A tender moist cake layered with sweet, crunchy meringue, crisp almonds and a tangy strawberry-rhubarb filling. Delicious!
For the filling
- 10 oz rhubarb (about 2 large stalks), trimmed and thinly sliced (about 2 3/4 cups)
- 10 oz strawberries (about 2 cups), sliced (and about 2 oz more for the top of the cake; see below)
- 2/3 c (4.7 oz or 133 g) granulated sugar
- 2 tbsp (10 g) instant tapioca
- 2 tsp (10 ml) lemon juice
For the cake layers
- 4 oz (8 tbsp or 225 g) unsalted butter, at room temperature; more for greasing the pans
- 4 oz (1 c or 125 g) cake flour, sifted
- 1 tsp (5 g) baking powder
- Table salt
- 1 1/4 c (8.8 oz or 250 g) granulated sugar, divided into 1/2 c (3.5 oz or 100 g) and 3/4 c (5.3 oz or 150 g) portions
- 4 large eggs, separated, at room temperature
- 1 tsp (5 ml) pure vanilla extract
- 3 tbsp (45 ml) milk
- 2 oz (1/2 cup or 45 g) sliced, untoasted almonds
- 2 oz (about 1/2 c) fresh strawberries, sliced, for the top of the cake
Make the filling
- In a large, heavy saucepan, combine the rhubarb, strawberries, sugar, tapioca, and lemon juice. Stir well and let stand for about 15 minutes to soften the tapioca. Place the saucepan over medium heat and bring to a simmer, stirring often, until the mixture begins to thicken (about 5 minutes).
- Reduce the heat to low and cook, stirring occasionally, until the mixture is jamlike and has reduced to about 1 3/4 cups (about 30 minutes). Transfer to a bowl, let cool, cover, and then refrigerate until cold.
Make the cake layers
- Position a rack in the center of the oven and heat to 350°F or 325°F Convection.
- Generously butter two 8-inch round cake pans (springform if you have them), line the bottom with parchment, and then butter the parchment.
- In a small bowl, whisk the flour, baking powder, and a pinch of salt.
- In a small bowl, stir together the vanilla and milk.
- In the bowl of a stand mixer fitted with the whisk attachment, cream the butter and 1/2 cup of the sugar at high speed until light in color and texture, scraping down the bowl occasionally (about 5 minutes). Add the egg yolks one at a time, and beat at medium speed to incorporate. Scrape down the bowl and then beat at high speed until the mixture is bright yellow (about 2 minutes).
- Sift half of the flour mixture over the creamed butter; beat just until incorporated. Pour in the milk mixture; mix at low speed until just blended. Sift the remaining flour mixture on top and then beat just until incorporated. Do not overmix.
- Divide the batter between the two cake pans, smoothing the tops evenly with an offset spatula.
- In a clean stand-mixer bowl with a clean whisk attachment, beat the egg whites at medium speed until frothy (about 2 minutes). Gradually sprinkle in the remaining 3/4 cup sugar, scraping down the bowl as needed. Once all the sugar is added, beat the whites at high speed until glossy, medium peaks form (about 6 minutes). The meringue will look and feel quite dense.
- Divide the meringue between the cake pans and spread with the back of a spoon to cover most of the cake, but leaving about 1/2″ from the edge of the pan uncovered; do not smooth the tops. Sprinkle the almonds over the meringue, and then bake until puffed and lightly browned (about 25 minutes). Let the layers cool in their pans on a rack; the tops will sink considerably.
- While the cake is still warm, run a knife or small offset spatula around the sides of the cake layers to loosen them from the pans. After the layers are cool, carefully remove the parchment. If you’re careful, you can do this without inverting the layers. Choose the less attractive layer and gently spread about 2/3 of the the rhubarb filling over it. Cover with the other cake layer, meringue side up; spread the remaining filling on the top layer. (The cake may be assembled to this point a day ahead; cover loosely with plastic wrap and refrigerate.)
- To serve, top with fresh strawberries, and slice gently with a serrated knife.
- The filling takes a while to cool, so leave lots of time for that; the actual assembly of the cake is quite quick.
- The meringue cake really puffs up while baking, and then subsides into hilly, crisp, chewy deliciousness while cooling. Springform pans are tall enough to contain the meringue at its highest.
