Ingredients

3 cups quick-cook oats

¼ teaspoon salt

½ cup butter

2 cups sugar

½ cup milk

1 cup peanut butter

2 teaspoons vanilla extract

Instructions

Prepare dry ingredients: In a large bowl, combine oats and salt. Set aside.

Make the syrup: In a small saucepan over medium-high heat, whisk together butter, sugar, and milk.

Boil: Bring to a rolling boil and cook for exactly 1 minute, then remove from heat.

Add flavor: Whisk in peanut butter and vanilla until smooth and combined.

Combine: Pour the peanut butter mixture over the oats and stir until evenly coated.

Form cookies: Line a baking sheet with wax paper. Drop spoonfuls (or use a cookie scoop) of the mixture onto the sheet.

Cool and set: Allow cookies to cool completely at room temperature before transferring to the refrigerator for storage.

Notes

Boiling tip: Start timing the 1-minute boil only once the mixture reaches a rolling boil (lots of bubbles across the surface).

Texture fix:

If cookies are too hard, the mixture boiled too long.

If cookies are too soft, it didn’t boil long enough.

Cooling tip: Let cookies cool on the counter before refrigerating — chilling too early can make them gooey.

Storage: Store in an airtight container in the fridge for up to 1 week.
