Baking brownies from the inside out

Summary by Krater

The creator attempts to design and engineer a brownie pan that eliminates corners and ensures every piece has the edge texture, testing various prototypes with his wife before building a final spiked metal pan.

Answers: How can you make a brownie pan with all edges and no center?

• Brownie edge texture
• Heat transfer in baking
• Pan design and engineering
• Thermal conductivity of aluminum
• Mechanical testing of food texture

What it concludes

• Brownie edges are tougher due to heat transfer from the pan sides, which heat up faster as energy migrates toward the center.
• A standard brownie pan creates overcooked corners because energy enters from two sides, heating those areas faster.
• An aluminum rod can act as a pipeline to bring heat directly into the center of a brownie.
• A spiked metal pan successfully bakes brownies from the inside out, creating uniform edge texture across the entire piece.
