Love single serving cakes? Try our chocolate chip protein cookie cake and single serving protein pumpkin cake, too.

Carrot cake might be one of the best desserts of all time, right next to our one bowl chocolate chip cookies and lemon truffles, of course. Yet, as much as we love carrot cake, we don’t always (or have the time) to make an entire cake from scratch. So, we make single-serve carrot cake in a jar instead!
Just combine the ingredients, portion, and bake. In less than an hour you’ve got little cups of heaven just begging to be eaten. You just might never go back to full-sized cake again.
Ingredients You’ll Need
Below is an overview of the ingredients and instructions for this recipe. Please be sure to scroll down to the recipe card below for the complete details!

For the Cake
- Golden Monk Fruit Sweetener – Feel free to use brown sugar or coconut sugar if you prefer.
- Light Olive Oil – Coconut oil or avocado oil will also work.
- Carrot – Use whole carrots, and shred them at home. Do not use pre-shredded store bought carrots as they don’t have enough moisture to add to the cake. Use leftovers to make Moroccan chickpea stew or ham and split pea soup for dinner, too.
- Eggs – These add structure, helping the cake hold together.
- Flavor Enhancers – Vanilla extract, ground cinnamon, and ground ginger create the sweet, spiced flavor we look for in carrot cake.
- Gluten-Free Flour – This forms the base of the cake batter. If you don’t need this recipe to be gluten-free, regular all-purpose flour will also work.
- Baking Powder and Baking Soda – These act as leaveners, helping the cake rise and become soft. We prefer to use baking powder that doesn’t contain aluminum.
Optional Mix-Ins: If you want this carrot cake recipe to be exactly like a full-size version, feel free to fold chopped nuts, raisins, and coconut flakes into the batter, too.

For the Frosting
- Cream Cheese – Use full-fat, brick-style cream cheese.
- Butter – We use salted butter, but unsalted butter works too.
- Powdered Sugar (Confectioner’s Sugar) – This melts into the batter, making it perfectly sweet.
- Vanilla Extract – Adds a subtle vanilla taste.
How to Make Single-Serving Carrot Cake with Cream Cheese Frosting
Before you begin, be sure to preheat your oven, and grease your mason jars with cooking spray.

Note: We like to use six eight-ounce mason jars for adult portions and four-ounce mason jars for mini portions or kids’ sizes!

- Combine the dry ingredients. Whisk the golden monk fruit sweetener, oil, shredded carrots, eggs, vanilla, cinnamon, and ginger in a large bowl.

2. Add the dry ingredients. Add the flour, baking powder, and baking soda. Stir to combine.

3. Fill the mason jars. Pour the cake batter into the greased jars, filling them ⅔ of the way full. Be careful not to overfill, or the batter will overflow!

4. Bake. Arrange the jars on a baking sheet. Then, transfer them to the oven until the cake is golden brown and a toothpick inserted into the center comes out clean.

5. Prepare the frosting. Beat the butter and cream cheese until light and fluffy.

6. Beat. Add the powdered sugar and vanilla, and beat again to combine.
Note: If the frosting is too loose and doesn’t form light peaks, add in an extra ½ cup powdered sugar. Mix until the frosting is stiff enough to form light peaks.

7. Frost. Allow the carrot cake jars to cool completely. Then, frost them with cream cheese frosting or your frosting of choice.

8. Toppings. If desired, top each jar with course sparkling sugar, cinnamon, carrots shreds or pecans. Then enjoy!
Common Questions
Absolutely! You can leave it off completely. Or, swap it for buttercream frosting, meringue frosting, whipped cream, or a dash of powdered sugar.
Leftover jars will stay fresh in the refrigerator for up to 5 days. If possible, store them without the icing, making sure to seal the lid tightly or cover the jars.

Hi,
I am reading that we shoulld not be using mason jars in the oven. They can shatter. Please tell me which mason jars do you use ?
Thank you,

Hi Maha,
I have not heard that before. I have never had a problem with the jars cracking in the oven. The jars are made to get extremely hot while canning so I guess I never thought about it. I am not sure which brand I use as they are hand me down, but I am assuming they are Ball or Kerr brand. I hope you enjoy these carrot cakes.
OMG!! Those sound and look amazing!! Next week is Spring Break here and this is the perfect recipe to make with my daughter! I can’t wait!! Thanks for the easy recipe.
