The story behind this recipe

This recipe came together one rainy afternoon when I needed a sweet fix but didn’t want to turn on the oven. I remembered my grandmother’s quick chocolate bars, which she’d make with whatever was in the pantry. That simple memory sparked the idea to create a no-bake version that’s easy to whip up and reliably delicious.
Over the years, I’ve added my own tweaks—more butter, a sprinkle of sea salt, a dash of vanilla—to make it feel more indulgent. It’s become my fallback for unexpected guests or when I just need something sweet and satisfying, fast. There’s a real comfort in knowing I can make this in minutes, with ingredients I always keep on hand.
heading: The story behind this recipe

Ingredient breakdown: key components

Dark chocolate: I love the intense, slightly bitter flavor that melts smoothly, coating every bite. If you prefer milder sweetness, try milk chocolate instead.
Butter: It gives the slice that rich, velvety texture. You can swap in coconut oil for a dairy-free version, but it’ll have a slightly different melt and richness.
Biscuits: I use plain digestives—they add crunch and a buttery note. Graham crackers work well too, especially if you like a hint of sweetness.
Sweetener: I usually stick to golden syrup or honey for a sticky, glossy finish. Maple syrup can be a good swap if you want a subtle, smoky sweetness.
Vanilla extract: Just a splash brightens everything up. If you don’t have vanilla, a pinch of cinnamon or a dash of coffee can add depth.
Sea salt: A tiny pinch enhances all the flavors and balances the sweetness. If you don’t have sea salt, regular table salt works, just don’t overdo it.
Optional toppings: Chopped nuts or dried fruit can add texture and contrast. I love a handful of toasted almonds for a nutty punch.

Notes for ingredient swaps

Dairy-Free: Swap butter for coconut oil or margarine. It may add a slightly different melt and coconut aroma.
Chocolate: Use dairy-free dark chocolate or cacao nibs for a richer, more intense cocoa flavor. Adjust sweetness if needed.
Biscuits: Gluten-free digestives or graham crackers work well. For a nutty crunch, try crushed nuts pressed into the base.
Sweetener: Honey or maple syrup can replace golden syrup, but expect a slightly different texture and flavor profile.
Vanilla: Almond extract or vanilla bean paste can add a different aromatic note if you don’t have vanilla extract.
Salt: Sea salt flakes add a subtle crunch and flavor boost. Regular table salt is fine if used sparingly.
Toppings: Chopped nuts, dried fruit, or coconut flakes can be added on top for extra texture and contrast.

Step-by-step guide to no bake chocolate slice

Gather your equipment: a 20x20cm (8×8 inch) baking tray, a saucepan, a mixing spoon, and parchment paper. Line the tray with parchment for easy removal.
Melt the butter and chocolate: place them in the saucepan over very low heat (around 50°C / 122°F). Stir gently until smooth and shiny. This should take about 3-5 minutes. Keep an eye to avoid scorching or burning; if the mixture smells smoky or starts to crackle, remove from heat immediately.
Prepare the biscuit base: roughly crush the biscuits into small, irregular pieces. You can do this by hand or in a sealed bag with a rolling pin. Aim for a mix of fine crumbs and some larger bits for texture.
Combine ingredients: pour the crushed biscuits into the melted chocolate and butter mixture. Add the vanilla extract and a pinch of sea salt. Mix thoroughly until all the biscuit pieces are coated and the mixture is cohesive. It should be sticky and glossy.
Transfer to tray: spoon the mixture into the prepared tray. Use the back of a spoon or a spatula to press it down evenly, creating a smooth top. Press firmly but gently—don’t crush the biscuits too flat, or you’ll lose the crunch.
Set in the fridge: cover loosely with plastic wrap or foil. Chill for at least 2 hours, or until firm and set. For a quicker set, you can place it in the freezer for about 1 hour, but keep an eye on it to prevent freezer burn.
Slice and serve: once set, lift the slice out of the tray using the parchment paper. Use a sharp knife to cut into squares or rectangles. For clean cuts, wipe the blade between slices. Serve directly or store in an airtight container.

Cover the tray loosely with plastic wrap or foil and refrigerate for at least 2 hours until firm. Slice into squares, then serve directly from the fridge or at room temperature for a softer bite.
