How to Make 4-Ingredient Oat Flour Peanut Butter Cookies

PIN IT

Step 1: Preheat & Prep

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. Your kitchen is about to smell amazing — promise.

Step 2: Mix the Dough

In a medium bowl, stir together the oat flour and baking soda. Add peanut butter and maple syrup, then mix until a thick, soft dough forms. It should feel slightly sticky but scoopable.

This is where I always sneak a taste — quality control, obviously

Step 3: Shape

Scoop tablespoon-sized balls onto the baking sheet. Gently flatten with a fork or the back of a spoon. These won’t spread much on their own.

Step 4: Bake

Bake for 10–12 minutes, until the edges look lightly golden and the centers are just set.

Step 5: Cool (The Hard Part)

Let cookies cool on the pan for 5 minutes. They firm up as they rest — and yes, patience is rewarded here.

What to Serve with These Cookies

• A cold glass of almond or oat milk
• Hot coffee or chai tea
• Crumbled over dairy-free ice cream
• Packed into lunchboxes or road-trip snack bags

They’re especially lovely with a cozy mug of coffee on a slow afternoon.

Tips for Making It Perfect

• Use natural peanut butter with no added sugar or oils
• Don’t overbake — they should look slightly underdone
• Let them cool before moving (they’re delicate when hot)
• If dough is too dry, add 1–2 teaspoons maple syrup

Storage Instructions

• Room Temperature: Store in an airtight container for up to 4 days
• Refrigerator: Keeps well up to 7 days
• Freezer: Freeze baked cookies for up to 2 months
• Reheat: 5–7 seconds in the microwave brings them right back to life
