In a large mixing bowl, beat butter with an electric hand mixer on medium speed for 30 seconds. (This recipe can also be made in a stand mixer.)
Add the sugar and almond extract and mix just until combined.
Spoon flour into a 1 cup measuring cup and level. Add the flour to the butter/sugar mixture and mix on low speed just until blended. Each cup of flour weighs 4.3-4.5 ounces.
Add the second cup of spooned four to the mixture and again mix just until blended. If the mixture is too heavy for your electric mixer, then stir the mixture with a sturdy spoon until well combined.. Do not over-mix.
Pinch off a small portion of dough and roll into a 1-inch ball. Place 12 dough balls on a prepared baking pan. I used a cookie scoop for consistency.
With the back of a round 1/2 teaspoon measuring spoon or other suggested object (see intro at top of page), form a depression in each dough ball, about halfway into the dough. If the dough cracks, gently push the edges back together. I have found that too much flour in the dough makes the dough less malleable and more likely to crack.
Fill the depression with 1/2 teaspoon of seedless raspberry jam or jam flavor of choice.
Bake for 10-12 minutes, just until bottom of cookies turn a very light brown. Place on cooling rack to cool completely before glazing.
