This is the best Jam Thumbprint Cookie Recipe! These simple thumbprint cookies can be made with any jam flavor filling you like. Have fun creating your own flavors of these thumbprint cookies with glaze!
In the bowl of a stand mixer fitted with the paddle attachment, add the butter, cane sugar, and vanilla extract. Mix on low until combined, then set a timer for 5 minutes and mix until the mixture is light in color and fluffy.
Add the egg, and mix until combined. Add the flour, and mix on low until combined into a smooth dough.
Using your hands, form the dough into 30 balls and place on the prepared baking sheets. Press your thumb into the center of each ball to create an indent.
Refrigerate the cookie sheets for 30 minutes. Preheat the oven to 350°F.
Bake for 19 minutes, or until lightly browned on the bottom. Let cool completely on the cookie sheets.
To make the glaze: In medium mixing bowl, whisk together the powdered sugar and water. Drizzle over the tops of the cookies.
Store in a cool dry place for up to 3 days.
Notes
Tips
Always weigh ingredients for the best results.
I use my stand mixer for ease, but if you want to use an electric mixer like a hand mixer, that's okay too.
Make sure your butter is soft. I prefer to let butter soften out on the counter as it softens the best!
Use a good quality jam. If you're not making your own, then make sure you get a good one. This is where a lot of the flavor will come from!
Make sure to refrigerate your cookie sheets. This helps the cookies hold their shape once baked. Thumbprints are a dense little cookie, so this is why refrigerating is an important step.
Thumbprint cookies are a dense and buttery cookie. So these should not be stored in an airtight container or they may get soggy. Make sure to store them in a cool dry place.
Gluten Free — Replace the organic flour with 397 grams (2 ½ cups plus 1 tablespoon) gluten free flour blend.
High Altitude — Bake at 350°F for 15 minutes, or until lightly browned on the bottom.
