Does anyone have a recipe for chocolate cake that does not require cocoa powder or a chocolate cake mix?

Things that I do have:
Chocolate Ibarra (Mexican chocolate bar for making Mexican Hot Chocolate)
Scharffen Berger 99% cacao unsweetened dark chocolate
semi-sweet chocolate mini chips
Callebaut Dark Chocolate - 52.3% cocoa solids
Ghirardelli Premium Baking Bar - Semi-Sweet Chocolate
Ghirardelli Premium Baking Bar - 60% Cacao Bittersweet Chocolate
Plymouth Pantry Almond Bark - Chocolate Flavor

I have plenty of milk, butter, eggs, cake flour, sugar, agave syrup, vanilla & almond extract, vanilla beans, buttermilk, plain yogurt, whipping cream, chocolate pudding mix, vanilla pudding mix, baking powder, baking soda, and a box of molten lava cake mix.

Anyone have any ideas how I can make chocolate cake from the above? I am open to things like chilli chocolate cake. I have the cayenne and chilli powder.

I hardly ever use cocoa in a cake. Any of your bars will work, just melt a couple ounces and blend into the batter of pretty much whatever recipe you like.

Here's a simple one you could try:
