- Spread the batter in an ungreased 9 x 13 inch (23 x 33 cm) pan.
- Sprinkle the semi-sweet chocolate chips evenly over the batter.
- Bake at 350°F (175°C) for 5 minutes.

- Return to the oven and bake for an additional 30 minutes.
- Cool completely in the pan on a wire rack.

Tips & Substitutions
For a creamier texture, try using creamy peanut butter instead of chunky. You can also substitute the butter with coconut oil for a dairy-free version. If you don't have self-rising flour, mix all-purpose flour with 1 1/2 teaspoons baking powder and 1/2 teaspoon salt. For a twist, add crushed nuts or dried fruit to the batter.
Serving Suggestions
These bars are delightful on their own, but pair beautifully with a scoop of vanilla ice cream for an indulgent dessert. They can also be served alongside a fruit salad or a cup of coffee for a satisfying treat. Try them with a drizzle of chocolate sauce or a sprinkle of sea salt for added flavor.

Frequently Asked Questions
Can I use natural peanut butter instead of chunky?
Yes, natural peanut butter can be used, but it may alter the texture slightly. Natural peanut butter tends to be less creamy and can change the moisture content, so you might want to adjust the amount of butter or add a bit more sugar to balance it out.
How do I know when the bars are done baking?
The bars are done when they are set in the center and slightly golden around the edges. A toothpick inserted in the middle should come out mostly clean, with a few moist crumbs. Remember that they will continue to set as they cool.
Can I freeze these bars for later?
Absolutely! To freeze, wrap the bars individually in plastic wrap and then place them in a freezer-safe bag or container. They can be stored in the freezer for up to 3 months. Thaw them in the refrigerator before serving or microwave them for a quick snack.
