Preheat oven to 350°F.

In a bowl, mix flour and baking soda.

In another bowl, whisk applesauce, honey, egg, and peanut butter until smooth.

Combine wet and dry ingredients, stirring until just mixed.

Divide batter into a greased mini muffin tin, filling two-thirds full.

Bake for 12 minutes, until a toothpick comes out clean.

Cool on a wire rack before serving or frosting.
