Ingredients You’ll Need
The beauty of Nana’s Famous Fudge Brownies Recipe lies in its simplicity. Each ingredient plays a crucial role—from the rich butter that creates moistness, to the unsweetened chocolate that gives the brownies their intense fudgy flavor, and the sugar that balances the bitterness with perfect sweetness. Every component is essential, making this recipe both straightforward and incredibly satisfying.
- 1 cup salted butter (2 sticks): Creates richness and adds moisture that keeps the brownies fudgy.
- 2 ounces unsweetened chocolate (or 3/4 cup cocoa): Provides that deep, chocolatey base for the batter.
- 2 cups granulated sugar: Sweetens the brownies while contributing to their delicate texture.
- 1/4 teaspoon salt: Enhances all the flavors and balances the sweetness.
- 2 teaspoons vanilla: Adds warmth and depth to the chocolate profile.
- 1 1/2 cups flour (spooned and leveled): Gives structure without making the brownies cakey.
- 4 large eggs: Bind everything together and enrich the batter.
- 1 cup chopped walnuts (optional): Adds crunch and a toasty contrast if you want a little texture.
- 1/2 cup salted butter (1 stick) for frosting: Base for the silky, rich fudge topping.
- 2 cups granulated sugar (for frosting): Sweetens the frosting perfectly without overpowering it.
- 1/2 cup milk: Makes the frosting creamy and smooth.
- 1/2 cup cocoa: Brings intense chocolate flavor to the topping.
- 1 teaspoon vanilla (for frosting): Adds a lovely aroma and depth to the fudge.
- Ice water: Used in an ice bath to cool the frosting properly—don’t skip this step!
- 1/2 to 1 cup chopped walnuts (to sprinkle on top): Optional but oh-so-good for added crunch and a beautiful finish.
How to Make Nana’s Famous Fudge Brownies Recipe
Step 1: Prepare Your Pan and Oven
The first thing you want to do is grease a 9×13 inch baking pan so your brownies won’t stick. Preheat your oven to 350 degrees Fahrenheit. Getting these basics right sets the stage for perfect baking.
Step 2: Melt Butter and Chocolate
In a sturdy pot, melt 1 cup of salted butter with 2 ounces of unsweetened chocolate over medium heat. If you prefer, you can substitute with 3/4 cup cocoa powder. Stir gently with a wooden spoon until smooth, then remove from the heat. This step creates a velvety, rich base full of chocolate goodness.
Step 3: Add Sugar and Salt
Into the warm chocolate mixture, stir in 2 cups of sugar and 1/4 teaspoon of salt. This will begin to sweeten your batter while balancing the chocolate’s intensity just right.
Step 4: Stir in Vanilla Extract
Add 2 teaspoons of vanilla extract to enhance that deep chocolate flavor and give the brownies an inviting aroma that will fill your kitchen.
Step 5: Incorporate Flour
Now, gently fold in 1 1/2 cups of flour until just combined. Be careful not to overmix—this keeps the brownies tender and fudgy rather than cakey.
Step 6: Mix in Eggs
Add 4 large eggs and stir until blended. The eggs enrich the batter and help achieve that classic brownie texture that’s moist but holds together perfectly.
Step 7: Optional Walnuts
If you like a bit of crunch, fold in 1 cup of chopped walnuts. Of course, if you prefer pure chocolate indulgence, skip this step—these brownies will shine either way!
Step 8: Spread Batter and Add Walnuts
Pour the batter into your prepared pan. If you’re feeling creative, press walnuts into just half the batter to give everyone a choice between classic and nutty brownies.
Step 9: Bake
Bake at 350 degrees Fahrenheit for about 20-22 minutes. Start checking early with a toothpick; when it comes out clean of wet batter, the brownies are perfectly baked with a slightly fudgy center.
Step 10: Cool Completely
Allow the brownies to cool entirely in the pan. This is super important because spreading the frosting on warm brownies will make it melt and lose that signature fudge consistency.
Step 11: Make the Fudge Frosting
While the brownies cool, prepare your frosting in a clean pot. Melt 1/2 cup salted butter with 2 cups sugar, 1/2 cup milk, and 1/2 cup cocoa over medium-high heat until it reaches a rolling boil. Then set a timer and boil for exactly 1 minute. This step is key for that rich, glossy fudge texture.
Step 12: Flavor and Chill the Frosting
Remove from heat and stir in 1 teaspoon vanilla. Next, place the pot into an ice bath—ice water in a larger bowl—to cool the frosting down without letting any water mix in. Stir occasionally for about 10 minutes until the frosting thickens slightly but remains pourable.
Step 13: Beat the Frosting
Using an electric mixer, beat the frosting for 3 to 5 minutes. It will go from super glossy to a softer sheen. This gives the frosting a smoother, more spreadable texture that’s just perfect.
Step 14: Frost the Brownies
Pour the frosting right over the cooled brownies and spread evenly. If you like walnuts, sprinkle 1/2 to 1 cup on top immediately—this adds a lovely crunch and contrast.
Step 15: Let Set and Serve
Let the frosting set before slicing into delicious squares. Serve with a cold glass of milk for the ultimate indulgence that will have everyone asking for your secret.
How to Serve Nana’s Famous Fudge Brownies Recipe

Garnishes
To make your brownies even more eye-catching and delicious, add a sprinkle of extra chopped walnuts or a light dusting of powdered sugar. For something fancy, a drizzle of caramel or a few fresh berries can add a beautiful pop of color and flavor that pairs wonderfully with the rich chocolate.
Side Dishes
Serve these brownies alongside a scoop of vanilla ice cream or a dollop of freshly whipped cream to elevate the experience. A hot cup of coffee or a creamy latte also complements the warm chocolate notes perfectly, turning a simple dessert into a cozy treat.
Creative Ways to Present
Feeling adventurous? Layer the brownie squares in a dessert trifle with whipped cream and berries for a stunning effect. You can also cut them into bite-sized pieces and serve as part of a dessert platter. For parties, try skewering brownie cubes with marshmallows and fruit for a fun, shareable snack.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers (which might be hard!), keep them tightly covered at room temperature for up to 3 days. This keeps the brownies moist and preserves the luscious frosting without drying out.
Freezing
You can freeze brownies either whole or cut into portions. Wrap them tightly in plastic wrap and then foil to prevent freezer burn. Frozen brownies keep well for up to 3 months. Thaw at room temperature before serving; the frosting might firm back up beautifully in the process.
Reheating
For that just-baked warmth, microwave a brownie square on a microwave-safe plate for 15 to 20 seconds. The heat will soften the fudge frosting and release those decadent chocolate aromas, tricking everyone into thinking they’re fresh from the oven.
FAQs
Can I use unsalted butter instead of salted butter?
Absolutely! Just be sure to add a pinch extra salt to balance the flavors perfectly, as salted butter helps enhance the chocolate and sweetness.
What if I don’t have unsweetened chocolate, can I only use cocoa powder?
You can substitute 2 ounces of unsweetened chocolate with 3/4 cup of cocoa powder, but note that this might slightly change the texture and intensity—still delicious though!
Are walnuts necessary for this recipe?
Not at all! Walnuts are optional and simply add a lovely crunch and nutty taste, but the brownies are incredible even without them.
How do I know when the brownies are done baking?
Start checking around 20 minutes by inserting a toothpick into the center. When it comes out without wet batter—some moist crumbs are okay—they’re ready to come out.
Can I prepare the frosting in advance?
It’s best to prepare the frosting fresh just before spreading it on the brownies. It loses its ideal texture if made too far ahead.

If you want a brownie recipe that brings a warm, nostalgic smile with every bite, Nana’s Famous Fudge Brownies Recipe is a keeper. It hits all the right notes with its rich chocolate flavor, perfect texture, and that unforgettable homemade fudge frosting.

Ingredients
Brownies
- 1 cup salted butter (2 sticks)
- 2 ounces unsweetened chocolate (or substitute 3/4 cup cocoa powder)
- 2 cups granulated sugar
- 1/4 teaspoon salt
- 2 teaspoons vanilla extract
- 1 1/2 cups all-purpose flour (spooned and leveled)
- 4 large eggs
- 1 cup chopped walnuts (optional)
Frosting
- 1/2 cup salted butter (1 stick)
- 2 cups granulated sugar
- 1/2 cup milk
- 1/2 cup cocoa powder
- 1 teaspoon vanilla extract
- Ice water (for ice bath, not for the recipe)
- 1/2 to 1 cup chopped walnuts (for topping, optional)
Instructions
- Prepare the pan and preheat oven: Grease a 9×13 inch baking pan thoroughly and preheat your oven to 350°F (175°C) to ensure even baking.
- Melt butter and chocolate: In a heavy-bottomed 2 or 3 quart pot over medium heat, melt 1 cup of salted butter with 2 ounces unsweetened chocolate (or substitute 3/4 cup cocoa powder), stirring occasionally with a wooden spoon until smooth. Then remove from heat.
- Add sugar and salt: Stir in 2 cups granulated sugar and 1/4 teaspoon salt into the melted chocolate mixture until well combined.
- Incorporate vanilla extract: Add 2 teaspoons vanilla extract and mix thoroughly.
- Mix in flour: Gently stir 1 1/2 cups of spooned and leveled flour into the mixture until it is barely combined; avoid overmixing to keep the brownies tender.
- Add eggs: Add in 4 large eggs and stir carefully until fully incorporated, taking care not to overdo it for a moist texture.
- Optional walnuts: If desired, fold in 1 cup chopped walnuts for added crunch and flavor (note the playful warning from Nana!).
- Transfer batter to pan: Spread the batter evenly into the prepared baking pan. If dividing with walnuts, press the nuts into half of the batter at this point.
- Bake the brownies: Place the pan in the preheated oven and bake for about 20 to 22 minutes, checking early to prevent overbaking. Use a toothpick inserted into the center; it should come out without wet batter but can have moist crumbs.
- Cool brownies: Remove the brownies from the oven and let them cool completely in the pan to avoid melting the frosting later.
- Prepare frosting pot: While the brownies cool, clean the pot used earlier or use a similar-sized pot for the frosting preparation.
- Melt frosting ingredients: Over medium-high heat, melt 1/2 cup salted butter and add 2 cups granulated sugar, 1/2 cup milk, and 1/2 cup cocoa powder. Bring the mixture to a rolling boil, then continue boiling for exactly 1 minute.
- Add vanilla and remove from heat: Remove the pot from heat and stir in 1 teaspoon vanilla extract.
- Set up ice bath: Prepare a bowl with ice and water to create an ice bath. Place the pot with frosting mixture in the ice bath, ensuring no water gets into the frosting.
- Cool frosting: Let the frosting cool for about 10 minutes, stirring occasionally and scraping the pot edges to prevent crusting. It should thicken slightly but remain pourable.
- Beat the frosting: Using an electric mixer, beat the cooled frosting for 3 to 5 minutes until it loses its initial shine but stays easy to pour and spread.
- Frost the brownies: Immediately pour the frosting over the cooled brownies and spread evenly with a spatula.
- Add walnut topping: If desired, sprinkle 1/2 to 1 cup chopped walnuts over the frosting for extra texture and taste.
- Set and serve: Allow the frosting to set before cutting the brownies into 24 squares. Serve alongside cold milk for the ultimate indulgence.
Notes
- Use a heavy-bottomed pot to evenly melt chocolate and butter without burning.
- Do not overmix the batter once eggs are added; overmixing can make brownies tough.
- Keep a close watch while baking to avoid drying out brownies; moist crumbs on a toothpick indicate doneness.
- The fudge frosting requires cooling in an ice bath to thicken properly before beating.
- Be careful to avoid any water getting into the frosting during the ice bath stage to preserve texture.
- Using an electric mixer to beat the frosting is crucial for the right consistency and shine reduction.
- Walnuts are optional but add great texture and flavor to both the batter and frosting topping.
- Allow brownies to cool completely before frosting to prevent melting or sliding.
- For a richer chocolate flavor in the batter, use unsweetened chocolate instead of cocoa powder.
