Step‑by‑Step Instructions for Marshmallow Peanut Butter Brownies
Step 1: Prepare Peanut Butter Filling
In a medium bowl, combine creamy peanut butter, powdered sugar, unsalted butter, and a pinch of salt. Use a hand mixer or spatula to mix until smooth and well-blended, creating a rich, creamy filling. This decadent mixture will layer beautifully within your Marshmallow Peanut Butter Brownies. Set it aside while you move on to the next steps.
Step 2: Preheat Oven
Adjust your oven rack to the center position and preheat to 350°F (180°C). While the oven is heating, grease a 9×13 inch baking pan and line it with parchment paper, leaving some overhang. This will make it easier to lift the brownies out after baking. Take a moment to prepare your workspace, as these brownies will come together quickly!
Step 3: Mix Dry Ingredients
In a small bowl, whisk together all-purpose flour, baking powder, and a bit of salt until well combined. This mixture forms the backbone of your brownies, providing structure and lightness. Make sure there are no clumps, as a smooth mixture will yield delicious, evenly baked Marshmallow Peanut Butter Brownies.
Step 4: Mix Wet Ingredients
In another large bowl, whisk together room temperature eggs, granulated sugar, brown sugar, canola oil, and pure vanilla extract until the mixture appears thick and pale. The combination should be smooth, ensuring even sweetening and binding for the brownies. This is where the magic begins, so take your time to create a rich, creamy base.
Step 5: Melt Chocolate and Butter
In a small saucepan over low heat, melt chopped bittersweet chocolate and unsalted butter together. Stir frequently until completely melted and smooth, taking care not to scorch the chocolate. Remove from heat and gently incorporate cocoa powder until fully combined. This indulgent chocolate mixture will give your brownies that rich, fudgy flavor.
Step 6: Combine Mixtures
Add the melted chocolate mixture to the egg mixture and whisk until fully combined and smooth. Carefully fold in the dry ingredients with a spatula, mixing until just combined. Avoid over-mixing to maintain the moist, chewy texture that defines your Marshmallow Peanut Butter Brownies. Gently stir until no dry flour remains.
Step 7: Assemble Brownies
Pour the brownie batter into the lined baking pan and spread it evenly. Dollop the prepared peanut butter filling over the brownie batter, then top with generous spoonfuls of marshmallow fluff. Using a knife, gently swirl the fillings into the batter to create a beautiful marbled effect, ensuring each brownie will have delicious layers of flavor.
Step 8: Bake
Place the assembled brownies in your preheated oven and bake for 26-32 minutes. The brownies are done when the edges are set and the center is still slightly glossy. Insert a toothpick into the center; it should come out with a few moist crumbs. Keep an eye on them to avoid overbaking!
Step 9: Cool and Cut
Once baked, remove the pan from the oven and allow it to cool completely on a wire rack. This may take about an hour. Once cool, use the overhanging parchment paper to lift the brownies out of the pan. Cut into squares to serve these delightful Marshmallow Peanut Butter Brownies to friends and family!
Expert Tips for Marshmallow Peanut Butter Brownies
- Parchment Sling: Lining the baking pan with parchment paper makes it a breeze to lift out the brownies for cutting and serving.
- Warm Your Fluff: Microwave the marshmallow fluff for about 15 seconds to soften it, making it easier to dollop and swirl into the brownie batter.
- Avoid Over-Mixing: Stir the batter until just combined to keep your Marshmallow Peanut Butter Brownies chewy and fudgy, instead of dry and crumbly.
- Check for Doneness: Use a toothpick to check; you want it to come out with a few moist crumbs, rather than completely clean, for the perfect texture.
- Experiment with Toppings: Feel free to dress up your brownies with chocolate chips or a drizzle of melted chocolate for an extra indulgent treat!
Make Ahead Options

Marshmallow Peanut Butter Brownies Recipe FAQs
How can I choose ripe ingredients for my brownies?
Absolutely! When selecting peanut butter, opt for creamy varieties that are smooth and have no added sugars or oils. For the best flavor, use eggs that are at room temperature—this helps them blend more effortlessly into the batter!
What’s the best way to store these brownies?
For optimal freshness, store your Marshmallow Peanut Butter Brownies in an airtight container at room temperature for up to 2 days. If you prefer them colder, they can be refrigerated for another 1-2 days. Just make sure the container is sealed well to prevent them from drying out.
Can I freeze my brownies, and how should I do it?
Very! To freeze your brownies, allow them to cool completely before wrapping them tightly in plastic wrap. Then, wrap them again in aluminum foil or place them in a freezer-safe container. They’ll stay fresh for up to 3 months. When you’re ready to indulge, simply thaw them at room temperature or microwave for a few seconds to regain their moist texture.
What should I do if my brownies turn out too dry?
If your brownies are dry, it could be due to over-mixing or overbaking. To prevent this, mix your batter just until combined and avoid the urge to keep stirring. Also, check them a minute or two before the recommended baking time; they should be glossy with a few crumbs on the toothpick. If you’ve already baked them and they’re dry, consider serving with a scoop of ice cream or drizzling them with a warm chocolate sauce to enhance moisture and flavor.
Are there any dietary considerations I should be aware of?
Definitely! If you’re cooking for someone with allergies, remember that peanut butter contains nuts, which are common allergens. For nut-free options, feel free to substitute with sunflower butter or another certified nut-free spread. If you’re catering to vegan diets, you can utilize flax eggs instead of regular eggs and ensure your chocolate is dairy-free.
