Tips & Notes

Pro tips

Drizzle the condensed milk in a thin stream or grid pattern over the batter so it distributes evenly and caramelizes throughout.
Use freshly brewed or cooled coffee to avoid lumps in the batter; it deepens chocolate flavor without making the brownies taste like coffee.
Don't overbake—pull from the oven when the center still jiggles slightly; carryover heat will firm them up as they cool.
Let brownies cool completely before cutting for clean edges and to let the dulce de leche set.

Substitutions

Vegetable oil → melted butter or coconut oil (note: butter will add richness; coconut oil keeps them fudgier)
Coffee → hot water (note: omit coffee entirely if you prefer pure chocolate without depth)
Sweetened condensed milk → caramel sauce or dulce de leche (note: drizzle on top after baking rather than mixed in for cleaner swirl)

Storage & make-ahead

Store in an airtight container at room temperature for up to 3 days or refrigerate for up to 5 days; microwave briefly before serving to restore fudginess.

Common Questions

Can I make this without coffee?

Yes. Coffee enhances chocolate depth but is optional. Replace with water or omit entirely—the brownies will still be sweet and fudgy.

How much dulce de leche will the condensed milk make?

2 tbsp of sweetened condensed milk will partially caramelize into dulce de leche during baking, creating pockets of sweetness. For more caramel flavor, drizzle an additional 1–2 tbsp on top after baking.

What's the best way to tell when they're done?

Bake until a toothpick inserted into the cake (not the wet dulce de leche) comes out with a few moist crumbs. Overbaking dries them out.

Can I use homemade dulce de leche instead?

Yes. Swirl homemade dulce de leche into the batter or drizzle on top before baking for deeper caramel flavor.

How should I store these?

Keep in an airtight container at room temperature for up to 3 days. Refrigerate for up to 5 days. Reheat briefly in the microwave before serving if desired.
