Ingredient Substitutions
You can swap some ingredients if needed:

Measuring Tips
Accurate measuring helps create the best brownies:
– Use dry measuring cups for cocoa powder and flour.
– Level off the top with a knife for precision.
– Use a liquid measuring cup for melted butter.
– Weigh ingredients for best accuracy, especially for flour.
– Room temperature eggs mix better, so take them out early.
– For sticky peanut butter, spray your measuring cup with oil first.

Step-by-Step Instructions
Preparation and Preheating
First, I preheat my oven to 350°F (175°C). This is the best temperature for baking brownies. Next, I grab a 9×13 inch baking pan. I lightly grease it or line it with parchment paper. This step helps with easy removal later. It saves time and keeps the brownies intact.
Mixing the Batter
In a large bowl, I add the cocoa powder, granulated sugar, and brown sugar. Then, I pour in the melted butter. I whisk these together until smooth. It’s important to mix well. After that, I add the eggs one by one. I whisk well after each egg. This helps them blend in. Finally, I stir in the vanilla extract for a rich flavor. Next, I gently fold in the all-purpose flour and sea salt. I mix until just combined. It’s okay if the batter has some lumps. This makes the brownies fudgy. Then, I stir in the peanut butter until it’s fully mixed. The batter should be thick now.
Layering with Peanut Butter Cups
Now, I pour half of the brownie batter into the prepared pan. I spread it evenly across the bottom. Next, I evenly distribute the halved mini peanut butter cups over the first layer. For extra richness, I sprinkle some chocolate chips on top too. After that, I carefully dollop the rest of the brownie batter over the peanut butter cups. I smooth it out gently to cover them. This step is key for a nice, gooey center.
Tips & Tricks
Perfecting Fudgy Brownies
To make the best fudgy brownies, you need a few key tips. First, use quality cocoa powder. This adds rich flavor. Second, don’t overmix the batter. Stir it until just combined. This keeps the brownies dense and fudgy. Third, avoid overbaking. Check them at 25 minutes. The toothpick should have some moist crumbs, not clean.
Essential Baking Tools
Having the right tools helps make baking easier. Here are some must-haves:
– Mixing bowls: Use large ones for easy mixing.
– Whisk: A sturdy whisk helps combine ingredients well.
– Spatula: A silicone spatula works best for folding.
– Baking pan: Use a 9×13 inch pan for even baking.
– Parchment paper: It helps with easy removal of brownies.
Common Mistakes to Avoid
Many people make simple mistakes when baking brownies. One common mistake is not measuring ingredients correctly. Use a kitchen scale for accuracy. Another mistake is opening the oven door too soon. This can cause the brownies to sink. Lastly, avoid using cold eggs. Room temperature eggs mix better, helping to create a smooth batter.
Pro Tips
- Use Room Temperature Eggs: Make sure your eggs are at room temperature before adding them to the batter. This helps them incorporate more easily, resulting in a smoother brownie texture.
- Don’t Overmix: When combining the dry ingredients with the wet, mix just until combined. Overmixing can lead to tougher brownies, while a gentle fold will keep them fudgy.
- Test for Doneness: Insert a toothpick into the center of the brownies; it should come out with a few moist crumbs. This ensures your brownies remain rich and fudgy.
- Let Them Cool: Allow the brownies to cool completely before slicing. This will help them set and make it easier to get clean cuts without crumbling.
Variations
Flavor Combinations
You can mix flavors to make these brownies even better. Try adding mint extract for a fresh twist. You could also use hazelnut spread instead of peanut butter. This gives a rich, nutty taste. Another option is to add a swirl of raspberry or cherry jam. The fruity notes balance the chocolate well. For spice lovers, a pinch of cinnamon can add warmth too. Each flavor change creates a new treat to enjoy.
Dietary Adjustments (Gluten-Free, Vegan)
If you need a gluten-free version, swap all-purpose flour for almond or coconut flour. These work well and keep the brownies tasty. To make them vegan, replace eggs with flax eggs. Mix one tablespoon of ground flaxseed with three tablespoons of water for each egg. Use plant-based butter or coconut oil too. This keeps the brownies rich without any dairy. These adjustments help everyone enjoy this dessert.
Additional Toppings and Mix-ins
Toppings can elevate your brownies. Drizzle melted chocolate or caramel on top for added sweetness. Chopped nuts, like walnuts or pecans, add crunch and flavor. You can also fold in mini marshmallows for a fun texture. Try adding crushed pretzels for a salty bite. Each topping can change the whole experience, so feel free to get creative!
Storage Info
Storing Brownies Properly
To keep your peanut butter cup brownies fresh, store them in an airtight container. This keeps moisture in and prevents them from drying out. Place a piece of parchment paper between layers if stacking. Keep them at room temperature for about 3-4 days. If you want them to last longer, consider refrigerating them. This can extend their freshness to about a week.
Freezing Instructions
Freezing brownies is a great way to enjoy them later. First, let the brownies cool completely. Then, cut them into squares. Wrap each square tightly in plastic wrap. Place the wrapped brownies in a freezer-safe bag or container. They can stay in the freezer for up to 3 months. When you are ready to enjoy them, just thaw at room temperature for a few hours.
Reheating Tips
For a warm treat, reheat brownies in the microwave. Place a square on a microwave-safe plate. Heat for about 10-15 seconds. Check to see if it’s warm enough. If not, heat in short bursts of 5 seconds. You can also warm them in the oven. Preheat to 350°F (175°C). Place brownies on a baking sheet for about 5-10 minutes. Enjoy them warm, maybe with a scoop of ice cream!
FAQs
How long do peanut butter cup brownies last?
Peanut butter cup brownies last about 3 to 5 days at room temperature. To keep them fresh, store them in an airtight container. This helps maintain their moist texture and rich taste.

Can I make these brownies ahead of time?
Yes, you can make these brownies ahead of time! They are perfect for prepping. You can bake them a day or two in advance. Just let them cool completely before you store them.

What can I substitute for peanut butter?
