Caffeine Mocha Rum Cake

Ready in 45 minutes

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.

Top-ranked recipe named "Caffeine Mocha Rum Cake"


Are you making this? 
3 Cups All-purpose flour
1 1/2 Tsp Baking Soda
3/4 Tsp Salt
3/4 Lbs Bittersweet chocolate chips
1 1/2 Cups Unsalted butter; Cut into pieces
1 1/3 Cups Dark rum
1 Cup Kahlua
2 1/4 Cups Granulated sugar
3 Large Eggs
1 /2 Tsp Vanilla extract
800 Mg Caffeine powder; (optional)
Powdered sugar
Whipped cream
Cocoa powder; for dusting

Original recipe makes 8 Servings



Butter a Bundt or angel food cake pan and dust with cocoa powder

In one bowl, whisk together:

3 cups all-purpose flour

1 1/2 teaspoons baking soda

3/4 teaspoon salt

In the other bowl, mix:

butter, chopped up

3/4 pound chocolate chips

Pro-tip: Place the second bowl on top of a pan of simmering water and stir until it is all melted.

Add the following 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.

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.

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

*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.
