This recipe proves that good cakes don’t have to be baked the traditional way.

And for those who love a little extra indulgence, the optional lemon glaze brings a tangy, sweet layer of flavor that pairs perfectly with the richness of bananas.

Children will love it, guests will ask for seconds, and you’ll enjoy how easy it is to prepare. This cake is proof that homemade gluten-free desserts don’t need to be complicated or expensive.

Equipment

mixing bowls
mortar & pestle (or grinder)
fork/masher
wide heavy pan with lid
Wooden Spoon
Spatula

Ingredients

2 cups traditional oats
½ cup sugar (or adjust to taste)
1 tsp baking powder
½ tsp bicarbonate of soda
Pinch of salt (⅛ teaspoon)
1 tsp vanilla flavoring
2 eggs
¼ cup vegetable oil
3-4 medium ripe bananas
1 tsp margarine/fat (for greasing)
A little flour (for dusting)

Optional Glaze:

Juice of one large lemon
1 cup icing sugar

Instructions

Roast and crush the oats
Heat your pan on medium heat and roast the oats for 5–7 minutes until lightly browned and crisp. This enhances the flavor and makes crushing easier.
Transfer the oats to a mortar and pestle and crush until fairly smooth but slightly coarse. (You can also grind using a grinder)
Mix the dry ingredients
In a mixing bowl, combine the crushed oats, sugar, baking powder, bicarbonate of soda, and salt.
Mix well and set aside.
Prepare the wet mixture
Mash the ripe bananas until smooth.
Add in eggs, vegetable oil, and vanilla flavoring. Mix until well combined.
Combine wet and dry ingredients
Add the oat mixture into the banana mixture. Stir until you have a smooth batter with no lumps.
Grease and prepare your pan
Grease a wide pan (10–11 inches) with marge and dust lightly with flour.
Pour in the batter and spread evenly.
Cook without an oven
Cover the pan and cook on your gas stove using very low heat as shown below, for about 35–40 minutes.
Insert a skewer to check doneness—it should come out clean.
Flip carefully and cook the other side for another 10 minutes to brown.
Optional lemon glaze
Mix lemon juice with icing sugar to form a smooth glaze.
Spread between two cake layers or drizzle on top.
(You can also work with your preferred frosting.)
