How To Make Slow Cooker Banana Bread
Step 1: In a large bowl, mash the bananas until mostly smooth. Stir in the eggs, apple cider vinegar, and non-dairy milk.
Step 2: Add the dry ingredients (flours, baking soda, baking powder, cinnamon, sugar, and collagen) and mix until just combined.
Step 3: Fold in mini chocolate chips, then transfer the batter to a 7-quart slow cooker lined with parchment paper.
Step 4: Cover the slow cooker with a thick tea towel, place the lid on top (do not lock), and cook on low for 3 hours. Remove immediately and let cool briefly before slicing.
Expert Tips
Line the slow cooker with parchment paper for easy removal and cleaner cleanup. Placing a thick tea towel over the cooker before setting the lid helps absorb excess moisture and prevents sogginess. Do not lock the lid; simply rest it on the towel.
Avoid overmixing—stir until ingredients are combined. Remove the loaf at three hours and cool outside the cooker; leaving it on warm can change the texture and make the edges dry or crispy.
Storage: Once cooled, store the bread in an airtight container at room temperature for one day or refrigerated for 3–4 days. Rewarm briefly before serving.
