These peanut butter cookies do exactly that.

Why Are These Peanut Butter Cookies So Easy to Make?

This is a genuine one-bowl recipe that comes together in about five minutes of prep time. You beat the wet ingredients together, stir in the dry ones, roll and bake. There is no chilling the dough overnight, no fancy equipment beyond an electric mixer and no complicated technique to master.

The payoff is a batch of 18 cookies, each sitting at around 174 kcal, with a satisfying texture that comes from the combination of peanut butter, butter and rolled oats. They are also a solid choice for anyone chasing high protein cookies as a snack, given the protein hit from the peanut butter and oats working together.

What Ingredients Make the Best Peanut Butter Cookies?

Every ingredient in this recipe has a job to do. Here is a quick breakdown so you understand what is happening in the bowl:

• Peanut butter: Smooth or crunchy both work beautifully. Smooth gives a more even texture while crunchy adds little pops of roasted nut throughout.
• Rolled oats: These add fibre, a subtle chew and a slightly rustic texture that sets these apart from a plain biscuit. Instant oats can be substituted if that is what you have on hand.
• Brown and granulated sugar: Using both is the trick. Brown sugar brings moisture and that deep caramel flavour while granulated sugar helps the edges crisp up. You can use just one if needed.
• Cinnamon and vanilla: This duo is what lifts the whole cookie from good to genuinely memorable. The warmth of cinnamon pairs perfectly with the nuttiness of the peanut butter.
• Butter, plain flour, egg, baking powder and salt: Your classic pantry staples doing all the structural work.

How to Make Peanut Butter Cookies: Step-by-Step

Ingredients

• 125 g (½ cup) butter, softened
• 125 g (½ cup) smooth peanut butter
• 110 g (½ cup) brown sugar
• 110 g (½ cup) granulated sugar
• 1 egg, lightly beaten
• 1 teaspoon vanilla extract
• ¼ teaspoon ground cinnamon
• 155 g (1¼ cups) plain flour
• ½ teaspoon baking powder
• 45 g (½ cup) rolled oats
• Pinch of salt

Method

1. Preheat your oven to 180°C. Line a large baking tray with baking paper.
2. Add the butter, peanut butter, both sugars, egg, vanilla and cinnamon to the bowl of an electric mixer. Beat until light and fluffy, about two minutes.
3. Add the plain flour, baking powder, rolled oats and salt to the bowl. Stir with a silicone spoon until a soft dough forms.
4. Roll the dough into balls roughly 2.5 cm in diameter and place them on the prepared tray about 4 to 5 cm apart.
5. Press each ball down gently with a fork in a criss-cross pattern to flatten slightly.
6. Bake for 14 minutes until golden. Remove from the oven and allow the cookies to cool completely on the tray before transferring to a container.

Finishing tip: For a chocolate-peanut twist inspired by the classic Australian scorched peanut bar, dip cooled cookies halfway into melted dark chocolate and leave to set on a wire rack. It is a simple finish that looks seriously impressive on a plate.

How Do You Store These Cookies and What Goes Well With Them?

Store your peanut butter cookies in an airtight container at room temperature for up to three days. Pop them in the fridge and they will keep for up to two weeks. If you want to bake in batches, the raw dough freezes well wrapped tightly in cling wrap inside a freezer-safe bag for up to one month. Thaw in the fridge overnight and bake straight from cold.

These cookies are wonderful with a cold glass of milk or a strong cup of coffee. Warmed briefly in the microwave and served with a scoop of vanilla ice cream, they make a fuss-free dessert that feels anything but. They are also a great addition to a Breakfast Brunch Masterclass spread, baked ahead and served alongside other morning treats.
