This no bake chocolate slice is my go-to when I need something sweet but don’t want the fuss of turning on the oven. It’s a bit like a grown-up version of a childhood treat, with that rich, fudgy texture that melts on your tongue. Plus, it’s so quick to throw together, you can whip it up in moments, even on your busiest days.
What I love most is how forgiving it is—no precise measuring, no complicated techniques. Just good ingredients, a little patience, and a moment of quiet to enjoy the process. It’s the kind of dessert that feels like a warm hug, especially when shared with friends or family on a lazy weekend or after a hectic day. Sometimes, the simplest recipes carry the most comfort.
This recipe is inspired by my grandmother’s quick fix for rainy days, when chocolate and comfort are all I crave but I have no energy for baking. It’s a reminder that sometimes, the simplest ingredients and a bit of patience can turn into something unexpectedly satisfying.
The story behind this recipe
This recipe came together on a rainy afternoon, when I wanted something sweet but didn’t want to turn on the oven. I remembered my mum making something similar with just a few pantry staples, and I thought, why not make it my own? It’s become a bit of a ritual, especially when I need a quick fix for chocolate cravings or want to bring a treat to friends without fussing over it. The smell of melting chocolate and toasted biscuits always takes me back to lazy weekends and messy kitchen counters filled with laughter.
Ingredient breakdown: key components
- Dark chocolate: I love using a good-quality dark chocolate, it gives that rich, deep flavor. You can swap for semi-sweet if you prefer milder, but avoid overly sweet chocolates that drown out the cocoa notes.
- Butter: I melt butter until it’s silky to help everything bind smoothly. For a dairy-free version, try coconut oil — it adds a slight tropical aroma and keeps the texture creamy.
- Biscuits: I prefer plain malt or digestive biscuits for a subtle crunch. If you want a nuttier flavor, crushed graham crackers work well, or for a gluten-free twist, try crushed rice cereal.
- Sweetener: I usually stick with a touch of honey or golden syrup for a mellow sweetness. Maple syrup can add a smoky undertone, while agave keeps things neutral if you’re watching sugar.
- Vanilla extract: Just a splash lifts the chocolate flavor. For an extra layer, a hint of espresso powder amplifies richness, but skip it if you want a straightforward chocolate hit.
- Salt: A pinch of sea salt balances the sweetness and enhances the chocolate. If you’re feeling adventurous, a tiny sprinkle of smoked salt adds a surprising depth.
- Optional toppings: I often sprinkle chopped nuts or dried fruits on top before chilling. They add texture and bursts of flavor, but you can skip if you want a pure, fudgy slice.

Notes for ingredient swaps
- Dairy-Free: Swap butter for coconut oil — it melts just as smoothly and adds a subtle tropical aroma, but expect a slightly different richness.
- Chocolate: Use milk chocolate if you prefer a sweeter, creamier texture, though it will be less intense and fudgy than dark chocolate.
- Biscuits: Gluten-free digestives or graham crackers work well for a different crunch and flavor; crushed rice cereal is a neutral, allergy-friendly option.
- Sweetener: Honey or golden syrup can replace sugar or agave for a mellow sweetness, but note they add moisture and a slight flavor change.
- Add-ins: Nuts or dried fruits can be omitted or swapped with seeds or crushed pretzels for varied texture and flavor bursts.
- Salt: Regular sea salt can be replaced with smoked salt for a surprising depth, just use sparingly to avoid overpowering the chocolate.
- Toppings: Chopped nuts, dried fruits, or sprinkles can be customized or skipped entirely for a cleaner, more straightforward slice.
Equipment & Tools
- Baking dish: Holds the mixture and shapes the slice.
- Saucepan: Melts the chocolate and butter gently.
- Mixing bowl: Combines biscuits and melted chocolate.
- Spatula: Stirs and presses the mixture into the dish.
- Sharp knife: Cuts the set slice into portions.
Step-by-step guide to making no bake slice
- Gather your equipment: a rectangular baking dish (20x10cm or 8×4 inches), a saucepan, a mixing bowl, and a spatula. Line the dish with baking paper for easy removal.
- Melt the butter and dark chocolate together: place in a saucepan over low heat (about 50°C / 122°F). Stir occasionally until smooth and shiny, about 3-4 minutes. Smell that rich cocoa aroma as it melts.
- In a large mixing bowl, crush your biscuits roughly — aim for uneven pieces for texture. Pour the melted chocolate mixture over the biscuits and stir quickly to coat everything evenly. It should look fudgy and glossy.
- Transfer the mixture to your prepared dish. Use the spatula to press it down firmly, smoothing the top. The surface should look even, with no gaps or air pockets.
- Refrigerate uncovered for at least 2 hours, or until firm. If in a hurry, place in the freezer for 30-45 minutes, but avoid rushing the setting process to prevent cracking.
- Once set, remove from the fridge and let sit at room temperature for 5 minutes. Slice into bars or squares with a sharp knife. Tap the knife gently to avoid crumbling.
- Finish by sprinkling with chopped nuts or dried fruit if you like. Serve directly from the dish or plate on a pretty tray for sharing.
Refrigerate uncovered until firm, about 2 hours. Slice with a warm knife for clean edges. Serve immediately or store in an airtight container in the fridge for up to 3 days.

- OVER-TORCHED the chocolate → Remove from heat immediately if smell turns burnt.
- MISSED the chill time → Allow at least 2 hours in fridge for proper setting.
Quick Fixes and Pantry Swaps
- When chocolate seizes, splash in a teaspoon of warm milk to loosen it.
- If the slice cracks on slicing, briefly warm the knife for a cleaner cut.
- DUMPED too much butter? Chill the mixture briefly to firm it up before pressing.
- Over-melted chocolate? Patch with a spoonful of cocoa powder and mix well.
- When mixture feels too dry, add a splash of hot water or extra melted butter for gloss.
Prep, store, and reheat tips
- Prepare the mixture in advance: melt chocolate and butter, crush biscuits, and mix everything together up to 24 hours ahead. Keep the mixture covered in the fridge, so it stays fresh and fragrant.
- Store the assembled slice: once pressed into the dish, cover with plastic wrap and refrigerate for up to 3 days. The flavors deepen and the texture firms up nicely during this time.
- Shelf life: the no bake chocolate slice keeps well for 3 to 4 days in the fridge. After that, the biscuits may soften too much, and the chocolate could lose some of its shine.
- Reheating or serving tips: there’s no need to reheat. Serve straight from the fridge for that firm, fudgy bite. If you want it softer, let it sit at room temperature for 5-10 minutes and note the aroma will warm and intensify.
