Carrot cake has always been one of those desserts that feels a little special. It’s rich, incredibly moist, warmly spiced, and topped with creamy frosting that melts in your mouth.

How to Make It: Step-by-Step Instructions
Step 1: Prep the Pans and Oven
Preheat your oven to 350°F (177°C). Line two 8-inch round cake pans (or one 9×13-inch baking dish) with parchment paper circles, then lightly spray the sides with non-stick avocado oil spray.
Step 2: Finely Shred the Carrots
Wash and peel 2 medium carrots. Use the fine holes of a box grater to grate 1.5 cups (loosely packed) of fresh carrots. The Pro Secret: Do not use coarse pre-shredded packaged carrots from the grocery store. They are too dry, tough, and thick to melt into the cake batter properly.
Step 3: Whisk the Dry Blend
In a large mixing bowl, combine 2.5 cups of superfine blanched almond flour, 3 tablespoons of coconut flour, 2 teaspoons of baking powder, 1.5 teaspoons of ground cinnamon, 1/2 teaspoon of ground ginger, 1/4 teaspoon of ground nutmeg, and 1/2 teaspoon of fine salt. Whisk thoroughly for 30 seconds to break up any lumps in the flour.
Step 4: Beat the Wet Ingredients
In a separate medium bowl, use a hand mixer to beat 3/4 cup of melted (and cooled) unsalted butter with 3/4 cup of granulated monk fruit allulose sweetener until combined and slightly pale. Add 4 large room-temperature eggs one at a time, beating well after each addition. Stir in 1.5 teaspoons of pure vanilla extract.
Step 5: Merge, Fold, and Pour
Pour the wet liquid blend into the dry flour bowl. Use a rubber spatula to fold the batter together until a thick dough forms. Fold in the 1.5 cups of finely shredded carrots and 3/4 cup of chopped pecans. Divide the thick batter evenly between your prepared cake pans, smoothing the tops with the back of a spoon.
Step 6: Bake and Cool Completely
Bake at 350°F for 28 to 33 minutes. The cake layers are done when the edges are lightly golden and a wooden toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 20 minutes before turning them out onto a wire rack. Crucial Step: The cake layers must be 100% completely cool before frosting, or the butter and cream cheese in the frosting will melt and slide off.
Step 7: Whip the Sugar-Free Cream Cheese Frosting
In a medium bowl using an electric mixer, beat 8 ounces of softened full-fat block cream cheese and 1/2 cup of softened unsalted butter together for 2 minutes until light and fluffy. Gradually add 3/4 cup of powdered monk fruit sweetener and 1 teaspoon of pure vanilla extract. Beat on high speed for another full minute until smooth and spreadable.
Step 8: Assemble and Chill
Place the first cooled cake layer onto a serving plate. Spread a generous layer of frosting over the top. Stack the second layer on top and coat the top and sides with the remaining frosting. Garnish with remaining chopped pecans. Chill the cake in the refrigerator for 30 minutes before slicing to let the frosting set firm.
Pro Tips for Best Recipe
Use Block Cream Cheese Only: Always purchase full-fat cream cheese sold in foil-wrapped blocks, not spreadable tub cream cheese. Tubs contain added water and milk, which will turn your frosting into a runny liquid.
Fine Shred is Mandatory: Always use the fine shredding side of your grater. Finely shredded carrots release just enough juice to hydrate nut flours while softening completely in the heat of the oven.
Toast Your Pecans First: Before folding chopped pecans into the batter, spread them on a baking tray at 350°F for 5 to 7 minutes until fragrant. Toasting brings out natural oils and enhances the nuttiness of the cake.
Chill Before Serving: Grain-free, butter-based cakes taste significantly better when chilled for an hour before eating. Chilling firms up the crumb and allows the spices to marry together.
Storage
- To Store: Because this cake features fresh cream cheese frosting, it must be kept refrigerated. Place leftover slices in an airtight cake carrier or cover loosely with plastic wrap. Store in the fridge for up to 5 days.
- To Freeze: You can freeze unfrosted cake layers or sliced frosted cake. Wrap individual frosted slices tightly in plastic wrap, then store them in a freezer zip-top bag for up to 3 months. Thaw overnight in the refrigerator before serving.
Frequently Asked Questions
Are carrots keto-friendly?
Yes, in moderation! While raw carrots contain natural sugars, using 1.5 cups distributed across an 12-slice cake adds less than 1.5 grams of net carbs per serving.
Can I make this cake in a 9×13 pan instead of round layers?
A 9×13-inch baking pan works well. Pour all the batter into a parchment-lined 9×13 pan and bake at 350°F for 30 to 35 minutes until a toothpick comes out clean.
Why is my cream cheese frosting too soft?
This occurs if the cream cheese or butter was melted rather than softened, or if the cake layers were still warm when frosted. Pop the frosting bowl in the fridge for 20 minutes to firm back up before spreading.
Can I substitute coconut oil for the butter?
Yes! You can substitute melted coconut oil for the butter in the cake batter for a dairy-free option. However, keep butter in the frosting for the best texture and flavor.
