White Chocolate Peanut Butter Truffle Recipe

Mars Bars already have everything going for them: caramel, nougat, and silky milk chocolate. But when you turn them into a creamy, boozy cocktail? That’s when magic happens. This Mars Bar Dessert Cocktail is like drinking a chocolate bar milkshake—smooth, rich, and a little bit naughty.

It’s the kind of indulgent drink you make when you want to skip dessert altogether, or when you’re entertaining and need a show-stopping treat in a glass. One sip and you’ll understand why this cocktail is about to become your new guilty pleasure.

Why You’ll Love It

• Tastes just like a Mars Bar – but with a boozy grown-up kick.

• Quick to make – blend and pour, no fuss.

• Perfect for dessert lovers – doubles as a drink and a sweet treat.

• Customisable – adjust the liqueurs for more chocolate, caramel, or creaminess.

Ingredients (serves 2)

• 2 x fun-sized Mars Bars, chopped

• 60ml (2 oz) Baileys Irish Cream

• 60ml (2 oz) Kahlúa (coffee liqueur)

• 30ml (1 oz) Butterscotch schnapps (for caramel flavour)

• ½ cup heavy cream (or vanilla ice cream for a milkshake version)

• 1 tbsp chocolate syrup

• Ice cubes

• Extra chocolate syrup and whipped cream (optional, for garnish)

• 1 fun-sized Mars Bar, sliced (for garnish)

Method

Step 1 – Prep the glasses
Drizzle chocolate syrup around the inside of two martini or dessert glasses. Pop them into the fridge to chill while you make the cocktail.

Step 2 – Blend it all together
In a blender, combine chopped Mars Bars, Baileys, Kahlúa, Butterscotch schnapps, cream, chocolate syrup, and ice cubes. Blend until smooth and creamy.

Step 3 – Pour and garnish
Divide between the chilled glasses. Top with whipped cream, drizzle of chocolate syrup, and a slice of Mars Bar perched on the rim or skewered on a cocktail stick.

Step 4 – Serve immediately
This cocktail is rich and indulgent—best enjoyed straight away while it’s frosty and fresh.

Variations to Try

• Frozen Mars Cocktail – blend with extra ice for a thicker, slushy-style drink.

• Extra Caramel Hit – add a swirl of caramel sauce in the glass before pouring.

• Lighter Version – swap cream for milk or almond milk for a thinner sip.

• Over-the-Top Dessert – serve with a scoop of vanilla ice cream right on top.

When to Serve

This Mars Bar Dessert Cocktail is perfect for:

• Girls’ nights in with snacks and laughter.

• A cheeky dessert replacement when you want chocolate and booze.

• Date nights at home (bonus points if you share the last Mars Bar).

• Festive parties or special occasions where indulgence is the goal.

Mars Bars have a way of making us feel nostalgic and a little bit cheeky—and this cocktail delivers both. Rich, chocolatey, caramel-y, and perfectly boozy, it’s dessert and drink rolled into one.

So if you’ve ever found yourself sneaking a mini Mars Bar from the pantry, imagine blending that same joy into a glass with a splash of liqueur. Trust me: it’s a recipe worth keeping.
