For the cookie dough:
- 6 1/2 tablespoons (90g) unsalted butter, at room temperature
- 1/2 cup (80g) powdered sugar
- 1 egg, at room temperature
- 1 teaspoon vanilla extract
- 1 2/3 cups (215g) all-purpose flour
- 2 tablespoons (15g) cornstarch
- 1/2 teaspoon baking powder
- Pinch of salt
- 1/2 cup smooth strawberry jam (not chunky)
For the glaze:
- 3/4 cup powdered sugar
- 2-3 tablespoon lemon juice or milk
For the cookie dough:
- Butter or use baking spray to grease cookie sheets or line them with parchment paper.
- In a large bowl, beat (with a hand mixer or wooden spoon) butter and sugar until creamy.
- Add egg and beat until well combined.
- Add vanilla and mix.
- Add sifted flour, cornstarch, baking powder and salt. Mix everything well. The dry ingredients can be sifted before in another bowl if that's more convenient for you. I have them measured and sift them directly over the butter mixture.
- It will be a smooth and tender dough.
- Take teaspoons of dough and form balls no more than 1-inch wide. Don't make large balls as they will take too long to bake and the jam will end up being too dry and probably spill.
- Place them on the prepared baking sheets with space between them.
- Make an indentation in each piece of dough. The hole should not reach the bottom and break the dough. Tip: I use the bottom part of a small measuring spoon (1/2 teaspoon size).
- Put the whole baking sheet in the fridge for 30 minutes. This chills the dough so it doesn't spread or change its shape too much when it bakes.
- Preheat the oven to 350°F/180°C.
- Important: I always recommend doing a test run with 2-3 cookies to check the amount of jam to use and the time they take to bake, so they are soft and not spilled. Don't bite into them immediately as the jam is very hot.
- Put a small amount (scant 1/2 teaspoon) of strawberry jam in each hole. It should not reach the top of the indentation, or it will spill.
- Bake for about 12 minutes and check the cookies. They should be dry and lightly browned with the jam bubbling. They might take a couple of minutes more depending on your oven and the size of your cookies.
- Cool on a wire rack before eating, as the jam center is very hot.
- Drizzle some glaze on top and let it dry before eating.
- Store in airtight tins or cookie jars.
For the glaze:
- Mix the powdered sugar with 2 tablespoons of the juice or milk in a medium bowl until smooth and creamy.
- Drizzle over a cookie and see if you like it or want it thicker or thinner. Add more sugar to thicken it or more liquid to thin it, always a very small amount at a time until you reach the desired consistency.
- Organization: read the recipe first and ensure you have ingredients at the correct temperature, equipment, and enough workspace. This will make the process so much easier.
- Baking time: keep in mind that all ovens and pans are different, even if they look the same or very similar. The baking time in my recipes is as accurate as it can be, but it might take you more or less time. You can use a thermometer(like the OXO oven thermometer) to check that your oven is at the right temperature. I recommend you keep track of how your oven works and what tiny details you need to adjust.
- Test bake: I always recommend doing a test run with 2-3 cookies to check the amount of jam to use and the time they take to bake, so they are soft and not spilled. Don't bite into them immediately as the jam is very hot.
- Make ahead: the cookie dough can be kept in the refrigerator for 3-4 days before use. Always cover it well to prevent dryness (I use plastic wrap over the bowl or transfer it to a glass container with a lid).
- Strawberry glaze: this is an eye-catching alternative you might want to try. We love it so much (use it on scones and cakes) there's a whole post on how to make a strawberry glaze.
- Glazed cookies: make sure they're completely cooled before drizzling the powdered sugar glaze. Otherwise, the heat will thin it out. When storing glazed leftover cookies, you might want to put pieces of parchment paper or freezer sheets between them, so they don't stick.
- Flavor variation: strawberry jam is a crowd-pleaser, but you can use other jams like raspberry or apricot, or jellies like quince. Flavor the dough with a touch of ground cinnamon or add 1/2 teaspoon of orange or lemon zest.
