Line a loaf tin with baking paper or parchment. Leave some over the edges, you will use this to pull the cake out of the tin later.
Chop the rhubarb stems into 1 cm slices and sprinkle with 1 teaspoon of the sugar.
100 g chopped rhubarb
Roughly mash the bananas in a large mixing bowl
220 g super ripe bananas
Add the sugar, oil, vanilla, and plant milk, and give it a good stir. You want the sugar to start to dissolve.
60 ml vegetable oil, 60 ml plant milk, 100 g light brown sugar, 2 teaspoon pure vanilla extract
Sift in the flour, baking powder, salt and mix.
240 g flour, 1 teaspoon baking powder, ½ teaspoon salt
Fold in the rhubarb.
Transfer the banana and rhubarb cake mix to the lined tin.
Add extra bits of sliced banana or rhubarb if desired on top & pop in the oven.
Bake for about 35 mins. Then test the cake with a skewer. If it comes out clean, then the cake is done. If not, put it back in your oven for another 5-10 mins.
Use the paper you cleverly left hanging over the edges to remove it from the tin, then let the cake cool.
This banana bread will keep for around a week in an airtight container. It also freezes well!
Notes
Equipment
I always bake my banana loaf cakes in a 28cm/11" x 10cm/4" tin, which I line with greaseproof paper. A smaller tin will take longer to bake in the oven, so be sure to take that into account when baking. If using a smaller loaf tin, cover the top with foil in the last stages of baking to prevent the top from catching and burning. .
Substitutions & Variations
This recipe is so easy and always turns out perfectly, even in my old and slightly erratic oven. Here are some variations you can try.
Gluten-Free- choose your favourite gluten-free flour to make this a gluten free banana bread. I find that sometimes you will need a little extra plant milk with gluten-free baking.
Muffins - this recipe makes excellent Rhubarb Banana Muffins. Mix in exactly the same way, then bake in a lined muffin tin at 190C/375F for 25 minutes or until cooked. You can also top it with streusel or coconut to be extra fancy.
Other Fruits -substitute the rhubarb for strawberries, raspberries or apples.
