These party cake muffins are perfect to celebrate any ordinary day—or as a really fun way to start a child's birthday. Be gentle when stirring in the sprinkles to limit the color running.
Preheat the oven to 375 degrees F. Grease a 24-cup mini muffin pan with nonstick spray.
In a large bowl, whisk together the applesauce, butter, eggs, milk, and vanilla extract.
In a medium bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
Gently stir the dry ingredients into the wet ingredients. VERY gently fold In sprinkles. Do not over-mix or they may start to bleed.
Divide the batter among the prepared muffin pan, using about 1 1/2 tablespoons batter in each cup. Top with additional sprinkles if desired.
Bake for 12-14 minutes, or until a cake tester inserted into the center comes out cleanly. Transfer to a wire rack, using a knife around the edges to loosen if needed, and let cool.

Notes
Once cooled, store in an airtight container at room temperature for up to 3-5 days. Or you can freeze in a freezer bag with as much air removed as possible for up to 3 months. Thaw overnight in the fridge or at room temperature.
You can gently fold the sprinkles into the batter in the bowl or use a toothpick or cake tester to stir some into each muffin cup. The latter option usually results in slightly less bleeding but both will work.
I usually top each muffin with extra sprinkles before putting into the oven.
