Author Notes: I solved the "problem" of having a glut of organic milk on hand by deciding to make dulce de leche the old-school way. When I found myself with the ensuing "problem" of too much dulce de leche, I found that these cookies were an easy, crowd-pleasing answer. The last step of this recipe explains how to store the cookies, but they'll probably be gone before you can say "airtight container." - vvvanessa
Serves 3-4 dozen
Dulce de Leche
- 1 quart full-fat organic milk
- 1/2-3/4 cup sugar (turbinado or another, less-refined sugar is preferable)
- scant 1/2 teaspoons baking soda
- In a heavy- bottomed sauce pan with at least a 2-quart capacity, dissolve the sugar in the milk over medium-high heat.
- Once the sugar is dissolved, stir in the baking soda.
- Bring the milk to a near-boil, taking much care not to let it boil over. Just as it's coming to a boil, lower the heat to low and allow the mixture to simmer uncovered for 1-2 hours, stirring often (a silicone spoon or spatula is especially handy for this job). It should look like it's simmering a bit vigorously but not actually be at a full boil.
- Remove the pan from the heat when the milk becomes a dark golden color and appears quite thick. A good test to know when it's done is to stir the mixture with a spoon and run your finger along the back of the spoon (careful-- it's hot!); the trail your finger leaves should last several seconds before slowly disappearing.
- Allow dulce de leche to cool to room temperature.
- 1 1/2 cup all-purpose flour, plus more for rolling out the dough
- 1/2 cup cornstarch or non-glutinous rice flour
- 1/2 teaspoon baking powder
- 1/2 cup unsalted butter at room temperature
- 1 cup granulated sugar
- 1/2 teaspoon table salt
- 1 large egg, lightly beaten at room temperature
- 2 tablespoons milk or cream
- 1 teaspoon vanilla extract
- In a small bowl, whisk together the flours and baking powder.
- In separate bowl, cream butter, sugar, and salt.
- Add egg, milk, and vanilla to the sugar mixture; mix well.
- Add dry ingredients to wet ingredients, and mix until incorporated.
- Shape dough into a few smaller portions, flatten into discs, wrap in plastic, and refrigerate until stiff, at least one hour or overnight.
- Heat oven to 350ºF degrees. Line cookie sheets with parchment or silicone mats.
- Roll out dough to 1/4-inch thickness on a lightly floured surface. Cut into shapes and move to baking sheets (cookies won't spread much so they can be set quite close together).
- Re-roll and re-cut dough scraps giving dough a bit more time in the fridge as necessary.
- Bake cookies until lightly golden, about 10 minutes. Transfer to wire racks to cool.
- To assemble the cookies, spread a 1/4-1/2 teaspoon of cooled dulce de leche on the flat side of the cookie and use another cookie, flat side in, to complete the sandwich.
- Store any unused dulce de leche in an airtight container in the refrigerator.
- Store cookies in an airtight containter at room temperature.
