These Mini Carrot Cake Muffins are everything you love about a classic carrot cake packed into a perfectly portioned, bite-sized treat. Loaded with freshly grated carrots, warm cinnamon, nutmeg, and ginger, each muffin bakes up incredibly moist and tender in just 12 minutes. Topped with a tangy, fluffy cream cheese frosting, they're ideal for brunch spreads, parties, lunchboxes, or any time you want a quick and crowd-pleasing sweet bite.
Preheat oven to 375°F (190°C). Line a 24-cup mini muffin pan with mini muffin liners or grease each cup thoroughly with nonstick cooking spray.
Peel and wash 2 medium carrots, then grate them on the fine side of a box grater to yield 1½ cups. Do not squeeze out the moisture — it keeps the muffins tender.
In a medium bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, nutmeg, and ginger until evenly combined. Set aside.
In a large bowl, whisk together the granulated sugar, brown sugar, eggs, vegetable oil, and vanilla extract until smooth and slightly pale, about 1 to 2 minutes.
Add the dry ingredients to the wet ingredients and fold gently with a rubber spatula just until no dry streaks remain. Do not overmix.
Fold in the grated carrots and chopped walnuts or pecans (if using) until evenly distributed throughout the batter.
Using a small cookie scoop or tablespoon, fill each mini muffin cup about ¾ full. You should fill all 24 cups evenly.
Bake on the center rack for 11 to 13 minutes, until the tops are set and a toothpick inserted in the center comes out clean or with a few moist crumbs.
Let muffins cool in the pan for 5 minutes, then transfer to a wire rack and cool completely before frosting.
Beat the softened cream cheese and butter with an electric mixer on medium speed until smooth and lump-free, about 2 to 3 minutes. Add vanilla, then beat in the sifted powdered sugar until fluffy. Add milk one tablespoon at a time to reach a smooth, pipeable consistency.
Spread or pipe frosting onto each completely cooled muffin. Optionally garnish with a pinch of cinnamon, finely chopped walnuts, or a small carrot curl before serving.
Notes
Always use freshly grated carrots — pre-shredded carrots from a bag are too dry and coarse and will result in a denser, less moist muffin.
Do not squeeze the moisture out of the grated carrots. That natural liquid is what keeps these muffins tender during and after baking.
Use room temperature eggs and oil for a smoother batter and a more even bake.
Measure flour by spooning it into the measuring cup and leveling off — scooping directly from the bag packs in too much flour and can make the muffins dense and dry.
Do not overmix once the dry ingredients are added. Stir only until the flour disappears or the muffins will turn out tough.
Cool muffins completely before frosting. Even slightly warm muffins will cause the cream cheese frosting to melt and slide off.
Make-ahead tip: Bake muffins up to 2 days in advance and store unfrosted in an airtight container at room temperature. Make the frosting the day before and refrigerate; frost before serving.
Storage: Frosted muffins must be refrigerated in an airtight container and will keep for up to 5 days. Unfrosted muffins can be stored at room temperature for up to 2 days.
Freezing: Freeze unfrosted muffins in a single layer, then transfer to a freezer-safe bag for up to 3 months. Thaw at room temperature and frost after thawing.
To make regular-sized muffins, use a standard 12-cup muffin pan filled two-thirds full and bake at 375°F for 18 to 22 minutes, checking for doneness with a toothpick.
