Warm an oven at 180 degrees C
Take 50 grams of sugar in a pan and caramelise over low heat
When it starts browning, mix in 2 tbsp of mashed banana and mix well until fully caramelised
The above steps are optional. You can simply use all the sugar and bananas in the recipe below instead but doing the above gives it a crunchy, smoky feel. Keep an eye on the sugar mix as it can harden quickly and make sure you don’t burn yourself handling it
Mix the rest of the sugar, melted butter, remaining bananas, caramelised mix (optional), vanilla and rose extracts and mix well
Sift the flour and cocoa powder into the mix and whisk well
Line a brownie pan with the reserved butter
Sift the reserved cocoa powder evenly across the pan
Pour the brownie mix and gently tap the pan so it spreads across evenly
Dot the top of the mix with blobs of peanut butter, using a wet palate knife (or a flat knife), spread it across for a marbled effect
Bake in the oven for 20 minutes, turn down the heat to 160 and bake for another 10-15 mins
The mix should have stopped jiggling and if you insert a knife to check, it should come out clean when cooked
Serve warm with vanilla ice-cream for an indulgent dessert
