Peanut Butter Streusel Brownie Ingredients
• Here’s everything you need to create these delightful brownies!
For the Brownies
- Unsweetened Cocoa Powder – Provides a deep chocolate flavor; you can substitute with Dutch-processed cocoa for a smoother taste.
- Sugar – Sweetens the brownies and ensures a chewy texture; use brown sugar for added moisture and hints of caramel.
- All-Purpose Flour – Gives structure to the brownies; for a gluten-free option, consider using a gluten-free flour blend.
- Eggs – Help bind the ingredients while adding moisture; swap for flax eggs if you need a vegan alternative.

- Peanut Butter – Swirled throughout, it imparts creaminess and nutty goodness; choose creamy or crunchy based on your preference.
For the Streusel
- Brown Sugar – Enhances sweetness and moisture in the streusel; coconut sugar can be a great less-refined alternative.

Step‑by‑Step Instructions for Peanut Butter Streusel Brownies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms, grease a 9-inch square baking pan with butter or non-stick spray to ensure your Peanut Butter Streusel Brownies release easily. Once greased, set the pan aside as you prepare the batter.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine the unsweetened cocoa powder, granulated sugar, and all-purpose flour. Whisk the dry ingredients together until they’re well-blended, creating a uniform mixture. This step is crucial for an even distribution of flavors in your fudgy brownies.
Step 3: Add Eggs and Butter
Melt the butter and let it cool slightly before adding it to the bowl with your dry ingredients. Crack in the eggs and whisk vigorously until the mixture is smooth and thick. This creamy base will be the foundation of your decadent Peanut Butter Streusel Brownies.
Step 4: Swirl in Peanut Butter
Gently warm some creamy peanut butter until it’s pourable. Using a spatula, carefully swirl the melted peanut butter into the brownie batter. The goal is to create lovely ribbons of peanut butter without fully incorporating it, allowing for delightful pockets of flavor in every bite.
Step 5: Prepare the Streusel Topping
In a separate small bowl, combine flour, brown sugar, and melted peanut butter for the streusel. Mix until you achieve a crumbly texture, reminiscent of wet sand. This crumbly topping will complement the soft brownies perfectly, adding that sought-after crunch.
Step 6: Assemble and Bake
Pour the brownie batter into your prepared pan, spreading it evenly. Sprinkle the peanut butter streusel mixture generously over the top. Bake in your preheated oven for 25-30 minutes, or until the edges look firm and a toothpick inserted in the center comes out with a few moist crumbs.
Step 7: Cool and Serve
Once baked, remove your Peanut Butter Streusel Brownies from the oven and let them cool in the pan for about 10-15 minutes. After cooling, transfer them to a wire rack to cool completely before cutting. This ensures clean edges and a fudgier texture, ready for indulgence!

How to Store and Freeze Peanut Butter Streusel Brownies
Room Temperature: Store brownies in an airtight container at room temperature for up to 5 days to keep them fresh and delicious.
Fridge: For extended freshness, refrigerate your Peanut Butter Streusel Brownies in an airtight container for up to a week, ensuring they stay moist and flavorful.
Freezer: Freeze brownies individually wrapped in plastic wrap and stored in a freezer-safe bag for up to 3 months. Thaw at room temperature when ready to enjoy.
Reheating: Reheat brownies in the microwave for about 10-15 seconds, just until warmed through, or enjoy them cold for a fudgy experience!

Make Ahead Options
These Peanut Butter Streusel Brownies are perfect for busy home cooks looking to save time! You can prepare the brownie batter and streusel topping up to 24 hours in advance. Simply mix the dry ingredients and wet ingredients as instructed, but don’t bake them right away. Store the brownie batter in an airtight container in the refrigerator, and the streusel topping in a separate container. Just before you're ready to serve, preheat your oven, pour the batter into the pan, top with the streusel, and bake as directed. This way, you can enjoy fresh, fudgy brownies with minimal effort, just as delicious as if you made them from scratch on the spot!
Tips for the Best Peanut Butter Streusel Brownies
-
Butter Temperature: Ensure your butter is melted and slightly cooled before mixing. This helps achieve the desired fudgy texture and prevents the batter from becoming too greasy.
-
Egg Whisking: Whisk eggs well until they’re frothy before adding to the batter. This adds air, ensuring your brownies have a nice rise and a light texture amidst their richness.
-
Right Baking Time: Keep an eye on your brownies in the oven—baking too long can dry them out. They’re done when a toothpick has moist crumbs, not wet batter.
-
Cutting Technique: For neat slices, allow brownies to cool completely before cutting. A hot knife dipped in water will help create cleaner cuts, enhancing presentation.
-
Customize Flavors: Don’t hesitate to add mini chocolate chips or nuts into the brownie batter for extra indulgence. Just be sure to maintain balance to keep the texture rich and fudgy.
-
Proper Storage: Store your Peanut Butter Streusel Brownies in an airtight container to keep them fresh for up to 5 days—if they last that long!

Peanut Butter Streusel Brownies Recipe FAQs
How do I choose the best peanut butter for my brownies?
Absolutely! You can use creamy or crunchy peanut butter based on your texture preference. Creamy peanut butter creates a smooth integration within the batter, while crunchy adds delightful bites of texture. For a nut-free option, consider sunflower seed butter or tahini to maintain that nutty flavor without allergens.
How should I store my Peanut Butter Streusel Brownies?
You can store your brownies in an airtight container at room temperature for up to 5 days. For improved shelf life, refrigerate them for up to a week. Just make sure they’re in an airtight container to prevent them from drying out.
Can I freeze Peanut Butter Streusel Brownies?
Yes, indeed! To freeze, wrap individual brownies tightly in plastic wrap and place them in a freezer-safe bag. They can be enjoyed within up to 3 months. When you’re ready to indulge, simply thaw them at room temperature or reheat in the microwave for about 10-15 seconds for that freshly-baked experience.
What if my brownies turned out too dry?
If your brownies are dry, it could be due to overbaking. To avoid this, check them at the lower end of the baking time, around 25 minutes. A toothpick inserted should come out with a few moist crumbs. If they come out clean, they may be overdone. Adding a bit more melted butter next time can also help maintain moisture.
Can I make these brownies gluten-free?
Very much so! To make gluten-free Peanut Butter Streusel Brownies, simply substitute all-purpose flour with a gluten-free blend. Remember to adjust any other ingredients that may contain gluten, paying attention to labels. This way, everyone can enjoy these decadent treats!
