Serving sizes are based on adult portions.

Peanut butter bars: 1 square per adult

Here is a guide for children:

Toddler (age 1-4): ¼ portion (¼ peanut butter square)

Young child (age 5-9): ½ (½ peanut butter square)

Older child (age 10-13): ¾ (¾ peanut butter square)

Teenagers (14+): 1 (1 peanut butter square)

Some children do have bigger appetites than others. You child’s portion may need to be changed to fit their typical diet if you think the recommended serving sizes are too large or small. We would advise speaking with your dietitian prior to increasing the serving size if your child has struggled to manage potassium or phosphate.

Oats, cornflakes, sugar and jam are the main sources of carbohydrate, and the value has been provided for those trained in insulin adjustment.

This recipe is very low in potassium and phosphate, but does contain some phosphate, mainly from the oats and peanut butter, so if you have been prescribed a phosphate binder, take as directed.

Many peanut butter brands are unsalted, but some do contain added salt, so it's best to check the ingredients list and choose one without added salt where possible.

This recipe has been kept as low in cost as possible, and even unsalted peanut butters are available in budget supermarkets.

Replace butter with vegan alternative and ensure cornflakes are vegan.

Use gluten-free oats and cornflakes.
