Step-by-Step Instructions
Preparation Steps
Start by preheating your oven to 350°F (175°C). This makes sure it is hot when you bake the cookie. In a large bowl, mix 1 cup of creamy peanut butter, 1/2 cup of brown sugar, and 1/2 cup of granulated sugar. Use a whisk to blend until smooth. Next, add 1 large egg and 1 teaspoon of vanilla extract. Beat this mixture until creamy. Now, sprinkle in 1 teaspoon of baking soda and 1/4 teaspoon of salt, mixing well. Gradually fold in 1 1/2 cups of rolled oats until everything comes together. Then, stir in 1 cup of semi-sweet chocolate chips and half of 1/2 cup of crushed graham crackers.
Baking Process
Lightly grease a cast-iron skillet or an oven-safe dish with olive oil or butter. Spoon the cookie dough into the skillet. Spread it evenly while pressing it down gently. Top the dough with 1 cup of mini marshmallows and sprinkle the rest of the crushed graham crackers on top. Place the skillet in your preheated oven and bake it for about 20-25 minutes. Look for golden-brown edges and puffy, toasted marshmallows.
Cooling and Serving Suggestions
After baking, take the skillet out of the oven and let it cool for a few minutes. Slice the cookie into wedges and serve it warm right from the skillet. For a special touch, drizzle some peanut butter or chocolate sauce on top. You can also add extra mini marshmallows for a fun finish. Enjoy this delightful treat with friends and family!
Tips & Tricks
Baking Tips for the Perfect Skillet Cookie
To make the best peanut butter s'mores skillet cookie, follow these tips. First, use creamy peanut butter for a rich texture. Next, measure your ingredients accurately. Too much sugar can make the cookie too sweet.
- Make sure your baking soda is fresh. Old baking soda won’t rise well.
- Whisk the peanut butter and sugars until smooth. This helps the cookie bake evenly.
- Don’t skip the salt; it balances the sweetness.
How to Ensure Even Cooking
To ensure even cooking, here are some key steps. Start by preheating your oven to 350°F (175°C). This ensures the cookie bakes at the right temperature. When you spread the dough in the skillet, press it down evenly.
- Use a cast-iron skillet for better heat distribution.
- Avoid opening the oven door while baking. This can lower the temperature and affect baking.
- Check the cookie around the 20-minute mark. Look for golden edges and puffy marshmallows.
Serving Suggestions to Enhance Flavor
Serving the skillet cookie can be just as fun as making it! Serve it warm, right from the skillet. This keeps it soft and gooey.
- Drizzle extra peanut butter or chocolate sauce over the top for added flavor.
- Garnish with extra mini marshmallows for a festive look.
- Pair it with a scoop of vanilla ice cream for a treat everyone will love.
These tips will help you create a delicious and memorable dessert!
Pro Tips
- Use Room Temperature Ingredients: Allow your peanut butter and egg to come to room temperature for a smoother batter. This helps all ingredients blend more easily, resulting in a better texture.
- Don't Overbake: Keep a close eye on the skillet cookie while baking. It’s best to take it out when it’s just golden around the edges but still soft in the center, as it will continue to cook slightly after removal.
- Customize Your Mix-Ins: Feel free to experiment with different types of chocolate chips or add nuts for extra crunch. You can also swap out mini marshmallows for other toppings like caramel or toffee bits.
- Serve with Ice Cream: For an indulgent twist, serve your peanut butter s'mores skillet cookie with a scoop of vanilla ice cream on top. The warm cookie and cold ice cream create a delightful contrast.
Variations
Flavor Variations
You can change the flavor of your Peanut Butter S'mores Skillet Cookie. Try adding nuts like walnuts or pecans for crunch. You can also swap in dark chocolate chips for a richer taste. If you love caramel, drizzle some over the top before baking. You can even add a sprinkle of sea salt for a sweet and salty mix. Each tweak makes the cookie unique and fun to eat!
Dietary Modifications
If you need gluten-free options, use gluten-free rolled oats and graham crackers. Many stores sell gluten-free marshmallows too. You can also try almond butter instead of peanut butter. This change gives a different flavor while keeping it creamy. Always check labels to avoid hidden gluten in ingredients. These swaps let everyone enjoy this treat!
Mini Serving Options
Mini servings are a great idea for parties or snacks. Use small ramekins to bake individual portions. Just adjust baking time to about 15-18 minutes. This way, each person gets their own warm, gooey cookie. You can also top each ramekin with extra marshmallows or a drizzle of chocolate. It makes for a lovely presentation and a fun experience!
Storage Info
How to Store Leftovers
To keep your peanut butter s'mores skillet cookie fresh, let it cool. Once cool, cover the skillet tightly with plastic wrap. If you use a baking dish, transfer the cookie to an airtight container. Store it at room temperature for up to three days. If you want it to last longer, place it in the fridge. It can stay there for about a week.
Reheating Instructions
When you want to enjoy your leftover cookie, preheat your oven to 350°F (175°C). Slice the cookie into wedges for easy reheating. Place them on a baking sheet lined with parchment paper. Heat for about 10 minutes or until warm. You can also use a microwave. Heat a slice for about 15-20 seconds. If you like melty chocolate, add a few extra chocolate chips on top before warming!
Freezing the Skillet Cookie
If you want to save some for later, freezing is a great option. First, let the cookie cool completely. Then, slice it into wedges. Wrap each slice in plastic wrap, and place them in a freezer-safe bag. This way, they won’t stick together. You can freeze them for up to three months. When you're ready to eat, just thaw them in the fridge overnight and reheat as mentioned above. Enjoy your treat anytime!
FAQs
Can I make this recipe ahead of time?
Yes, you can make this recipe ahead of time. Prepare the dough and store it in the fridge. This way, you can bake it later. Just remember to let the dough sit at room temperature for about 15 minutes before baking. This helps it spread nicely in the skillet.
How do I know when the skillet cookie is done?
The skillet cookie is done when the edges are golden brown. The marshmallows should be slightly toasted. You can also check the center; it should feel firm but not hard. A toothpick inserted in the middle should come out with some crumbs but not wet batter.
Can I use alternative nut butters?
Yes, you can use other nut butters. Almond butter or cashew butter work great. Just make sure the texture is similar to peanut butter. If you use sunflower seed butter, be aware it may change the flavor a bit, but it’s a good nut-free option!
