Chocolate-Hazelnut Roulade - Naturally Gluten-Free

Many autumn tables will be featuring a pumpkin roll, that American classic. But in case you are “pumpkined out” or would just like to offer guests an alternate dessert, I thought I’d post this naturally gluten-free and pumpkin-free hazelnut roulade or Swiss roll.

You will definitely need a half-sheet pan for this cake. Don't attempt it in a smaller rimmed baking sheet or it will overflow. It makes quite a long roll, so I cut it to fit the serving plate I wanted to use, then cut the first servings from the "spare" roll.

As you know, my freezer is my best friend, so I cut two slices and froze them in my favorite glass storage containers so I could tell you how well it works. Just thawed them out at room temperature and had a slice. Perfection! Now I need to bake another one and see how well the whole roll freezes.

If you like, fancy it up even more with frosting. But I like to keep things as low-sugar as possible, so no frosting for me. For more cake-roll tips, check out my Raspberry Swiss Roll post. Do you like rolled cakes? 

Chocolate-Hazelnut Roulade

(Makes 12 to 16 servings)

Adapted from an Almond Roll recipe at King Arthur Flour

The Cake

1 3/4 lightly packed cups (7 ounces/198 grams) hazelnut flour or finely ground hazelnuts
1 tablespoon non-GMO cornstarch

1 1/2 teaspoons non-GMO baking powder
1/4 teaspoon salt, divided
9 large eggs, separated cold, left at room temperature for 30 minutes
3/4 teaspoon cream of tartar
1 cup (7 ounces/198 grams) sugar, divided
1 teaspoon vanilla extract

The Filling

1 1/2 cups (12 fluid ounces/355 ml) heavy whipping cream

1/4 firmly packed cup (1 ounce/28 grams) unsifted powdered sugar

1/4 packed cup (0.75 ounce/21 grams) unsweetened natural cocoa powder
3 tablespoons (1.5 fluid ounces/44 ml) Frangelico or other hazelnut liqueur

1 Preheat oven to 350F/180C/Gas4. Line an 18x13x1-inch half-sheet pan with a piece of parchment with an extra 2 inches on each end for easy removal. Spray parchment and sides of pan with cooking spray. In small bowl, whisk together hazelnut flour, baking powder and half the salt.

2 In bowl of stand mixer fitted with whisk, beat the egg whites, cream of tartar and half the salt on low speed until foamy (might have to use a spoon to mash up clump of cream of tartar). Increase speed to medium and continue beating until trails become visible and bubbles are very small, about 2 to 3 minutes.

3 Increase speed to medium-high and gradually add in 1/2 cup of sugar, about a tablespoon at a time, taking about 2 to 3 minutes. Increase speed a bit and whip until meringue is glossy and medium* peaks form when the whisk is lifted, about 4 to 5 minutes.

* Must beat past soft peaks, but not all the way to stiff peaks.

4 In a 2.5- to 3-quart mixing bowl, using an electric hand mixer, beat the egg yolks with remaining 1/2 cup sugar until pale yellow and fluffy; this takes a few minutes, perhaps 4 or 5. Add the vanilla extract.

5 Give the hazelnut flour mixture another whisking and sprinkle it over the egg yolk mixture. With silicone spatula, gently fold the flour in. Then gently fold in the medium-stiff egg whites, a third at a time, being careful not to deflate them.

6 Gently scrape the batter into the prepared half-sheet pan and quickly spread it evenly. Place a towel (or pair of potholders) on the countertop and drop the pan onto it from a height of about 6 inches two or three times to get out the large air bubbles that would make holes in the cake.

7 Bake for 18 to 20 minutes, just until done. A toothpick inserted in the center should come out clean; the cake should spring back a bit when pressed gently in the center.

8 Use a knife to loosen the sides of the cake from the pan. Using the two ends of parchment paper, lift the cake out of the pan onto a wire rack to cool for a bit.

9 When the cake is nearly cool, make the filling. In a small bowl, whisk together the powdered sugar and cocoa. In medium bowl, whip the cream to soft peaks, sift the powdered sugar and cocoa over the cream and stir until incorporated. Continue whipping the cream until it is quite stiff. Fold in the liqueur.

10 Transfer the cake, still paper-side down, from the wire rack onto the counter with a long side in front of you. Spread the filling evenly over the cake, leaving about a 1.5-inch border at the far side uncovered.

11 Start rolling the cake at the long side nearest you, peeling away the parchment as you go. Place on tray seam-side down and refrigerate for at least 4 hours or up to 1 day.

12 When ready to serve, trim the ends of the roll for a tidier look (and a cook's treat!), place it on an attractive platter, dust with powdered sugar, garnish as you like. Cut into 1- to 1.5-inch slices.
