Do you remember eating those sweet, fudgy, frosted brownies as a kid at lunch? Or maybe you had them for an after-school snack with a tall glass of ice-cold milk? I found this recipe in one of my old cookbooks and remember them always being present at any potluck.

My other favorite brownie recipe is this One Bowl Cocoa Brownies. They are thick, rich, and delicious! Or try these readers’ favorite Homemade Chewy Brownies. They are a lot like boxed brownies, only taste better!

Why You Need These Frosted Brownies:

  • Full of old-fashioned deliciousness
  • Super easy to make
  • Perfect served warm or room temperature, plain or with a scoop of ice cream
  • Great for sharing and taking to potlucks
  • Sweet milk chocolate-like flavor
Ingredients: cocoa, flour, sugar, salt, brown sugar, vanilla, butter, eggs, chocolate chips, milk.

A Few Key Ingredients:

COCOA POWDER: Cocoa powder makes brownies so rich and full of chocolate flavor because it isn’t diluted with other ingredients. You can use natural or Dutch processed cocoa powder in this recipe because no leavening is used.

BUTTER: I like to use butter for flavor!
SUGAR: I am using granulated and brown sugar because brown sugar helps keep the brownies soft.

EGGS: Eggs are what add structure and hold brownies together. They also add richness and help create a fudgy texture.

How To Make Frosted Brownies, AKA Lunch Lady Brownies:

STEP 1: Mix the butter and cocoa powder together until smooth. Add eggs and vanilla and whisk until smooth.

STEP 2: Add the flour, sugar, brown sugar, and salt. Whisk together just until combined.

STEP 3: Pour into prepared pan and bake!

FROSTING: In a medium saucepan, bring the butter, milk, and sugar to a boil, stirring constantly. Stir in the chocolate chips until smooth. Pour over brownies.

How Do I Know When These Brownies Are Done?

Lunch lady brownies are a little different than other brownies. When these brownies are done, they will look matte on top and won’t have a shiny crust. There will be tiny bubbles on top, and they will not be sticky to the touch.

Store covered or in an airtight container at room for up to 5 days.


Place cut brownies on a baking sheet and freeze for 15-20 minutes or until hard enough that they won’t stick together. Freeze in a freezer-safe container or bag for up to 3 months.


I haven’t tested this myself, but it should work if you use a cup-for-cup gluten-free flour blend.


Yes, it will make the brownies darker and a little more rich with chocolate flavor.
