A few years ago, I was having a party, and I wanted to have sugar cubes to serve alongside my coffee bar, because SO FANCY.

Only I couldn’t find sugar cubes, and Amazon Prime had not yet been invented. (I am 1 million years old).

So because I didn’t want my party planning to be a complete waste, I decided to make my own. The idea is pretty simple- sugar and water pressed together and left to dry out overnight.

Fast forward to 2016. Amazon Prime has been invented (praise be!), and I order this adorable heart-shaped silicone mold for no reason at all. One day as I was pretending to listen to my children talk about Minecraft, I thought these little hearts would make cute sugar cubes.

Only it was 20 minutes till date night, and I was also thinking about champagne. Homemade bitters-soaked sugar cubes for Valentine’s Day was born. As it turns out, I am not the first person in the history of the world to make angostura sugar cubes, but I may be the first person to make them positively adorable.

In my excitement, I forgot to add a twist of lemon to the cocktails. It was also 10:00 AM when I was shooting these, so that could have something to do with it.

These Champagne Cocktail Sugar Cubes are, of course, perfect for Valentine’s Day, but I will certainly be enjoying them for date night all year and, of course, on New Year’s Eve!

Alternative to a heart-shaped mold:

If you don’t have the heart silicone mold, you can pour the sugar into a container of any sort. Just score the wet sugar into squares with a paring knife. When dry, the perforated cubes will break apart easily.
