How to freeze individual Frosted Brownies


Frosted chocolate brownies this good must be frozen so you don’t end up eating too much. Some readers have called this a Texas Sheet Cake, which I’ve never tried until now. And I’ve been missing out. Here’s a modified, slightly healthier version for your lunch box treats.

Freezer Friendly Frosted Brownies


  • 1 cup cold water
  • 1/2 cup oil
  • 1/2 stick butter
  • 1 1/2 cups sugar
  • 2 cups flour (I used white whole wheat flour)
  • 4 Tbsp cocoa
  • 1/2 cup buttermilk
  • 1 tsp soda
  • 2 eggs, lightly beaten
  • Frosting
  • 1/4 cup buttermilk
  • 3 Tablespoons stick butter
  • 2 Tbsp cocoa
  • 2 cups powdered sugar
  • 1 tsp vanilla


  1. Preheat oven to 400 F.
  2. Grease a large jelly roll pan (or cookie sheet with rim). In a saucepan, boil cold water, oil, and butter.
  3. In a medium bowl, combine sugar, flour and cocoa. Add the boiled mixture to bowl and mix completely.
  4. Add buttermilk and soda to the mixture.
  5. Mix in the beaten eggs.
  6. Bake for 15 minutes. Cool.
  7. While the brownie is baking, prepare frosting.
  8. In the same saucepan, boil buttermilk, butter and cocoa.
  9. Remove from heat and use the same batter bowl, add powdered sugar, and vanilla. Blend until smooth.
  10. When brownies are cool, pour frosting over top, spreading evenly with a spatula to the edges. The frosting will seem very runny, but it sets up as it cools.
  11. Freezing Directions:
  12. Cool completely. Cut into 24 equal sized brownies. Flash freeze in a plastic box with wax paper between.
  13. Transfer to gallon freezer bag and freeze up to 3 months.
  14. TO SERVE: Thaw on counter or lunch box.

Once the brownies are frosted, I cut them into squares to prepare for freezing. Isn’t this much better than dazing at chocolate all day or worse throwing out food after a few days? It’s called portion control;)

Here’s where I use my handy dandy plastic shoe box for flash freezing individual servings. I use a 6-quart box for thawing and freezing, it’s a must for freezer cooking. I’ve separated the squares and placed them 1/2 inch a part between sheets of wax paper.

They stack nicely inside this box and freeze for a few hours. Once they’re solid, you can transfer to a gallon size bag with the air squeezed out for longer term storage, up to three months. However, if you’re like us and you love these brownies and want a daily treat in your lunch box. They can go straight into the lunch box frozen and thaw by noon. They are gone within a week so what’s to freezer burn? The container’s empty…

Have you ever individually frozen your sweet treats?
