Preheat your oven to 350°F (175°C).
Line a jumbo muffin tin with paper liners.
In a large bowl, whisk together the flour, granulated sugar, baking powder, baking soda, and salt.
In another bowl, mix the applesauce, plant-based milk, peanut butter, melted coconut oil, and vanilla extract until smooth.
Add the wet ingredients to the dry ingredients and mix until just combined.
Divide the batter evenly among the muffin cups.
Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
Allow the muffins to cool in the tin for 10 minutes, then transfer to a wire rack to cool completely.
