Method
Prepare the Cream Cheese Filling
- In a medium bowl, beat the softened cream cheese and granulated sugar together using a hand mixer until completely smooth and lump-free.
- Beat in the egg yolk and vanilla extract until just combined. Avoid overmixing to prevent separation. Set aside.
Mix Dry Ingredients
- In a large bowl, whisk together the flour, baking soda, salt, and cinnamon (if using).
Prepare Wet Ingredients
- In a separate bowl, mash the ripe bananas until mostly smooth with some lumps for texture.
- Add the melted butter, granulated sugar, brown sugar, eggs, sour cream (or Greek yogurt), and vanilla extract to the mashed bananas. Whisk until just incorporated.
Combine Wet and Dry Ingredients
- Pour the wet ingredients into the dry ingredients. Mix gently with a rubber spatula until just combined. Do not overmix.
Layer and Cook in Slow Cooker
- Grease the inside of your slow cooker or line it with parchment paper for easy removal and to maintain loaf shape.
- Pour half of the banana bread batter into the prepared slow cooker and smooth the top.
- Carefully spoon the cream cheese filling onto the batter layer, spreading evenly but leaving a small border around the edges.
- Pour the remaining banana batter over the filling and smooth the top.
- Use a butter knife or skewer to gently swirl the batter once or twice lengthwise to create a marbled effect. Avoid over-swirling to maintain distinct layers.
- Cover the slow cooker and cook on high for 1.5 to 2 hours, or until a toothpick inserted into the banana bread section (not the cheese center) comes out clean. Cooking time may vary by slow cooker model; check after 1 hour.
Cool and Serve
- Remove the lid and let the loaf cool in the slow cooker for 15-20 minutes. Carefully remove using the parchment handles and transfer to a wire rack to cool completely before slicing.
Notes
For best results, use fully ripe bananas for maximum sweetness and moisture. Store cooled loaf in an airtight container in the refrigerator for up to 5 days or freeze slices for up to 3 months. Reheat slices in the microwave for 15-20 seconds. This slow cooker method yields a soft, dense texture; if you prefer a more traditional oven-bake, bake in a greased loaf pan at 350°F for 55-70 minutes. Experiment by adding chopped walnuts or pecans to the batter for extra crunch.
