Why You’ll Love This Recipe

These peanut butter cookie dough bars come together in just one bowl with no mixing required. The combination of creamy peanut butter, brown sugar, and vanilla creates that authentic cookie dough flavor we all crave.

Unlike traditional cookie dough, these bars are completely safe to eat since there are no raw eggs. They’re also naturally gluten-free when made with oat flour or almond flour.

The bars firm up beautifully in the refrigerator, making them easy to slice and serve. They keep for up to a week stored covered, though they rarely last that long!

Ingredients You’ll Need

Creamy peanut butter – provides the base flavor and binds everything together
Brown sugar – adds sweetness and that classic cookie dough taste
Vanilla extract – enhances the overall flavor profile
All-purpose flour – gives structure and that authentic cookie dough texture
Mini chocolate chips – optional but highly recommended for extra sweetness
Salt – balances the sweetness and enhances the peanut butter flavor

For best results, use room temperature peanut butter for easier mixing. Natural peanut butter works too, just make sure it’s well-stirred before measuring.

How to Make Them

Start by lining an 8×8-inch baking pan with parchment paper for easy removal. In a large mixing bowl, combine the peanut butter and brown sugar until smooth and creamy.

Add the vanilla extract and salt, mixing until well combined. Gradually fold in the flour until a thick dough forms – it should hold together when pressed.

Fold in the chocolate chips if using, then press the mixture firmly into your prepared pan. Refrigerate for at least 2 hours before cutting into bars.

Storage Tips

These peanut butter cookie dough bars store beautifully in the refrigerator for up to one week. Keep them covered with plastic wrap or in an airtight container to maintain freshness.

For longer storage, wrap individual bars in plastic wrap and freeze for up to 3 months. They thaw quickly at room temperature in about 15 minutes.

Cut the bars while they’re cold for the cleanest slices. A sharp knife wiped clean between cuts gives you perfect squares every time.
