Preheat the oven to fan 170 and line a 8 inch circular sponge cake tin with parchment paper.
Add all the wet ingredients to a large bowl and whisk well.
Tip in the oat flour, baking powder and add a pinch of salt. Stir well until combined.
Pour the sponge mix into the baking tin. Place in the oven for 35-40 minutes until golden.
Allow to cool before spreading an even layer of mixed berry chia jam and a sprinkling of desiccated coconut. (The recipe for my homemade chia jam is in the notes)
Notes
Healthy Chia Mixed Berry JamIngredients• 300g mixed berries (fresh or frozen – strawberries, raspberries, blueberries work well)• 2 tbsp chia seeds• 2 tbsp honey or maple syrup• 1 tsp lemon juiceMethod1. Add the berries to a saucepan over a medium heat.2. Cook for 5 minutes, stirring occasionally, until the berries soften and release their juices.3. Lightly mash the berries with a fork or potato masher (leave some texture if you like).4. Remove from the heat and stir in the chia seeds, lemon juice and honey/maple syrup.5. Leave to cool for 10 minutes, stirring once or twice - it will thicken as the chia seeds absorb the liquid.6. Transfer to a clean jar and refrigerate.Top TipsThicker jam? Add another 1 tbsp chia seeds.Smoother texture? Blend briefly before cooling.Storage:Keeps in the fridge for up to 7 days.This lemon cake is equally delicious without the jam topping. If you would prefer, you could make a honey and lemon glaze by adding 2 tbsp of honey to a bowl along with 2 tsp of lemon juice. Mix well before adding to the top of the cake instead of the chia jam.
