Storage & Shelf Life

These muffins keep really well and can easily be made in advance.

• Room temperature: Store in an airtight container for up to 3 days.
• Fridge: Keeps well for up to 5–6 days. Best if slightly warmed before eating.
• Freezer: Store in a freezer-safe container for up to 3 months. Defrost overnight or warm gently in the oven or microwave.

To maintain freshness, make sure they’re fully cooled before storing, and avoid stacking them, if possible, to prevent sticking.

Recipe Tips

Use ripe bananas: The riper, the better. Look for bananas with brown spots, they’ll be sweeter and mash more easily, giving your muffins a better flavour and texture.

Don’t over-mix the batter: Mix until just combined for best results.

Fresh or frozen blueberries both work: If using frozen blueberries, don’t thaw them first, just fold them into the batter straight from the freezer.

Make your own oat flour: Just whizz rolled oats in a blender until they form a fine flour. It only takes 30 seconds and saves buying separate gluten-free flour blends.

Add toppings before baking: Sprinkle a few extra blueberries and/or a pinch of oats on top of each muffin before baking for a nice finish.

Let them cool properly: It’s tempting to eat straight away but allow them to cool first for the best texture.

Ingredients

 

• 2 cups rolled oats 1 cup blended into flour (160g)
• 2 medium bananas
• ½ cup unsweetened almond milk (125ml)
• 3 tbsp maple syrup
• 3 tbsp lemon juice plus zest of half a lemon
• 1 cup blueberries (150g)
• 3 tbsp olive oil

Instructions

 

• Preheat the oven to 160C or 320F.
• Take half the oats and blend into flour. Add this to a mixing bowl with all the other ingredients.
• Gently mixed everything together until all the ingredients are combined but the blueberries are still intact. Spoon the mixture in cupcake cases.
• Bake for 25-30 minutes until just golden brown. Allow to cool.

Notes

• If you are using ready-made oat flour, only use about 3/4 of a cup. 
• I used fresh fruit, but you can also swap for frozen.
• If you would like them even less sweet, swap the maple syrup for more almond milk.
• Leave to cook before removing from the paper cupcake cases.
