Step 1

Preheat the oven to 350 °F / 180 °C / Gas Mark 4, no fan.

Step 2

Prepare all the ingredients.

Step 3

Prepare a 9x5-inch loaf pan (23x11cm)* by buttering it and lining with parchment paper.

Step 4

In a small pot melt the butter, take it off the heat and leave to cool.

Step 5

In a small bowl, mix the flour, salt, baking powder, and baking soda together. Set aside.

Step 6

Add the eggs and sugar to a mixing bowl, whisk with a mixer fitted with a whisk attachment on medium-high speed for 5 minutes until the mixture is pale, light and foamy.

Step 7

Add the mashed bananas, vanilla extract, and melted and slightly cooled butter, mix until just combined.

Step 8

Sieve the flour mixture into the batter, stir in with a spatula, until partially combined.

Step 9

Add the chocolate (broken into smaller pieces) and a little over a cup of blackberries, fold in, taking care not to over mix.

Step 10

Pour batter into the prepared loaf pan.

Step 11

Lay the remaining blackberries on the top.

Step 12

Bake for about 1 hour, or until a cake tester comes out clean. It may run longer or shorter in your oven. After about 50 minutes, check if the top is not browning too much, if it is - cover it loosely with a piece of aluminum foil.

Step 13

Enjoy!
