How to Make Peanut Butter Brownies

Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking pan to ensure your brownies slide out smoothly once baked.
Mix Wet Ingredients: In a large mixing bowl, cream together the butter, granulated sugar, and brown sugar until the mixture is smooth and fluffy. Add in the eggs one at a time, mixing well after each addition, followed by the vanilla extract.
Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, cocoa powder, and a pinch of salt. This dry mix will bring structure to your brownies.
Combine Mixtures: Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Be careful not to over-mix—the batter should remain thick but well-blended.
Add Peanut Butter: Now for the fun part! Swirl in the peanut butter using a spatula or a knife for a marbled effect. This will give your brownies that luscious peanut butter taste throughout.
Bake: Pour the brownie batter into your prepared pan, spreading it evenly. Place in the preheated oven and bake for 40-45 minutes. They’re ready when a toothpick inserted into the center comes out with a few moist crumbs attached.
Cool: Once baked, allow the brownies to cool in the pan for at least 10 minutes. This will help them set better and make slicing easier.

Optional: Top with a sprinkle of sea salt for an extra flavor boost!

Storage Tips for Peanut Butter Brownies

Room Temperature: Store your peanut butter brownies in an airtight container at room temperature for up to 3-4 days to keep them soft and fudgy.

Fridge: For extended freshness, you can refrigerate the brownies, which will keep them good for up to one week. Allow them to come to room temperature before serving for the best experience.

Freezer: To enjoy these delectable brownies later, freeze them wrapped individually in plastic wrap and then placed in a zip-top bag for up to three months. Thaw them overnight in the fridge before indulging.

Reheating: If you prefer warm brownies, pop them in the microwave for about 10-15 seconds. This will revive their fudginess without drying them out!

Make Ahead Options

These delicious Peanut Butter Brownies are perfect for meal prep enthusiasts looking to save time in the kitchen! You can prepare the batter up to 24 hours in advance; simply mix all the ingredients (except the peanut butter) and store it in an airtight container in the refrigerator. When you’re ready to bake, just swirl in the peanut butter and pour it into your greased pan. Alternatively, you can bake the brownies and store them in an airtight container at room temperature for up to 3 days. To keep them fresh, place a piece of wax paper between layers and always allow them to cool completely before storing. When it’s time to indulge, just slice and serve for a delectable treat that will taste just as delicious as fresh-baked!

Expert Tips for Peanut Butter Brownies

Use Room Temperature Ingredients: Ensure your butter and eggs are at room temperature for better mixing and a smoother brownie batter.

Cool Completely: Allow your brownies to cool fully in the pan for cleaner cuts when slicing, and use a sharp knife for the best results.
Experiment with Swirls: For a gourmet touch, try varying the swirling technique of the peanut butter—make it grand or subtle according to your preference!
Storage Secrets: Keep your peanut butter brownies in an airtight container at room temperature for up to 3-4 days to maintain moisture and flavor.

Peanut Butter Brownies Recipe FAQs

How do I select the right peanut butter for my brownies?
Choosing the right peanut butter can influence the texture and taste of your brownies. For a smooth and creamy consistency that’s perfect for marbling, I recommend using smooth peanut butter. If you love crunch, feel free to substitute it with crunchy peanut butter, which adds delightful texture. Just make sure it’s well-stirred, especially if you’re using natural peanut butter, as the oils can separate.

How should I store my peanut butter brownies?
Store your peanut butter brownies in an airtight container at room temperature for up to 3-4 days. This will help maintain their softness and fudginess. If they last longer than that (which is unlikely!), refrigerating them can extend their freshness to about one week. Just remember to allow them to come back to room temperature for the best flavor experience!

Can I freeze peanut butter brownies, and how do I do it?
Absolutely! To freeze your peanut butter brownies, let them cool completely after baking, then wrap each brownie individually in plastic wrap. Place them in a zip-top bag or airtight container, and they can be stored in the freezer for up to three months. When you’re ready to enjoy them, simply thaw them in the fridge overnight—this keeps them moist and delicious!

What should I do if my brownies turn out dry?
If your brownies are dry, there are a couple of possibilities to troubleshoot. First, be sure to check your oven temperature with an oven thermometer. If it runs hot, your brownies might bake too fast. Second, make sure to do the toothpick test correctly; remove them from the oven as soon as the toothpick comes out with a few moist crumbs, not clean. Lastly, if you overmixed the batter, it could affect the fudginess. Remember, a touch of care ensures a perfect batch of peanut butter brownies!

Are there any dietary considerations for these brownies?
This peanut butter brownies recipe is vegetarian-friendly, but if you have dietary restrictions, there are simple adjustments you can make! For a dairy-free option, swap out butter for margarine or coconut oil. If you need an egg-free version, a flax egg made from 1 tablespoon of flaxseed meal and 3 tablespoons of water works wonderfully. Just allow it to sit for a few minutes to thicken before mixing it in!

Can I use alternative sweeteners in this recipe?
Yes, you can! If you’re looking for a healthier option, try using coconut sugar as a substitute for granulated or brown sugar. Coconut sugar has a lower glycemic index and delivers a nice caramel flavor. You may also consider using a sugar alternative like Stevia or erythritol, but make sure to check the conversion ratios as these usually require less quantity than regular sugar.
