These muffins are so easy to make and they taste great. It takes only about 5 minutes to prepare the batter. Even though there is no flour in the batter, the muffins bake up like traditional muffins and have a similar texture. They aren’t too sweet, so they are perfect for an afternoon snack or maybe even breakfast.


One of the reasons this recipe is so easy is because of the simple ingredient list. All you need are:

  • Peanut Butter
  • Eggs
  • Baking Powder
  • Erythritol
  • Sugar-Free Chocolate Chips


I used erythritol granular to make these muffins. You can also replace with other similar sugar substitutes, like Swerve, but make sure they are also granular.

Sugar-Free Chocolate Chips

Even though it looks like I used mini chocolate chips, I actually used regular-sized ones. The chocolate does sink into the batter a little when it bakes, so it’s better to use regular-sized ones. I found the mini version sunk in too much. My favorite is Lily’s semi-sweet chocolate chips.

Texture of the Muffins

Even though the muffins have no flour, they have a similar texture and appearance as traditional muffins made with flour. They have a tighter crumb, like most muffins, but are still fluffy and moist.

How to Make Keto Peanut Butter Muffins

  • All the ingredients except the chocolate chips are whisked together in a bowl until the batter is completely smooth and no egg streaks remain.
  • Half of the chocolate chips are stirred into the batter.
  • The batter is then added to a mini muffin pan lined with muffin liners. I definitely recommend adding the liners, otherwise the muffins are difficult to remove if baked directly into the pan.
  • The remaining chocolate chips are placed on top of each muffin. The batter should be thick enough that the chocolate chips shouldn’t sink down. Adding them to the top will keep them near the surface as they bake.
  • Bake for about 12 minutes in an oven preheated to 350F . The muffins are ready to be enjoyed once cooled.

  • 1/4 cup creamy unsweetened peanut butter
  • 1/2 tsp baking powder
  • 2 large eggs
  • 3 tbsp erythritol granular
  • 1/4 cup sugar free chocolate chips


  • Preheat oven to 350°F. Line your mini muffin tin with muffin liners.
  • In a large mixing bowl, add all ingredients except chocolate. Mix with a whisk until batter is smooth and no egg streaks remain. Stir in half of the chocolate.
  • Fill cupcake liners 2/3 full with batter. Sprinkle a few chocolate chips onto each muffin. The batter should be thick enough so that the chocolate does not sink down. Do not push the chocolate chips down as they will sink in a little when the muffins are baking.
  • Bake for about 12 minutes until muffin tops look completely cooked and a toothpick inserted comes out clean.


  • The muffins are not overly sweet. If you prefer sweeter, cupcake-like muffins you can add more sweetener to the batter.
  • If you plan on omitting the chocolate, definitely add more sweetener as the chocolate contributes to the sweetness of the muffins.
  • I used this Wilton mini muffin pan* and these mini muffin cups*.
  • I used Lily's semi-sweet chocolate chips* and erythritol granular*.
  • Mini muffin tins come in a few different sizes. My cooking directions were based on the usage of the Wilton mini muffin pan. If your mini muffin molds are slightly bigger or smaller, you will have to adjust the cooking time accordingly.

  1. Perfect morsel to have with coffee!

  2. Are these eggy? Do they even remotely taste like egg or have that egg texture?
