Lunchbox brownies are the sturdy, fudgy squares that survive the trip to school and back: cacao nibs melted with coconut oil into a rich batter, studded with toasted pecans. They cut clean once cool and hold their crumb for days. Bake Sunday, pack all week.
Pro Tips
- Line the pan with a foil sling and grease it well. It is the difference between clean squares and a crumbled batch.
- Microwave the coconut oil and cacao nibs slowly, stirring often, so the nibs melt smoothly without scorching.
- Cool the melted mixture slightly before whisking in the eggs. Warm batter scrambles.
- Bake until a toothpick comes out with just a few moist crumbs, 22 to 27 minutes. Dry crumbs mean dry brownies.
- Cool completely in the pan, about 2 hours, before cutting. Warm brownies fall apart long before the lunchbox.
Frequently Asked Questions
How long do lunchbox brownies keep?
Up to 5 days in an airtight container at room temperature. Their sturdy crumb is exactly why they are named for the lunchbox.
Can I leave out the nuts?
Absolutely. Sprinkle the top with extra chopped cacao nibs instead, or leave them plain for nut-free lunchboxes.
Can I freeze them?
Yes. Cut the cooled squares, wrap them individually, and freeze for up to 2 months. They thaw by lunchtime.
Are these brownies paleo?
Yes. Cacao nibs, coconut oil, almond flour, palm sugar, eggs, and pecans: grain-free, dairy-free, and lunchbox-tough.
