✓ Preheat oven to 350°F (175°C); line a 9‑inch square pan with parchment paper.

✓ Combine the brownie mix, vegetable oil, and eggs in a large bowl; stir until a smooth batter forms.

✓ Spread the brownie batter evenly in the prepared pan; bake for 10 minutes or until the edges begin to set.

✓ While the base bakes, beat softened cream cheese, sugar, and vanilla extract until light and fluffy; this should take about 2 minutes.

✓ Fold chopped Milky Way pieces into the cheesecake mixture; the pieces should remain distinct.

✓ Remove the pan from the oven; the brownie layer should be slightly firm but still soft in the center.

✓ Drop spoonfuls of the cheesecake mixture over the partially baked brownie; use a spatula to swirl gently, creating marbled ribbons.

✓ Drizzle caramel sauce over the top, allowing it to pool in some areas and trickle into others.

✓ Scatter chopped pecans across the surface; they should cover the pan evenly.

✓ Return the pan to the oven and bake for an additional 15‑18 minutes, or until the cheesecake edges are set and a toothpick inserted near the center comes out with a few moist crumbs.

✓ Do not overbake — this ensures the interior stays creamy and the caramel does not harden.

✓ Allow the brownie to cool in the pan for 20 minutes; this helps the layers firm up.

✓ Transfer the cooled slab onto a cutting board and lift using the parchment paper.

✓ Cut into twelve squares; each piece should display a dark chocolate top, swirls of caramel, and specks of pecan.

✓ Serve warm or at room temperature; a dollop of whipped cream adds a light contrast.

✓ Optional garnish: a light dusting of sea salt enhances the caramel’s sweetness.
