If you want the richest, most over-the-top brownie dessert you can stack in a 9×13 pan, these Ooey Gooey Millionaire Brownies are exactly what you should bake next. You start with a buttery shortbread crust, add a thick, fudgy brownie layer, pour on lush dulce de leche, and finish with silky chocolate ganache and crunchy pecans for a true “millionaire” mash-up of flavors and textures.
Why you’ll obsess over these brownies
You’re basically combining three iconic desserts in one: buttery shortbread, fudgy brownies, and millionaire-style caramel bars. The shortbread base gives structure and a tender, crumbly bite underneath all that gooey richness, while the brownie layer bakes up thick and fudgy thanks to a boxed mix (you still get from-scratch vibes because of the other layers). Then you pour on ready-made dulce de leche for velvety caramel and cap everything with glossy ganache and toasted pecans for crunch and contrast. Chilling the pan turns all those layers into neat, sliceable squares that still taste insanely gooey when brought to room temperature.
