Introduction: Caffeine Mocha Rum Cake

About: I like to make things for the internets. I also sell a pretty cool calendar at supamoto.co. You'll like it.

Coffee cake is cake that goes with coffee, but what about substituting the cake for the coffee? What if you were able to get all of the caffeine and cake at the same time? And here we are with Caffeine Mocha Rum Cake. The whole cake here has 800 mg of caffeine in it, roughly 8 cups of coffee's worth. So eat a 1/8th slice and you're good to go! It's a bit of an overload and really tasty.

Step 1: Ingredients and Supplies

Ingredients
  • cocoa powder for dusting
  • 3 cups all-purpose flour
  • 1 1/2 teaspoons baking soda
  • 3/4 teaspoon salt
  • 3/4 pound bittersweet chocolate chips
  • 3 sticks (1 1/2 cups) unsalted butter, cut into pieces
  • 1 1/3 cup dark rum
  • 1 cup kahlua
  • 2 1/4 cups granulated sugar
  • 800 mg caffeine powder* (optional)
  • 3 large eggs
  • 1 1/2 teaspoons vanilla extract
  • powdered sugar
  • whipped cream
Supplies
  • Mixer
  • Two bowls
  • Bundt or angel food cake pan
Preheat oven to 300F

* Caffeine powder is not something to be played with, the cake is great without it. I used a very sensitive scale to measure this out, but one teaspoon is the equivalent of 20 cups of coffee so guessing is bad. If you were to do this, I'd recommend crushing up No Doz instead for a more easily measured amount.

Step 2: Prep the Pan

Butter the pan and dust with the cocoa powder

Step 3: Two Bowls

In one bowl, whisk together:
  • 3 cups all-purpose flour
  • 1 1/2 teaspoons baking soda
  • 3/4 teaspoon salt
In the other bowl, add:
  • butter, chopped up
  • 3/4 pound chocolate chips
Place the second bowl on top of a pan of simmering water and stir until it is all melted. The picture here with the sticks of butter? Totally wrong. Chop it up for faster time to cake.

Step 4: Add Booze and Mix

Add this to the melted chocolate mixture and stir:
  • 1 1/3 cup dark rum
  • 1 cup kahlua
  • 2 1/4 cups granulated sugar
  • 800 mg caffeine powder
With a mixer, then add in:
  • flour mixture
  • 3 large eggs
  • 1 1/2 teaspoons vanilla extract
When completely mixed, pour into the cake pan and put in the middle of the oven. Bake until a tester comes out clean, about 1 hr and 50 minutes.

Step 5: Take Out and Serve

When the cake is fully baked, take it out of the oven and let it cool before removing from the pan. Dust with powdered sugar, cut and serve it up with whipped cream.

If you want to eat more, be sure to wait a bit to see how caffeinated you are before taking a second slice.

Enjoy!
