Ingredients
To make these yummy peanut butter cup blondies, you’ll need simple, easy-to-find ingredients. Here’s what you will gather:
– 1 cup creamy peanut butter
– 1/2 cup unsalted butter, melted
– 1 cup brown sugar, packed down
– 2 large eggs, at room temperature
– 1 teaspoon vanilla extract
– 1 cup all-purpose flour
– 1/2 teaspoon baking powder
– 1/4 teaspoon salt
– 1 cup chocolate peanut butter cups, coarsely chopped
– 1/2 cup chocolate chips (optional)
Each ingredient plays a key role. The creamy peanut butter gives these blondies their rich flavor and chewy texture. The unsalted butter adds moisture and helps create a soft crumb. Brown sugar adds sweetness and a hint of caramel taste. Eggs bind everything together and give the blondies structure.
The vanilla extract adds a warm aroma and flavor. Flour, baking powder, and salt work together to create the right texture and lift. Finally, the chocolate peanut butter cups add bursts of chocolate and peanut flavor. You can also add chocolate chips for extra chocolatey goodness.
Gather these ingredients, and you are ready to start making something special!

Step-by-Step Instructions
Preheat and Prepare Your Pan
First, you need to preheat your oven to 350°F (175°C). Grab a 9×9 inch baking pan. You can either grease it with some butter or line it with parchment paper. This makes it easy to remove the blondies later.
Mix Peanut Butter and Butter
In a large bowl, add 1 cup of creamy peanut butter and 1/2 cup of melted unsalted butter. Use a whisk or spatula to mix them together. Keep mixing until the mixture is smooth and well blended.
Combine Sugars and Eggs
Next, add 1 cup of packed brown sugar into the bowl. Stir it in well. Make sure it mixes nicely with the peanut butter mixture. Then, add 2 large eggs, one at a time. Mix well after each egg. Don’t forget to add 1 teaspoon of vanilla extract for flavor!
Incorporate Dry Ingredients
In a separate bowl, whisk together 1 cup of all-purpose flour, 1/2 teaspoon of baking powder, and 1/4 teaspoon of salt. Once mixed, slowly fold this dry mixture into your wet ingredients. Use a rubber spatula or wooden spoon. Be careful not to overmix; stop as soon as you see no dry flour.
Add Chocolate Peanut Butter Cups
Now, gently fold in 1 cup of coarsely chopped chocolate peanut butter cups. If you want extra chocolate, you can add 1/2 cup of chocolate chips. Make sure they are spread evenly in the batter.
Bake and Cool
Pour the thick batter into your prepared pan. Use a spatula to spread it evenly. Place the pan in the oven and bake for 20-25 minutes. Check if they are done by inserting a toothpick into the center. It should come out clean or with a few moist crumbs. Once baked, let the blondies cool in the pan for about 10 minutes. Then, transfer them to a wire rack to cool completely.
Tips & Tricks
Achieving the Perfect Texture
To get that chewy yet soft texture, mix your batter carefully. Overmixing can make the blondies tough. After adding the flour, only stir until you see no dry flour. The batter should be thick but smooth. If you want extra gooeyness, add more chocolate peanut butter cups.
How to Store for Freshness
Keep your blondies fresh by storing them in an airtight container. They stay great at room temperature for about three days. If you want them to last longer, refrigerate them. Just remember to let them come back to room temperature before serving to enjoy their full flavor.
Presentation Tips for Serving
Cut the blondies into even squares for a nice look. Place them on a colorful platter to catch the eye. For a special touch, drizzle melted chocolate on top. You can also add a scoop of vanilla ice cream next to them for a delightful dessert experience.
Pro Tips
- Use Room Temperature Eggs: This helps the batter to emulsify better, resulting in a smoother texture and more even baking.
- Don’t Overmix the Batter: Once you combine the dry and wet ingredients, mix just until incorporated to avoid tough blondies.
- Cool Completely Before Cutting: Allow the blondies to cool fully to ensure clean cuts and prevent them from crumbling.
- Experiment with Mix-Ins: Feel free to add nuts, dried fruits, or different types of chocolate for a personalized twist on the recipe.
Variations
Vegan Peanut Butter Cup Blondies
You can make these blondies vegan by swapping the eggs. Use 1/4 cup of unsweetened applesauce for each egg. This keeps the blondies moist and tasty. Also, choose a vegan butter and dairy-free chocolate peanut butter cups. The flavor stays rich and creamy, just like the original.
Gluten-Free Option
For a gluten-free treat, swap the all-purpose flour for a gluten-free blend. Many brands work well in baking. Look for blends that include a mix of rice flour and tapioca starch. This change gives you the same great texture without the gluten. Always check labels to ensure your chocolate peanut butter cups are also gluten-free.
Additional Mix-Ins and Toppings
Get creative with your blondies! You can add chopped nuts like walnuts or pecans for crunch. If you want more chocolate, toss in some chocolate chips. Dried fruits, like cranberries or cherries, can add a fun twist. For a fun topping, drizzle melted chocolate over the cooled blondies for a sweet finish. Enjoy mixing and matching to find your perfect flavor!
Storage Info
Room Temperature Storage
You can keep peanut butter cup blondies at room temperature. Place them in an airtight container. They stay fresh for about three days. Make sure to keep them in a cool and dry place. If you add chocolate drizzle, let it set before storing.
Refrigeration Guidelines
If you want to keep the blondies longer, refrigerate them. They last up to a week when stored this way. Use an airtight container to prevent them from drying out. Before serving, let them sit at room temperature for a bit. This makes them soft again.
Freezing Instructions
To freeze blondies, first cut them into squares. Wrap each square in plastic wrap. Then, place the wrapped blondies in a freezer-safe bag or container. They can stay frozen for up to three months. When ready to eat, thaw them in the fridge overnight. You can warm them in the oven or microwave for a gooey treat.
FAQs
Can I use natural peanut butter instead?
Yes, you can use natural peanut butter. It will change the texture slightly. Natural peanut butter is often less sweet and more oily. You may want to add a bit more sugar or adjust the flour to keep the batter thick.
How do I know when the blondies are done?
Check the edges of the blondies. They should look golden brown. Insert a toothpick in the center. If it comes out with a few moist crumbs, they are ready. If it’s wet, bake for a few more minutes.
What can I substitute for eggs in this recipe?
You can use flax eggs as a substitute. Mix one tablespoon of ground flaxseed with three tablespoons of water. Let it sit for five minutes. This will help bind the blondies like eggs do.
Can I add nuts or other candies?
Absolutely! You can add chopped nuts or other candies. Some great choices are walnuts, pecans, or M&M’s. Just be sure to keep the total mix-ins balanced so the batter stays thick.
How do I reheat leftover blondies?
To reheat, place a blondie in the microwave for about 10-15 seconds. This warms it up without drying it out. You can also warm them in the oven at 350°F for about five minutes. Enjoy them warm!

- 1 cup creamy peanut butter
- 1 2 cup unsalted butter, melted
- 1 cup brown sugar, packed down
- 2 large eggs, at room temperature
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1 2 teaspoon baking powder
- 1 4 teaspoon salt
- 1 cup chocolate peanut butter cups, coarsely chopped
- 1 2 cup chocolate chips (optional)
Preheat your oven to 350°F (175°C). Grease a 9x9 inch baking pan or line it with parchment paper for effortless removal of the blondies after baking.
In a large mixing bowl, combine the melted unsalted butter and creamy peanut butter. Use a whisk or spatula to mix until the two ingredients are smooth and well blended.
Add the packed brown sugar into the peanut butter mixture, stirring vigorously until fully incorporated and smooth.
One at a time, beat in the large eggs, mixing well after each addition. Then, add the vanilla extract and ensure the batter is smooth and creamy before moving on.
In a separate bowl, whisk together the all-purpose flour, baking powder, and salt until evenly mixed.
Gradually fold the dry flour mixture into the peanut butter batter using a rubber spatula or wooden spoon. Mix just until combined; be careful not to overmix as this can affect texture.
Gently fold in the coarsely chopped chocolate peanut butter cups and optional chocolate chips, ensuring they are evenly distributed throughout the batter.
Pour the thick batter into the prepared baking pan, using a spatula to spread it evenly across the pan.
Place the pan in the preheated oven and bake for 20-25 minutes. Check for doneness; the edges should be golden brown, and a toothpick inserted into the center should come out with a few moist crumbs (not wet batter).
Once baked, remove from the oven and allow the blondies to cool in the pan for about 10 minutes. After that, carefully transfer them to a wire rack to cool completely.
For an extra touch of indulgence, drizzle with melted chocolate or serve alongside a scoop of creamy vanilla ice cream.
