These mini birthday cake muffins are inspired by the kind of treats kids always get excited about, like those party cake-style muffins you see at the store.
The idea is the same. Soft, bite-sized muffins with sprinkles mixed right in but made at home with simple ingredients.
Some people call them funfetti muffins, others just think of them as muffins with sprinkles, but either way, they have that familiar birthday cake feel.
What I like about this version is how quick and easy it is. They’re ready in about 20 minutes, don’t need frosting, and still feel special enough for birthdays, school treats, or just a fun baking day.
It’s a simple way to make a dessert that feels celebratory without turning on the mixer for an hour.

Tips to Make the Best Mini Party Cake Muffins
Don’t overmix the batter. Stir just until everything is combined to keep the muffins soft.
Use mini muffin liners or grease the pan well. This helps them release cleanly.
Fill the cups evenly. About three-quarters full gives the best rise without overflow.
Save some sprinkles for the top. This keeps the color bright and visible after baking.
Watch the bake time closely. Mini muffins bake fast, so start checking at 8 minutes.
Let them cool before removing. This helps them hold their shape and prevents sticking.
Ingredients You’ll Need
All-purpose flour: 1½ cups
Sugar: ½ cup
Baking powder: 1 teaspoon
Baking soda: ½ teaspoon
Salt: a pinch
Applesauce: ½ cup
Greek yogurt: ½ cup
Coconut oil: 2 tablespoons, slightly melted
Eggs: 2 large
Milk: ½ cup
Rainbow sprinkles: 4 tablespoons
How to Make
Preheat the oven to 350°F (175°C). Line a mini muffin pan with liners or lightly grease it.
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until evenly combined.
Add the eggs, milk, applesauce, Greek yogurt, and melted coconut oil to the dry ingredients. Stir until the batter is smooth and well mixed.
Fold in 3 tablespoons of the rainbow sprinkles.
Spoon the batter into the prepared mini muffin pan, filling each cup about three-quarters full. Sprinkle the remaining sprinkles on top.
Bake for 8–10 minutes, or until a toothpick inserted into the center comes out clean.
Remove from the oven and transfer the muffins to a wire rack to cool completely before serving.
How to Store
Once the muffins are completely cooled, store them in an airtight container at room temperature for up to 3 days.
For longer storage, keep them in the refrigerator for up to 5 days. You can also freeze the muffins for up to 2 months. Thaw at room temperature before serving.
