Ingredients

How to make this banana rhubarb raspberry slice 

This banana bread begins with blending the wet ingredients, including mashed bananas, eggs, butter, vanilla extract and milk, into a smooth mixture. Dry ingredients such as wholemeal spelt flour, bicarb, and cinnamon are folded into the wet mix, creating a light batter. The batter is poured into a prepared slice tin and topped with thin slices of rhubarb and raspberries. Bake until the centre is set and golden brown.

Serving suggestions and how to store

Serve this slice warm as a comforting snack or dessert with a dollop of Greek yogurt or coconut yogurt. It also pairs well with a hot cup of tea. Store leftovers in an airtight container in the fridge for up to a week or freeze individual portions for convenience.

Vary banana rhubarb raspberry slice to suit 

For a dairy-free version, swap butter with coconut oil or macadamia nut oil. Use your preferred gluten-free flour blend to make it gluten-free. To replace eggs, try chia eggs for a plant-based alternative. Feel free to experiment with different seasonal fruits like blueberries, apples, or pears for variety. For a protein boost, mix in nuts or seeds, or sprinkle them on top before baking.

Tip

Ensure the bananas are very ripe, as their natural sweetness is key to the flavour of this slice, with minimal added sugar used.
