- 1/2 cup peanut butter
- 1/2 cup white baking chocolate chips (I used Ghirardelli)

How to Make OMG Peanut Butter Cup Brownies
Step 1: Preheat the Oven
Preheat your oven to 350 degrees Fahrenheit.
Step 2: Prepare the Baking Pan
Line a 9×13 baking pan with heavy-duty foil and lightly grease it with vegetable shortening. Alternatively, you can line it with parchment paper.
Step 3: Melt the Chocolate Mixture
In a small saucepan over low heat, melt the unsalted butter. Add the unsweetened chocolate and bittersweet chocolate chips while stirring constantly with a small whisk until everything is melted and smooth. Once done, turn off the heat and let it sit on the burner.
Step 4: Whisk Eggs
In a large mixing bowl, crack in the eggs and lightly whisk them until blended together.
Step 5: Combine Sugars
In another bowl, whisk together granulated sugar, brown sugar, and salt. Then add this mixture to the eggs and mix until just incorporated.
Step 6: Mix in Chocolate
Add the melted chocolate mixture into the egg-sugar mixture. Stir until just combined.
Step 7: Add Vanilla
Briefly whisk in the vanilla extract until evenly distributed.
Step 8: Incorporate Dry Ingredients
In another bowl, sift together flour and baking powder. Gradually add this mixture into the wet ingredients using a silicone spatula until fully mixed.
Step 9: Layer Batter with Peanut Butter Cups
Pour about two-thirds of the brownie batter into your prepared pan, spreading it evenly. Push down one bag of peanut butter cups throughout the brownie batter before layering on the remaining batter on top.
Step 10: Sprinkle Chocolate Chips
Sprinkle milk chocolate chips over the top layer of brownie batter.
Step 11: Bake Brownies
Bake in preheated oven for about 35 minutes or until a toothpick inserted comes out clean. Transfer to a cooling rack and let cool for about 15 minutes.
Step 12: Add Toppings
Scatter roughly chopped peanut butter cups on top of warm brownies. Refrigerate them briefly so they can set.
Step 13: Prepare Drizzle
While brownies cool, melt together peanut butter and white chocolate in the microwave for one minute. Stir briskly; if needed, return to microwave in increments of fifteen seconds until fully melted.
Step 14: Drizzle Over Brownies
Transfer melted mixture into a ziplock bag; snip off one corner. Drizzle back and forth across cooled brownies.
Step 15: Serve
Once set, cut into squares and enjoy! These brownies are best served at room temperature.

Perfecting your OMG Peanut Butter Cup Brownies takes practice and attention to detail. Follow these tips for the best results.
- Use Room Temperature Eggs – This ensures they mix well into the batter, creating a smoother texture in your brownies.
- Melt Chocolate Slowly – Melting chocolate over low heat prevents it from burning, ensuring a smooth blend with butter.
- Don’t Overmix – Mix only until combined to avoid tough brownies; this keeps them fudgy and soft.
- Check for Doneness – Insert a toothpick into the center; it should come out clean or with just a few moist crumbs for perfect fudgy brownies.
- Cool Before Cutting – Allowing brownies to cool completely helps them set properly, making cutting easier and cleaner.

Common Mistakes to Avoid
Making OMG Peanut Butter Cup Brownies can be a delight, but there are common pitfalls to watch for. Here are mistakes to avoid:
Not using room temperature eggs: Cold eggs can affect the texture of your brownies. Always use eggs at room temperature for better mixing and a fudgier result.
Overmixing the batter: Stirring too much can make your brownies tough. Mix just until combined to keep them soft and chewy.
Ignoring baking times: Every oven is different, so don’t rely solely on the timer. Check your brownies a few minutes before the suggested time to avoid overbaking.
Using incorrect pan size: The recipe is for a 9×13 pan. Using a smaller pan will lead to thicker brownies that may not bake evenly.
Skipping the cooling time: Cutting into warm brownies can result in a messy texture. Let them cool for at least 15 minutes before slicing.
