This no-bake Millionaire’s Shortbread stacks a buttery cookie base, quick condensed milk caramel, and a layer of chocolate on top. Just five ingredients, no oven. These bars slice like a dream, and vanish just as fast.
Ingredient notes and substitutions
Listed below are notes for the main ingredients. You’ll find all other details and exact amounts in the recipe card at the end of this post.
Shortbread: Store-bought or homemade shortbread both work. Or use plain, graham or digestive cookies, nothing filled or flavored. Crush in a food processor or bash in a zip-top bag with a rolling pin. The crumbs should be fine and sandy so they hold together.
Butter: Used in both the base and caramel. I used salted. If using unsalted, add ⅛ teaspoon fine salt when the butter and sugar go into the pan.
White sugar: Use regular granulated sugar. Brown sugar has more molasses, which can make the caramel heavier and slightly grainy.
Sweetened condensed milk: Make sure it’s sweetened condensed milk — not evaporated. They’re not the same thing.
Chocolate: I used semi-sweet (40%) to balance the sweetness. Good-quality chips or chopped chocolate bars work. Regular eating chocolate is fine if it melts well. Some brands add stabilizers that don’t melt smoothly.

Shortbread layer
- Add crushed shortbread cookies to melted butter in a saucepan. Stir to combine until the mixture looks like wet sand.
- Spoon the cookie mixture into a lined 8-inch (20 cm) square pan.
- Press the crumbs firmly into an even layer using the back of a spoon. Refrigerate while you prepare the caramel.
Caramel layer
- Place the butter and sugar in a saucepan over medium-low heat. Once melted and bubbling, pour in the sweetened condensed milk.
- Stir constantly for 4–5 minutes until the caramel thickens and coats the spoon, it should still be pourable.
Some golden or darker flecks in the caramel are normal. They’re just bits of cooked condensed milk that catch on the pan. It’s fine if a few get poured over the base in the next step, just don’t scrape the bottom of the pan.
- Immediately pour the hot caramel over the chilled base. Don’t let it sit in the saucepan, it starts to set as it cools.
- Use the back of a spoon to spread the caramel into an even layer. Refrigerate for at least 45 minutes, or until the caramel is firm to the touch and no longer sticky.
Chocolate layer
- Pour the melted chocolate over the chilled caramel layer.
- Tilt the pan or use the back of a spoon or offset spatula to spread it evenly to the edges.
- Let chocolate set at room temp, not in the fridge. Chilling too soon can make the top dull or cause cracks when slicing.
- Room temp makes slicing easier — no shattered tops.
- Chill after for storage, but let bars sit out before serving. If water droplets form, they’ll dry off on their own.
What chocolate to use (and what to avoid)
The chocolate’s the crowning glory, but not all types melt the same. Use this quick guide to help you pick the right kind and skip the grainy mess.
| Melts smoothly | Does not melt well |
|---|---|
| Baking chocolate (bars or blocks) | Candy bars with added oils or fillings |
| Chocolate chips labeled meltable or baking | Compound or “chocolatey” coating |
| High quality chocolate bars with cocoa butter | Chocolate made with palm oil or other vegetable fats |
| Semi-sweet or bittersweet around 40-60% | White chocolate with low cocoa butter content |
Two easy ways to melt chocolate smoothly
Make sure all bowls and utensils are completely dry before melting, even a small amount of water can make the chocolate clump or turn grainy.
- Microwave method: Add chopped chocolate to a dry, microwave-safe bowl. Heat in 30-second bursts, stirring between each round, until smooth.
- Double boiler method: Place a heat-safe bowl over a pot of gently simmering water (the bowl should sit above the water without touching it). Stir until fully melted.
Storage
- Room temperature: Store the sliced bars in an airtight container for up to 3 days. Best if your kitchen isn’t too warm or humid.
- Fridge: Keeps well for up to 1 week. Before serving, let the bars sit at room temperature for 10–20 minutes. The chocolate will soften slightly, and any tiny water droplets on the surface will dry up on their own.
- Freezer: Freeze for up to 2 months. Use parchment between layers. Thaw at room temperature before serving.

Recipe
No-Bake Millionaire’s Shortbread
Shortbread Base
- 2½ cups (250 g) crushed shortbread (can use graham crackers or digestive cookies)
- ⅓ cup (75 g) melted butter
Caramel Filling
- 7 Tablespoons (98 g) butter
- ¼ cup (50 g) white granulated sugar
- 14 oz (395 g) sweetened condensed milk
Chocolate Topping
- 1 cup (175 g) chopped chocolate (baking chips, meltable bars, or any good-quality chocolate)
Make the shortbread base
- Add the crushed shortbread to a mixing bowl. Pour in the melted butter and stir until evenly combined.
- Press the mixture firmly into a lined 8-inch (20 cm) square pan. Refrigerate while you prepare the caramel.
Make the caramel filling
- Place the butter and sugar in a medium saucepan over medium-low heat.
- Heat gently until the butter melts and the mixture starts to bubble. Add the sweetened condensed milk and stir constantly.
- Cook for 4–5 minutes, or until the caramel thickens, coats the spoon, and is still pourable. Immediately pour the hot caramel over the chilled base and spread evenly.
- Refrigerate for 45 minutes, or until the caramel is set and firm to the touch.
Add the chocolate topping
- Melt the chocolate in 30-second microwave bursts or over a double boiler. Pour over the chilled caramel and tilt the pan to spread evenly.
- Let set at room temperature, do not refrigerate.
Chocolate topping tips
- Let chocolate set at room temp, not in the fridge. Chilling too soon can make the top patchy or cause cracks when slicing.
- Chill after for storage, but let bars sit out before serving. If water droplets form, they’ll dry off on their own.
Crush into fine, sandy crumbs using a food processor or a zip-top bag and rolling pin.
2. Butter: Salted or unsalted both work. If using unsalted, add a pinch (⅛ tsp) of salt when making the caramel.
3. Sugar: Stick with white granulated sugar for the best caramel texture.
4. Sweetened Condensed milk: Use sweetened condensed milk – not evaporated.
5. Chocolate: Semi-sweet (~40%) balances the sweetness of the caramel. Use meltable bars, chips, or chocolate without added oils or fillers. For melting, see: Two Easy Ways to Melt Chocolate
