This no-bake chocolate slice has become my go-to for those afternoons when I crave something sweet but don’t want to turn on the oven. It’s surprisingly forgiving, and the best part? It comes together in about 15 minutes, with ingredients I usually have on hand. Perfect for lazy weekends or last-minute get-togethers where I want something homemade but effortless.
I remember the first time I made this as a quick treat for friends who showed up unexpectedly. The rich aroma of melting chocolate and toasted nuts filled the kitchen, and before I knew it, everyone was asking for the recipe. It’s a recipe that’s stuck around because it’s honest, no-fuss, and always a hit when I need a little sweet pick-me-up.
This recipe is my secret weapon for when I need a quick, satisfying treat that doesn’t require turning on the oven, especially on hot summer days or during a chaotic week. It’s simple enough for kids to help with, yet indulgent enough for grown-up chocolate cravings. I love how it’s a no-fuss, no-need-to-clean-up dessert that always feels like a little victory.
The story behind this recipe
- This recipe sprouted from a busy afternoon when I needed something sweet but had zero energy to cook. I wanted the kind of treat that could come together in the time it takes to brew a coffee. It’s funny how a simple mix of chocolate and butter can make everything feel a little more manageable, even on chaos days.
- I remember the first time I made it for my kids after school. The smell of melting chocolate, a little smoky and rich, filled the kitchen. They loved how quick it was, and I loved that I didn’t have to turn on the oven or clean a bunch of dishes. It became our little secret for when we needed a sweet fix, fast and honest.

Ingredient breakdown: key components
- Dark chocolate: I prefer a good quality 70% cocoa bar; it melts smoothly and gives that rich, slightly bitter kick. Swap for milk chocolate if you want it sweeter and creamier, but you’ll lose some depth.
- Butter: Unsalted, ideally European-style for a silkier texture. If you only have margarine, it’s okay but expect a slightly different mouthfeel and less depth of flavor.
- Sweetened condensed milk: This is the glue that keeps everything fudgy and sweet. For a dairy-free twist, try coconut condensed milk—adds a subtle coconut aroma and a hint of tropical creaminess.
- Vanilla extract: A splash enhances the chocolate’s richness. Skip it if you’re out, but a pinch of instant coffee powder can boost the chocolate flavor instead.
- Nuts (optional): Toasted almonds or walnuts add crunch and flavor. If allergies are a concern, shredded coconut or dried fruit can be nice alternatives, bringing their own chewy or chewy textures.
- Salt: Just a pinch to heighten the chocolate’s intensity. If you’re avoiding salt, you can omit it, but the flavor might feel a touch muted.
- Optional toppings: Sprinkles, sea salt flakes, or extra melted chocolate. These give your slice a personal touch—try crunchy sea salt for contrast or a drizzle of white chocolate for visual flair.

Step-by-step guide to no bake chocolate slice
- Gather all ingredients and equipment. Line a 20x20cm (8×8 inch) baking pan with parchment paper for easy removal.
- Break the dark chocolate into small pieces. Use a heatproof bowl to melt the chocolate and butter together over a double boiler or in short bursts in the microwave (about 30 seconds each, stirring in between). Keep an eye on it to prevent burning—look for a glossy, smooth mixture with no lumps.
- Once melted, stir in the sweetened condensed milk and vanilla extract until well combined. The mixture should be thick, shiny, and oozy with a fragrant chocolate aroma.
- Pour the hot, glossy chocolate mixture into the prepared pan. Use a spatula to spread evenly, smoothing the surface with gentle taps. If it’s too thick to spread, warm it slightly again or stir vigorously.
- Sprinkle toasted nuts or toppings over the surface if you like. Press them lightly into the chocolate for better adhesion.
- Place the pan in the fridge and chill for at least 2 hours, or until the slice is firm and set. If rushing, pop it in the freezer for about 1 hour, but avoid freezing it solid as it can become brittle.
- Once firm, lift the slice out of the pan using the parchment paper. Cut into squares or rectangles with a sharp knife. Wipe the knife clean after each cut for neat pieces.
- Serve immediately for a fudgy texture or store in an airtight container in the fridge for up to 5 days. For longer storage, freeze for up to a month, wrapping tightly in foil or plastic wrap.
Chill the slice in the fridge for at least 2 hours or until firm. Slice into squares using a sharp knife, wiping it clean between cuts. Serve directly or store in an airtight container in the fridge for up to 5 days.
