• In the bowl of a stand mixer (or just a large bowl if you're using a hand mixer), combine flour, sugar, cocoa, baking soda, baking powder, and salt. Mix on low until fully blended
• In a separate bowl, combine eggs, sour cream, vegetable oil, and vanilla.
• With mixer on, pour liquid into dry ingredients and mix gently until smooth. Slowly pour in hot/warm coffee while mixer continues.
• Pour an even amount of batter into three prepared cake pans (wax/parchment and shortening or other method as preferred). Bake at 300°F for about 30 minutes or until a toothpick comes out clean.
• Cool cakes for about 5 minutes after removing from the oven. Run a plastic knife quickly around the edges of each cake pan to help release the cake.
• Turn the first cake layer onto a parchment paper covered plate. (Trim any dome off of the cake so layers will stack without cracking.) Do this with the second cake layer and stack parchment/cake on top of first layer. Do the same with the third layer and cover cake with cake carrier lid until cool. Then refrigerate until ready to assemble Garden Party Cake.
• To assemble, spread 1/2 of chilled Chocolate Cremeux over the first layer of cake. Top with a thin layer of Oreo Whipped Frosting. Repeat.
• Frost the top and outsides of the cake with Oreo Whipped Frosting. Garnish with remaining frosting, remaining Oreos, and edible flowers as desired.

Chocolate Cremeux

• Pour chocolate chips in a medium, heat-resistant bowl. Set aside.
• In a medium saucepan, whisk together egg yolks, sugar, and salt until smooth.
• Heat mixture over medium-low while slowly whisking in milk, cream, and vanilla.
• Continue whisking until the mixture reaches 165°F-170°F.
• Pour hot custard over chocolate chips and set for 1-2 minutes to allow the chocolate chips to soften. Stir mixture until smooth. Then, use an immersion blender to emulsify until the mixture lightens in color.
• Cover and cool mixture and then refrigerate until ready to use.

Oreo Whipped Frosting

• In an electric mixer with whisk attachment, fully incorporate sugar and cream cheese.
• Add vanilla to cream. While beating at a medium speed, pour the vanilla cream mixture in a slow stream, stopping often to scrape down the sides.
• Whip until light, fluffy, and spreadable. Remove any frosting you may want to pipe for garnish at this time and place in a piping bag. Then stir 3 cups of chopped Oreos into the frosting (reserve the remainder of the Oreo crumbs for garnish, if desired, or stir those into the frosting as well).
