Brownie
Personal Connection:
Colorado tends to have a high altitude, and
this includes Durango. This altitude can
create problems in baking and cooking.
Baked goods can end up flat, dry, or too
sugary. When day dreaming about
decadent desserts, brownies are an iconic
sweet treat that is bound to come to mind.
Who doesnt love a perfect brownie with a
flaky top, crispy edges, and gooey center?
Both of these ideas led us to undertake the
task of creating the best brownie possible.
First, Nicole baked a recipe for brownies
without any altitude adjustments. These The first batch of brownies, made with
brownies were very thin and tasted strongly normal sugar, turned out with a nice buttery
of olive oil. This attempt led us to seek a flavor, gooey on the inside, crispy on the
high altitude brownie recipe. During school outside, and basically everything you could
the next week, we found a new recipe that want from a brownie. The honey batch
made corrections for higher altitudes. We while good in theory had some issues.
then made the necessary calculations to These brownies ended up thick, dry,

We spent two lovely Sundays baking six They resembled a failed cake rather than
batches of chocolatey delicious brownies, brownies. Finally, the maple syrup brownies

syrup in place of sugar. cake that would pair well with a homemade
buttercream frosting. Through the baking
process, and many taste tests, it was
determined that traditional brownies are still
the best. In conclusion, if its not broke,
dont fix it. Traditional brownies are a
classic for a reason; nothing else can
capture the essence of a brownie but a
traditional brownie. Even changing one
aspect of the recipe dramatically affects the
brownieness of the final product.
