Put the butter in a 1-litre baking dish and microwave on High for 30 secs-1 min until melted. Add 1½ bananas, mash into the melted butter, then add the sugar, flour, cinnamon, eggs and milk. Mix together well.
Slice the remaining banana over the top, then return to the microwave and cook on High for 8 mins until cooked through and risen. Serve warm, dusted with icing sugar, if you like, with a drizzle of toffee sauce and a scoop of ice cream.
140g butter, softened, plus extra for the tin
140g caster sugar
2 large eggs, beaten
140g self-raising flour
1 tsp baking powder
2 very ripe bananas, mashed
50g icing sugar
Heat oven to 180C/160C fan/gas 4. Butter a 2lb loaf tin and line the base and sides with baking parchment.
Cream the butter and sugar until light and fluffy, then slowly add the eggs with a little flour. Fold in the remaining flour, baking powder and bananas. Pour into the tin and bake for about 30 mins until a skewer comes out clean. Cool in the tin for 10 mins, then remove to a wire rack.
Mix the icing sugar with 2-3 tsp water to make a runny icing. Drizzle the icing across the top of the cake and decorate with banana chips.
Chocolate Baked Bananas
4 ripe bananas
2 x 32g bag chocolate buttons
vanilla ice cream, to serve
Heat oven to 200C/180C fan/gas 6 (or a BBQ). Make a slit through the skin of the bananas along one side – making sure you don’t cut all the way through to the other side. Poke in the chocolate buttons along the cut. Put each banana onto a sheet of foil and crimp the edges together to seal into a parcel. Transfer to a baking sheet and cook for 25 mins until the bananas have turned black (or pop straight into the BBQ embers for 15 mins).
Serve with a scoop of ice cream and any melted chocolate that has escaped!
