Preheat the oven to 325 degrees F. Generously mist three 8-inch diameter by 2-inch high cake pans with nonstick spray, and line with circles cut from parchment paper.
Place the sugar, flours, cocoa, baking powder, baking soda, and salt in a large mixing bowl, and whisk to combine.
Cut the butter into smaller pieces and add it to the dry ingredients. Mix on low speed until the mixture resembles damp sand (30 seconds to 1 minute).
Add the eggs, one at a time, scraping the bottom and sides of the bowl with a silicone spatula after each addition.
When all of the eggs are fully incorporated, add the Greek yogurt, vanilla, and almond extract, and beat on medium speed for about 60 to 90 seconds, to aerate the batter and strengthen the cake's structure.
Divide the batter evenly between the three prepared pans, and bake for 30 to 40 minutes, or until a toothpick inserted in the thickest part of the cake comes out clean or with one or two moist crumbs. Cool completely, then fill and frost.
FROSTING
Place the cherries, jam, and ½ teaspoon of the almond extract in a medium bowl and toss to coat. Set aside.
Place the cream cheese and powdered sugar in a large bowl and beat on medium-low speed until smooth.
Turn the mixer down to medium-low speed and pour the heavy cream down the side of the bowl in a very slow and steady stream.
When all the cream has been added, turn the mixer up to medium-high and whip until the frosting holds stiff peaks.
Fold in the vanilla extract and remaining ½ teaspoon of almond extract.
ASSEMBLY AND GLAZE
Place one layer of chocolate cake on a serving platter.
Spread half the cherries on the cake, and top with about ⅓ of the whipped cream frosting.
Top with the second cake layer, and repeat, topping with the third layer.
Frost the cake with the whipped cream frosting.
Heat the cream in a small pot until barely simmering.
Place the chocolate in a small bowl, and pour the hot cream over the chopped chocolate, allowing it to stand for 5 minutes.
Whisk the chocolate and cream together until fully incorporated.
Whisk in the corn syrup and vanilla, and carefully pour the glaze in a slow stream around the perimeter of the cake, allowing it to drip down the sides.
Garnish with fresh cherries, chocolate curls, and powdered sugar.
Notes
To make chocolate curls, just run a veggie peeler down the side of a chocolate bar.
