Brownie Experiment-Along
Hi!
Great that you’d like to join us in our brownie experiment-along! Here we can gather your results and input, discuss your findings and share new ideas.
It’s a work in progress, so if you have any ideas on how to make this easier/better, let me (Annelie) know at scienchef@foodcrumbles.com.
Need a reminder of what the experiment-along is all about? Read the full post here.
Goal
In short, we want to know why and when a brownie has a crispy smooth top. Much like brownie C in the photo below.

Suggested hypotheses to test
In the article, I come up with 6 hypotheses that I’ve found from various sources. I’d like to know whether these are true/false. You can pick any of these to test, or, just can test a hypothesis you came up with yourself!
- Whipped eggs are key: You can only get a crackly top by whisking the eggs into a light and fluffy foam. Gently fold these into the brownie batter and bake immediately.
- Creaming sugar & butter is key: You have to cream the butter and sugar before adding in any dry ingredients.
- Note, this hypothesis would mean that recipes that use molten butter or oil won’t work?
- Mixing sugar into molten butter & chocolate is key: You have to melt the butter and chocolate on forehand and add the sugar while the butter and chocolate are still warm.
- A) More chocolate = less crust B) More chocolate = more crust: Yes, I’ve found both statements on the world wide web, which one is true? Does adding (molten) chocolate help to get that crackly top?
- Refrigerate the batter overnight
- Using icing sugar is key: Using icing sugar instead of granulated sugar helps to create a crackly crust.
So how does this platform work? I’m trying to figure out a (private) platform that allows everyone who wants to join an experiment-along to join in and contribute, both while the experiment-along is running, as well as afterwards.
