Preheat oven to 325°. Lightly spray a 12-inch cast-iron skillet with baking spray with flour.
In a large bowl, beat cake mix, eggs, tart cherry juice, and oil with a mixer at medium speed until thick and smooth, about 2 minutes, stopping to scrape sides of bowl. Fold in chopped cherries. Spread batter into prepared pan.
Bake until a wooden pick inserted in center comes out clean, 30 to 35 minutes. Let cool on a wire rack for 5 minutes. Using a fork, poke holes in warm cake at 1-inch intervals.
In a medium bowl, stir together gelatin and 1 cup boiling water until gelatin is dissolved. Slowly pour all over cake. Let cake stand for 30 minutes, and then cover and refrigerate until cold, about 4 hours or up to 3 days. 5. Just before serving, in a large bowl, beat cream, maraschino cherry juice, and confectioners’ sugar with a mixer at high speed just until stiff peaks form. Spread onto cake. Garnish with chocolate and cherries, if desired.
Notes
Use a vegetable peeler to shave a bar of chocolate for garnish.
*We used Duncan Hines Devil’s Food Cake Mix and R.W. Knudsen Just Tart Cherry Juice.
