I love cookies (who doesn't?), and I always get excited about the thought of a healthy cookie. This one ticks all the boxes for me: it's thick and chewy, filling, rich in goodness like fiber and vitamins, and is totally acceptable to eat for breakfast.

🥘 Ingredients

These peanut butter oatmeal cookies only require 3 ingredients: peanut butter, ripe bananas, and rolled oats.

You can also add extra add-ins as you wish, like chocolate chips or raisins.

🔪 Instructions

Preheat the oven to 185°C/175°C fan oven/365°F.

Mash the bananas in a bowl until smooth.

Add rolled oats and peanut butter, and stir to combine all the ingredients. Add any add-ins if you wish.

Use a fork or spoon to spread the cookie dough into cookies on a baking sheet covered baking tray. The cookies will not change shape when they cook, so shape them the way you want them to turn out.

Bake the cookies for about 15-20 minutes, or until they are golden brown. The cookies will still be soft when removed from the oven.

Move the cookies from the baking tray to a cooling rack. Allow them to cool down completely, which will also help the cookies crisp up.

💡 TIP! Make a big batch and freeze the cookies down to quick and easy future treats, snacks or sweet breakfasts.

💭 Top tips

Here is how you can get these healthy cookies perfect:

• Use ripe bananas, ideally they should be covered with brown spots. Unripe bananas will not taste as good, and can be hard to mash properly.
• Add any add-ins you like. Try adding roughly chopped peanuts, chocolate chips, raisins, blueberries, chocolate spread or coconut flakes.
• This recipe contains no sugar, as the ripe bananas add enough sweetness. If you wish, you can add some brown sugar or honey for extra sweetening.

🍲 Leftovers

Leftover cookies can be stored in an airtight container for up to a few days. They can also be frozen for up to 3 months.

Peanut butter banana breakfast cookies are an excellent make ahead breakfast. Simply freeze them down individually, and thaw them as needed.
