Why This Homemade Brownie Mix Recipe Works
Making your own mix lets you skip the preservatives and extra additives found in boxed versions while keeping the convenience. You also control the quality of the cocoa and the chocolate.
Espresso powder deepens the cocoa flavor without making the brownies taste like coffee. Oil keeps the crumb soft, and a little baking powder gives only a slight lift for a dense, fudgy bite.
The ratio of sugar and chocolate to flour is high, which is exactly what creates a chewy center and a thin crackly top.
Ingredients for Homemade Brownie Mix
- 1 cup granulated sugar
- 1/3 cup unsweetened cocoa powder
- 1/2 cup all purpose flour
- 3/4 teaspoon instant espresso powder (optional)
- 1/4 teaspoon baking powder
- 1/4 teaspoon kosher salt
- 1 cup semisweet chocolate chips (optional)
- 1/2 cup vegetable oil (added when baking)
- 2 large eggs (added when baking)
- 1 teaspoon pure vanilla extract (added when baking)
Cocoa powder. Unsweetened cocoa gives the deepest flavor. Sift it if it is lumpy so it blends evenly.
Espresso powder. A small amount boosts the chocolate flavor. Leave it out if you prefer.
Chocolate chips. Semisweet chips melt into pockets inside the brownies and add flavor to the jar.
Vegetable oil. Oil gives a moist, fudgy texture. Use a neutral oil.
Large eggs. They bind the batter and make the brownies set with a shiny top.
How to Make Homemade Brownie Mix
1. Whisk the dry ingredients Combine the sugar, cocoa, flour, espresso powder, baking powder, and salt in a medium bowl and whisk until no cocoa lumps remain.
2. Add the chips and jar it Stir in the chocolate chips, then spoon the mix into a clean quart jar and tap it to settle.
3. Heat the oven When you are ready to bake, heat the oven to 350 degrees F and grease an 8×8 inch pan, lining it with parchment if you like.
4. Add the wet ingredients Tip the mix into a large bowl and stir in the oil, eggs, and vanilla until the batter looks thick and glossy.
5. Bake the pan Spread the batter into the pan and bake for 20 to 25 minutes. A toothpick should show a few moist crumbs.
6. Cool and slice Let the brownies cool for 30 minutes, then cut into 9 squares.
How to Serve Homemade Brownie Mix
Serve the warm brownies with vanilla ice cream or a drizzle of silky chocolate ganache. For a bakery style plate, frost them with creamy chocolate buttercream and add a cookie like thick chocolate chip cookies. Tie a note to the gift jar that points to fudgy chocolate chunk brownies for another idea.
How to Store and Reheat Homemade Brownie Mix
Keep the dry mix in an airtight jar in a cool, dry place for up to 3 months. Shake the jar before using so the cocoa stays evenly mixed. Once baked, store the brownies in an airtight container at room temperature for up to 4 days. Freeze cut squares for up to 3 months, then thaw at room temperature.
Tips and Variations for Homemade Brownie Mix
Measure flour carefully. Spoon the flour into the cup and level it so the brownies do not turn dry.
Label the jar. Write the baking instructions and date on a tag so the mix is easy to use later.
Use fresh baking powder. Old baking powder can leave the brownies flat.
Try add ins. Stir in chopped nuts or dried cherries when you add the oil.
Try melted butter. Replacing the oil with melted butter gives a richer, fudgier taste.
Skip the raw batter. The batter contains raw eggs and raw flour, so only taste the baked brownies.
Do not overbake. Remove the pan while the center still looks slightly soft.
Store leftovers safely. Refrigerate any frosted brownies within two hours, following the University of Minnesota Extension guide to storing leftovers for safe handling.
