Step-by-Step: Milk Chocolate & Peanut Butter Ganache Brownies

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, allowing some overhang for easy removal later.
Step 2: Melt the Chocolate and Butter
In a double boiler or microwave, combine the chopped dark chocolate, milk chocolate, and 6 tablespoons of unsalted butter. Melt until smooth, stirring frequently to avoid burning.
Step 3: Combine Sugars and Eggs
In a large mixing bowl, whisk together the brown sugar, granulated sugar, and eggs until the mixture is smooth. Add in the vanilla extract and stir until well combined.
Step 4: Mix in the Chocolate
Once the chocolate and butter mixture has cooled slightly, pour it into the sugar and egg mixture, stirring to combine.
Step 5: Add Dry Ingredients
Sift together the all-purpose flour, cocoa powder, and fine sea salt. Gradually fold the dry ingredients into the wet mixture until just combined. Be careful not to overmix!
Step 6: Bake the Brownies
Pour the brownie batter into the prepared pan, smoothing the top with a spatula. Bake for about 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Step 7: Prepare the Peanut Butter Filling
While the brownies are baking, make the peanut butter filling. In a mixing bowl, beat together 6 tablespoons of softened butter, creamy peanut butter, powdered sugar, and a pinch of sea salt until smooth and creamy.
Step 8: Assemble the Brownies
Once the brownies have cooled for about 10 minutes, spread the peanut butter filling evenly over the top. Allow the brownies to cool completely.
Step 9: Make the Ganache
In a small saucepan, heat the heavy cream until just simmering. Remove from heat and stir in the finely chopped dark and milk chocolates and corn syrup until smooth and glossy.
Step 10: Top with Ganache
Pour the ganache over the cooled brownies and spread evenly. Refrigerate for at least 30 minutes to set the ganache before slicing.
Seasonal Serving Ideas
- Top with crushed candy canes for a festive holiday treat.
- Serve warm with a scoop of vanilla ice cream during summer gatherings.
- Drizzle with caramel sauce for a decadent fall dessert.
- Pair with fresh berries in the spring for a refreshing contrast.
Problems & Prevention
- Brownies are too dry: Ensure you don’t overbake. A toothpick should have moist crumbs, not clean.
- Ganache is too thick: If it sets too firmly, warm it slightly and stir to loosen it up.
- Peanut butter filling is too runny: Make sure the butter and peanut butter are at room temperature and not melted.
- Brownies stick to the pan: Always line your baking pan with parchment paper for easy removal.
Make Ahead Like a Pro
You can prepare the brownie batter and peanut butter filling a day in advance. Store the brownie batter in the refrigerator, and when you’re ready, bake it fresh. The ganache can also be made ahead of time; just reheat it gently before pouring over the brownies.
Your Questions, Answered
Can I use dark chocolate instead of milk chocolate in the ganache?
Absolutely! Using all dark chocolate will give you a richer, more intense flavor, which pairs wonderfully with the sweetness of the peanut butter.
Can I substitute natural peanut butter for creamy peanut butter?
Yes, but be aware that natural peanut butter tends to be more oily. You may need to adjust the powdered sugar to achieve the right consistency for the filling.
How do I store leftover brownies?
Store leftover brownies in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. They can also be frozen for longer storage.
Can I add nuts to the brownie batter?
Absolutely! Chopped peanuts or walnuts would add a delightful crunch and complement the peanut butter flavor beautifully.
