Learn how to make mincemeat cookies with this easy Christmas cookie recipe. This makes cookies very similar to the M&S mince pie cookies, soft and chewy with lots of mincemeat flavour.
Preheat the oven to 375 ºF (190 °C). Line two large sheet pans with parchment paper.
In a medium bowl, whisk together the flour, salt, and baking soda. Set aside.
In a large bowl, using an electric hand mixer or in the bowl of a stand mixer with the paddle attachment, cream together the butter, the granulated sugar, and the brown sugar until it's very light and fluffy.
Add the egg and the vanilla, and mix well until the mixture is light and fluffy again. Make sure to clean down the sides of the bowl as needed with a big spatula.
Stir in 100 grams (⅓ cup) of mincemeat to incorporate it.
Dump in the whisked dry ingredients, and incorporate them with the mixer on low.
Scoop approximately 50 gram portions of the dough, rolling them into balls.
Place 6–7 cookies per cookie sheet, being sure to space them apart and stagger them to allow for air circulation and spreading.
Using your thumb or the handle of a wooden spoon, create an indentation in the centre of each cookie. Fill with mincemeat, being sure to gently press it into the indentation to pack it in.
Bake the cookies, one sheet pan at a time, until the edges just begin to brown (this takes about 16 to 18 minutes). You might want to rotate the pan partway through the baking to make sure the cookies brown evenly.
Let the cookies cool completely on the sheet pan while you bake the second pan.
