We have a thing for cookies in my household.
Last minute need to make a dessert with friends over? Chocolate chip cookies. Stand over the oven and have a warm one.
Need to bring something to a potluck or work event? Thumbprint cookies with jam.
Want to win over my significant other? Peanut butter cookies. With cross-hatched fork marks.
While I love making peanut butter cookies from scratch, I never understand the need for all the butter and sugar. Peanut butter is the most delicious ingredient ever – can’t we let it star as the main ingredient?
After toying a few proportions, and trying to tease out the most peanut-buttery taste from these cookies, I ended up with this gem: a 5 ingredient recipe with a hefty base of pure peanut butter. I won’t lie that I can demolish a batch of these in 2 days (I couldn’t help but bite into one below).
The cookies are small on purpose, friends – you should have a handful.
- ½ cup unsalted peanut butter (see note)
- ¼ cup old fashioned oats
- 3 tablespoons granulated sugar
- 1 large egg
- ⅛ of a teaspoon salt
- Preheat the oven to 350 degrees.
- In a bowl, mix together peanut butter, oats, sugar, egg and salt. Stir together vigorously until everything is incorporated.
- Line a baking sheet with parchment paper or a silicone baking mat. Using your hands, form 1 tablespoon-sized balls and flatten them a bit onto the baking sheet. Use a fork to make cross-hatches in the tops of the cookies.
- Bake the cookies for 8-9 minutes, until the bottoms are lightly golden.
- Allow them to cool before storing in an airtight container for up to 5 days.
