    For this week’s Tried & True Tuesday, I am sharing a new flavor for the Crazy Cake recipe, Coffee & Kahlúa – I have BOTH the cake and mug cake versions for you!

    I was busy in the kitchen on Friday, experimenting with the recipe for a party over the weekend.  I am so excited to share this new version – it turned out wonderful. Everyone loved the cake. Just like the original, the cake turned out super moist and delicious. With a just hint of coffee and Kahlúa, it’s a yummy twist on the Great Depression era recipe.

     

    Be sure to check out all of my Crazy Cake Flavors!

    Please Note: Original post date, June 18, 2013. This is not a sponsored post, I have no affiliation with the Kahlúa, I am just a fan.

     

    Coffee & Kahlúa Crazy/Wacky Cake

    Ingredients

    • 1 1/2 Cups flour (all-purpose)
    • 3 Tbsp. cocoa (unsweetened)
    • 1 Cup white sugar
    • 1 tsp. baking soda
    • 1/2 tsp.  salt
    • 1 tsp. white vinegar
    • 1 tsp.  pure vanilla extract
    • 5 Tbsp. vegetable oil
    • 3/4 Cup brewed coffee (cold or room temperature)
    • 1/4 Cup Kahlúa
    Directions
    Preheat oven to 350 degrees F.

     

    Mix first 5 dry ingredients in a greased 8″ square baking pan. Make 3 depressions in dry ingredients – two small, one larger (see #3 in photo below). Pour vinegar in one depression, vanilla in the other and the vegetable oil in third larger depression. Pour coffee and Kahlúa over all.  Mix well until smooth.

     

    Bake on middle rack of oven for 35 minutes. Check with toothpick to make sure it comes out clean. Cool. Top with your favorite chocolate frosting or sprinkle with powdered sugar. Enjoy!


    FROSTING RECIPES
    • For a great easy chocolate frosting (my favorite) head over to THE YUMMY LIFE,for a ONE MINUTE FROSTING recipe!
    • For a dairy free frosting recipe, head over to Oh She Glows for a simple 2-ingredient chocolate fudge frosting recipe!

    Tips

    If you don’t have/like Kahlúa, use 1 cup of coffee.

     

    You can double the recipe, just use a 9×13 baking pan.

     

    You can also mix the batter in a bowl for neater, easier mixing AND for cupcakes (adjust baking time for cupcakes). Be sure to follow the directions the same way – mixing the dry ingredients then making the depressions for the wet ingredients.

     

    Although I have not used Gluten Free flour mixes for this recipe, many people have use it for the Original Chocolate Crazy Cake, and it turns out wonderful! “Yes it is yummy and very moist. It even works with gf flour mixes!”

     

    {The tutorial picture above is from my original Crazy Cake post. The steps are the same. Instead of water in step 5, pour 3/4 cup of coffee and 1/4 cup of Kahlúa}

    COFFEE & KAHLUA CRAZY CAKE IN A MUG

    Print Recipe 
    Save recipe to Pinterest

     

    Ingredients
    • 5 Tablespoons flour (all-purpose)
    • 4 1/2 Tablespoon sugar
    • 2 teaspoons cocoa (unsweetened)
    • 1/4 teaspoon baking soda
    • Dash of salt
    • 1/2 teaspoon white vinegar
    • 1/4 teaspoon pure vanilla extract
    • 2 teaspoons vegetable oil (or canola)
    • 4 Tablespoons brewed coffee (cold or room temperature)
    • 1/2 Tablespoon Kahlúa
    Directions
    Using a large microwave safe mug, spray the inside with non-stick cooking spray.

     

    Next, mix the first 5 dry ingredients in the mug.  After mixing well, make 3 depressions in dry ingredients.  Pour vinegar in one depression, vanilla in the other and the vegetable oil in third depression.  Pour coffee and Kahlúa over top.  Mix well until smooth using a fork.

     

    Place in microwave and cook on high for *2 minutes, uncovered. Check with toothpick to make sure it comes out clean.  Be sure not to over cook!  Top with whatever you like – powdered sugar, frosting, chocolate chips, whipped cream. Enjoy hot or cold.

     

    TIPS
    Each microwave cooks differently, adjust time accordingly!  One person made the cake in 1 minute 40 seconds, and another in 1 minute 20 seconds.  If you overcook the cake, it may ruin it. Be sure to watch as it bakes.

     

    If you want a neater mug cake, mix the cake batter in a small bowl, then pour the batter in the mug.

     

    You can add mini chocolate chips to the batter for a super rich chocolate cake…or do what I did, throw some on top after you make it, while it’s still warm! Mmm, mmm good.

     

    Coffee & Kahlua Crazy Cake in a Mug
    The tutorial picture above is from the original Chocolate Crazy Cake in a Mug. The steps are the same.  In place of water, use 4 Tablespoons of coffee and a 1/2 Tablespoon of Kahlúa.

     

    Thanks so much for stopping by!
    Cheers!

      I made this cake exactly as directed. It tastes just like chocolate cake- the coffee and Kaluha don't really come through. It's also a bit more dry than the other wacky cakes I've tried from you site (which are fantastic!). I am making a second cake today. Any suggestions to make this less dry/more coffee and Kaluha-ish? Thank you and Merry Christmas!

      Delicious cake! I used my homemade Kahlua for this recipe. I also made the One Minute Frosting but used heavy cream and coffee extract instead for the frosting. My husband said it was a bit rich, he's not a huge fan of chocolate the way I am. I thought it was perfectly rich, full of flavor and moist.

      Don't care for coffee. I know… Says hint of coffee. Could I split coffee and Kahula 50/50? I understand alcohol bakes out and it is flavor only. Just asking everybody's opinion. Thank you

      Hi Ellen – The baking time will vary from oven to oven, but in a 9×13 baking dish, baking time would anywhere from 30 to 40 minutes. Keep an eye on your cake starting at 30 mins.

      I made these cupcakes last night for a party… as a gluten free dessert… and they were a smashing success!!!! I substituted with all purpose GF flour and they were super moist and rose just like cupcakes are supposed to! LOVE THEM!!! (Also doubled the batch. It made 30 cupcakes… and only took about 21 minutes to cook.)

      Have you ever doubled this cake and put it in a bigger pan? If so, wondering what the cooking time might be…

      This was delicious and easy! I had all the ingredients and it came together quickly. Next time I will cut the baking time by a few minutes so it will be extra moist. Karen M.

      Have you ever tried to substitute applesauce for the oil? I usually do that for a low or non-fat version, but I'm not sure if it would work with this.
