchini bread. But what if you also have a extra banana or two languishing on the counter going brown?
How about mashing that up and adding it to your zucchini bread?
And then let’s go ahead and add some chocolate chips too.
Because…um…CHOCOLATE!
And then because this is a Crock-Pot recipe blog we have to bake it in our slow cooker!
I love baking in my slow cooker because that means I do not have to heat up the oven, which then heats up my kitchen, which then heats up my house. Nope not during the summer when it is hot enough already!
Plus, baking quick breads in the slow cooker like this results in a one loaf of banana bread that is filled with shredded zucchini and studded with chocolate chips that is fantastically moist and delicious!
This recipe as is is dairy free. But I like to serve it as a mid afternoon snack with a little butter or cream cheese.
It works as a dessert or breakfast too!

Frequently Asked Questions
Yes! To make this bread gluten free you can simply swap out the all-purpose wheat flour with Cup 4 Cup gluten free flour. The rest of the recipe stays the same and the finished loaf tastes great!
I have not tried this recipe by replacing ALL of the sugar in it. But, I have been able to cut the sugar quite a a bit by using Splenda products (not sponsored) and sugar free chocolate chips.. To make this chocolate chip banana zucchini bread sugar free you can replace the granulated white sugar with Splenda and the brown sugar with Splenda Brown Sugar blend and use sugar free chocolate chips.
Absolutely! You can add 1/2 cup of either chopped walnuts or chopped pecans right into the batter when you add the chocolate chips.
To make quick work in grating your zucchini I like to use my food processor. But a cheese grater will work too! You do not need to peel the zucchini first, just give them a quick rinse, cut off the ends and then grate them up.

Nutrition

What would you change if you were to cook it in the crock-pot ceramic insert after spraying with non-stick spray? Would you double the recipe or suggest I give it up?
I am sure you can bake it right in the slow cooker insert. But the cooking time might be a little bit less. I would just keep my eye on it so it doesn’t overcook.
Is there a way to cook this in the oven? If so, what should the oven temperature be and for how long?
Sorry Liz, this recipe has not been tested in the oven.
Hi LIz,
If you bake it in the oven, add an extra egg and bake in the oven for 50-60 minutes at 350 degrees until its brown on top and a toothpick inserted comes out clean.
I use light tasting olive oil in place of vegetable oil and add shredded carrots in addition to the zucchini.
I also use Nestles Chocolate morsels in place of the chocolate chips. So good!
