I found this recipe on a box of Huggies and my DS loves them. They are also sugar free which is a bonus.

Banana and pear muffin (sugar Free)
Ingredients:
1/2 cup of organic self-raising flour (I use wholemeal)
1 egg
1 ripe banana
1 pear
1/2 cup olive oil (I use slightly less)
teaspoon of spice
1 tablespoon of milk (cow or an alternative is fine)
Method:
1. Peel and finely chop the pear.
2. On a plate, mash the banana with a fork.
3. Place the oil and egg in a bowl and whisk until blended.
4. Add the spice and pear to the flour.
5. Add the oil mixture and bananas alternatively to the flour and gently blend.
6. Add the milk if required.
7. Spoon mixture into greased muffin tray or muffin patty cups.
8. Bake for 15/20 minutes or until cooked.
