Method
- Step 1: Preheat the OvenStart by preheating your oven to 350°F (175°C). This ensures that your cookies bake evenly.
- Step 2: Prepare the Dry IngredientsIn a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Set this mixture aside as you work on the wet ingredients.
- Step 3: Cream the Butter and SugarIn a large mixing bowl, beat the unsalted butter and sugar together using a wooden spoon or an electric mixer. Mix until the mixture is light and fluffy, which should take about 3-4 minutes.
- Step 4: Add the Egg Yolks and FlavoringsOnce your butter and sugar are well combined, add the egg yolks, vanilla extract, lemon juice, and lemon zest. Mix until everything is well incorporated.
- Step 5: Combine Dry and Wet IngredientsGradually add the flour mixture to the wet ingredients, alternating with the milk. Start and end with the flour mixture, mixing until just combined. Be careful not to overmix!
- Step 6: Fold in the WalnutsGently fold in the ground walnuts until evenly distributed throughout the dough. This will give your cookies that delightful crunch.
- Step 7: Prepare the Dough for BakingUsing a tablespoon or cookie scoop, drop rounded balls of dough onto the prepared baking sheet, spacing them about 2 inches apart. Flatten each ball slightly with the palm of your hand.
- Step 8: Add Nutella and Cocoa MixtureIn a small bowl, mix the Nutella, cocoa powder, sugar, rum extract, and milk until smooth. Use a spoon to create a small indentation in the center of each cookie and fill it with the Nutella mixture.
- Step 9: BakePlace the baking sheet in the preheated oven and bake for 12-15 minutes, or until the edges are lightly golden. The centers may look a little soft, but they will firm up as they cool.
- Step 10: Cool and ServeOnce baked, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a cooling rack. If desired, dust with icing sugar before serving.
Notes
- Store cookies in an airtight container at room temperature for up to a week.
- If you want to keep them longer, freeze the baked cookies in a freezer-safe container for up to three months.
- To reheat, place cookies in a warm oven for about 5 minutes before serving.
