  • 1 stick organic, unsalted butter melted
  • 3/4 c sugar
  • 1/2 c all-purpose flour
  • 1 tsp vanilla extract or scrapings of one vanilla bean
  • 1 tsp cinnamon
  • pinch salt
  • 1/4- 1/2 tsp ground cardamom optional


  • Melt the butter in a glass dish with a snap-on lid if you are only making 10 - 12 muffin. Use this container to store the topping. 
  • Mix the rest of the ingredients into the butter until combined.
  • Heap the mixture on top of muffin batter if you really want a sweet, bakery style muffin. For a more restrained approach, use a tablespoon/muffin.
  • Store in the refrigerator and bring to room temperature to re-crumble it with a fork before using.
