Alfajores Hidden Surprise Cookies Recipes

Steps:

• Mix flour, confectioners' sugar, cornstarch, and salt together in a bowl. Place butter in a separate bowl and use an electric mixer to beat until soft and fluffy. Add white sugar and vanilla and mix well.
• Add flour mixture to the bowl with the butter mixture in 3 stages; mix until just blended. Divide dough in half and roll each half into a log. Refrigerate dough logs until firm, about 2 hours.
• Preheat the oven to 350 degrees F (175 degrees C).
• Slice dough logs into 1/4-inch cookies and place on a baking sheet.
• Bake in the preheated oven until just starting to turn golden around the edges, 8 to 10 minutes.
• Allow cookies to cool on the pan for 1 minute. Transfer to wire racks to cool completely, about 30 minutes more.
• Use a knife to apply a generous amount of dulce de leche on one cookie. Sandwich another cookie on top and place on a serving tray. Repeat with remaining cookies and dulce de leche. Lightly dust finished cookies with confectioners' sugar.

Steps:

• Make the dulce de leche: Bring a large pot of water to a boil, then carefully lower condensed milk cans on their sides into the water. Simmer for 3 hours 15 minutes, refilling with hot water as needed to keep cans submerged. Never let the water boil away, or the cans could burst. Using tongs, transfer cans to a rack to let cool completely before opening.
• In a small bowl, combine brandy, lemon zest and 1 teaspoon vanilla.
• In a large bowl, whisk together flour, cornstarch, baking powder, baking soda and salt.
• In the bowl of an electric mixer, beat sugar and butter until light and fluffy, about 3 minutes. Add yolks and beat to combine, then add brandy mixture and beat until just combined. Add flour mixture, and mix on low speed until the dough just comes together.
• Divide the dough in half and roll each piece into a log about 1 1/2 inches thick. Wrap in plastic and chill until firm, at least 2 hours.
• Heat oven to 350 degrees. Line 3 baking sheets with parchment paper. Remove dough from plastic wrap and slice into 1/8-inch-thick rounds. Place on prepared sheet pans, then bake until edges start to turn golden, about 7 minutes. Transfer each pan to a rack to cool completely.
• In a small bowl, combine dulce de leche with remaining 1 teaspoon vanilla and a large pinch of salt. Spoon the mixture into a plastic zipper bag and cut a corner off. (Or you could scoop it into a pastry bag if you prefer, or just use a spoon.)
• Flip half of the cookies upside down and pipe a thick layer of dulce de leche onto bottoms (or use a spoon to spoon the mixture on). Top with remaining cookies to sandwich the dulce de leche in the middle. Roll sides in coconut. Eat right away, or store in the refrigerator until serving.

Steps:

• Combine the flour, corn flour and baking powder together in a bowl with a pinch of salt. Using a food mixer or an electric whisk in another bowl beat the butter together with the sugar and lemon zest until very pale. Add the egg yolks followed by the Cognac and vanilla extract. Beat in the dry ingredients until you have smooth dough. Wrap the dough in clingfilm and chill for a minimum of 1 hour. You can make the biscuit dough the day before and leave in the fridge.
• Line two large baking trays with baking parchment. Roll out the dough on a lightly floured surface to the thickness of a pound coin then cut out 60 biscuits with a 5cm round or fluted cutter. Put the biscuits back in the fridge for 20 mins to firm up.
• Heat the oven to 180C/160C fan/gas 4. Bake the biscuits for 8 mins until just set. You want the biscuits to stay pale with a crumbly texture. Leave to cool completely before sandwiching two biscuits together with a spoonful of dulce de leche. Once all the biscuits are sandwiched together roll in desiccated coconut.
