Imagine biting into a rich, fudgy square of chocolatey goodness that came together in less time than it takes for your oven to preheat—welcome to the beautiful simplicity of One Bowl Brownies. This recipe is as fuss-free as it gets, promising classic brownie flavor with an indulgent, melt-in-your-mouth center and crackly top, all without piling up a mountain of dirty dishes. Whether you’re baking for a crowd or just need a quick dessert fix, these brownies deliver satisfaction in every bite.

Ingredients You’ll Need

The beauty of One Bowl Brownies lies in their simplicity—every ingredient is carefully chosen to create deep flavor, perfect texture, and irresistible aroma. Let’s take a quick look at what each brings to this classic treat:

Unsalted Butter (1/2 cup, melted): Butter forms the rich, flavorful base and keeps the brownies moist and soft.
Granulated Sugar (1 cup): Sweetens the batter and helps create that signature crackly brownie top.
Large Eggs (2): Eggs bind the mixture and add a lovely, tender structure to each square.
Vanilla Extract (1 tsp): Gives an undertone of warmth and rounds out the chocolate flavor.
Unsweetened Cocoa Powder (1/3 cup): The star ingredient for deep, true chocolate flavor—use a good quality brand if you can.
All-Purpose Flour (1/2 cup): Just enough flour keeps the brownies dense and fudgy, not cakey.
Salt (1/4 tsp): Enhances the chocolate and balances the sweetness.
Baking Powder (1/4 tsp): Lifts the batter slightly for a tender, balanced crumb without making it airy.
Chocolate Chips or Chunks (1/2 cup, optional): For pockets of gooey, melty chocolate throughout—totally worth including!

How to Make One Bowl Brownies

Step 1: Prep Your Pan and Oven

Begin by preheating your oven to 350°F (175°C). Take an 8×8-inch baking pan and either grease it lightly or line it with parchment paper, making sure there’s a bit of overhang for easy brownie removal later. This tiny bit of work at the start is your insurance for perfect, mess-free slicing.

Step 2: Whisk Together Butter and Sugar

In your largest mixing bowl—after all, this is a true One Bowl Brownies recipe—whisk the melted butter and sugar together. Mixing them well at this stage creates that irresistible shiny, crackly top everyone craves in a good brownie.

Step 3: Add Eggs and Vanilla for Richness

Crack in the eggs and pour in your vanilla extract. Whisk thoroughly until the mixture looks smooth, glossy, and slightly thickened. Don’t rush this bit; it’s what gives your brownies their dense, fudgy character.

Step 4: Incorporate Dry Ingredients Gently

Sift in the cocoa powder, flour, salt, and baking powder directly into the bowl. Stir gently with a spoon or spatula just until you don’t see any more dry streaks—overmixing can turn your perfect fudgy brownies into chewy, tough ones.

Step 5: Fold in Chocolate Chips and Bake

If you’re adding chocolate chips or chunks, now’s the time to fold them into the batter. Pour the batter into your prepared pan and smooth out the top. Slide the pan into your preheated oven and bake for 20–25 minutes—closer to 20 for ultimate fudginess, 25 for something a little cakier. Let them cool completely in the pan for the cleanest slices.

How to Serve One Bowl Brownies

Garnishes

Sometimes a light dusting of powdered sugar or a quick sprinkle of flaky sea salt is all you need to dress up your One Bowl Brownies. For a fancier touch, add a swirl of caramel, a drizzle of melted chocolate, or a handful of fresh raspberries on top just before serving.

Side Dishes

If you want to really wow your family or guests, try serving your brownies alongside a scoop of vanilla or coffee ice cream. Whipped cream, fresh berries, or a small glass of ice-cold milk also pair beautifully with their rich, chocolatey flavor.

Creative Ways to Present

Transform your One Bowl Brownies into a plated dessert by cutting them into bite-sized cubes and threading them onto skewers with marshmallows and strawberries. You can also stack brownie squares to create an eye-catching, rustic brownie “cake” layered with whipped cream, or tuck them into lunchboxes for the ultimate midday treat.

Make Ahead and Storage

Storing Leftovers

One Bowl Brownies keep wonderfully at room temperature for up to 3 days. Simply place the cooled, sliced brownies in an airtight container—I recommend separating layers with parchment paper to prevent sticking.

Freezing

If you’re planning to store them longer, brownies freeze beautifully. Wrap individual brownies tightly in plastic wrap and store them in a freezer-safe bag or container; they’ll keep for up to 3 months. Thaw them on the counter for an ideal no-fuss treat any time you need one.

Reheating

To recapture that fresh-from-the-oven magic, pop a brownie into the microwave for 10 to 15 seconds. The chocolate chips will become melty again, and the brownie’s center stays delightfully soft—pure comfort in seconds.

FAQs

Can I double the recipe for a larger crowd?

Absolutely! Double all ingredients and bake in a 9×13-inch pan. You might need to add a few minutes to the baking time; just keep an eye on the center with a toothpick test.

What can I use instead of butter?

If you’re out of butter, melted coconut oil or a neutral oil like canola will work. However, butter gives the brownies their signature rich flavor, so substitutions will slightly alter the taste and texture.

How do I know when my One Bowl Brownies are done?

Start checking at the 20-minute mark by poking the center with a toothpick. If it comes out with a few moist crumbs (not wet batter), they’re perfect! Resist the urge to overbake for ultimate fudginess.

Can I add nuts or other mix-ins?

Definitely! Stir in chopped walnuts, pecans, or even a swirl of peanut butter or caramel for a fun twist. Just keep total mix-ins to about 3/4 cup so you don’t overwhelm the batter.

How do I get clean brownie slices?

Let your brownies cool fully in the pan, then lift them out using the parchment. Use a sharp knife, wiping it clean between cuts; this ensures beautiful, bakery-style squares every time.

Final Thoughts

These One Bowl Brownies genuinely deliver everything you crave in a homemade dessert: easy preparation, rich chocolate flavor, and minimal cleanup.
