Vegan Chocolate Tart With Salted Oat Crust

Preparation

1. Crust:

   Step 1

   Preheat oven to 350°F. Pulse oats, whole wheat flour, coconut oil, agave, cocoa, salt, and cinnamon in a food processor until oats are coarsely ground and mixture looks like wet sand.

   Step 2

   Firmly press into bottom and up the sides of tart pan. Bake until crust is golden brown and smells toasty, 20–25 minutes. Transfer to a wire rack; let cool.

2. Filling and Assembly:

   Step 3

   Dissolve espresso powder in 3/4 cup very hot water in a food processor. Add cocoa and let sit 5 minutes. Add melted chocolate, agave syrup, vanilla, 2/3 cup coconut oil, and 2/3 teaspoon kosher salt and process until mixture is very smooth and thick, about 30 seconds.

   Step 4

   Scrape filling into cooled tart shell and smooth top (if making tart in a rectangular shell, you may have a little filling left over; save for another use, like truffles). Tap tart lightly against counter to pop any air bubbles in filling.

   Step 5

   Cook oats and remaining 1 teaspoon coconut oil in a small skillet over low heat, stirring constantly, until oats are toasted, about 3 minutes. Gradually add half of demerara sugar, stirring constantly, until sugar is melted, then remove from heat and stir in remaining demerara sugar just to coat. Season with kosher salt; let oat mixture cool.

   Step 6

   Scatter oat mixture over tart, sprinkle with sea salt, and chill until filling is set, at least 1 hour.

   Step 7

   Cut chilled tart into slices with a dry, hot knife; let sit at room temperature 15–20 minutes before serving.

3. Do Ahead

   Step 8

   Tart can be made 2 days ahead. Once filling is set, cover and keep chilled.
