Preheat the oven to 350 degrees F. Butter and flour 2 (8-inch) round cake pans.

Sift the flour, sugar, cocoa, baking soda, baking powder, and salt into the bowl of an electric mixer fitted with a paddle attachment.

In a large measuring cup or small bowl, combine the buttermilk, oil, eggs, and vanilla.

With the mixer on low speed, slowly add the wet ingredients to the dry ingredients.

With the mixer still on low, add the hot coffee and stir just to combine, scraping the sides and bottom of the bowl with a rubber spatula. Don’t overmix; the batter should be very thin and runny.

Divide the batter among the prepared pans and bake for 35 to 40 minutes, until a cake tester comes out clean.

Cool in the pans for 30 minutes, then carefully turn them onto a cooling rack to cool completely. Freeze or refrigerate until firm to the touch.

In the bowl of a stand mixer fitted with the paddle attachment, mix together the sugar and butter.

Mix on low speed until well blended, then increase the speed to medium and beat for another 3 minutes until ultra light and smooth.

Add in the strawberry preserves, salt, and vanilla and beat on medium for 1 minute.

Add about 1/4 teaspoon gel food coloring, if using, and beat until the buttercream is evenly colored. Add more coloring if desired.

Place the first cold cake layer, flat side up, on a flat surface or cake pedestal.

Using an offset spatula, spread about 1/3 of the frosting all over the top of the cake.

Place the second cake layer on top, flat side up, and spread a very thin coating of frosting all over the top and sides of the cake to make a crumb coating.

Freeze or refrigerate the cake until the frosting is firm.

Once the frosting is firm, spread the remaining frosting evenly over the cake, scraping away excess frosting and smoothing imperfections with the offset spatula.

Garnish with sprinkles and chocolate-covered strawberries before serving if desired.
