Step‑by‑Step Instructions for Millionaire’s Shortbread Sandwich Cookies
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This essential first step ensures that your Millionaire’s Shortbread Sandwich Cookies will bake evenly, developing that perfect golden crust. Take a moment to gather your baking equipment, including an 8-inch square baking pan and mixing bowls to make the process smooth and organized.
Step 2: Cream the Butter and Sugar
In a mixing bowl, cream together 1 cup of softened butter and ½ cup of granulated sugar using a hand mixer or stand mixer. Beat on medium-speed for about 3 minutes until the mixture is light and fluffy, appearing pale in color. This creaming step introduces air into the butter, which will create a delightful texture for your cookie base.
Step 3: Combine Dry Ingredients
Gradually add in 1 ½ cups of all-purpose flour and ½ cup of cornstarch to the creamed butter and sugar mixture. Mix on low speed until you see a dough form, ensuring everything is well combined. The dough should feel soft and slightly sticky, perfect for pressing into the baking pan.
Step 4: Pack the Dough into the Pan
Carefully press the cookie dough into the greased 8-inch square baking pan, spreading it evenly across the bottom. Use your hands or a spatula to ensure that it's firmly packed down, creating a smooth, level surface. This will help the Millionaire’s Shortbread Sandwich Cookies rise beautifully while baking.
Step 5: Bake the Shortbread
Place the baking pan in your preheated oven and bake for 20-25 minutes. Keep an eye on it as it bakes until the edges turn golden brown and the center is set. Once done, remove the pan from the oven and let it cool completely in the pan to maintain its softness for layering.
Step 6: Add the Caramel Layer
Once the shortbread has cooled, spread a generous layer of caramel sauce evenly over the baked shortbread. Use a spatula to ensure it covers the surface smoothly, creating that signature gooey layer. Enhance the flavor of your Millionaire’s Shortbread Sandwich Cookies by using homemade caramel if you have it!
Step 7: Melt the Chocolate Chips
In a saucepan over low heat, melt 1 cup of chocolate chips, stirring often until the chocolate is completely smooth and glossy. Be cautious not to overheat, as burnt chocolate can ruin the setup. Once melted, remove from heat and let it cool slightly before drizzling over the caramel layer.
Step 8: Finish with Chocolate Drizzle
Drizzle or spread the melted chocolate over the caramel layer, making sure to cover it well. Allow the chocolate to set at room temperature for about 30 minutes, until it hardens slightly but is still soft enough for cutting. This decadent layer adds a rich finish to your Millionaire’s Shortbread Sandwich Cookies.
Step 9: Cut and Serve
Once the chocolate is set, cut the shortbread into squares or sandwich pieces with caramel and chocolate inside. If you like, refrigerate the cookies briefly to help them hold their shape better. Serve them chilled for an extra treat or at room temperature to share with friends and family!

Tips for the Best Millionaire’s Shortbread Sandwich Cookies
Perfect Caramel: Use homemade caramel if possible, as it enhances the flavor and allows you to control the sweetness.
Avoid Overbaking: Keep a close eye on the oven—remove the shortbread when it turns golden brown, as it will continue cooking slightly after being taken out.
Smooth Chocolate: Stir the chocolate chips frequently while melting to prevent burning, ensuring a silky smooth finish for your cookies.
Press Firmly: When packing the dough into the baking pan, press down firmly to create an even base that will hold together well after baking.

Millionaire’s Shortbread Sandwich Cookies Recipe FAQs
How do I choose the right butter for my cookies?
Absolutely! For the best flavor and texture in your Millionaire’s Shortbread Sandwich Cookies, I recommend using unsalted butter that is softened to room temperature. This allows for better creaming with the sugar, resulting in a light and fluffy dough. If you’re using salted butter, you might want to reduce the added salt in the recipe or skip it altogether.
How should I store these cookies?
To maintain the freshness of your Millionaire’s Shortbread Sandwich Cookies, store them in an airtight container in the refrigerator for up to a week. This keeps the caramel from becoming too sticky while preserving the lovely shortbread texture. I often place parchment paper between layers for added protection and to absorb any excess moisture!
Can I freeze these cookies, and how should I do it?
Yes, you can absolutely freeze these divine cookies! To do so, first wrap individual cookies tightly in plastic wrap, ensuring no air pockets are left. Then, place them in a freezer-safe container. They’ll keep well in the freezer for up to 3 months. When you're ready to enjoy, take the cookies out and let them thaw in the refrigerator for a few hours to maintain their beautiful texture.
What are some common issues I might encounter while making these cookies?
One common issue is if your shortbread is too crumbly. This often happens if the butter is too cold or the dough isn't mixed enough to hold together properly. If you notice this, you can add a teaspoon of milk to help the dough bind. Also, remember to press the dough firmly into the baking pan—this ensures your Millionaire’s Shortbread Sandwich Cookies hold together beautifully when baked!
Are there any dietary considerations I should keep in mind?
Definitely! If you're serving these cookies to someone with allergies, be aware that they contain gluten (from all-purpose flour) and dairy (from butter and chocolate). For a gluten-free version, you can substitute all-purpose flour with a gluten-free blend. Also, check that your caramel and chocolate chips are allergy-friendly if needed. Enjoy these cookies safely!
