Decadent Fudge Brownies Made with Sweetened Condensed Milk

These sweetened condensed milk brownies are rich, fudgy, and perfectly sweet. This one-bowl brownie recipe is easy to make and utterly irresistible.

I’m a chocolate lover through and through—dark, deeply flavored, and extra fudgy. Brownies are one of my favorite desserts, so I hold them to high standards. A dry, cakey brownie won’t do; these sweetened condensed milk brownies are the opposite: gooey, intensely chocolatey, and studded with semi-sweet chips.

If you have a spare can of sweetened condensed milk and want a simple, show-stopping dessert, condensed milk brownies are a perfect choice. They bake up fast, require just one bowl, and deliver a decadent, fudgy texture every time.

Why you’ll love it

• One-bowl recipe – Everything comes together in one bowl and it only takes minutes to prepare before baking.
• Ultra fudgy – These brownies emphasize richness and gooeyness over a cakey crumb, thanks to the sweetened condensed milk and chocolate.
• Customizable – Add nuts, candy, or swirls of peanut butter or jam to make them your own.

Ingredients

Butter – Unsalted butter is preferred for baking so you can control salt levels. If you use salted butter, omit added salt.

Dark chocolate – Use good-quality dark chocolate or chips for depth of flavor. This ingredient makes a big difference.

Sugar – A little sugar helps balance the chocolate, since sweetened condensed milk already adds sweetness.

Sweetened condensed milk – This creates an ultra-rich, tender, fudgy brownie. Be sure to use sweetened condensed milk, not evaporated milk.

Dark cocoa powder – Dutch-processed or dark cocoa adds color and chocolate intensity. I use Hershey’s dark cocoa.

Eggs – Large eggs add structure and richness.

All-purpose flour – Brownies need only a small amount of flour; use more and they’ll become cakier. For gluten-free, substitute a 1:1 gluten-free baking flour.

Baking powder – Gives a slight rise and a nicely cracked top.

Salt – A pinch enhances and rounds the chocolate flavors.

Chocolate chips – Semisweet chips give extra pockets of melty chocolate; you can swap or add other mix-ins as desired.

How to make condensed milk brownies

Preheat the oven to 350°F (175°C) and prepare an 8×8 inch baking pan by spraying it with nonstick cooking spray.

Melt butter & chocolate

In a microwave-safe bowl, combine the butter and dark chocolate. Microwave in 20-second intervals, stirring between each, until the mixture is completely melted and smooth.

Add the sugar

Stir in the sugar, sweetened condensed milk, and dark cocoa powder until fully incorporated and glossy.

Add the eggs

Lightly whisk the eggs in a small bowl, then fold them into the chocolate mixture. Whisking them first prevents overmixing the batter.

Avoid overmixing—too much mixing can add air and produce a cakier brownie.

Add the dry ingredients

Gently fold in the flour, baking powder, and salt until just combined, then stir in the chocolate chips.

Bake the brownies

Pour the batter into the prepared pan, smooth the top, and sprinkle with a few extra chocolate chips. Bake for about 30 to 32 minutes. The edges should be set while the center remains slightly underdone and jiggly—this ensures a fudgy texture once cooled.

Allow the brownies to cool completely before slicing to get clean squares. Enjoy!

Variations & Substitutions

Toppings: Swirl peanut butter or raspberry jam into the batter before baking, or spread a ganache over cooled brownies.

Mix-ins: Replace or add to the chocolate chips with chopped nuts, white chocolate, crushed cookies, candy pieces, or M&M’s.

Gluten-free: Use a 1:1 gluten-free baking flour and gluten-free chocolate chips to make this recipe gluten-free.

Storage & Freezing

How to store brownies

Cool brownies to room temperature, then store in an airtight container. Keep them on the counter for up to 3 days or refrigerate for up to one week.

How to freeze brownies

Cut brownies into squares and freeze them individually on a tray until firm. Transfer frozen squares to a resealable bag and freeze for up to 3 months. Thaw at room temperature or warm briefly in the microwave.

Recipe Tips

• Don’t overbake. The center should still be slightly jiggly when you remove the pan; it will set as it cools.
• Cool before slicing. Cutting warm brownies often leads to messy, falling-apart pieces. Wait at least 30 minutes.
• Fudgier as they cool. Brownies firm up and become fudgier as they rest; if you prefer warm, serve immediately but expect looser slices.
• Avoid overmixing. Stir just until the dry ingredients are incorporated to keep the texture dense and fudgy.
