Step 1- Preheat the oven to 375F. Line 2 baking sheets with parchment paper

Step 2- Mix the flour and baking soda together in a bowl and set aside.

Step 3- Melt 10 tablespoons in a skillet (not a non-stick skillet it can make it difficult to see when the butter is sufficiently browned). Melt the butter until it’s dark golden brown (1 to 3 ) minutes.

Step 4- Once it’s browned, set it aside and then add the remaining tablespoons of butter and stir until completely melted.

Step 5- Add the brown sugar, regular sugar, vanilla, and salt to the butter, mix it until it’s fully incorporated. Then add the egg and the yolk, mix it until it’s completely mixed together and smooth.

Step 6- Once that is completely smooth and shiny, stir in the flour mixture until it’s all mixed consistently.

Step 7 -So in order to get the strawberry jam to not be a mess, take about a tablespoon and a half of dough, roll it flat, then add a tsp. of the jam, then put another tablespoon and a half of dough over it to seal it, you'll have to eyeball it to get it to work, it's an inexact process.

Step 8-  Space them 2 inches apart on the prepared sheets.

Step 9- Then bake one sheet at a time until they are golden brown, puffy, and the edges have set (you want the center to be soft). Cook for about 9 to 12 minutes, 9 if you want super soft, 12 if you want more crunch. If you're living dangerously at 9 I advise that once you take them out of the oven throw them in the fridge with the cookie sheet or the freezer to help solidify the whole thing.

Step 10 - Stuff your face!
