Ingredients

For the Strawberry Filling:
For the Vanilla Pastry Cream:
Equipment
- 12 x 18 rimmed baking sheet
- Parchment paper
- Cotton kitchen towel or tea towel (NOT terry cloth)
How to Make This Recipe
- Begin by making the strawberry filling. Combine the cut up strawberries, cornstarch, sugar, cornstarch and salt together in a saucepan. Cook over medium heat, stirring frequently, until the mixture begins to bubble. Reduce the heat to medium low and continue to cook until the strawberries are saucy and tender, about 5-7 minutes. Set aside to cool completely or transfer the refrigerator until you are ready to use it.
- Next, make the vanilla pastry cream filling. Whisk egg yolks, butter, cornstarch, half and half, sugar and salt together in a medium saucepan. Place pan over medium low heat and whisk constantly until the butter melts and the mixture becomes smooth and thick, about 3-5 minutes. Strain through a fine mesh strainer into a clean bowl and stir in the vanilla extract. Place a piece of parchment paper directly on top of the pastry cream, followed by a layer of plastic wrap (this prevents the custard from forming a skin). Refrigerate until you are ready to use.
- Finally, make the cake. Preheat the oven to 350 degrees. Spray a rimmed baking sheet (12x18) with baking spray and line the bottom with parchment paper. Spray parchment with baking spray and use your fingers or a pastry brush to make sure the spray is distributed evenly around the top of the parchment paper and the pan.
- Whisk the flour, baking powder and salt together in a medium bowl. Set aside.
- Combine the eggs and sugar together in the work bowl of a stand mixer. Using the whisk attachment, mix on low speed until foamy, about 2-3 minutes. Scrape the bottom and sides of the bowl to make sure everything is incorporated. Increase the speed to medium high and whip until the mixture is thick and pale yellow in color, about 5 minutes. Decrease speed to medium low and slowly add melted butter and vanilla.
- Remove the work bowl from the mixer and, using a fine mesh strainer, sift one quarter of the flour mixture over the top of the cake batter. Gently fold in with a rubber spatula. Repeat three more times with the remaining flour until it is all fully incorporated into the batter.
- Pour mixture into the prepared pan and even out the top. It will be a thin layer of batter. Transfer to the oven and bake until the cake is firm and springs back when touched, about 12-15 minutes.
- Let the cake cool for 5 or 10 minutes in the pan. Run a knife along the edge of the pan and invert the cake onto a clean cotton dish towel (NOT terry cloth) that has been generously dusted with powdered sugar. Peel off the parchment paper that was on the bottom of the cake while it was baking. Starting with the short side of the rectangle, roll the cake in the dusted dishcloth and allow it to rest for 15 minutes.
- Carefully unroll the cake, and spread with the Vanilla Cream Filling, leaving a 1 inch border around the edges. It will be a thin layer. Gently top with the strawberry filling. Carefully reroll the cake around the filling leaving the towel on the counter.
- Trim the ends and transfer to a serving plate (two spatulas, one on either side of the cake, works well for this). Allow to cool completely before dusting with powdered sugar and serving. The cake can be assembled and refrigerated, tightly covered, for several hours prior to serving.
Expert Tips
- Use the right cake recipe. As I said above, this cake is more pliable than most, thanks to the addition of several eggs. This flexibility is important to getting the cake to roll up nicely.
- Use baking spray to prepare the pan, and make sure that it is spread evenly. This cake is baked in a half sheet pan (12 x18) and it will release easily if you spray the pan with baking spray, cover it with a layer of parchment and then spray the parchment. I then use my fingers or a brush to make sure that the parchment and the sides of the pan are evenly coated with baking spray. This will help keep the cake from sticking to the pan or the parchment after it is baked.
- While it is still warm, roll the cake in a dish towel generously dusted with powdered sugar. This is an absolutely critical step. The cake must be rolled while it is still quite warm from the oven. It will crack and break if you try to roll it once it is cool. Since the cake is too warm to assemble with the fillings at first, it is wrapped in a cotton dish towel (NOT terry cloth) until it is cool enough to fill. This sets the rolled shape that we are ultimately looking for. The powdered sugar acts like flour here and keeps the cake from sticking to the towel.
- Once the cake is cool, carefully unroll it and spread your fillings on top, leaving a one inch border around the sides. For this recipe, it works well to put down a layer of vanilla cream and the strawberries on top.
- Carefully roll the cake up, leaving the dish towel behind. This should go smoothly assuming that you were generous enough in your sprinkling of powdered sugar on the towel.
- If any of the filling squeezes out when you roll the cake up, gently wipe away any excess with a paper towel.
- Transfer to a serving platter using a two spatulas, one at the top of the roll and one at bottom, on opposite sides of the cake. This is enough support to get it from the work surface to a pretty serving tray.
- Let the finished cake rest in the fridge for a bit before serving, anywhere from a couple of hours to a day. This will help everything meld together. Be sure to give it a fresh dusting of powdered sugar before serving as some of it may have dissolved during its time in the refrigerator.
FAQs
A rulltårta is basically a Swedish version of the American jelly roll or Swiss roll cake. A thin, tender sponge cake is wrapped around a filling, usually some kind of fruit preserve, pastry cream, whipped cream or some combination of these.
Store the cake tightly covered in the refrigerator until you are ready to serve, anywhere from a couple of hours to 1 day. As I mentioned above, at least a couple of hours of time in the refrigerator is recommended as it helps the cake meld together.
You could use a different fruit filling in place of the strawberries here, or even a high quality store-bought jam. You can skip the cream filling altogether and focus solely on a fruit filling. Or, substitute a layer of whipped cream for the pastry cream.
Be sure to roll the cake in a generously powdered sugar-dusted kitchen towel while the cake is still warm from the oven. This sets the shape of the cake in a roll shape prior to adding the filling and makes it much less likely to crack when you roll it back up with the filling inside. Some recipes call for vegetable oil instead of melted butter which may make your cake more pliant (but sacrifices the buttery flavor). As long as you roll the cake in the towel while it is warm, you should be fine.
