Frog Commissary Carrot Cake with Pecan Filling and Cream Cheese Frosting is the most incredible carrot cake recipe you will ever eat. This cake goes a long way, it’s very rich!

I love carrot cake. I’ve been harassing my mom for her carrot cake recipe for a few months and she finally told me that she didn’t have one. I asked my sister if she had our mom’s carrot cake recipe and her response was “Mom makes a carrot cake?”. I know that I’m not crazy, I know that at some point she made me a carrot cake and it was insanely good. My mom used to own a catering business and has a big binder of recipes from those days and I was convinced that it was in there. It wasn’t.
Turns out the cake that I was thinking of is a recipe from a closed Philadelphia restaurant called The Frog Commissary. (I think that they still might have a catering business and do the food at the Franklin Institute.) This cake had a reputation and when the restaurant closed, the carrot cake lives on. If you were married in Philadelphia in the ’80s, there was a good chance this was your wedding cake.

Why You Will Love Carrot Cake
Carrot cake is a great cake for a beginner baker. You can make the cake batter by hand – no mixer needed. It’s hard to dry out because of the moisture from the oil and grated carrot. If you want to really elevate this cake, make the pecan cream filling. You need to make the filling the day before, it needs to set up. It’s really easy and is a twist on the classic carrot cake.
This is a SERIOUS cake. This is a dense cake. It weighs about 47 pounds. You can get a lot of slices out of it, it is very rich, a little goes a long way. I made this cake and it sent to my husband’s office and it lasted about four minutes. I send a lot of baked goods up there and they can be a tough crowd, but this cake was a favorite.
Carrot Cake Ingredients
Pecan Cream Filling
- 1 1/2 cups sugar
- 1/4 cup flour
- 3/4 teaspoon salt
- 1 1/2 cups heavy cream
- 3/4 cup butter
- 1 1/4 cups chopped pecans
- 2 teaspoons vanilla
Carrot Cake
- 1 1/4 cups vegetable oil
- 2 cups sugar
- 2 cups flour
- 2 teaspoons cinnamon
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- 1 teaspoon salt
- 4 eggs
- 4 cups grated carrots
- 1 cup chopped pecans
- 1 cup raisins
Cream Cheese Frosting
- 8-ounce package cream cheese, room temperature
- 1/2 cup butter, room temperature
- 4 cups powdered sugar
- 1 teaspoon vanilla
- Pinch salt

Instructions
Step 1: The day before you are going to assemble the cake, make the pecan cream filling.
Step 2: In a heavy saucepan, add sugar, flour, and salt. Give a whisk and slowly stir in cream. Add butter. Cook and stir over low until the butter has melted. Let simmer for 20 to 30 minutes, or until the mixture turns golden brown. Remove from heat and let cool to lukewarm.
Step 3: Add pecans and vanilla and stir through. Let cool completely and keep in the fridge overnight.
Step 4: If it is too thick to spread the next day, put in the microwave for 10 to 15 seconds.
Step 5: To make the cake, preheat oven to 350°. Spray (3) 8-inch with baking spray.
Step 6: In a large bowl, whisk oil and sugar until smooth. Set aside.
Step 7: In another bowl, sift together flour, cinnamon, baking powder, baking soda, and salt.
Step 8: Add half of the dry ingredients into the sugar mixture. Mix until incorporated. Alternate eggs, one by one with the remaining flour mixture. Add carrots, pecans, and raisins and mix until just combined.
Step 9: Pour batter evenly into the three pans.
Step 10: Bake for 30 to 40 minutes, or until a toothpick comes out clean. Let cool in pans for 10 minutes, then turn out and cool completely on a wire rack.
Step 11: To make the cream cheese frosting, beat the cream cheese and butter until light and fluffy in the bowl of an electric mixer. Add half of the sugar and beat for two minutes. Add remaining sugar, vanilla, and salt. Continue to beat until very fluffy.
Step 12: To assemble, place the first layer on your cake plate. Add cream cheese frosting to a piping bag fitted with a large round tip. Pipe a thick layer of frosting around the edge of the cake. Fill in the ring with pecan cream filling. Repeat with the next layer. Top with the third cake layer and cover the top with cream cheese frosting.

Tips for Frog Commissary Carrot Cake
- Make the pecan filling the day before. It needs some chill time in the fridge to set up.
- The original recipe calls for toasted coconut around the sides of the cake. I wanted to leave mine naked, but coconut goes really well with this cake.
- I don’t like raisins, so I leave them out add more pecans.
- You can prepare this cake a few days ahead of time. It keeps really nicely.
How to Store Carrot Cake
You can make this cake a few days before you want to serve it. It keeps really well. I usually keep it covered and store it in a cool, dry place. If you store it properly, it will taste great even a full week after baking!
This cake also freezes really well. You can keep it in the fridge in an airtight container for up to 3 months.

Hi Denise, you should be able to find it on Amazon. I believe the latest edition is form 2002.
Hi- are the carrots truly grated, or are they shredded? I plan to use a food processor and I have an actual grating disk. Thanks!
Hi Beth, I would recommend grating them if possible. They need to be quite small.
I made this carrot cake for Easter and it was so good…my family members were taking 2 pieces at time, one to eat and then one to take home so they could eat it at work the next day 😊 I had leftover pecan filling and used it to frost the brownies I baked…OMG !! Aaaaaammmmaaazzzing
That’s fantastic to hear Colleen! 🙂
The most delicious carrot cake! Truly a labor of love but made again yesterday and love even more! I have an original cookbook and this recipe is my favorite.
So glad to hear you loved this recipe!
I have been baking this cake for many years- my old Commissary Cookbook is falling apart. Love seeing the recipe here so that I can continue to access the recipe. I have grated the carrots and in a pinch, put them through my food processor. It’s all good! The leftover pecan filling can be warmed slightly and put over ice-cream. Great recipe and thanks for reminding me!
Thanks so much for reading!
Hi Bree, love everything you do on your Insta!! I’m a good cook, but I am very new and intimidated to baking! I have a question as to win the cream filling prep the night before is added to the rest of the ingredients. Is the cream filling referred to as the sugar mixture in the recipe? When is that cream filling mixed in with the other wet and dry ingredients? Thank you!!
Hi Cindy! No worries, baking can be a lot of fun once you get the hang of it! The pecan cream filling is made separately and is used to fill the cake layers during assembly. The “sugar mixture” in the cake instructions is just for the cake batter. You’ve got this, and I’m sure your cake will turn out amazing!
I would give this wonderful cake 10 stars. Thank you for posting the recipe. I followed your instructions and while it took me much longer than an hour it was so worth it.
So glad to hear! This recipe is definitely one of our most popular. Thanks for reading and leaving a review!
