Low FODMAP banana and cinnamon muffins

4 ripe bananas - mashed
1/3 cup vegetable oil or sunflower oil
3/4 cup light brown sugar
1 egg
1 teaspoon vanilla extract
1 and 1/2 teaspoon baking soda
2 teaspoon ground cinnamon
​juice of 1/2 a lemon
1 & 1/2 cups rice flour
a pinch of salt

To make my low FODMAP, gluten free banana and cinnamon muffins start by preheating your oven to 180C (355F)
Mash the bananas in a mixing bowl, then add the oil, sugar, egg and vanilla to the mashed banana. Mix together thoroughly with a spoon. 

Put the baking soda salt & rice flour into the mixing bowl containing your banana/oil mix. Mix all ingredients together until combined. Finally add the lemon juice and mix through. 

Spoon the batter into muffin trays and put in the oven, they should take about 20 minutes to cook.
