2-Ingredient Fudgy Brownies (Brownie Mix With Condensed Milk)
These brownies are the one I make when I need something ridiculously fudgy with almost zero effort. A box of brownie mix and a can of sweetened condensed milk are all it takes, no oil, no eggs, no measuring cups.
You get a dense, deeply chocolatey square with a shiny, crackly top and a center that stays soft for days. It’s the kind of dessert that feels like a happy accident that actually works.
Why This Hack Sticks Around
The condensed milk does all the heavy lifting here. It brings the moisture, the fat, and the sweetness, so you can skip the oil, water, and eggs the box usually calls for. That means zero measuring and one bowl to clean.
The texture lands somewhere between a classic brownie and a flourless chocolate cake. The edges set up chewy while the middle keeps an almost truffle-like softness. I keep this version around because it’s impossible to mess up, and the results are better than what I get following the box directions, honestly.
Ingredients
- 1 box (18.3 oz) brownie mix: any brand works; the fudgy styles with chocolate chips already in the mix are my go-to
- 1 can (14 oz) sweetened condensed milk: full-fat gives you the richest, silkiest texture
Variations
- Add a handful of chocolate chips: stir in ½ cup before baking for pockets of melted chocolate
- Swirl in ¼ cup peanut butter: dollop on top of the batter and drag a knife through it before it hits the oven
- Splash of vanilla or espresso powder: stir in 1 teaspoon vanilla or ½ teaspoon instant espresso to deepen the chocolate flavor
- Dairy-free version: use a dairy-free brownie mix and a can of coconut sweetened condensed milk

How to Make Brownie Mix Condensed Milk Brownies
Step 1: Mix the Batter
Preheat the oven to 350°F (175°C) and line an 8×8 inch square pan with parchment paper. Dump the entire box of brownie mix into a big bowl, then pour in the full 14-ounce can of sweetened condensed milk. Stir with a spatula for about 1 minute until a very thick, glossy batter forms. No dry pockets should be left, but do not overmix once it comes together.
Step 2: Bake the Brownies
Scrape the batter into the prepared pan and smooth the top with the back of a spoon. It will be stiff, so press it into the corners. Bake for 25 to 30 minutes. The edges will look set and start to pull away from the sides, while the center will still have a slight jiggle. You are looking for a glossy, crackled surface with no wet batter pooling.
Step 3: Cool and Slice
Let the brownies cool in the pan on a wire rack for at least 20 minutes before you even think about slicing. They will keep setting up as they cool, so that fudgy center becomes sliceable. Lift them out using the parchment overhang, cut them into 9 squares, and serve warm or at room temperature.
Tips for Extra-Fudgy Brownies
- Line the pan instead of greasing: Parchment slings make it easy to lift the whole block out with no sticking. No scraping, no broken corners.
- Check early if your oven runs hot: These brownies are done when a toothpick inserted two inches from the edge comes out with a few moist crumbs. If it comes out batter-wet, give it 3 more minutes and test again.
- Chill them for a clean cut: Pop the pan in the fridge for 30 minutes after cooling if you want perfectly clean, sharp squares.
- Dark metal pans bake faster: Reduce the time by 3 to 5 minutes to keep the center from drying out.
Bake times by pan and material:
| Pan size | Pan material | Bake time |
|---|---|---|
| 8×8 inch | Metal | 25 to 30 mins |
| 8×8 inch | Glass | 30 to 35 mins |
| 9×13 inch (double recipe) | Metal | 20 to 25 mins |
Keeping Leftovers Fresh
- Refrigerate: Store the brownies in an airtight container in the fridge for up to 5 days. Their texture gets even denser when cold.
- Reheating: Zap a square in the microwave for 10 to 15 seconds for that just-baked, gooey warmth.
- Serve cold: Straight from the fridge, they are like a slab of chocolate fudge, which is its own kind of wonderful.
Frequently Asked Questions
Do I need to add eggs or oil to brownie mix when using condensed milk?
No. The condensed milk replaces every wet ingredient the box instructions list. You simply stir it into the dry mix and bake.
Can I use fat-free sweetened condensed milk?
You can, but the brownies will be noticeably less rich and the texture will be a little more cakey than fudgy. Full-fat is worth it here.
Can I freeze these brownies?
Yes. Wrap individual squares tightly in plastic wrap, then place them in a zip-top bag. They freeze well for up to 2 months. Thaw in the fridge overnight.
My batter was so thick I could barely spread it. Is that right?
Definitely. The mixture is closer to a stiff cookie dough than a pourable brownie batter. Pressing it evenly into the pan with the back of a spatula does the job.
