Essential Equipment for Making 3 Ingredient Sugar Free Peanut Butter Cookies

You don’t need a fancy kitchen for this one! All you really need are a few basic things you probably already have:

  • A good old mixing bowl for, well, mixing!

  • Some parchment paper. Trust me, this makes cleanup SO much easier.
  • A fork. Yep, just a regular fork for those classic criss-cross marks!

Step-by-Step Guide: Crafting Your 3 Ingredient Sugar Free Peanut Butter Cookies

Alright, let’s get these cookies into the oven! Honestly, the hardest part is waiting for them to bake.

Preheating and Preparing Your Baking Sheet

First things first, let’s get that oven ready. You want to preheat it to 350°F (that’s 175°C). While it’s warming up, grab your baking sheet and lay down some parchment paper. This is my little secret to super easy cleanup and making sure your cookies don’t stick one bit. It just makes life easier, trust me!

Combining the Cookie Dough Ingredients

Grab your mixing bowl and toss in the peanut butter, the egg, and your sugar substitute. Now, just mix it all up until it’s nicely combined. You don’t need to go crazy here – just mix until everything is incorporated and you’ve got a dough that looks like, well, cookie dough! Overmixing can sometimes make them a bit too tough, so be gentle.

Shaping and Flattening Your 3 Ingredient Sugar Free Peanut Butter Cookies

Now for the fun part! Take about a tablespoon of the dough and roll it into a little ball between your hands. Place the balls on your prepared baking sheet, leaving a little space between them so they don’t spread into each other. Once they’re all lined up, take your fork and gently press down on each one, then press again in the opposite direction to make those classic criss-cross marks we all love. Try to make your balls about the same size so they bake evenly!

Baking to Golden Perfection

Pop that baking sheet into your preheated oven. We’re going to bake these for about 10 minutes. You’re looking for the edges to be just lightly golden. Ovens can be a little finicky, so keep an eye on them. They might not look completely “done” when you pull them out, but they’ll firm up as they cool.

Cooling and Resting Your Cookies

This step is crucial! Let those cookies hang out on the baking sheet for a few minutes after you take them out of the oven. They’re still a bit fragile when warm! After they’ve cooled slightly, gently transfer them to a wire rack to cool completely. This is when they’ll get that perfect texture – slightly chewy on the inside, a little crisp on the edges.

Tips for Perfect 3 Ingredient Sugar Free Peanut Butter Cookies

Okay, so these cookies are super easy, but like anything, a few little tricks can make them *chef’s kiss* perfect! Following these tips will seriously up your cookie game:

  • Go Natural with Your Peanut Butter: If you can, use a natural peanut butter where the only ingredients are peanuts and maybe a little salt. It tends to be a bit softer and creamier, which makes the dough easier to work with and the cookies even more tender. The kind with the oil separated on top? That’s your best bet!
  • Don’t Overbake! This is a big one. Seriously, pull these cookies out when they’re just *lightly* golden around the edges. They’ll continue to cook a bit on the hot baking sheet. If you bake them until they look super brown, they’ll end up dry and crumbly instead of that perfect chewy texture we’re after. Trust me on this!
  • Sweetness Control is Key: Everyone’s taste buds are different, right? The recipe calls for 1/2 cup of erythritol, but if you’re sensitive to sweeteners or prefer a less sweet cookie, start with a little less, maybe 1/3 cup. You can always mix in a tiny bit more to the dough if needed, but you can’t take it out!
  • Uniform Balls for Even Baking: I know I mentioned it before, but it’s worth repeating! Try really hard to make your cookie dough balls the same size. This ensures they all bake at the same rate, so you won’t have some burnt and some underdone.
  • Press Gently with the Fork: When you’re making those cute criss-cross patterns, don’t press too hard. You just want to flatten them a bit and create the pattern. If you press too much, you can squeeze out the air and make the cookies dense. We want them delightfully chewy, not like hard little pucks!
  • Room Temperature Egg is Best: While not strictly necessary, using a room temperature egg helps everything combine more smoothly. If you forget to take it out of the fridge, just pop it in a small bowl of warm water for about 5 minutes.

Following these little pointers will make a huge difference. You’ll be whipping up perfect batches of these amazing sugar-free peanut butter cookies every single time!

Ingredient Notes and Substitution Ideas

Let’s chat a little more about these few, but mighty, ingredients because they really do make a difference in these 3 Ingredient Sugar Free Peanut Butter Cookies!

Peanut Butter: My absolute favorite is natural peanut butter – the kind where you have to stir it because the oil separates. It’s usually just peanuts and salt, and its texture is perfect for these cookies. It makes them wonderfully soft and chewy. If you use a processed peanut butter with added sugars or oils, your cookies might turn out a bit different, maybe a little greasier or less flavorful. Give the natural stuff a try!

Sugar Substitute: Erythritol is my go-to because it bakes really well and has a clean taste. But if you don’t have erythritol, no worries! Allulose or a good granulated monk fruit blend will work too. Just be aware that different substitutes can have slightly different sweetness levels, so you might want to taste your dough (yes, it’s safe!) and adjust a bit. You can use less if you’re sensitive to sweeteners, or maybe add a tiny bit more if you have a super sweet tooth!

Storing Your Delicious 3 Ingredient Sugar Free Peanut Butter Cookies

Alright, you’ve made these amazing little gems, and now you want to keep them fresh, right? Good news! Storing these 3 ingredient sugar free peanut butter cookies is super simple. Just pop them into an airtight container. They’re perfectly happy sitting at room temperature for about 3-4 days. Honestly, though, they disappear so fast, you probably won’t even need to worry about them lasting that long!

Frequently Asked Questions About Sugar Free Peanut Butter Cookies

Can I use a different nut butter?

You sure can! While peanut butter is classic, these cookies are super adaptable. Almond butter or cashew butter would work beautifully. Just make sure you’re using a natural, unsweetened version similar to the peanut butter for the best results. The texture might be a little different, but the flavor will be delicious!

Why are my cookies spreading too much?

Oh, the dreaded cookie spread! It usually happens if your peanut butter is too oily or if the dough is too warm. Using natural peanut butter is best because it tends to be a bit thicker. Also, make sure your oven is properly preheated. If they still spread a lot, try chilling the dough balls in the fridge for about 15-20 minutes before you bake them. That usually does the trick!

Can I make these vegan?

You’re so close! The only non-vegan ingredient here is the egg. To make these vegan, you can easily substitute the egg with a flax egg. Just whisk together 1 tablespoon of ground flaxseed with 3 tablespoons of water and let it sit for about 5 minutes until it gets gelatinous. Use that in place of the egg, and voila – vegan sugar-free peanut butter cookies!

What kind of sugar substitute is best?

Erythritol is my favorite for these because it has a pretty neutral flavor and bakes well. However, you can totally use other granulated sugar substitutes like xylitol (just be careful if you have pets, it’s toxic to dogs!), allulose, or a monk fruit blend. Some substitutes are sweeter than others, so you might need to adjust the amount slightly to get the sweetness just right for your taste buds.
