I have to confess: I make these Millionaire Shortbread Cups whenever I want to feel like a domestic wizard without breaking out a chemistry set. I mean, three layers — a buttery shortbread base, gooey brown-sugar caramel, and a glossy chocolate hat — all in one bite? Ridiculously satisfying. Warning: your kitchen will smell like caramel happiness and you will eat at least one off the cooling rack. I promise these feel fancy, but they behave like a very cooperative dessert. Perfect for dunking, gifting, or hiding in the back of the fridge and pretending you forgot about them (I’ll never tell).

Ingredients
For the Main Dish:
- 1 1/2 cups all-purpose flour
- 1/2 cup powdered sugar
- 3/4 cup (12 tbsp) unsalted butter, cold and cubed
- Pinch of salt
- 1 cup packed light brown sugar
- 6 tbsp unsalted butter (for caramel)
- 1/2 cup heavy cream
- Pinch of salt (for caramel)
- 1 tsp vanilla extract
- 8 oz semi-sweet chocolate (about 1 1/3 cups chips)
- 1 tbsp coconut oil or neutral oil (optional, for shine)
- Flaky sea salt or chopped toasted pecans, for garnish (optional)
For the Sauce / Garnish (if applicable):
- Optional drizzle: 2 tbsp melted chocolate or 1 tsp cocoa powder mixed into 1 tbsp cream for a thicker drizzle
How I Make It
Step 1:
I preheat the oven to 350°F. I pulse the flour, powdered sugar, and a pinch of salt in a bowl, then quickly rub in the cold butter with my fingers until the mixture looks like coarse crumbs. It smells faintly buttery and feels cool between my fingers. I press the dough into a greased 12-cup muffin tin, pushing up the sides to form little cups. I prick each bottom a couple of times with a fork to avoid bubbling.
Step 2:
I bake the shortbread for 18–20 minutes until the edges turn a soft golden color. You’ll see tiny cracks and smell that warm, buttery aroma — that’s your cue. Let the cups cool in the tin for about 10 minutes, then transfer them to a wire rack so they stop steaming and stay crisp.
Step 3:
While the crust cools, I make the caramel. I combine the brown sugar, 6 tbsp butter, and 1/2 cup heavy cream in a heavy saucepan over medium heat. I stir constantly until the sugar dissolves, then let it bubble gently for about 6–8 minutes until thick and glossy. Watch the color turn a deep golden brown and breathe in that toasty, buttery smell — irresistible. Stir in the vanilla and a pinch of salt. If the caramel looks too thin, simmer another minute; it will thicken as it cools.
Step 4:
I spoon about 1–2 tablespoons of warm caramel into each shortbread cup, spreading it so it reaches the edges but doesn’t overflow. Then I chill the pan in the refrigerator for 15–20 minutes so the caramel firms up and stops oozing everywhere.
Step 5:
Finish with the chocolate: I melt the 8 oz chocolate with 1 tbsp coconut oil in 20–30 second bursts in the microwave, stirring between bursts until smooth and glossy. I pour or spoon the melted chocolate over each caramel-filled cup and tap the pan on the counter to level the tops. Sprinkle flaky sea salt or chopped pecans right away if you like. Chill until the chocolate sets, about 20–30 minutes. When you bite one, listen for that satisfying little crack of chocolate and enjoy the gooey caramel pull.
Pro Tips
- Use a heavy saucepan for the caramel so it heats evenly and won’t scorch. Stir continuously near the end.
- Press the shortbread securely into the tin so it holds the caramel. If edges crack, press crumbs back together with the bottom of a spoon.
- If your caramel gets grainy, whisk in 1–2 tbsp hot water and simmer gently to smooth it out.
- For perfectly even cups, use an ice cream scoop to portion the caramel and chocolate.
Common Mistakes to Avoid
- Skipping preheating: Classic rookie move. It changes texture and bake time.
- Overmixing: Leads to dense or chewy results. Mix until just combined.
- Guessing cook time: Always use visual cues or a timer, not just vibes.
- Overcrowding pans: Give your food some breathing room to crisp properly.
Alternatives & Substitutions
- Use a gluten-free 1:1 flour blend for a gluten-free crust; texture will stay tender but might be slightly crumbly.
- Swap heavy cream for full-fat canned coconut milk to make the caramel dairy-free; expect a subtle coconut flavor.
- Replace chocolate with chopped milk chocolate or dark chocolate — darker gives less sweetness and more snap.
- Shortcut: Use store-bought dulce de leche spread in place of making caramel; skip cooking time and get consistent results.
Variations & Tips
- Make mini versions in a mini muffin tin for bite-sized party treats.
- Add a pinch of cayenne or cinnamon to the caramel for a warm, spicy kick.
- Stir chopped toasted pecans or almonds into the caramel for extra crunch.
- Mix a teaspoon of orange zest into the chocolate for a chocolate-orange twist.
- Top with crushed pretzels for a sweet-salty treat that kids and adults both love.
FAQ (Frequently Asked Questions)
- Can I make this ahead of time?
- Yes! Store the finished cups in an airtight container in the refrigerator for up to 5 days. Bring to room temperature for 15–20 minutes before serving so the caramel softens.
- Can I double the recipe?
- Sure thing. Use two muffin tins or make two batches. Baking time for the shortbread stays the same; just watch the edges on each pan as oven hotspots vary.
- Can I substitute butter with oil?
- Technically yes, but you’ll miss that buttery magic. Use 3/4 the amount of oil and know the crust will be slightly less crisp and more tender.
- How do I know it’s done?
- The shortbread looks lightly golden at the edges and smells nutty-buttery. The caramel will thicken and coat a spoon; the chocolate should snap and look glossy when set.
- What if I don’t have ingredient X?
- Out of heavy cream? Use full-fat coconut milk or a little extra butter plus milk. No powdered sugar? Use granulated sugar for the crust (pulse until fine) — slightly different texture but still tasty.
How I Like to Serve It
I serve these at holiday parties on a pretty platter, but honestly I mostly make them for cozy nights with tea or coffee. They pair beautifully with black coffee, a big glass of cold milk, or a nutty brown ale for grown-up gatherings. They fit fall baking, holiday cookie boxes, or an afternoon pick-me-up when you want something truly decadent.
Notes
- Store in an airtight container in the fridge up to 5 days; for longer storage freeze in a single layer on a sheet, then stack with parchment between layers in a freezer-safe bag for up to 2 months.
- If you warm frozen cups, thaw in the fridge overnight and bring to room temperature before serving.
