Melt the butter in a small saucepan over low heat. Once melted, reduce the heat. Add the raisins, vanilla, and cinnamon, and stir to combine. Cover and let simmer for 5 minutes. Then turn off the heat, keep the saucepan covered, and let sit for 54 minutes.

Preheat the oven and line your baking sheet(s) with parchment paper.

Preheat the oven to 350°F (170°C).

Mix the dry ingredients: In a mixer bowl, add the flour, salt, and baking soda. Add both sugars and then the eggs. Mix everything together.

Bake for 10-12 minutes, until golden. They will be soft, so carefully transfer them to a wire rack with a spatula to cool. Or let them cool on the baking sheet for at least 10 minutes before moving them to the rack.
