Gluten-Free Chocolate Tea Cake

Preparation

1. Step 1

   Preheat oven to 325°. Lightly coat a 8½x4½" loaf pan with nonstick spray. Pulse cocoa powder and 1 cup almonds in a food processor until very finely ground, about 1 minute.

   Step 2

   Microwave chocolate and ¼ cup water in a microwave-safe bowl in 15-second intervals (or heat in a heatproof bowl set over a saucepan of simmering water), stirring occasionally, until melted. Whisk in oil and salt, then almond mixture and half of granulated sugar, then egg yolks.

   Step 3

   Using an electric mixer on high speed, beat egg whites and cream of tartar until frothy. With motor running, gradually add remaining granulated sugar; beat egg whites to firm peaks.

   Step 4

   Gently fold egg whites into chocolate mixture in 2 additions, folding just until incorporated each time. Scrape batter into prepared pan; top with chopped almonds and raw sugar. Bake cake until top is firm when gently pressed and a toothpick inserted into the center comes out with a few moist crumbs attached, 50–60 minutes. Transfer to a wire rack and let cake cool in pan 15 minutes. Turn out onto rack and let cool completely.

   Step 5

   Do Ahead: Cake can be baked 4 days ahead. Store tightly wrapped at room temperature.
