Part 2: Ingredients Breakdown & Step-by-Step Instructions for Peanut Butter Cookies

You don’t need a pantry full of stuff to bake something amazing. These 3-ingredient peanut butter cookies are made with items you probably already have—and the results? Mind-blowing.

Let’s break down each ingredient and walk through the easy-peasy steps to peanut butter cookie perfection.

Ingredient #1: Peanut Butter

Peanut butter is the heart and soul of this recipe.

• Go for creamy peanut butter for a soft, chewy texture.
• Want extra crunch? Use crunchy peanut butter instead.
• Avoid oily natural peanut butter unless you stir it very well—too much oil can cause the dough to separate.
• Use store-bought brands like Jif or Skippy for consistent results.

Ingredient #2: Sugar

The sweet element that gives your cookies that melt-in-your-mouth taste.

• White granulated sugar is the standard—it caramelizes beautifully.
• For a richer flavor and softer texture, try light brown sugar.
• Watching your sugar intake? Coconut sugar is a great swap with a lower glycemic index.

Ingredient #3: Eggs

Eggs bind everything together into a cohesive dough.

• Use 1 large egg for the perfect balance.
• Baking vegan? No problem. Use a flax egg instead (1 tbsp flaxseed + 2.5 tbsp water, mixed and rested for 5 minutes).

Here’s Your Exact Ingredient List

Ingredient	Quantity
Peanut Butter	1 cup (240g)
Sugar	1 cup (200g)
Egg	1 large

Step-by-Step Instruction

Let’s get to the good part: baking! This process is so simple, you’ll probably memorize it after one go.

Step 1: Preheat the Oven

• Set your oven to 350°F (175°C).
• Line a baking sheet with parchment paper or a silicone mat.
• This prevents sticking and makes cleanup a breeze.

Step 2: Mix the Dough

• In a mixing bowl, add:
  • 1 cup of peanut butter
  • 1 cup of sugar
  • 1 large egg
• Stir with a spoon or hand mixer until well combined. The dough should be thick and sticky.
• If it feels too wet, chill it in the fridge for 5–10 minutes.

Step 3: Scoop and Rol

• Use a tablespoon or small cookie scoop to portion out dough balls.
• Roll each into a ball with your hands and place them 2 inches apart on the baking sheet.

Step 4: Flatten with a Fork

• Using a fork, gently press each cookie to flatten it.
• Then press again at a 90-degree angle to make the classic crisscross pattern.

Step 5: Bake

• Pop the tray into the oven.
• Bake for 8 to 10 minutes, or until edges are slightly golden.
• Do not overbake! They’ll continue to set as they cool.

Step 6: Cool and Serve

• Let the cookies cool on the baking sheet for 5 minutes.
• Transfer to a wire rack to cool completely.
• Enjoy warm with milk—or keep them in an airtight jar for later.

💡 Pro Tip: Want to freeze the dough? Shape into balls, place on a tray, and freeze. Once solid, store in a zip-top bag. Bake straight from the freezer—just add 2 more minutes!

Part 3: Tips, Tricks & Variations for Peanut Butter Cookie Success

These 3-ingredient peanut butter cookies are already a winner, but you know what makes them even better? A few insider tips and playful variations. Whether you want them chewier, crispier, or bursting with extra flavor, this part has you covered.

Smart Baking Tips for the Best Results

Even though the recipe’s ridiculously simple, these little tricks can level up your cookie game:

• Use room temperature peanut butter and egg
  Cold peanut butter makes the dough hard to mix. Let it sit out for 10 minutes first.
• Don’t skip the fork press!
  These cookies don’t spread much, so flattening them ensures even baking.
• Line your baking sheet
  Parchment paper or a silicone mat keeps them from sticking—and saves cleanup time.
• Watch the oven like a hawk
  They bake fast. Pull them out when the edges are lightly golden. The centers will firm up as they cool.
• Let them rest
  Don’t move them right after baking—they’ll fall apart. Give them 5 minutes before transferring to a rack.

Pro Tips to Make Them Your Own

• Slightly underbake if you love a chewy center.
• Overbake just a touch for a crispier cookie.
• Add a pinch of salt to boost flavor—especially if your peanut butter is unsalted.
• Chill the dough for 15–20 minutes before baking to reduce spreading and enhance flavor.
• Double the batch—you’ll thank yourself later.

Yummy Peanut Butter Cookie Variations

Feeling fancy or want to switch it up? Here are some must-try twists on the classic:

1. Chocolate Chip Peanut Butter Cookies

• Toss in a handful of mini chocolate chips before baking.

2. Chunky Peanut Delight

• Use crunchy peanut butter and mix in chopped peanuts for next-level texture.

3. Sweet & Salty Version

5. Cinnamon-Sugar Twist

6. Low-Sugar Option

7. Vegan Peanut Butter Cookies

• Replace the egg with a flax egg (1 tbsp flax meal + 2.5 tbsp water).
• Works great with coconut sugar too!

Ingredient Substitutions That Work

• Nut Butter Swap:
  Allergic to peanuts? Try almond butter, cashew butter, or sunflower seed butter (for nut-free!).
• Sweetener Swap:
  Use coconut sugar, monk fruit sweetener, or a keto-friendly sugar substitute like erythritol.
• Egg-Free Binding Options:
  • Flax egg (vegan)
  • Chia egg (similar method)
  • Unsweetened applesauce (¼ cup per egg)

Got questions about these 3-ingredient peanut butter cookies? You’re not alone. Whether you’re troubleshooting, tweaking the recipe, or planning ahead, this FAQ section covers the most common concerns and curiosities from bakers like you.

Let’s get those questions sorted, so your cookies come out just right—every single time.

Can I use natural peanut butter?

Yes, but with a little caution.

• Natural peanut butter (the kind with oil separation) can make the dough oily or crumbly if not mixed properly.
• Stir thoroughly until smooth before using.
• If the dough seems too loose, chill it for 10–15 minutes before shaping.

Can I make these cookies without eggs?

Absolutely!

• Replace the egg with a flax egg: mix 1 tbsp ground flaxseed with 2.5 tbsp water and let it sit for 5 minutes.

Why did my cookies fall apart?

If your cookies are too crumbly or falling apart:

How can I make them less sweet?

Great question!

• Reduce the sugar to ¾ cup and add a splash of vanilla extract or a pinch of cinnamon to balance flavor.
• You can also experiment with coconut sugar, which has a deeper flavor and lower glycemic index.
