Ingredients You’ll Need
Though it seems like a big list, the protein banana bread is actually mixed up pretty quickly- don’t be intimidated!
1:1 Gluten-free baking flour: every gluten-free flour is slightly unique. make sure to use baking flour and not all-purpose.
Ripe bananas: the riper bananas the sweeter the bread so use up all the old ones on the counter! If you have extra, these healthy banana cookies are great too!
Collagen powder: one of the cleanest sources of protein and great for your gut, hair, skin, and nails! Learn more about the benefits of a high protein diet and why you want to amp it up!
Almond flour: make sure to use almond flour and not almond meal for this slow cooker banana bread recipe. It will make it have a smoother, less gritty, texture. Learn the difference between almond flour and almond meal.
Eggs: this helps hold it all together.
Baking soda: it’s a delicate blend of rising and getting air into the banana bread so don’t overlook the ratios.
Baking powder: without this powder, your slow cooker banana bread will be ultra-dense and way too thick.
Apple cider vinegar: this helps balance out the baking soda and acidity levels in the recipe so don’t skip it.
Cinnamon: no protein banana bread would be complete without a dash of cinnamon!
Mini chocolate chips: make sure to use dairy-free, gluten-free chocolate chips as needed. Opt for the mini ones so that you get some gooey chocolate in each bite.
Cane sugar: though the bananas are sweet you do want a bit extra in this recipe.
Non-dairy milk: any dairy-free milk should work. We use homemade hemp milk the most.

How To Make It
- In a large bowl mash the bananas until few clumps remain. Stir in the eggs, apple cider vinegar, and milk.
- One by one add in the remaining ingredients (except chocolate chips) and mix.
- Fold in the chocolate chips and mix again.
- Line a 7-quart slow cooker with parchment paper and pour the mixture in.
- Cover the slow cooker with a tea towel and then the lid.
- Cook on low for 3 hours and remove immediately.

Important Teaching Tips
Banana bread in the slow cooker can be finicky. First off, make sure to line your slow cooker with parchment paper. Not only does this make it easier to remove the high-protein banana bread but it also makes it so you don’t need to scrape a slow cooker!
Place a thick tea towel over the slow cooker before putting the lid on. This helps absorb the moisture from cooking healthy banana bread. If you don’t do this, you end up with soggy banana bread.
Do not “lock” the lid into place, just place it on top of the tea towel.
Don’t overmix your banana bread! Mix until combined and then leave it.
Ideally, remove the high-protein banana bread from the slow cooker for three hours and let it cool. If you let it hang out in the slow cooker on “warm” the outsides tend to get a bit crispy and the texture changes.
This recipe was made in a 7-quart slow cooker and set to “low”. If your slow cooker is smaller, cooking times may be different.
Choosing Collagen Powder
It’s no surprise that this slow cooker banana bread is made with collagen powder!
All the protein without the bloat.
I use collagen powder for amping up protein and boosting gut health.
Learn about the difference between collagen and bone broth as how to increase protein intake.
Honestly, as a busy mom collagen powder just makes it easy to eat more protein and not feel like I’m living off chicken and eggs.
And more protein means more energy, more natural beauty, and feeling your BEST.
Plus, in recipes like this, you can sneak protein into your kids as it’s one of the purest sources.
I grab my collagen from Perfect Supplements because they source their collagen from pasture-raised (grass-fed) cows. So, I trust it.
Grab some collagen powder and use code mamabear10 to save some money.
Easy to mix, this collagen powder adds a protein punch to anything you pair it with. Made from pasture-raised (grass-fed) cows there are no pesticides, hormones, or filler agents. Just put collagen protein. Use code mamabear10 to save money on your next order.
