Instructions
Preheat the oven to 350°F with a rack in the middle position.
Line an 8" x 8" square baking pan with parchment paper. (See notes)
Shortbread
Place the butter and sugar in a food processor and pulse until smooth and fluffy, scraping down the sides occasionally with a rubber spatula. Add the lemon extract and process to combine. Sift in the flour and pulse until it is combined to form a dough. Add in ½ cup of the chopped macadamia nuts and pulse to just combine.
Place the dough mixture into the lined baking pan. Use your hands to firmly press down the mixture. Then, smooth slightly with the back of a flat 1-cup measure, if needed. Prick the shortbread with the tines of a fork, creating rows.
Place the shortbread in the oven and bake until light golden and firm, 30-35 minutes.
While the shortbread bakes, make the dulce de leche.
Dulce de Leche
Place the butter, sugar, syrup, salt, and condensed milk into a 2-qt saucier and heat over medium heat until melted, stirring often. Continue to simmer until the mixture has thickened and is golden, stirring constantly to prevent it from burning, 6 to 8 minutes.
For best results, use a candy thermometer. The dulce de leche is ready when the temperature reaches 225°F. Also, if you run a wooden spoon or silicone spatula down the middle of the dulce de leche, it should leave a clean trail along the bottom of the saucier. Remove from heat and whisk in the vanilla extract.
Pour the dulce de leche mixture over the shortbread and use a spatula to smooth it out evenly. Leave the banking pan on a cooling rack to cool completely.
Once the shortbread and dulce de leche have cooled, prepare the ganache.
Ganache
Place the chocolate chips in a heatproof bowl. Then, heat the whipping cream in a small saucepan to just a simmer, stirring occasionally. As soon as the cream begins to simmer, remove from heat and pour over chocolate chips. Gently stir to ensure that all the chocolate is covered.
Place a lid on the chocolate chips and let it sit for 5 minutes. Remove the lid and stir with a silicone spatula until the mixture is just smooth (try not to overmix).
Let the ganache sit at room temperature for 8 to 10 minutes before pouring it over the dulce de leche.
Toppings
Top with the remaining ½ cup of macadamia nuts and the crushed mini eggs.
Place in the refrigerator until completely set, at least 4 hours.
Slice and Serve
Store it in the fridge until about an hour before serving. Lift out the shortbread from the pan by holding the parchment. Using a large sharp knife, cut into pieces and serve at room temperature.

Pro Tips:
- Prepare Ingredients in Advance: Ensure all ingredients are at room temperature before starting, especially the butter. This helps in achieving a smoother texture and better incorporation of ingredients.
- Line the Pan Properly: Use parchment paper to line the baking pan, allowing for easy removal of the bars once they are set. Make sure the paper hangs over the edges for easy lifting.
- Monitor Shortbread Baking: Keep a close eye on the shortbread while it bakes to prevent it from over-browning. It should be light golden and firm to the touch when done.
- Test Dulce de Leche Consistency: Use a candy thermometer to ensure the dulce de leche reaches the proper thickness. It should register around 225°F and leave a clean trail when a spoon is dragged through it.
- Handle Ganache with Care: Be gentle when mixing the ganache to avoid overmixing, which can cause it to become grainy. Let it sit for a few minutes before pouring it over the cooled shortbread and dulce de leche layers.
- Chill Thoroughly: Allow the bars to chill in the refrigerator for at least 4 hours, or until completely set. This ensures clean, neat slices when cutting.
- Serve at the Right Temperature: For the best texture and flavour, serve the bars at room temperature. Take them out of the refrigerator about an hour before serving to allow them to soften slightly.
Storage Guidelines
Room Temperature Storage:
- Store the shortbread in an airtight container at room temperature for up to 3 days. Ensure the container is sealed well to prevent the shortbread from drying out.
Refrigeration:
- For extended freshness, place the shortbread in an airtight container and refrigerate. This method can keep the bars fresh for up to 1 week. Refrigeration also helps maintain the firmness of the caramel and chocolate layers.
Freezing:
- To store the shortbread for longer periods, freezing is an effective option. Wrap individual bars tightly in plastic wrap or aluminum foil, then place them in a freezer-safe airtight container or resealable bag. Properly stored, they can be frozen for up to 3 months. When ready to enjoy, thaw the bars at room temperature for about 30 minutes before serving.
