Step-by-Step Instructions To Make Lunch Lady Bars
- Step 1: Start by crushing your graham crackers in a food processor until they become a fine powder.
- Step 2: In a microwave-safe bowl, melt the butter and peanut butter in 30-second intervals, stirring until smooth.
- Step 3: Pour the mixture into a large bowl. Add the graham cracker crumbs, powdered sugar, and salt. Mix until well combined.
- Step 4: Line a 9×13-inch baking pan with parchment paper. Press the peanut butter mixture evenly into the pan. Pop it in the fridge for about 20 minutes.
- Step 5: While the base chills, melt your chocolate chips with the remaining peanut butter in the microwave—again, in 30-second bursts, stirring between each.
- Step 6: Spread the melted chocolate evenly over the chilled base. Chill for at least 1 hour before slicing.
Helpful Tips for the Best Lunch Lady Bars
- Use softened butter, not melted. Creaming softened butter with the sugars gives the bars their chewy, bakery-style texture.
- Don’t overmix the batter. Once you add the flour, mix just until combined to keep the bars soft and tender.
- Line your pan with parchment paper. It makes removal (and cleanup!) a breeze—plus you’ll get perfect edges every time.
- Cool completely before frosting. The frosting will melt and soak in if the bars are warm, so let them cool fully for that classic fudgy layer on top.
- Cut with a warm knife. For clean, smooth squares, dip your knife in warm water and wipe between slices.
How to Store
These bars should be stored in an airtight container in the refrigerator. They’ll keep well for up to 1 week (if they last that long!). You can also freeze lunch lady bars—just wrap each piece in parchment paper and place in a freezer-safe bag for up to 2 months.
Variations
- Add crushed pretzels to the base for a salty crunch.
- Use almond butter instead of peanut butter for a twist.
- Top with mini chocolate chips or chopped peanuts before chilling for some extra texture.
