Jam Butter Cookies (Jammer Cookies)
Cookie bliss is defined as jam butter cookies filled with a dollop of blueberry jam. Officially called jammers or jammer cookies by cookie queen Dorie Greenspan, these cookies are a collision of buttery crumb bar, shortbread cookie, and jam thumbprint cookies. No matter what you call them, they are utterly delicious.
I love the combination of blueberry jam with good vanilla (and all that butter!). Raspberry or apricot jam paired with almond extract would be incredible as well.
No matter what flavor pairing you choose, this is one butter cookie to bake again and again.

How to Make Jam Butter Cookies
The best part of this recipe is that there’s no dough rolling or special equipment required here.
Baking pan – Two standard muffin pans are the perfect size for these cookies.
Crumb topping – Combine flour, sugars, salt, and cinnamon in a large mixer bowl and mix on low speed to combine. Add vanilla and butter, and mix on medium-low speed until fully incorporated and dough comes together in large crumbs. Transfer to a covered bowl and chill in the refrigerator for at least 1 hour.
Cookies – Beat butter, sugar, powdered sugar, and salt in a large mixer bowl on medium speed until creamy, scraping down the bowl as needed. Reduce speed to low and beat in egg yolks one at a time; mix in vanilla. Scrape down bowl and add the flour all at once; mix in on low speed until incorporated and dough comes together in large pieces.
Assemble – Use a cookie scoop to portion out the cookie dough into muffin cups. Press the dough evenly with the back of a metal measuring cup, then chill for 30 minutes before topping with a spoonful of jam and sprinkle of crumb topping.
Bake cookies – Bake cookies at 350°F for 20 to 22 minutes, until edges and crumb topping are golden. Cool in pans on a wire rack for 15 minutes, then carefully remove from pans and place on wire rack to cool completely.

Notes
Make ahead: Freeze assembled cookies in muffin pans, then wrap well and freeze up to 2 months. Bake directly from the freezer, adding 1-2 minutes to baking time.
