Equipment:

• Mixer
• Bowl
• Mini Muffin Tin
• Optional: Mini Muffin Baking Cups

Ingredients:

• 1 ½ cup flour
• ½ cup sugar
• 1 tsp baking powder
• ½ tsp baking soda
• Pinch of salt
• ½ cup applesauce
• ½ cup greek yogurt
• 2 TBS coconut oil, slightly melted
• 2 eggs
• ½ cup milk
• 4 TBS rainbow sprinkles (Traditional Sprinkles or No Artificial Food Dye Sprinkles)

Step 1: Prep your pan by preheating the oven to 350°F and lightly greasing a mini muffin pan or lining it with paper liners.

Step 2: In a large mixing bowl, whisk together the dry ingredients:

• 1½ cups of flour
• ½ cup of sugar
• 1 teaspoon of baking powder
• ½ teaspoon of baking soda
• and a pinch of salt.
  Mix until everything is evenly combined.

Step 3: In the same bowl, add the wet ingredients:

• 2 eggs
• ½ cup of milk
• ½ cup of applesauce
• ½ cup of Greek yogurt
• and 2 tablespoons of melted (but slightly cooled) coconut oil.
  Stir until the batter is smooth and well incorporated.

Step 4: Gently fold in 3 tablespoons of rainbow sprinkles, saving the rest for topping.

Step 5: Spoon the batter into your prepared mini muffin pan, filling each cup about ¾ full. Sprinkle the remaining 1 tablespoon of rainbow sprinkles over the tops of the muffins for a fun, festive look.

Step 6: Bake for 8 to 10 minutes, or until a toothpick inserted into the center of a muffin comes out clean.

Let the muffins cool in the pan for a few minutes, then transfer them to a wire rack to cool completely before serving (or packing into lunchboxes!). Now you can enjoy the perfect mini muffin!

Make-Ahead and Storage Tips

These muffins are fantastic for meal prepping or packing in advance. You can store them in an airtight container at room temperature for 2–3 days or pop them in the fridge for up to a week. For longer storage, freeze them in a single layer on a baking sheet, then transfer to a freezer-safe bag or container. When you’re ready to enjoy, just thaw at room temperature or microwave for a few seconds. They’re perfect to make in batches and grab on the go!
