Delicious soft oat bars flavoured with peanut butter and banana. Made with just six simple ingredients and perfect for a batch cook healthy breakfast

If mornings are rushed, these Peanut Butter & Banana Breakfast Bars are ideal to prepare at the weekend and enjoy all week. They use only six simple ingredients and are naturally sweetened with banana, making them a healthier alternative to many shop-bought breakfast bars or muffins.
Store the bars in the fridge for up to two days and reheat briefly in the microwave if you prefer them warm. They also freeze well — freeze individual squares and defrost overnight in the fridge or at room temperature for a couple of hours. Freezing instructions are provided in the notes below.

Each square works out to approximately 175 calories without toppings. They’re delicious plain or topped with an extra smear of peanut butter and banana slices, and pair nicely with Greek yogurt and berries for a more substantial breakfast.

Notes
Store the bars in the fridge for up to 2 days. Reheat briefly in the microwave or enjoy cold. For freezing, place individual squares in an airtight container or freezer bag; defrost overnight in the fridge or at room temperature for a couple of hours.
Use 100% peanut butter with no added sugar for the best flavour and nutrition.
Nutrition figures are approximate and refer to the bars alone, without any toppings. Calculate exact values yourself if you require precision.
