Save These bars begin with a fudgy, butter-forward brownie base: whisk melted butter with sugars, fold in eggs, vanilla, sifted cocoa and flour gently to avoid overmixing. Bake until edges are set and the center remains slightly soft, then cool. Pour a glossy ganache of heated cream and chopped chocolate, scatter candy-coated chocolates and chill until set for clean slices.
My kitchen smelled like a elementary school cafeteria the day I decided to recreate Cosmic Brownies from scratch, except this time using real chocolate instead of whatever mysterious substance came in those little foil packets.
I brought a tray of these to a friend's birthday picnic last spring, and three grown adults stopped mid conversation to stare at their plates after the first bite.
Ingredients
- Unsalted butter (170 g, melted): Good butter makes all the difference here, and melting it first creates that dense, fudgy texture without needing a mixer.
- Granulated sugar (200 g) and light brown sugar (100 g, packed): The blend gives you sweetness with a whisper of caramel depth from the brown sugar.
- 2 large eggs: Room temperature eggs incorporate more smoothly into the batter, avoiding any cold streaks.
- Pure vanilla extract (1 tsp): A small amount that quietly rounds out the chocolate without stealing attention.
- Unsweetened cocoa powder (80 g): This is the backbone of your brownie, so use a quality brand you actually enjoy the taste of.
- All-purpose flour (80 g): Measured by spooning into the cup and leveling off, never scooped directly with the measuring cup.
- Fine sea salt (1/2 tsp): Salt in brownies is not optional, it is the thing that makes the chocolate taste like chocolate.
- Semi-sweet chocolate (115 g, chopped): Chop it yourself rather than using chips, because chips contain stabilizers that prevent smooth melting.
- Heavy cream (120 ml): The key to ganache that pours like silk and sets with a professional shine.
- Unsalted butter for ganache (15 g): A small addition that adds elasticity and gloss to the finished topping.
- Rainbow candy coated chocolate chips (50 g): The nostalgic finishing touch, scattered on while the ganache is still wet so they adhere perfectly.
Instructions
- Prep your pan:
- Heat the oven to 175 degrees C (350 degrees F) and line an 8x8 inch square pan with parchment, leaving flaps hanging over two sides like handles you will thank yourself for later.
- Build the sugar butter base:
- Pour the melted butter into a large bowl, add both sugars, and whisk until the mixture looks glossy and the graininess dissolves, about one full minute of enthusiastic stirring.
- Add the eggs and vanilla:
- Crack in the eggs one at a time, whisking after each until the batter lightens slightly in color and looks thick and emulsified.
- Fold in the dry ingredients:
- Sift the cocoa powder, flour, and salt directly over the bowl, then fold gently with a spatula until you see no more dry pockets, resisting the urge to keep stirring.
- Bake with restraint:
- Spread the batter evenly in your prepared pan and bake for 23 to 25 minutes, pulling them out when the edges are firm but the center still jiggles slightly under your fingertip.
- Cool completely:
- Leave the brownies in the pan on a wire rack until they reach room temperature, which takes patience but is nonnegotiable for clean slicing later.
- Make the ganache:
- Pile the chopped chocolate and butter into a heatproof bowl, warm the cream in a small saucepan until it just begins to steam, then pour it over the chocolate and walk away for two full minutes.
- Stir until glossy:
- Starting from the center, stir in small circles with a spatula until the mixture becomes a smooth, dark, glossy sauce that reflects light.
- Top and finish:
- Pour the ganache over the cooled brownie base, spread it evenly, scatter the candy coated chocolates across the surface, then refrigerate for at least 30 minutes until set.
- Slice and serve:
- Grab the parchment handles to lift the whole slab out of the pan, then use a sharp knife to cut 12 bars, wiping the blade between cuts for clean edges.
Save One rainy Saturday I left a plate of these on the counter and came back to find my roommate had eaten four while standing at the sink, which I consider the highest compliment a home baker can receive.
Serving Suggestions
These bars are stunning on their own, but if you want to push them over the top, warm one briefly in the microwave and let a scoop of vanilla ice cream slowly melt over the ganache.
Storing Your Brownies
Keep them in an airtight container in the refrigerator for up to five days, though in my experience they rarely survive past day two.
Variations Worth Trying
The brownie base is incredibly forgiving and welcomes small tweaks once you have made it once or twice.
- A pinch of espresso powder dissolved into the melted butter amplifies the chocolate without adding any coffee taste.
- Swapping in a one to one gluten free flour blend works beautifully for a gluten free version.
- Try serving them chilled for a firmer, candy bar texture or at room temperature for a softer, gooier bite.
Save These brownies are proof that childhood favorites deserve a second act in your adult kitchen, ganache and all.
Recipe FAQs
- → How can I keep the brownies fudgy?
-
Pull the pan from the oven when the edges are set but the center still looks slightly underbaked; cooling in the pan finishes cooking and preserves moisture. Use melted butter and avoid overmixing once flour is added for a dense, fudgy crumb.
- → What’s the best way to make a smooth ganache?
-
Heat the cream until just steaming and pour it over chopped chocolate and butter. Let sit for a minute to melt, then stir slowly from the center outward until glossy. Strain if needed for extra-smooth texture.
- → Can I swap the candy topping for something else?
-
Yes. Try chopped toasted nuts, crushed cookies, or a sprinkle of sea salt for contrast. For a similar colorful look without candy, use mini chocolate chips or small candied fruits.
- → How should I store the bars?
-
Store chilled in an airtight container for up to 4 days to keep the ganache firm. For softer texture, let them sit at room temperature 15–20 minutes before serving.
- → Any tips for enhancing chocolate flavor?
-
Add a pinch of espresso powder or instant coffee to the batter to deepen the chocolate notes without imparting coffee flavor. A touch of fine sea salt also brightens the overall profile.
- → Are there good gluten-free substitutions?
-
Use a trusted 1:1 gluten-free flour blend that contains xanthan gum for structure. Bake times may vary slightly; check for set edges and a slightly soft center.
