Ingredients for Peanut Butter Cup Blondies
List of Ingredients
To make these tasty blondies, gather these ingredients:
- 1 cup creamy peanut butter
- 1/2 cup unsalted butter, melted
- 1 cup brown sugar, packed
- 1/2 cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 1 cup all-purpose flour
- 1/2 teaspoon baking powder
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
- 1 cup mini chocolate chips
- 1 cup mini peanut butter cups, chopped (plus extra for topping)
Measurement Details
When measuring, be precise for the best results. Pack the brown sugar tightly in a cup. This ensures you get the right sweetness. For the peanut butter, use a measuring cup. Spread it evenly to avoid air bubbles. For the flour, scoop it gently into the cup and level it off with a knife. This keeps it light and fluffy.
Ingredient Substitutions
If you need to swap items, here are some good options:
- Use almond butter or sunflower seed butter for a nut-free version.
- Replace unsalted butter with coconut oil for a dairy-free option.
- If you want less sugar, use a sugar substitute that measures like sugar.
- You can skip mini chocolate chips and use dark chocolate chunks instead.
- For a fun twist, add white chocolate chips or chopped nuts to the mix.
These substitutions keep the blondies delicious while catering to different diets. Enjoy experimenting!

Step-by-Step Instructions
Preparation Steps
1. Start by preheating your oven to 350°F (175°C). Line an 8x8 inch pan with parchment paper. Leave some paper hanging over the edges for easy removal.
2. In a medium bowl, mix 1 cup of creamy peanut butter with 1/2 cup of melted butter. Stir until smooth.
3. Add 1 cup of packed brown sugar and 1/2 cup of granulated sugar. Mix until the mixture is creamy.
4. Beat in 2 large eggs one at a time. Add 2 teaspoons of vanilla extract. Mix well until everything is combined.
5. In another bowl, whisk together 1 cup of all-purpose flour, 1/2 teaspoon of baking powder, 1/4 teaspoon of baking soda, and 1/4 teaspoon of salt.
Baking Process
6. Gradually fold the dry ingredients into the wet mixture. Mix until just combined to keep your blondies soft.
7. Gently fold in 1 cup of mini chocolate chips and 1 cup of chopped mini peanut butter cups.
8. Pour the batter into the lined baking pan. Spread it out evenly.
9. Top with extra chopped peanut butter cups, pressing them a bit into the batter.
10. Bake for about 25-30 minutes. The edges should be golden, and a toothpick should come out with a few moist crumbs.
Cooling and Serving Guidelines
11. Let the blondies cool in the pan for about 10 minutes. Use the parchment paper to lift them out.
12. Place them on a wire rack to cool completely. Once cool, cut them into squares and serve. Enjoy each sweet bite!
Tips & Tricks for Perfect Blondies
Avoiding Common Mistakes
To make the best peanut butter cup blondies, pay close attention to your measurements. Use a kitchen scale for accuracy, especially with flour. Too much flour can make them dry. Always mix the wet and dry ingredients separately first. This helps avoid lumps and ensures even blending. Do not overmix your batter once you combine the dry and wet ingredients. Overmixing leads to tough blondies.
Best Practices for Texture
For a chewy texture, use brown sugar, as it adds moisture. Melt the butter, but don’t let it cool completely. Warm butter helps create a soft, fudgy center. Make sure to fold in the chocolate chips and peanut butter cups gently. This keeps their shape and provides bursts of flavor in every bite. The edges should be golden, while the center remains slightly soft for the best result.
Serving Suggestions and Pairings
Serve these blondies warm for a gooey treat. Pair them with a scoop of vanilla ice cream for a delightful dessert. Drizzle some hot fudge or chocolate sauce on top for extra sweetness. You can also enjoy them with a glass of cold milk or a cup of coffee. For a fun twist, add a sprinkle of sea salt on top before serving. This contrast enhances the rich flavors.
Pro Tips
- Use Room Temperature Ingredients: Make sure your eggs and butter are at room temperature for a smoother batter and better incorporation.
- Don't Overmix: When combining the dry and wet ingredients, mix until just combined to keep your blondies chewy and not cakey.
- Customize Your Toppings: Feel free to add more chocolate chips, nuts, or even a drizzle of caramel on top for extra flavor.
- Check for Doneness: Use a toothpick to test doneness; it should come out with a few moist crumbs for the perfect blondie texture.
Variations of Peanut Butter Cup Blondies
Healthier Ingredient Options
You can make your blondies healthier by swapping some ingredients. Use natural peanut butter instead of creamy. This change cuts sugar and adds protein. You can also use coconut oil to replace unsalted butter. For a lower sugar option, try coconut sugar instead of brown sugar. If you want a gluten-free treat, use almond flour or gluten-free flour blends. These swaps keep the blondies tasty while making them a bit better for you.
Flavor Variations
You can mix up the flavors in your blondies easily. Add a pinch of cinnamon or nutmeg for warmth. Want a chocolate twist? Try adding cocoa powder to the batter. You can also use butterscotch chips along with the chocolate chips. If you love banana, mash one into the mix for a fruity flavor. Each change adds a fun new taste to your blondies.
Mixing in Additional Toppings
Toppings can take your blondies to the next level. Try adding chopped nuts like walnuts or pecans for crunch. You can also sprinkle sea salt on top for a sweet and salty combo. Want more chocolate? Add a drizzle of melted chocolate over the cooled blondies. For a fun treat, fold in some marshmallows. These extras make every bite special and yummy.
Storage Information
Best Storage Practices
To keep your peanut butter cup blondies fresh, store them in an airtight container. This will help maintain their soft texture and rich flavor. You can leave them at room temperature for up to three days. If you want them to last longer, consider refrigerating them. Just make sure to wrap them tightly to avoid drying out.
Freezing Options
Freezing blondies is a great option if you want to save some for later. To freeze, cut the blondies into squares first. Wrap each square in plastic wrap, then place them in a freezer-safe bag. They can last in the freezer for up to three months. When you’re ready to enjoy them, simply thaw them in the fridge overnight or at room temperature for a few hours.
Shelf Life Tips
For the best taste, eat the blondies within the first week. After that, they may lose some freshness. If you notice any changes in texture or smell, it’s best to toss them. Always check for mold or any off smells before indulging. Keeping them in a cool, dry place will help them stay tasty longer.
