Ingredients for Chocolate Kahlua Cake

• Milk – I recommend using a dairy milk if possible, but a non-dairy substitution can also work.
• Oil – use an oil without much flavor for best results. I recommend canola oil or coconut oil.
• Flour – all purpose flour works best here, but you could also use a gluten free option like almond flour if you like.
• Sugar – regular granulated sugar is what I used.
• Baking Powder – ensures that the cake rises and takes on a nice, fluffy texture.
• Cocoa – use a high quality cocoa powder for best results. I recommend unsweetened.
• Kahlua – this blend of rum and coffee liqueur provides a unique boozy kick and pairs perfectly with the chocolate flavor.
• Mini Chocolate Chips – semi-sweet chocolate chips are typical, but you could also use milk chocolate or dark chocolate.

Ideas for Toppings

• Hot Fudge Sauce
• Ice Cream
• Mini Chocolate Chips
• Whipped Cream
• Homemade Caramel Sauce

Helpful Tools and Supplies

• Microwave Safe Mug – Make sure the mug you prepare your cake in is safe to put in the microwave. You’ll want a decently sized mug, like these beauties.
• Microwave

How to Make a Mini Kahlua Cake from Scratch

1. In a 12 ounce microwave safe mug, add milk, oil, flour, sugar, cocoa, baking powder, mini chocolate chips, and Kahlua. Stir well to combine, and place in microwave for 1 minute.
   

   Be sure to properly mix your batter, but if you overmix the cake might not fluff up or cook properly.

2. Remove mug from microwave, and if the top is a little jiggly, or looks really shiny, or half way runny, place the mug back in the microwave for 10 seconds.
3. Remove from microwave, and let stand for 2 minutes to cool slightly.
    
4. Top with chocolate fudge sauce, ice cream, whipped cream, or caramel sauce – or whatever your favorite toppings are. Add more chocolate chips on top before serving.

Recipe Variations and Substitutions

• Add a pinch of salt to counteract the rich sweetness and bring out complex notes of the chocolate and coffee flavors.
• For a slightly healthier version of this recipe, use sugar free chocolate chips, a dairy-free milk like almond milk, oat milk, or soy milk, and leave off additional toppings.
• Make this mug cake richer by substituting melted salted butter for the oil.
• Mix in peanut butter chips or white chocolate chips along with the regular chocolate chips for more flavor.
• Pour in a splash of vanilla extract to balance out the chocolate.
• Give your mug cake a deeper, more complex flavor by replacing half of the sugar with brown sugar.
• Pair this rich and hearty dessert with some White Chocolate Dipped Strawberries; the fruity sweetness will help lighten up the fudgy cake!

Expert Tips

• Add the dry ingredients to the mug first. Use a fork or spoon to combine and eliminate clumps.
• Be sure to use a large enough mug. The batter will expand as it cooks, so if you mix everything together and the mug seems full, transfer the batter to a larger mug.
• Give your mug cake a few minutes to cool off, then eat immediately. I don’t recommend storing this in the fridge or freezer. It’s made to be eaten right away!
• Don’t add too much baking powder. If you add too much, it can cause the cake to puff up too much and then collapse. This leads to a dense, chewy texture.
• If you want to double the recipe, be sure to use either a very large mug, or cook in a microwave safe bowl.

Recipe FAQs

Why did my mug cake turn out rubbery?

This can happen if you add too much oil, or if you overcook the cake. Microwaves vary in terms of how fast they cook.

If you find that your mug cake isn’t a texture you like, try starting with a shorter cooking time.

Why are mug cakes so dense?

Because most mug cake recipes don’t include egg, it tends to yield a denser texture. This is perfectly normal.

One of the things that makes mug cakes delicious is their thick, decadent texture! If you love dense and fudgy desserts, I also recommend this Easy Chocolate Fudge as well.

Why is my mug cake rock hard?

This is another result of cooking for too long. Keep in mind that the cake will continue to cook a bit once it’s out of the microwave and sitting.

You can use a toothpick to check if the interior is fairly cooked through.
