Imagine biting into a warm, gooey chocolate brownie infused with the irresistible flavors of creamy peanut butter and smooth butterscotch. The peanut butter adds a decadent creaminess that complements the rich chocolate base.

How To Enjoy Chocolate Fudge Peanut Butter Brownies w/ Butterscotch

Brownies are the perfect dessert to enjoy with a cold glass of milk or hot coffee. They’re perfect for any occasion, whether a special event or a casual dessert. Regardless, it is a sweet and salty treat that will leave you wanting more, so be prepared to stash a few away from others. There’s no wonder why these treats have been around since the late 19th century.

Ingredient Notes:

  • All-purpose flour:Β This is the base for the brownie batter. It gives structure and stability to the brownies.
  • Semi-Sweet Chocolate Chips:Β This ingredient gives a rich chocolate flavor, which is more robust than unsweetened cocoa powder.
  • Instant Coffee:Β This addition brings out the flavor of the chocolate without making the brownies bitter. Just a smidge will do with only a teaspoon included.Β 
  • Unsalted Butter:Β This ingredient provides a rich buttery flavor to the brownies and is melted alongside the semi-sweet chocolate chips. Salted butter has a higher water content, and each brand differs in sodium content. Stick with unsalted for better brownie structure and the ability to control the amount of salt.Β 
  • Sea Salt:Β A small amount of salt helps to balance the sweetness and bring out the flavors of the other ingredients. Table salt can also be used.
  • Granulated Sugar:Β This sweetens the brownies and helps them to become moist.
  • Dark Brown Sugar:Β This ingredient also sweetens the brownies and adds moisture due to the higher water content. It also adds a complex flavor to the brownies by imparting notes of molasses.
  • Eggs:Β This ingredient acts as a binder in the recipe, helping to hold everything together. The yolks contribute to the overall fudgy texture and rich flavor.Β 
  • Vanilla Extract:Β This adds a subtle sweetness and enhances the other flavors in the recipe.
  • Creamy Peanut Butter:Β This ingredient gives the brownies a creamy and nutty flavor and texture. There are a lot of varieties out there. My favorites are the natural varieties that do not need to be stirred (like Skippy Natural Creamy PB or Jif Natural Creamy PB, to name a couple).Β 
  • Butterscotch chips:Β This adds a buttery, caramel-sweet flavor and a nice texture to the brownies. They compliment the peanut butter and chocolate flavors without overpowering them, either.Β

Here are some recipe notes for Butterscotch Peanut Butter Brownies:

  • Overmixing the batter can cause the gluten in the flour to develop, resulting in a more rigid texture. Mix the batter just until the ingredients are combined.
  • Use room-temperature eggs.Β Doing so will help the mixture blend together. Also, when pouring the chocolate/butter mixture, be sure to continuously whisk the mix at the same time IF it is hot to the touch. Otherwise, the eggs may cook from heat shock.
  • The baking time can vary depending on your oven. Overbaking the brownies can cause them to dry out and lose their fudgy texture. To test for doneness, insert a toothpick or cake tester into the center of the brownies. The brownies are done if it comes out clean or with just a few crumbs.
  • It’s essential to let the brownies adequately cool before slicing and serving. This will make it easier to cut the brownies, and doing so too early can negatively impact their texture.
  • If you’re using a different-sized pan, adjust the baking time accordingly. A 9″x9″ pan of brownies will cook faster than a 13″x9″ pan, though the latter is recommended for this recipe.
  • If you’re looking for a nuttier flavor and crunchy texture, add some chopped peanuts to the batter or on top before baking.
  • For additional troubleshooting or tips, refer to my FAQ page. Some topics include tips on measuring ingredients, calibrating your oven, and more!

Storage:

Store leftovers in an airtight container for up to 3 days at room temperature. They can also be frozen for up to a month, double-wrapped in the pan, or wrapped and placed in resealable plastic freezer bags.Β

Ingredients
 
 

Brownies

  • 1 ΒΌ Cups Unsalted Butter refrigerated or room temperature, cut into tablespoons - 283g
  • 10 Ounces Semi-sweet Chocolate Chips 283g
  • 1 Tsp Instant Coffee 1g
  • 4 Large Eggs room temperature

  • 1 Tsp Corn Starch 2g
  • Β½ Cup Creamy Peanut Butter 129g
  • Β½ Cup Butterscotch Chips 85g
  • Β½ Cup Chocolate Chips optional - 90g

Instructions
 

Brownies

  • Preheat the oven to 350Β°F / 177Β°C. Measure out all ingredients.
  • Butter (or spray with nonstick spray) a 13"x9" baking pan and line with parchment paper. Butter the parchment paper.
  • Place the semisweet chocolate chips and sliced butter inside a medium microwave-safe mixing bowl. Cover with a paper towel, and heat in 30-second increments on 50% power, stirring after each interval until the mixture is just fully melted. Stir in the instant coffee.
    For example, it took 7 30-second intervals in a 1000-watt microwave oven before the mixture was entirely melted. This will vary based on your appliance.
  • While the chocolate mixture is melting, whisk the eggs and vanilla together in a large mixing bowl. Add granulated sugar, dark brown sugar, and salt. Whisk until no lumps remain.
  • Once the chocolate butter mixture is fully melted, slowly pour it into the large bowl with the egg mix while continuously whisking until combined.
  • Add the all-purpose flour and cornstarch to the large bowl. Whisk until combined and stop as soon as no streaks of flour remain. Pour the batter into the prepared pan and evenly spread it out.
  • Dot the top of the batter with teaspoon amounts of peanut butter. Using a butterknife or toothpick, gently swirl through each peanut butter mound and drag streaks of it around the batter surface.
  • Add butterscotch chips, and chocolate chips if using, to the top of the batter, scattering them evenly across--no need to press them into the batter.
  • Bake the brownies on the center rack of the oven for 20 minutes. Remove the pan and gently tap it a few times against a hard surface. Place the pan back in the oven and continue cooking until the mixture is just set in the middle and the top of the brownies are shiny and cracked, about 20 minutes longer (oven times vary, so check them around the 30 minute mark and go from there).
    Let cool for 15 minutes or longer before serving. Cut 3 rows x 6 columns for 18 bars.
