Preheat oven to 350°F (175°C).
In a large bowl, combine flour, sugar, and peanut butter.
Add eggs, baking soda, and vanilla extract; mix until smooth dough forms. If using, add melted butter or oil for extra moisture.
Fold in any optional mix-ins like chocolate chips or nuts.
Spread dough evenly into a greased 9×13-inch baking pan, pressing firmly.
Bake for 20–25 minutes until edges are golden and center is set.
Allow bars to cool completely in the pan before slicing into 24 squares.
Serve as a snack or dessert.

Using natural peanut butter may require extra flour to adjust texture.

For gluten-free, substitute all-purpose flour with a gluten-free blend.

Drizzle melted chocolate or sprinkle sea salt on top for extra flavor.

Store bars at room temperature in an airtight container for up to 5 days or refrigerate for up to 1 week.

Freeze tightly wrapped for up to 3 months; thaw at room temperature before serving.
