Mountain Baking
I can tell this person has never made a brownie mix before because they didn’t adjust for the altitude. In fact, I actually know what the altitude is in my hometown. I remember when I was younger and would see that on the back of the brownie mix box while baking. Then, I would go ask my mom what our current altitude was.
Did you know that brownie mixes are pretty universal? You don’t have to change anything whether you’re at a high or low altitude. I learned this from my mother- we would never be able to figure out if our city (with its average elevation) required high or low-altitude instructions. So, I started baking them for the recommended time on the box, and they always turned out fine.
