    slices of kentucky butter cake on a white plate

    This Kentucky butter cake is rich, buttery, and soaked in a sweet vanilla butter sauce that keeps every bite incredibly moist. I've found the magic of this cake is how the warm glaze seeps into the bundt cake while it cools, creating a dense buttery texture that somehow gets even better the next day. The vanilla flavor really shines here, and the crisp sugary edges from the glaze are honestly one of my favorite parts.

    That buttery vanilla glaze soaking into every little hole is exactly why this cake never stays dry for a second!

    "This cake was a huge hit!! One of the best tasting cakes I've ever had. I love a good butter cake and had never made one of my own. I will definitely be making this again."

    Cookies, brownies, sheet cakes, and baked bundt cakes are some of my favorites. Check out my recipe for my favorite chocolate chip cookie recipe. Basically baking anything involving butter and sugar.

    This cake reminds me of my Crack Cake Recipe, that cake is also a bundt cake that is soaked in a butter-sugar syrup but that syrup is made with wine! Make sure to bake that cake recipe next.

    The texture of this cake reminds me of the butter cake at Lazy Dog restaurants. It's moist, buttery, and dense.

    Another reason I love this cake is that it is perfect for a party is that it needs time to sit and really let the butter sauce soak in. So its ideal to make this cake the day before you want to serve it.

    The Ingredients Behind That Buttery Vanilla Flavor

    • Buttermilk: While testing this cake recipe I found that using buttermilk keeps the cake extra tender while balancing all the buttery richness beautifully.
    • Unsalted Butter: Since butter is the main flavor here, I always recommend using good-quality butter because it really comes through in both the cake and glaze.
    • Pure Vanilla Extract: I love using real vanilla extract here because the vanilla flavor is one of the stars of the cake.
    • Butter Sauce: Honestly, the glaze is what makes this cake special. I love how it soaks into the warm cake and creates those sweet buttery edges throughout.

    Poke the cake all over, let it soak in the invert the cake on to a serving platter.

    I like to dust powdered sugar on top of the cake. This cake actually gets better with age, it gives more time of the sauce to really soak in.

    • Total Time: 1 Hour 35 Minutes
    • Yield: 12-16 Slices 1x

    Ingredients

    Scale

    Cake

    • 375 Grams (3 Cups) All-Purpose/ Plain Flour
    • 1 Teaspoon Baking Powder
    • ½ Teaspoon Baking Soda
    • 1 Teaspoon Salt
    • 400 Grams (2 Cups) Granulated/ Caster Sugar
    • 8oz (1 Cup) Unsalted Butter, softened to room temperature
    • 4 Large Eggs, at room temperature
    • 8oz (1 Cup) Buttermilk, at room temperature 
    • 1 Tablespoon Pure Vanilla Extract

    Butter Sauce

    • 200 Grams (1 Cup) Granulated/ Caster Sugar
    • 20z (¼ Cup) Water
    • 4oz (½ Cup) Unsalted Butter
    • 1 Tablespoons Pure Vanilla Extract

    Instructions

    Cake

    1. Preheat oven to 325F/163C and heavily grease and flour a 10-cup bundt pan, set aside while you prepare the filling.
    2. In the bowl of an electric stand mixer or large mixing bowl with a handheld electric mixer beat the butter and sugar together for two minutes, scrape down the sides of the bowl then beat again for another 2-3 minutes. This is not a typo, the butter and sugar need to cream for a long time, don't skip this step.
    3. While the butter is mixing in a small bowl whisk together the flour, baking soda, baking powder, and salt.
    4. Once the butter mixture is light and fluffy add the first egg and mix until no yolk remains. Repeat until all eggs have been added, the mixture may look curdled, which is fine.
    5. Add half of the dry ingredients and gently fold in. In a small bowl combine the buttermilk and vanilla extract. Add the buttermilk mixture, mixing until fully combined, but do not over mix.  Add remaining flour mixture. Do not over mix the cake batter, you don't want to over-develop the gluten. 
    6. Pour into the prepared cake pan and use an offset spatula to spread the batter into an even layer. Bake for 40-50 minutes, or until a toothpick inserted in the center comes out clean with no wet batter, moist crumbs are okay. The internal temperature of the cake should be 210F/99C.
    7. Let the cake cool in the pan for 10 minutes, in this time prepare the sweet butter sauce.

    Butter Sauce

    1. In a small saucepan combine all sauce ingredients and cook over medium heat for 3-4 minutes. Use a skewer or thin metal piece to poke holes all over the cake. Pour the glaze on top and let the cake sit for 30-45 minutes, no longer or you risk the cake becoming stuck. Place a large plate on top and invert the cake onto a serving platter.
    2. Serve with desired toppings and store leftovers in an air-tight container on the counter for up to 4 days.

        Hi Jacqueline, thanks for stopping by. You can totally freeze the cake, once it has baked and the glaze has been poured on let the cake come to room temperature. Once it's at room temperature cover the cake in plastic wrap tightly, do this twice to ensure its fully sealed, then store in the freezer for up to 3 months. Then when you want to serve it I suggest taking it out of the freezer a few hours before. Let me know if you have any further questions or if you try the cake! XX Liz

      Can I add fresh strawberries to the cake? Not to top with but to bake inside?

        Hi Alli, you can definitely try I have never done that before, but if you add too many strawberries it can affect the texture of the cake as the strawberries will add moisture. If anything I would chop the strawberrires then toss them in a tablespoon of flour to coat to try and prevent them from sinking in the cake. Please let me know if you try it how you get on! Thanks.
