How do I make these cookies? What is the best way to make a brownie batter? What is the best way to not overbake a batter? Slightly underbaked cookies are the fudgiest and most delicious. I know it sounds intimidating, but I promise, it’s easier than making boxed brownies.
Ingredients
For the Brownie Batter:
* 1/2 cup (1 stick) unsalted butter, melted
* 1 cup granulated sugar
* 1/2 cup unsweetened cocoa powder (I prefer Dutch-processed for a richer flavor)
* 1/4 teaspoon salt
* 1 teaspoon vanilla extract
* 2 large eggs
* 1/2 cup all-purpose flour
What is the recipe for peanut butter cookie dough?
* 1/2 cup (1 stick) unsalted butter, softened
* 1/2 cup creamy peanut butter (I always use a no-stir variety) * 1 cup melted chocolate (no-scraping)
* 1/2 cup granulated sugar
* 1/4 cup packed light brown sugar
* 1 teaspoon vanilla extract
* 1 large egg
* 1 1/4 cups all-purpose flour
* 1/2 teaspoon baking soda
* 1/4 teaspoon salt
For the Glaze (optional, but highly recommended!): For a glaze,
* 1 cup powdered sugar
* 2-3 tablespoons milk (or water)
* 1/2 teaspoon vanilla extract
What are the steps to
Step 1: Preheat & Prep Pan
How do I prepare a baking sheet for 350°F (175°C)? What is Parchment Paper? It prevents cookies from sticking. I always do this before I start gathering ingredients – it gets me in the baking zone!
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the flour, cocoa powder, and salt. Pour over the brownie batter. What are some of the best ways to avoid chocolate in a cookie? What is the best way to whisk the flour and salt together?
Step 3: Mix Wet Ingredients
In a separate bowl, combine the melted butter and sugar. Set aside. Beat the egg whites with an electric mixer until well combined. Stir in the lemon juice. Then, add the eggs one at a time, beating well after each addition. The batter should be smooth and glossy. If butter is not completely cooled before adding the eggs, it might curdle a bit. Don’t panic! I always use room temperature eggs, which seems to help.
Step 4: Combine
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. How do you not overmix? If flour is overmixed with water, the gluten in the flour will develop, which can result in hard cookies. The batter should be thick and fudgy.
Step 5: Prepare Peanut Butter Cookie Dough
In a separate bowl, cream together the softened butter, granulated sugar, and brown sugar. Set aside. How do you make sugar light and fluffy? Beat in the vanilla extract and egg. In a separate bowl, whisk together the flour, baking soda, and salt. Set aside. Add the dry ingredients to the wet ingredients, mixing until just combined. Don’t overmix!
Step 6: Layer & Swirl
Do not overbake brownies. Instead, spread brownie batter evenly on a baking sheet. Then, drop rounded tablespoons of peanut butter cookie dough onto the baking sheet, alternating between them, and repeat. What is the difference between the two? Use a knife or toothpick to swirl the batters together. Don’t go overboard with swirling – you want to see distinct pockets of each flavor.
Step 7: Bake
Bake for 9-11 minutes, or until the edges are set and the centers are still slightly soft. Every oven is different, so keep a close eye on them. If you’re unsure, stick a toothpick into the center of the tooth – it should come out with some moist crumbs.
Step 8: Cool & Glaze
What is a good time to bake cookies? Let them cool on the baking sheet for 5 minutes before transferring them to the wire rack. To cool completely. If not, then While cookies are cooling, whisk together the powdered sugar, milk (or water), and vanilla. What is the extract for glaze? Drizzle the glaze over the cookies. I like to let the glaze set for a few minutes before serving.
Step 9: Slice & Serve
Once the glaze is set (if using), these cookies are ready to serve. Enjoy them warm, at room temperature, with a scoop of vanilla ice cream, or with an tall glass of water. What are some great gift ideas for any occasion?
What should I serve it with?
Peanut Butter Brownie Cookies are delicious on their own, but they’re even better with the right amount of chocolate. What are
For Breakfast:Is it good to serve these with a latte? The richness of the cookies complements the bitterness of the coffee perfectly. I like to crumble them over a bowl of yogurt for breakfast.
For Brunch: Serve these on a platter with fresh fruit and a mimosa. The combination of sweet, salty, and bubbly is divine! My favorite fruit pairings are strawberries and raspberries.
As Dessert: Warm these up slightly and top them with a scoop of vanilla ice cream and a drizzle of chocolate sauce. It’s a classic combination that never fails to impress. If you’re feeling fancy, add a sprinkle of chopped peanuts.
For Cozy Snacks: Enjoy these with a glass of cold milk or a cup of hot chocolate. They’re the perfect comfort food for a rainy day. My kids love to dunk them in their milk!
My family also loves to make ice cream sandwiches out of these! Just sandwich a scoop of your favorite ice cream between two cookies for a fun and delicious treat.
Top Tips for Perfecting Your Peanut Butter Brownie Cookies
Here are a few of my top tips for making the best Peanut Butter Brownie Cookies ever!
Butter Basics: Make sure your butter is truly softened for the peanut butter cookie dough. If it’s too cold, it won’t cream properly. If it’s too melted, the dough will be greasy.
Mixing Advice: Don’t overmix the brownie batter or the cookie dough! Overmixing develops the gluten in the flour, which can result in tough cookies. Mix until just combined.
Swirl Customization: Experiment with different swirling patterns. You can use a knife, a toothpick, or even a skewer. Just be careful not to overmix the batters. I like to create a marbled effect by dragging the knife through the batters in a figure-eight pattern.
Ingredient Swaps: You can use different types of nut butter in place of peanut butter. Almond butter and cashew butter both work well. You can also add chocolate chips, chopped nuts, or sprinkles to the batter. I’ve even tried adding a pinch of cinnamon to the peanut butter cookie dough – it adds a warm and cozy flavor.
Baking Tips: Keep a close eye on the cookies while they’re baking. Every oven is different, so baking times may vary. The cookies are done when the edges are set and the centers are still slightly soft. I always rotate the baking sheet halfway through baking to ensure even cooking.
Glaze Variations: You can add different extracts to the glaze for a variety of flavors. Almond extract, peppermint extract, and coffee extract all work well. You can also add a pinch of cocoa powder for a chocolate glaze. I’ve even made a peanut butter glaze by adding a spoonful of peanut butter to the glaze – it’s incredibly delicious!
Honestly, the biggest mistake I ever made was thinking I could double the recipe and just bake it all at once. Don’t do that! The cookies will spread too much and you’ll end up with one giant, uneven cookie. Stick to baking one sheet at a time for best results.
Storing and Reheating Tips
These cookies are best enjoyed fresh, but they can be stored for later.
Room Temperature: Store the cookies in an airtight container at room temperature for up to 3 days. They may become slightly softer over time. To maintain freshness, add a slice of bread to the container – the bread will absorb any excess moisture.
Refrigerator Storage: Store the cookies in an airtight container in the refrigerator for up to 1 week. They may become slightly firmer in the refrigerator, so let them come to room temperature before serving.
Freezer Instructions: Freeze the cookies in an airtight container for up to 2 months. Thaw them at room temperature before serving. For best results, wrap each cookie individually in plastic wrap before freezing.
Glaze Timing Advice: If you plan to freeze the cookies, it’s best to glaze them after thawing. The glaze may become sticky or dissolve during freezing.
I usually find they disappear so quickly that storing them isn’t even an issue!
