👩🍳 Instructions
Step 1: Prepare the Baking Pan
Preheat your oven to 350°F (175°C).
Grease and line a 9×13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, whisk together the eggs, granulated sugar, cocoa powder, and vanilla extract until smooth and well combined.
Slowly pour in the melted butter while whisking continuously until fully incorporated.
Step 3: Add the Dry Ingredients
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the chocolate mixture, stirring gently until just combined.
Do not overmix, as this can make the brownies less tender.
Step 4: Bake
Pour the batter into the prepared baking pan and spread it evenly with a spatula.
Bake for 20–25 minutes, or until the top is set and a toothpick inserted near the center comes out with a few moist crumbs attached.
Avoid overbaking to keep the brownies rich and fudgy.
Step 5: Prepare the Chocolate Frosting
While the brownies are baking, prepare the frosting.
In a large bowl, beat together the softened butter, powdered sugar, cocoa powder, milk, corn syrup, and vanilla extract until smooth, creamy, and spreadable.
If needed, add a little more milk to reach your desired consistency.
Step 6: Frost the Brownies
Allow the brownies to cool for about 10 minutes.
Spread the chocolate frosting evenly over the warm brownies using an offset spatula or the back of a spoon.
The warmth of the brownies will slightly soften the frosting, creating the classic Lunch Lady Brownie texture.
Step 7: Cool and Serve
Allow the brownies to cool completely before slicing into squares.
Serve at room temperature and enjoy with a glass of cold milk or a cup of coffee.
💡 Baker’s Tips
- Use room-temperature eggs for a smoother batter.
- Sift the cocoa powder before mixing to prevent lumps.
- Do not overmix the batter once the flour is added.
- Frost the brownies while they are still slightly warm for the signature soft frosting layer.
- For perfectly clean slices, chill the brownies for 30 minutes before cutting and wipe the knife clean between cuts.
