Easy 5-Ingredient Flourless Brownies with Chocolate

These flourless brownies get their rich chocolate flavor from both melted chocolate chips and unsweetened cocoa powder. Butter adds richness, while eggs give the batter structure without any flour. The result is a dense, chocolatey brownie that’s especially satisfying once it has cooled and settled into a sliceable square.

With five main ingredients and five minutes of prep, this recipe keeps the mixing simple. You’ll melt the butter and chocolate together, whisk in the remaining ingredients, and bake everything in an 8×8-inch pan. Make a batch for an after-dinner dessert, a weekend gathering, or an afternoon chocolate craving—just leave time for the brownies to cool before cutting.

Equipment

• 8×8-inch baking pan
• Large microwave-safe mixing bowl
• Measuring cups
• Whisk
• Rubber spatula
• Toothpick
• Knife

Ingredients

The batter uses these five ingredients. You’ll also need nonstick cooking spray to prepare the pan, as directed in the original method.

• ½ cup (1 stick) unsalted butter
• 1 cup semisweet or dark chocolate chips
• ½ cup granulated sugar
• 3 large eggs
• ¼ cup unsweetened cocoa powder

For the pan: Nonstick cooking spray.

Ingredient Notes & Substitutions

Unsalted butter: Butter melts with the chocolate to form the base of the batter. Use the full ½ cup called for in the recipe.

Chocolate chips: Both semisweet and dark chocolate chips work as specified. Semisweet gives a sweeter chocolate flavor, while dark chocolate produces a more intense result.

Granulated sugar: Whisk the sugar into the melted butter and chocolate before adding the eggs. Keep the quantity unchanged, even when choosing dark chocolate.

Eggs: Use three large eggs. They are important to the structure of these flourless brownies, so an egg replacement should not be assumed to work without testing.

Unsweetened cocoa powder: Cocoa adds chocolate flavor without extra sweetness. Sweetened hot cocoa mix is not a direct substitute.

How to Make Flourless Brownies

1. Prepare the oven and pan. Preheat the oven to 350°F (175°C). Lightly grease an 8×8-inch baking pan with nonstick cooking spray and set aside.
2. Melt the butter and chocolate. Place the butter and chocolate chips in a large microwave-safe bowl. Microwave for about 2 minutes, stirring every 30 seconds, until completely melted and smooth. Stop once the mixture is smooth rather than continuing to heat unnecessarily.
3. Whisk in the sugar. Remove the bowl from the microwave and whisk in the granulated sugar until evenly mixed.
4. Add the eggs. Add the eggs one at a time, whisking well after each addition until the batter is smooth.
5. Mix in the cocoa. Add the unsweetened cocoa powder and stir until fully incorporated, scraping the bottom and sides of the bowl to catch any dry pockets.
6. Fill the pan. Pour the batter into the prepared baking pan and spread it evenly into the corners.
7. Bake. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
8. Cool and slice. Let the flourless brownies cool completely in the pan before cutting into 9 squares.

Tips for Success

• Use the specified pan size. A different pan changes the batter’s depth and may require a different baking time.
• Stir during melting. The 30-second intervals help the chocolate melt evenly and reduce the chance of scorching.
• Avoid adding eggs to a very hot mixture. If the bowl’s contents are still hot after stirring in the sugar, let them cool slightly before whisking in the eggs.
• Add each egg separately. Whisking between additions helps create an evenly blended batter.
• Break up cocoa lumps. If your cocoa is clumpy, sift it before adding so it blends more easily.
• Check at 25 minutes. Follow the recipe’s clean-toothpick cue and avoid baking longer than needed.
• Cool completely before cutting. Warm flourless brownies are delicate; cooling helps them hold together.

Variations

These optional ideas are separate from the original five-ingredient recipe.

• Dark chocolate brownies: Choose dark chocolate chips for a more intense chocolate flavor.
• Cocoa-dusted brownies: Lightly dust the cooled brownies with additional unsweetened cocoa powder before serving.
• Chocolate-drizzled brownies: Drizzle melted chocolate over the cooled squares for an extra chocolate finish.
• Berry-topped brownies: Serve each square with fresh raspberries or sliced strawberries.

How to Store

At Room Temperature

Once completely cool, place the brownies in an airtight container. Store at room temperature for up to 4 days, as specified in the recipe.

In the Refrigerator

For longer storage, refrigerate in an airtight container for up to 1 week. Refrigeration is optional within the shorter room-temperature storage window.

Freezing

A tested freezing duration and thawing method were [Not provided] for this recipe.

These storage directions apply to the plain brownies. Add fresh fruit or other perishable toppings when serving.

Serving Suggestions

• Serve plain with coffee, tea, or a glass of milk.
• Pair a square with vanilla ice cream for an after-dinner dessert.
• Add fresh berries for a fruity contrast to the rich chocolate.
• Arrange the squares on a dessert platter for a casual gathering or potluck.

For neat presentation, wipe the knife between cuts.

Frequently Asked Questions

Are flourless brownies gluten-free?

The listed batter ingredients do not include flour, but check the labels on the chocolate chips, cocoa powder, and cooking spray if you need to avoid gluten. Also consider cross-contact during preparation.

Can I use dark chocolate instead of semisweet?

Yes. The recipe allows either semisweet or dark chocolate chips in the same 1-cup quantity. Dark chocolate will make the flavor less sweet and more intense.

Can make these without an electric mixer?

Yes. Use a whisk to combine the sugar and eggs with the melted chocolate mixture, then stir in the cocoa with a spatula or spoon.

How do I know when the brownies are done?

Begin checking at 25 minutes. Following this recipe, a toothpick inserted into the center should come out clean. The stated baking range is 25–30 minutes.

Why should I let them cool completely?

Cooling helps the brownies firm up so they hold their shape when sliced. Cutting them while warm can cause them to break apart.

Does the 35-minute total include cooling?

No. The listed total is approximately 35 minutes for preparation and baking. Complete cooling takes additional time, which was not specified.
