• 3 tablespoons All-Purpose Flour (gluten-free flour can be used at a 1:1 ratio)

Directions:

How to Make Mug Peanut Butter Cookie

1. Prepare Your Mug: Start by choosing a microwave-safe mug. A larger mug works best as the cookie will expand while cooking.
2. Mix the Wet Ingredients: In your mug, combine the softened butter and creamy peanut butter. Use a fork or a small whisk to mix them together until the mixture is smooth.
3. Add the Sugar: Stir in the sugar until it is well combined with the peanut butter mixture.
4. Incorporate the Egg Yolk: Next, add the egg yolk to the mixture. If you are opting for a vegan version, you can replace the egg yolk with a flax egg. To make a flax egg, mix 1 tablespoon of ground flaxseed with 2.5 tablespoons of water and let it sit for about 5 minutes until it thickens.
5. Add the Dry Ingredients: Sprinkle in the flour and mix until everything is well incorporated. The batter will be a little thick, and that’s okay!
6. Stir in the Milk: Pour in the milk and the vanilla extract. Stir everything together until you have a uniform batter.
7. Add Peanuts or Chocolate Chips: Finally, fold in the chopped unsalted peanuts or chocolate chips if you’re craving extra sweetness.
8. Microwave Time: Microwave your mug cookie on high for about 40-60 seconds. The exact time may vary depending on your microwave. Keep an eye on it to avoid overcooking.
9. Cool and Enjoy: Once cooked, let it cool for a minute or two, as it will be very hot. Then, dig in straight from the mug or transfer it to a plate.

How to Serve Irresistible Peanut Butter Mug Cookie

To serve your Peanut Butter Mug Cookie, you can simply enjoy it straight from the mug. This makes it an easy and fuss-free treat. However, if you want to elevate your dessert experience, consider these ideas:

• A Scoop of Ice Cream: Add a scoop of vanilla or chocolate ice cream on top while the cookie is still warm. The ice cream will melt just enough to create a delightful combination of hot and cold flavors.
• Drizzle Chocolate or Caramel: Drizzle some melted chocolate or caramel sauce over the cookie to enhance its sweetness and provide a gourmet touch.
• Fresh Fruit: Serve with fresh banana slices or strawberries for a fruity contrast.
• Whipped Cream: Top it off with a dollop of whipped cream for extra creaminess.

How to Store Irresistible Peanut Butter Mug Cookie

Since this recipe is for a single serving, it is best enjoyed fresh and warm right after cooking. However, if you have leftover batter (which is uncommon), or if you find yourself making more than one:

1. Refrigerate: Store any leftover batter in an airtight container in the fridge for up to 1 day. When you want to enjoy your cookie again, simply reheat it in the microwave for 15-20 seconds.
2. Leftover Cookie: If you have leftover cooked cookie, you can store it in an airtight container at room temperature for up to 2 days.

Tips to Make Irresistible Peanut Butter Mug Cookie

• Don’t Overcook: Microwave ovens can vary in power, so start with 40 seconds and check your cookie. If it’s still too gooey, add 10 more seconds, but avoid overdoing it to keep that delicious chewy texture.
• Use Softened Ingredients: Make sure your butter is softened before mixing. This will help create a smooth batter. If you forget to leave your butter out, you can microwave it in 5-second increments until it’s soft but not melted.
• Experiment with Toppings: Get creative! Add any toppings you love, such as M&Ms, chopped chocolate, or a sprinkle of sea salt for a sweet-salty combination.
• Gluten-Free Option: You can easily make this mug cookie gluten-free by using a 1:1 gluten-free flour blend.

Variations

While the classic Peanut Butter Mug Cookie is hard to beat, you can try these fun variations:

1. Nut-Free Option: Substitute peanut butter with sun butter or any other nut-free alternative for those with nut allergies.
2. Chocolate Lovers: Add 1 tablespoon of cocoa powder to the mixture for a chocolate peanut butter cookie.
3. Add Spices: For a twist, try adding a pinch of cinnamon or a dash of nutmeg to the mixture for additional flavor.
4. Banana Peanut Butter Cookie: Replace half the peanut butter with mashed banana for a fruity twist!
5. Candy Bar Mug Cookie: Incorporate bits of your favorite candy bar into the cookie dough to add a fun flavor.

FAQs
