I geared towards black forrest cake, instead ended up with 2 moist cherry-chocolate cakes. Took to work, several people swore it was rum cake. The plan was for 4 layers. This cake has 3 layers. Chocolate and cherry flavors blended nicely after refrigerating overnight. Overall sweetness of cake was flat, next time will use 1 to 1-1/2 tsp salt. Also will divide eggs, add yokls first, then incorporate beaten egg whites into batter to make lighter or fluffier Will replace oil with extra virgin coconut oil. Will blend concentrated cherry juice with cherry filling. Mistakenly used 3 cups flour instead of 2, as sugested. One cake should yield 4 thin layers light enough to work with. Cherry sparkling water perhaps did not impart additional flavor, happened to have and fit the theme. This was a lot of fun. Thank you!
