Billot Log Cake a.k.a. Raspberry Buttercream Log

With the Canada Day weekend just a few days away I decided to create a dessert for our nation’s 146th birthday. It is based yet again on another popular snack cake from my childhood, Vachon’s Billot Log cake.

A Billot Log is mini sponge roll cake filled with raspberry jelly and sweet frosting and rolled in coconut. We’ve previously featured another Vachon inspired cake in our Jos Louis Cake.

The red and white coloring of the little treats is reflective of the Canadian flag. So with some sweet fresh raspberries in the fridge I decided to take inspiration from it and create a homage to the Billot Log cake.

Desiccated coconut in white ceramic bowl.

Fine cut dried (desiccated) unsweetened coconut is the type I use in this recipe but you can use sweetened if that is what you have on hand.

I made it in particular for my son Noah who absolutely loves raspberries and specifically asked  for a cake with lots of frosting. He thought this cake was the best thing ever.

Fresh raspberries should be used in this recipe. Frozen will melt into the frosting as they thaw & make it runny.

I know he’ll be asking for it again and I wouldn’t be surprised if it makes another appearance as his birthday cake later this summer.

For those of you unfamiliar with the Billot Log, I thought this YouTube “un-boxing” of the snack cake was quite amusing.  Happy Canada Day!

Billot Log Cake a.k.a. Raspberry Buttercream Log

Prep Time: 40 minutes
Cook Time: 20 minutes
Total Time: 1 hour

Billot Log Cake is inspired by the famous Vachon snack cake & is perfect for Canada Day. It's a sponge cake roll with buttercream raspberries & coconut.


For the Sponge Cake

  • 1 cup flour
  • 1 tsp baking powder
  • 6 eggs separated, room temperature
  • 1/4 tsp cream of tartar
  • 1 cup sugar, separated in 2 portions of  1/2 cup each.
  • 1 1/2 tsp vanilla extract

For the Vanilla Buttercream Frosting

  • 4 cups icing sugar (powdered sugar)
  • 1 cup butter
  • Approximately 2 tbsp milk
  • 1 tsp vanilla extract

You will also need

  • 1 1/2 cups fresh raspberries
  • 3/4 cup raspberry jam or jelly
  • 2 tbsp water
  • 3/4 cup unsweetened or sweetened dried coconut


To prepare the Sponge Cake

Line the bottom of a 12 x 18 inch jelly roll pan or ridged cookie sheet with parchment paper cut to it's exact size. Do NOT grease the pan. Preheat oven to 300 degrees F.

Sift together the flour and baking soda and set aside.

Beat egg whites and cream of tartar until foamy.

Add 1/2 cup sugar gradually until egg whites come to soft peaks. Set aside in another bowl.

Beat the egg yolks and 1/2 cup sugar until foamy and thickened.

Fold beaten egg yolks into the beaten egg whites along with the vanilla for only a few turns.

Slowly and gradually folding in the flour and baking powder mixture very gently BY HAND using a rubber spatula until just incorporated into the whipped egg white mixture. I mix in the dry ingredients in 3 equal portions. Do not over mix, you just want the flour to be incorporated; over mixing will deflate the egg whites and result in a tough textured final product.

Spread the batter evenly into the prepared pan and bake for 20-25 minutes until the center springs back when touched.

Cool in the pan for about 15 minutes.

Run a sharp knife around the edge of the pan to release the cake.

Cover the top of the cake with another sheet of parchment paper and invert onto the counter top.

Beginning at the shortest side, loosely roll the cake up between the two sheets of paper, letting it rest with the edge seam on the bottom.

Let it cool completely. This technique will allow the cake to be more easily rolled later without cracking when the filling is added.

To prepare the Vanilla Buttercream Frosting

In the bowl of an electric mixer blend together the icing sugar and until the butter is well incorporated but the mixture is still a bit crumbly.

Add the milk and vanilla extract.

Add the milk a little at a time until the frosting is light, fluffy and smooth. I like to beat the frosting for an additional 5 minutes once I get the consistency correct in order to beat in more air and make it lighter and creamier.

To construct the cake.

Unroll the sponge cake and remove the top parchment paper. Spread the frosting evenly over the cake. Sprinkle the surface of the frosting evenly with the raspberries.

Starting at a short side of the cake, begin to roll the cake up, removing the bottom parchment paper as you go. The parchment paper is a great help in rolling the cake.Let the cake rest on a serving plate with the seam side down.

Mix together the raspberry jam and water. Heat the jelly and water in the microwave or in a small pot on the stove until it is smooth and evenly blended.

Brush the heated jelly all over the surface of the cake roll.

Finally sprinkle the entire surface of the cake roll with

Chill the cake in the refrigerator for a couple of hours before serving. I like to make this cake the day before to give time for the raspberries to meld with the sugar in the frosting making it even better.

Here it is middle of the night and I'm trying to make something for my girl to take to a school concert tomorrow and I don't know what to do. Baking soda or baking powder? Going for maximum loft, I'm leaning toward baking soda. Hopefully it will turn out, but I definitely would like to know which it is in the end, baking powder (in recipe list) or baking soda (in the recipe instructions).

Here's my theory: Writing out ingredients is mechanical, so I can see losing focus and accidentally substituting powder for soda. Conversely, writing out instructions requires active engagement and therefore the potential for error is reduced. The author's reference to baking soda then, though it represents a divergence from the recipe list, is most likely the ingredient one is meant to use.

Am I right? Fingers crossed, this jelly roll will turn out, but I'll check back regardless. :)
