Brownies are a classic American dessert, like chocolate chip cookies. Making brownies without flour seems a bit strange, but I promise you the result is even BETTER than a classic brownie. You won’t miss the flour.

This flourless brownie recipe is made with semi sweet chocolate and unsweetened cocoa powder to give it a chocolatey taste and fudgy texture. The chocolate gets mixed with eggs, butter, sugar, vanilla, and a not-so-secret ingredient of cornstarch!

Cornstarch is responsible for giving these brownies a dense chocolate fudge texture along with a crackly crunchy top that makes the perfect texture just like regular brownies.

These flourless brownies are also naturally gluten-free since they are made without any flour or nut flour making them nut-free as well. Whether you avoid gluten or not, you must try brownies without the flour to experience the best chocolate flavor and texture that everyone loves.

Prep the batter in less than 10 minutes, bake and enjoy!

These fudgy chocolate brownies come together quickly and easily with a few basic pantry ingredients.

Ingredients You’ll Need

  • Unsalted Butter – Gives the brownies a rich texture and buttery flavor. To make dairy free, substitute the butter with coconut oil.
  • Granulated Sugar – Adds additional sweetness to the brownie batter along with the semisweet chocolate. Do not substitute for brown sugar.
  • Chopped Semisweet Chocolate – Gives the brownies a dense chocolate flavor when mixed with dry ingredients. You can use bittersweet chocolate but the brownies will not be as sweet.
  • Eggs – Room temperature eggs help the brownies bind together and set while baking and cooling. 
  • Vanilla Extract – Adds a light vanilla flavor to the brownie batter that pairs well with the chocolate brownie flavor. 
  • Unsweetened Cocoa Powder – Gives additional chocolate flavor without adding sweetness. 
  • Cornstarch – Helps improve the texture of the brownie and gives it a nice crusty crunch on top. 
  • Salt – Helps to balance the sweet flavor in the sugar and chocolate.

How To Make No Flour Brownies

Flourless brownies come together easily in one pan in 10 minutes. After baking for 30 minutes, you will have a delicious chocolatey treat!

  1. Prepare for baking: Preheat your oven to 350F. Line a square baking pan (8×8 inches) with foil, then lightly spray with non-stick baking spray. Set the pan aside. 
  2. Prepare the wet ingredients: In a small saucepan, melt the butter over low heat. Stir in sugar until dissolved. Then, add the chopped chocolate and stir until melted and fully incorporated. Remove the saucepan from the heat, then beat in the eggs one at a time until incorporated before stirring in the vanilla extract. 
  3. Add the dry ingredients and mix: While slowly mixing the wet ingredients, stir in the sifted cocoa powder, cornstarch, and salt. Use a spatula to vigorously mix the batter until smooth and shiny. This may take a few minutes. If the batter is still thick and not shiny, keep beating.

It is important to make sure the batter is smooth and shiny before pouring into the baking dish. The batter should look like regular brownie batter. If you don’t mix the batter enough to ensure its smooth and shiny, the brownies will not have the crispy shiny texture on the tops after baking.

4. Bake the brownies: Pour the batter into the prepared baking sheet. Bake for 28-30 minutes or until brownies are completely set in the center. Let them cool in the pan for at least one hour before removing and serving.

Expert Tips

  1. Shiny brownie batter is absolutely needed to make these flourless brownies perfect. You want to mix the batter in the pan vigorously until the batter is shiny. It should look like regular brownie batter. If it is still thick or doesn’t look shiny, then you have not mixed it enough. Keep mixing until the batter is shiny. 
  2. Make sure eggs are at room temperature.
  3. For gluten free: Check to make sure your cornstarch is gluten free.
  4. Cool brownies completely before slicing. Flourless brownies take a bit longer to set after baking.
  5. Use dutch processed cocoa powder to give it the best chocolate flavor with minimal acidity. 
  6. Use chopped chocolate as opposed to chocolate chips for the best texture.


  • Dairy-Free flourless chocolate brownies – If you’d like to make these brownies dairy-free, you can substitute the butter for melted coconut oil. This will give it a very slight coconut flavor. 
  • Add-ins – Fold in your favorite sweet chocolate chips or nuts to add texture and flavor to the brownies. 
  • For paleo flourless brownies – Be sure to use paleo chocolate and coconut sugar or palm sugar. You’ll also need to use coconut oil instead of butter. 
  • Add a sprinkle of flaked salt like Malden sea salt flakes to add texture and subtle salty flavor to the brownies.
  • Add a pinch of cinnamon or pumpkin pie spice for a chocolatey fall-flavored brownie. 
  • Drizzle homemade caramel sauce on top of these brownies and serve with a scoop of vanilla ice cream.
  • Add Frosting: These flourless brownies taste great with any type of frosting. Peanut butter frosting and vanilla frosting are great choices. Simply spread the frosting over the top of the brownies in the pan and cut into bars to serve.

Storing: Flourless chocolate brownies will stay fresh outside of the fridge for 3-4 days in an airtight container. Storing them in the fridge will extend the freshness for up to 1 week, but they may be a bit chewier in texture. 
Freezing: To freeze any leftover brownies without flour, place them on a parchment-lined baking sheet after they are completely cooled. Freeze overnight until solid, then transfer them to an airtight container or freezer-safe bag for 3-4 months. Thaw on the countertop before serving.
