1. For the browned butter, add the butter to a small saucepan and heat it up. Melt the butter and let it cook until small dark specks appear on the bottom of the saucepan. The butter should start smelling slightly nutty. Remove from the heat and let it cool slightly.

2. Preheat the oven to 180°C (350°F). Lightly grease a loaf tin* (about 30x12cm) and line it with a strip of baking parchment. Mash the bananas and set them aside.

3. Add the brown sugar and melted browned butter to a large bowl and mix for a few minutes until well combined. Add the eggs one at a time, mixing well after each addition. Next, add the milk and vanilla extract and mix them in as well. Finally, add the mashed bananas and mix them in. Combine the flour, baking powder, and salt, then add it to the bowl and mix until just combined. Do not overmix! Break the mini Toblerone bars into pieces, add them to the batter, and fold in.

4. Pour the batter into the prepared loaf tin, smooth out the top, and bake the banana bread for about 50-55 minutes – or until a wooden skewer inserted into the center of the banana bread comes out clean. Remove the banana bread from the oven and let it cool down for some time inside the baking tin, then lift it out with the baking parchment and let it cool down completely on a wire rack.
