Instructions for the caramelised banana

• Place butter and sugar into a small saucepan and heat until mixture melts.
• Add banana, and place over a medium heat for approximately 15 minutes, or until bananas are well coated in a thick caramel. If your mixture is too runny, simply discard the excess liquid before using.
• Place banana pieces onto baking paper and place in the fridge to cool. 

Ingredients for the muffins/cake

• Grease and line a muffin tin (the size is up to you!) or a large cake tin and preheat oven to approximately 190 degrees Celsius.
• Combine milk and vinegar into a mediuma sized jug and set aside for 15 minutes.
• Using a hand held mixer, beat aquafaba until soft peaks form. Set aside. 
• Add oil to milk mixture.
• Sift flour, powder, sugar and salt into a large bowl and make a well in the centre.
• Add milk mixture and mix until just combined. Remove banana from fridge.
• For muffins: evenly distribute half the batter into prepared tin, the place a spoonful of banana on top pf each one. Place remaining batter over the banana.
• For a cake: pour half the batter into prepared tin, evenly spread banana on top, then cover with remaining batter.
• Lightly tap tin against your kitchen bench to remove air bubbles, and place in the oven to cook for between 20 and 40 minutes for muffins or 1 hour for a cake, depending on how big your tin is. Your muffins/cake will be ready when they spring back when pressed and have started to brown.
• Remove muffins/cake from the oven and set aside to cool completely.
