Ingredients
The foundation of these fudge squares is a buttery Oreo crust that provides a crunchy contrast to the silky chocolate layer. Sweetened condensed milk acts as the primary sweetener, delivering a smooth, caramel‑like richness without the need for heavy cream. A touch of vanilla and a pinch of sea salt elevate the flavor, while the final dusting of crushed Oreos adds texture and visual appeal.
Crust & Base
- 24 Oreo cookies (about 1½ cups, crushed)
- ½ cup unsalted butter, melted
- 2 tablespoons granulated sugar
Fudge Layer
- 1 (14‑oz) can sweetened condensed milk
- 8 ounces semi‑sweet chocolate chips
- 2 teaspoons vanilla extract
- ¼ teaspoon fine sea salt
Finishing Touch
- 2 extra Oreo cookies, crushed (for topping)
These ingredients work together to create a balanced dessert. The butter‑infused crust holds the fudge in place, while the condensed milk provides sweetness without graininess. Chocolate chips melt into a glossy, velvety layer, and the vanilla plus sea salt sharpen the flavor profile, preventing it from becoming cloyingly sweet. The final sprinkle of crushed Oreos adds a pleasant crunch that mirrors the base.
Step-by-Step Instructions

Preparing the Crust
Begin by preheating your oven to 350°F (175°C). While it heats, place the 24 Oreo cookies into a zip‑top bag and crush them with a rolling pin until fine. Transfer the crumbs to a medium bowl, stir in the melted butter and sugar until the mixture resembles wet sand, then press firmly into the bottom of a greased 9‑inch square pan. The butter helps the crust set and adds a subtle richness.
Baking the Base
Bake the pressed crust for 8‑10 minutes, just until it turns a light golden brown. This short bake firms the base without drying it out, creating a sturdy platform for the fudge. Remove from the oven and let it cool slightly while you prepare the chocolate mixture.
Making the Fudge
- Combine liquids. In a saucepan over low heat, whisk together the sweetened condensed milk and chocolate chips. Stir continuously for 4‑5 minutes until the chocolate fully melts and the mixture becomes glossy. This slow melt prevents scorching and ensures a silky texture.
- Flavor the mixture. Remove the pan from heat and stir in vanilla extract and sea salt. The vanilla adds depth, while the salt cuts through the sweetness, balancing the overall flavor.
- Pour over crust. Quickly but carefully pour the warm fudge over the pre‑baked crust, spreading it with a spatula to the edges. The warmth helps the fudge set evenly as it cools.
Cooling & Finishing
Allow the pan to cool at room temperature for 15 minutes, then sprinkle the crushed Oreo topping evenly across the surface. Transfer the entire pan to the refrigerator and chill for at least 2 hours, or until the fudge is firm enough to cut cleanly. This chilling step solidifies the fudge while preserving its melt‑in‑your‑mouth softness.
Serving
Remove the pan from the fridge, lift the fudge out using the parchment paper (if you lined the pan), and place it on a cutting board. Using a sharp knife warmed in hot water, slice the dessert into 24 even squares. Serve chilled or at room temperature for maximum flavor.
Tips & Tricks
Perfecting the Recipe
Crush uniformly. Use a food processor for evenly sized crumbs; this prevents clumps in the crust and ensures consistent baking.
Press firmly. A flat-bottomed glass or the back of a measuring cup creates a compact crust that won’t crumble when sliced.
Don’t over‑bake. Keep the crust just golden; over‑baking dries it out, making the fudge slide off.
Warm the knife. Run a knife under hot water before each cut to achieve clean, professional‑looking squares.
Flavor Enhancements
Stir a tablespoon of espresso powder into the fudge for a subtle coffee note, or swirl in caramel sauce for a ribbon effect. A pinch of smoked sea salt on top adds a sophisticated contrast that elevates the dessert.
Common Mistakes to Avoid
Avoid using cold butter in the crust—it won’t bind properly. Also, don’t skip the cooling step; cutting the fudge while warm leads to messy, uneven pieces. Finally, keep the pan covered when refrigerating to prevent the fudge from absorbing fridge odors.
Pro Tips
Use high‑quality chocolate. A good semi‑sweet chocolate gives a richer flavor and smoother texture than lower‑grade chips.
Line the pan. Parchment paper makes removal effortless and preserves the square shape.
Adjust sweetness. If you prefer less sweet, substitute half of the condensed milk with evaporated milk and add a tablespoon of maple syrup.
Scale up. Double the recipe and bake in a 9×13‑inch pan for a larger batch; just increase baking time by 5 minutes.
Variations
Ingredient Swaps
Replace the classic Oreo with chocolate‑wafer cookies for a lighter crunch, or use peanut‑butter cookies for a nutty twist. For a fruity version, fold in chopped dried cherries into the fudge before pouring. White chocolate chips can substitute the semi‑sweet chips for a creamy, ivory‑colored square.
Dietary Adjustments
To make the dessert gluten‑free, ensure the Oreo‑style cookies are certified gluten‑free. For a dairy‑free version, swap butter for coconut oil and use dairy‑free chocolate chips. Vegan seekers can replace sweetened condensed milk with a canned coconut milk sweetened with maple syrup and a pinch of xanthan gum for thickness.
Serving Suggestions
Serve each square with a dollop of whipped cream or a scoop of vanilla ice cream for extra indulgence. A drizzle of raspberry coulis adds a bright, tangy counterpoint. For a festive touch, dust the top with edible gold leaf or colorful sprinkles.
Storage Info
Leftover Storage
Allow any remaining squares to cool completely, then transfer them to an airtight container. Store in the refrigerator for up to 5 days. For longer keeping, wrap individual portions in plastic wrap, place in a freezer‑safe bag, and freeze for up to 3 months. Proper sealing prevents freezer burn and preserves the fudgy texture.
Reheating Instructions
To enjoy warm fudge, microwave a single square on medium power for 10‑15 seconds, or place a serving on a plate and warm in a 300°F oven for 5‑7 minutes. Add a splash of milk or extra chocolate sauce if the texture feels too firm after reheating.
