Blueberry and Custard Slice for Babies

Blueberry and Custard Slice Recipe Recipe by Starting Solids Australia

This is a really easy one tray recipe, where you literally mix all of the ingredients in the same dish you bake it in- what a win with less washing up. We love this recipe because it is full of eggs and yogurt so it is packed full of protein, important fats. It also contains vitamins and minerals like choline, vitamin D, calcium and B12 to name a few. 

This is also a dish that is suitable from 6 months old, just modify the blueberries before baking to ensure they aren’t a choking risk. Great as a brekky recipe you can make ahead of time and keep in the fridge for a few days. 

This dish is not very sweet (and if you use a Greek yogurt can be tart) so if you want to add a little sweetness for older kids or adults drizzle with maple syrup before serving.

Suitable: From 6+ months

Modifications: for little people younger than 12 months we would suggest you mash and stir the blueberries through.

Allergens: wheat, dairy (yogurt) and eggs. Unfortunately, these are both crucial ingredients to the dish and cannot be substituted for alternatives if you have allergies or have not introduced them yet.

    1. Hi Em, You can use any tray you have on hand. The size you use will depend on the ‘thickness’ or height of the slice you get as an end result. I’d go for a small to medium sized tray.

  1. Threw this together last night while I was prepping dinner. So easy and love that I can mix in in the baking dish so less mess to clean up after. Gave to bub this morning with his breakfast and he demolished it. ((as a bonus me and my husband enjoyed it too!) Will definitely be making it again. Might try out with raspberries next.
