Add peanut butter, eggs, honey, and baking soda to a medium-sized mixing bowl.
Use a large spoon to combine the ingredients well.
Scoop batter into prepared muffin tins about ¾ of the way full. Bake on the center rack for 15-18 minutes. Allow to cool before serving.
Notes
The batter is thick and won't pour into your tins like typical muffin batter.
Your peanut butter should be just peanuts and salt, and require stirring when you first open the jar. The no-stir peanut butter is thicker and won't work well in this recipe.
Instead of using paper liners, you can grease your muffin tins well and scoop the batter directly into them.
Feel free to add chocolate chips to this recipe! They would be a delicious addition.
These muffins freeze very well. Store them in an airtight container in the freezer and let them thaw at room temperature for 20-30 minutes or microwave them before enjoying.
