Twix lovers, this one’s for you! Buttery shortbread, gooey caramel, and a fudgy brownie topping all stacked into one irresistible bar. These Twix brownies are everything you love about the candy, but better.
Millionaires shortbread is a longtime favorite of mine, so adding a rich brownie layer on top was the most obvious, and delicious, upgrade.
Recreating the beloved layers of a classic Twix bar, these Twix bar brownies feature a buttery shortbread base, a soft, chewy caramel filling, and a rich chocolate topping. Every texture and decadent flavor you crave, all in one irresistible bar. For best results, be sure to review the full recipe details in the card below.
BAKING TIP: When cooking the caramel, pull it off the heat the moment it still looks slightly too thin. It will continue to thicken as it cools, so you’ll end up with the perfect consistency without overcooking.
Cream the butter, sugar, and salt until smooth, then gradually mix in the self-rising flour until a dough forms. Press the dough evenly into a greased, parchment-lined baking pan, prick with a fork, and bake at 350°F/180°C (conventional oven) for 20 minutes until lightly golden. Set aside to cool.
Melt the butter in a saucepan, then add the condensed milk and brown sugar, stirring constantly over low heat until the sugar dissolves. Increase the heat slightly and bring the mixture to a boil, stirring continuously with a whisk for about 10 minutes until thickened.
Remove from heat while still slightly runny (it will set as it cools). Pour over the cooled shortbread layer, and chill briefly until firm.
TIP: Be careful not to cool the filling in the fridge for too long as it will harden too much.
Gently melt the butter, both sugars, chocolate, and syrup in a saucepan over low heat, stirring until smooth (the sugar doesn’t need to fully dissolve).
Let the mixture cool to room temperature, then mix in the egg and vanilla on low speed until combined. Add the flour, cocoa powder, and baking powder, mixing on low just until incorporated (don’t overmix).
Pour brownie batter over the chilled caramel layer and bake at 375°F/190°C (conventional oven) for 15 minutes. Cool completely in the pan before slicing.
Store these candy-inspired brownies (covered tightly with foil) in an airtight container at room temperature for up to a week.
Do not store the millionaire’s shortbread brownies in the refrigerator, as the caramel will become very hard and difficult to slice and bite through.
Yes you can freeze millionaires brownies. Properly wrap in plastic wrap to store in a freezer container for up to 3 months.

Like other regular brownies, I’ve used an 8×8 inch/20×20 cm square baking pan for this Twix-inspired brownie recipe. It creates the perfect size fudgy brownies and the right doneness with the baking time in the recipe below.
Instead of being a finger-shaped candy bar encased in chocolate, these are baked as a single, sliceable tray of brownies, so you get all the flavors and textures of a Twix in a fudgy, handheld square rather than a chocolate-coated stick.
Absolutely! You can use a store-bought caramel sauce as long as it is firm enough (not runny). Or you can use dulce de leche as a gooey caramel spread.
Don’t store these Twix brownies in the fridge. The caramel filling becomes very hard and difficult to slice neatly. I always keep these brownies at room temperature and use a large, sharp knife.
For extra clean cuts, you can run the knife under hot water, dry it, and then slice. The knife will glide right through.
Caramel filling that is cooked a little too long or at too high a temperature will turn hard. Cooking times can vary depending on your pan and stove. It’s best to stop just before it seems thick enough. Keep in mind that caramel will firm up more as it cools.
Yes! If shortbread cookies aren’t your thing, feel free to swap it out. A sugar cookie base works beautifully, or you can use crushed store-bought cookies mixed with melted butter. You might need to play around with the amounts, but I’d love to hear how it goes!
