Prepare the Cinnamon Swirl
- Prepare the Cinnamon Swirl
- In a small bowl, combine the brown sugar, ground cinnamon, 1 tsp all-purpose flour, and 1 tbsp melted butter. Mix until it forms a thick, cohesive paste. Set aside.
Prepare the Batter
- Prepare the Batter
- Grease the slow cooker with butter or non-stick spray. Line the bottom with parchment paper for easy removal if desired.
- In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until combined.
- Add the eggs, egg yolk, and vanilla extract. Whisk until fully emulsified.
- Stir in the mashed bananas and sour cream (or yogurt) until just combined.
- In a separate bowl, whisk together the flour, baking soda, baking powder, salt, and nutmeg.
- Gradually add the dry ingredients to the wet mixture. Stir with a spatula until just combined. Avoid overmixing.
Assemble and Cook
- Assemble and Cook
- Pour half of the prepared batter into the greased slow cooker.
- Spoon about two-thirds of the cinnamon swirl mixture over the batter. Gently swirl with a knife 2-3 times to create a marbled effect.
- Pour the remaining batter over the swirl layer.
- Top with the remaining one-third of the cinnamon swirl mixture. Gently swirl once more.
- Cover the slow cooker and cook on low for 4-6 hours or on high for 2-3 hours, until a toothpick inserted in the center comes out clean or with a few moist crumbs.
- Remove the lid and let it cool completely in the slow cooker (about 1 hour) or transfer to a wire rack. Slice and serve.
Notes
For best results, use very ripe bananas for natural sweetness. If you live at high altitude, increase liquid slightly. Freezer-friendly: wrap individual slices and freeze for up to 3 months. Reheat in microwave or oven. Use pure vanilla extract for enhanced flavor.
