Lunch Lady Peanut Butter Bars: From Prep to Plate

Now, let’s get to the good part: making your Lunch Lady Peanut Butter Bars! Follow these simple steps to create a batch of delicious bars.

Step 1: Preheat your oven

Begin by preheating your oven to 350°F (175°C). This ensures that your bars bake evenly and come out perfectly golden.

Step 2: Prepare your baking pan

Grease a 9×13-inch baking pan with cooking spray or butter, and line it with parchment paper for easy removal.

Step 3: Cream the butter and sugars

In a large mixing bowl, combine the softened unsalted butter, granulated sugar, and brown sugar. Using an electric mixer, cream the mixture until it becomes light and fluffy. This should take about 2-3 minutes.

Step 4: Add the eggs and vanilla

Add the eggs, one at a time, mixing well after each addition. Then, stir in the vanilla extract, ensuring everything is well incorporated.

Step 5: Mix in the peanut butter

Next, add the peanut butter to the mixture and blend until smooth. The mixture will be creamy and rich at this stage.

Step 6: Combine dry ingredients

In a separate bowl, whisk together the old-fashioned oats, flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, mixing just until combined. Be careful not to overmix.

Step 7: Pour the batter into the pan

Spread the batter evenly into the prepared baking pan. Use a rubber spatula to smooth the top, ensuring an even surface for baking.

Step 8: Bake

Bake in the preheated oven for 25-30 minutes, or until the edges are lightly golden and a toothpick inserted into the center comes out clean. Allow the bars to cool in the pan for about 10 minutes before transferring them to a cooling rack.

Step 9: Prepare the frosting

While the bars are cooling, prepare the creamy peanut butter frosting. In a mixing bowl, combine the creamy peanut butter, softened butter, and cocoa powder. Mix until smooth.

Step 10: Add milk and powdered sugar

Gradually add the powdered sugar, vanilla extract, and enough milk to achieve your desired frosting consistency. Mix until smooth and creamy.

Step 11: Frost the bars

Once the bars have cooled completely, spread the peanut butter frosting evenly over the top. Use a spatula to create an even layer.

Step 12: Cut and serve

Let the frosting set for a few minutes, then cut the bars into squares. Serve them at room temperature or chilled for a refreshing treat.

Seasonal Twists

To keep things interesting, consider these seasonal variations of your Lunch Lady Peanut Butter Bars:

• Chocolate Chip Peanut Butter Bars – Add a cup of chocolate chips to the batter for extra indulgence.
• Crunchy Peanut Butter Bars – Use crunchy peanut butter instead of creamy for added texture.
• Banana Peanut Butter Bars – Incorporate mashed ripe bananas into the batter for a fruity twist.
• Nutty Peanut Butter Bars – Mix in chopped nuts like almonds or pecans for a delightful crunch.

Chef’s Rationale

Baking is an art, and creating Lunch Lady Peanut Butter Bars is an exercise in balance. The combination of sugars creates a sweet and chewy base, while the oats add texture. The creamy peanut butter frosting elevates these bars, ensuring every bite is a harmonious blend of flavors. Using high-quality ingredients, like fresh peanut butter and real butter, enhances the overall taste and makes a noticeable difference in your final product.

Freezer-Friendly Notes

If you find yourself with leftovers (although that’s unlikely!), you can easily freeze these bars for a later treat.

• Allow the bars to cool completely.
• Wrap them tightly in plastic wrap, then place them in an airtight container or freezer bag.
• They can be frozen for up to 3 months.
• When ready to enjoy, simply thaw at room temperature or in the refrigerator.

Quick Questions

Can I use natural peanut butter instead of creamy peanut butter?

Yes, you can use natural peanut butter, but be aware that it may alter the texture slightly. Natural peanut butter can be more oily, so make sure to stir it well before using.

How should I store leftover bars?

Store leftover Lunch Lady Peanut Butter Bars in an airtight container at room temperature for up to a week, or refrigerate for longer freshness.

Can I make these bars gluten-free?

Absolutely! Substitute regular flour with a gluten-free flour blend to make these bars gluten-free.

What can I use if I don’t have brown sugar?

You can substitute brown sugar with an equal amount of white sugar and add a tablespoon of molasses to replicate the flavor and moisture of brown sugar.
