Sweet And Nostalgic Peanut Butter Bars!
Even though school cafeterias don’t serve these lunch lady bars anymore because of allergy concerns, they were a total staple of my childhood. I can still remember them clearly! As a peanut butter and chocolate lover, these were always a reliable, and to this day, they still feel really nostalgic.
The oaty brown sugar base, that creamy peanut butter layer, and the soft chocolate frosting on top…I mean, come on. They’re so good.
I also love making these when I need something straightforward to share or bring to an event since they make a big batch and are always a crowd-pleaser.
Lunch Lady Bars Ingredients
| Ingredient | Let’s Chat About It |
|---|---|
| Butter & Brown Sugar | Use room temp butter so it creams smoothly with the sugar and gives the bars a chewy, soft texture. |
| Eggs & Vanilla | Bring eggs to room temp for better mixing and a more even batter. |
| Oats & Flour | Stick with old-fashioned oats for the right texture. Quick oats will make the bars dry since they absorb more liquid. |
| Peanut Butter | Use creamy, no-stir peanut butter for the best texture and straightforward spreading over these Lunch Lady Bars. |
| Frosting Ingredients (butter, milk, cocoa powder, powdered sugar) | Use real butter and Dutch-process cocoa for the best frosting flavor and texture. |
Let’s Talk Pan Size
What Pan To Use
These lunch lady bars require a specific pan to turn out right. Using a different size will change the thickness and texture.
Use a 17 x 12.25-inch jelly roll pan or a 13 x 18-inch sheet pan. (These photos are using the 13 x 18-inch pan)
How To Make Lunch Lady Bars
- Prep: Heat oven, line or grease a jelly roll pan, and keep nearby.
- Cream: Beat butter and sugar, then mix in remaining ingredients until combined.
- Bake: Press dough evenly into pan and bake until set but still soft.
- Peanut butter layer: Warm, drizzle, and spread peanut butter; let set.
- Frost & cut: Beat frosting until smooth, spread over cooled bars, then slice with a hot, sharp knife.
the cook’s Notes
My Number One Tip!
Use fresh ingredients: Fresh, super soft brown sugar and active leavening give these lunch lady bars a better and softer texture.
Variations
Turn these into Lunch Lady Peanut Butter Brownies by starting with brownies, adding a peanut butter layer, and finishing with chocolate buttercream.
Storage
Lunch Lady Bars store well in an airtight container at room temp. They’re softest within 2 to 3 days and last up to 5 days.
Freeze by wrapping bars individually and storing in a bag or container. Freeze up to 3 months and thaw overnight in the fridge.
