Ingredients

- Creamy peanut butter – 1 cup
- Powdered sugar – 2 cups
- Graham cracker crumbs – 2 cups
- Semi-sweet chocolate chips – 1 ½ cups
Step-by-Step Instructions
Make the Peanut Butter Base
In a large mixing bowl, stir together the melted butter and creamy peanut butter until smooth and fully blended. This combination forms the rich, velvety foundation for your bars.
Add the Dry Ingredients
Mix in the powdered sugar and graham cracker crumbs. Stir until the mixture becomes thick and cohesive, resembling a soft dough that can easily be pressed into shape.
Press into the Pan
Transfer the peanut butter mixture into a 9×13-inch baking dish. Press it evenly using the back of a spoon or your hands, ensuring the base is compact and level for a neat finish.
Melt the Chocolate
Place the semi-sweet chocolate chips in a microwave-safe bowl. Heat in 30-second intervals, stirring after each session, until the chocolate is silky smooth. Avoid overheating, as chocolate can burn quickly.
Create the Chocolate Topping
Pour the melted chocolate over the peanut butter layer. Use a spatula to spread it evenly across the surface, covering every edge.
Chill to Set
Refrigerate the bars for at least 2 hours, allowing the chocolate to firm up and the layers to hold together perfectly.
Slice and Serve
Once set, cut into squares of your desired size. Serve chilled or at room temperature, depending on your preference.
Tips for Perfect Peanut Butter Lunch Lady Bars
- Choose the right peanut butter – Use creamy peanut butter for a smooth texture. Avoid natural peanut butter with separated oils, as it can affect consistency.
- Graham cracker texture matters – Finer crumbs will create a denser, smoother base, while slightly coarser crumbs add more bite.
- Cut clean slices – Warm your knife under hot water, wipe it dry, and slice through the chilled bars for neat, bakery-style edges.
- Add a twist – Sprinkle sea salt over the chocolate layer before chilling for a sweet-salty flavor boost.
- Store smart – Keep them in the fridge for freshness, or freeze for up to a month.

Can I replace graham crackers with something else?
You can use digestive biscuits or vanilla wafer crumbs for a similar texture and flavor.
What’s the best way to melt chocolate without burning it?
Use short microwave intervals and stir frequently. Alternatively, melt it gently over a double boiler.
Do these bars need to stay refrigerated?
While they can sit out for a short period, refrigeration helps keep them firm and fresh, especially in warmer climates.
