Ingredients for Peanut Butter Celebration Cookies
- All-Purpose Flour – To make them gluten-free, use a 1:1 gluten-free baking flour
- Baking Soda – Key for light, fluffy cookies (don’t substitute baking powder)
- Salt – Enhances and balances the sweetness
- Granulated Sugar
- Brown Sugar – Light or dark both work
- Unsalted Butter – Salted butter can overpower the sweetness
- Peanut Butter – “Choosing the right peanut butter matters—this is why I recommend creamy peanut butter in my classic peanut butter cookie recipe.”

How to Make Peanut Butter Celebration Cookies
- Preheat oven to 375°F. Grease or line baking sheets.
- In a bowl, whisk together flour, baking soda, and salt. Set aside.
- Cream butter, granulated sugar, and brown sugar until light and fluffy (2–3 minutes).
- Add egg, milk, and vanilla. Mix until fully combined.
- Add dry ingredients and mix on low just until a dough forms.
- Gently fold in sprinkles—do not overmix.
- Scoop dough into balls and place on baking sheet. Lightly press each ball down.
- Bake for 9–11 minutes, removing cookies when centers look slightly underbaked.
- Cool on baking sheet briefly, then transfer to a wire rack.
Tip: Skip the traditional fork criss-cross. Leaving the dough thicker helps these cookies stay soft and fluffy.
Why Did My Peanut Butter Cookies Turn Out Hard?
The most common reason peanut butter cookies turn out hard is overbaking. Cookies continue to firm up as they cool, so pulling them from the oven early is key. Another issue is not creaming the butter and sugars long enough, which prevents proper aeration.
