Blend the nuts into a flour-like consistency. A few larger pieces are fine!

Bring the heavy cream and sugar to a simmer.

Add the nuts and mix.

Add the butter and cardamom and fully combine.

Continue to mix over medium-low heat until the mixture thickens (you should be able to form a non-sticky ball with greased hands).

Transfer to a parchment paper-lined pan or tray and smooth out.

Decorate with sprinkles/chopped nuts/silver leaf and enjoy!!
