How To Make Carrot Cake Butter Icing
1. Preheat the Oven and Prepare Pans:
Preheat your oven to 350°F (175°C). Grease and flour your baking pan(s) or line with parchment paper.
2. Mix Dry Ingredients:
In a medium bowl, sift together the flour, baking powder, baking soda, ground cinnamon, and salt. Set aside.
3. Cream Butter and Cream Cheese:
In a large bowl, using an electric mixer beat the softened butter and cream cheese until smooth and creamy.
4. Add Eggs and Maple Syrup:
Add the eggs one at a time, beating well after each addition. Then mix in the maple syrup and vanilla extract until combined.
5. Alternate Adding Dry Ingredients and Milk:
Gradually add the dry flour mixture in three additions, alternating with the milk (start and end with flour). Mix until just combined do not over mix.
6. Fold in Carrots:
Gently fold in the grated carrots using a spatula until evenly distributed.
7. Bake the Cake:
Pour the batter into the prepared pan(s) and smooth the top. Bake for 40-45 minutes or until a toothpick inserted in the center comes out clean.
8. Cool Completely:
Let the cake cool in the pan for 15 minutes, then transfer to a wire rack to cool completely before frosting.
9. Prepare the Butter Icing:
Beat the softened butter and cream cheese together until creamy. Gradually add the sifted powdered sugar, one cup at a time, beating until fluffy. Add vanilla and a pinch of salt and mix until smooth.
10. Frost the Cake:
Once the cake is completely cool, spread the icing evenly over the top (and sides if desired). Slice and serve!
Note
Be patient while mixing the butter and sugar. Rushing this step can lead to gritty icing. Also, always sift your powdered sugar for the smoothest results.
If your kitchen is too warm, refrigerate the icing for 10 minutes and then whip again to regain structure.

Expert Tips For Best Results
➤ Freshly grated carrots add moisture and natural sweetness. Avoid pre-shredded carrots, which can be dry or clump together.
➤ Mix just until the ingredients are combined to keep the cake light and tender. Over mixing can make it dense.
➤ Make sure butter, cream cheese, eggs, and milk are at room temperature for smooth mixing and better texture.
➤ Start testing the cake with a toothpick at 40 minutes to avoid overbanking, which can dry it out.
➤ Let the cake cool fully to prevent the frosting from melting and sliding off.
Serving Suggestions
◆ Serve slices topped with a handful of fresh raspberries, blueberries, or sliced strawberries for a bright, fruity contrast.
◆ Sprinkle chopped toasted walnuts or pecans on top of the frosting for a crunchy texture and nutty flavor.
◆ Lightly drizzle pure maple syrup over the frosted cake slice for an extra touch of natural sweetness.
◆ Serve alongside a dollop of lightly sweetened whipped cream or coconut whipped cream for extra creaminess.
◆ Gently warm a slice in the microwave for 10 seconds and serve with a scoop of vanilla or cinnamon ice cream for a cozy dessert.
Health Benefits Of Carrot Cake Butter Icing
Carrot cake, when made with wholesome ingredients like fresh carrots and natural sweeteners such as maple syrup, offers some nutritional benefits.
Carrots are rich in beta-carotene, fiber, and antioxidants, which support eye health and digestion. The cream cheese and butter in the cake and icing provide calcium and healthy fats, which are essential for bone strength and energy.
While the carrot cake butter icing is a delicious treat and should be enjoyed in moderation, using real ingredients and natural sweeteners can make it a slightly healthier dessert option compared to heavily processed sweets.
Additions And Variations
Additions
1. Add ½ cup of well-drained crushed pineapple to the batter for extra moisture and a subtle tropical sweetness.
2. Stir in ½ to 1 cup of chopped walnuts, pecans, or almonds for a delightful crunch and nutty flavor.
3. Fold in ½ cup of raisins or currants to add bursts of chewy sweetness.
4. Add ½ cup of unsweetened shredded coconut to the batter for a lovely texture and mild coconut flavor.
5. Incorporate 1 teaspoon of finely grated orange zest into the batter or frosting to add a bright citrus aroma.
Variations
1. Use a gluten-free all-purpose flour blend instead of regular flour to make the cake gluten-free.
2. Replace butter with vegan margarine or coconut oil, swap eggs for flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg), and use a plant-based cream cheese for the frosting.
3. Add ½ teaspoon ground nutmeg, ½ teaspoon ground ginger, and ¼ teaspoon ground cloves to the dry ingredients for a more spiced-up flavor.
4. Reduce the maple syrup to ½ cup and the powdered sugar in the frosting to 2 cups for a less sweet cake.
5. Add crushed pineapple (as above) and substitute half the milk with pineapple juice for a tangy twist.
Storage & Make Ahead
Carrot cake butter icing can be made a day or two in advance, allowing the flavors to meld beautifully. Store the cake covered tightly in the refrigerator to keep the icing fresh and prevent drying out.
If you need to keep it longer, wrap the cake layers tightly in plastic wrap and freeze for up to 2 months thaw overnight in the fridge before frosting or serving.
For best texture and flavor, bring the carrot cake butter icing to room temperature before slicing.
