How to Make the Brownies

When it’s time to bake, here’s how simple it is:

In a bowl, combine the jar’s contents with eggs, water, oil, and vanilla. Mix until smooth.
Pour the batter into the prepared pan and spread it evenly.
Bake for 35–40 minutes, or until a toothpick inserted in the center comes out clean.
Let the brownies cool before cutting into squares and serving.

Tips for Gifting

Presentation: Use festive ribbons, fabric covers, or custom tags to match the season or occasion.
Bundle It Up: Pair the jar with a spatula, brownie pan, or mug for a complete gift set.
Personal Touch: Include a handwritten note or a list of suggested add-ins like nuts, caramel, or marshmallows.
