The quatre-quarts is a Breton cake whose name comes from its composition: four ingredients in equal parts, butter, sugar, eggs, and flour. This simplicity makes it an easy cake to remember and to make successfully. Its dense and buttery crumb, golden crust, and straightforward flavor have made it a classic snack.
The secret to a moist quatre-quarts lies in creaming the butter well with the sugar and adding the eggs one by one. The eggs are weighed to adjust the other ingredients to their weight, which ensures balance.
