These cupcakes can be stored in the fridge for up to 3 days. However, they are best enjoyed at room temperature! I recommend letting them sit at room temperature for about an hour before serving.
To make brown butter, melt unsalted butter over medium heat, stirring frequently. Watch closely as the butter develops brown specks and releases a nutty aroma. Once you start seeing brown specks, cook for just a few more seconds (be careful, as it can burn quickly). Remove from heat and pour into a small bowl to prevent it from continuing to cook. Let it cool for about 20 minutes in the fridge until it becomes soft and pliable.
Note: When browning butter, you'll lose about 1 tablespoon (14g) of butter for every ½ cup (1 stick or 113g) due to evaporation. To compensate, you can add an extra tablespoon before browning, or if you're browning larger batches, adjust the weight with regular unsalted butter in your recipe as needed.
