Why You'll Love This Recipe

When it comes to desserts, cakes especially, I want easy and quick. That's why I often reach for my crumb bars or cheesecake bars recipes. Easy is where it's at. This One-Bowl Chocolate Cake is just that! You need it in your go-to recipes file. It's as easy as box mix but made from scratch. The fudgy frosting made in a saucepan with just a whisk is out of this world and complements the cake perfectly. You have to try it!

This One-Bowl Chocolate Cake is perfect for a last-minute dessert or if you are craving chocolate cake and need an easy recipe. This one is a keeper!

Ingredients:

  • flour - I used all-purpose flour. If you need to use gluten-free flour, choose one that allows you to substitute at a 1:1 ratio.
  • sugar - I used white, granulated sugar.
  • cocoa powder - Use the best you can get. This is where the chocolate flavor comes from. Dutch-processed cocoa is wonderful here.
  • baking powder and baking soda - The combo of these leavening agents allows the cake to rise and cook properly.
  • buttermilk - I always make my own by combining whole milk (or half and half) and vinegar (or lemon juice). No need to buy it in the store.
  • egg - Binds all ingredients together.
  • oil - I used vegetable oil but canola or even olive oil works here.
  • hot water - This is the secret to making this cake so moist. You can use coffee as well. It will intensify the chocolate flavor.

  • Start by measuring out the flour. To do that correctly, spoon flour into a measuring cup, then level the top. Do not dunk the measuring cup into the flourbag and scoop. You will end up with too much flour.
  • Next, measure out the remaining dry ingredients and whisk everything together.
  • Add wet ingredients and whisk until the batter is smooth, no flour lumps should be visible.
  • Pour the batter into parchment paper or an aluminum foil-lined baking pan (I used an 8" square pan but a round pan will work too). Tap the pan gently against the counter to release any air bubbles, then place it in the oven to bake for 25 to 30 minutes.
  • Check with a toothpick or a dry spaghetti noodle to make sure the cake is done. Next, prepare the frosting.

This recipe is so easy, you won't need a box cake mix anymore. Measure out the ingredients and whisk everything together in one bowl until the batter is smooth. It might seem runny and not thick but no worries, the cake will bake perfectly and every bite will be moist and melt in your mouth.

Recipe FAQs:

Can I use this recipe to make cupcakes?

Yes! To make chocolate cupcakes, divide the batter in the cupcake pan. Bake for 15 to 18 minutes OR until a toothpick inserted into the center of each cupcake comes out clean.

Can I double the recipe to bake in a larger pan?

If you want to use a 13" x 9" pan, double the ingredients. The baking time should be increased to 40 to 45 minutes. But always check the cake with a toothpick to ensure it's done.

Can I use hot coffee instead of water?

Absolutely! Coffee intensifies chocolate flavor so it's a great idea to use it in this recipe. You can use coffee you brewed or mix instant coffee with hot water.

    One of the best things I've ever put in my mouth! Instead of just water I used hot coffee and added a bit of espresso powder to the frosting. I did have to bake it for a few extra minutes, so just be mindful of that. Will definitely be coming back to this!

    Tried this cake today, not the incongruous though. Cake was really easy and came out perfectly. I thought it was a super quick and easy recipe.
    Just made 1 alteration, I added 1 tbsp of coffee to the hot water, otherwise followed the recipe to the ‘T’.

    I've made this recipe many times and love it so much!

    I've tried to make it "healthier" and always screw it up- I'm going back to this one!

    I just wanted to say thank you again, and a very BIG thank you for putting in all the ingredients in the instructions too- this helps so much so I don't have to scroll up with my flour-covered fingers!

    lots of hugs and love, thank you!

      Also, I would love any advance bakers’ knowledge of how to get this cake to bake evenly- I always have an issue with the center being not baked for a while, and it also creates an uneven layer. So if I let the center cook all the way, the outsides is drier than it should be, and vice versa. I checked the temperature of the oven with an oven thermometer and it was accurate, and also tried a real 8x8 baking dish vs the disposable foil one, and the real one made the cake even more uneven- help! I’d really like to master this recipe, but always have issues with these two areas. Thank you!

FAQs

How do you add sweetness to a baked cake? ›

Typically people would cut a cake in half and apply a simple syrup (usually made with sugar and water) to keep the cake moist and occasionally add flavour if it lacks any. Icing - Royal, buttercream, ganache and more. These are your typical icing that you can add to the cake. They usually contain a lot of sugar.

Why is my cake not fluffy? ›

Most cakes begin with creaming butter and sugar together. Butter is capable of holding air and the creaming process is when butter traps that air. While baking, that trapped air expands and produces a fluffy cake. No properly creamed butter = no air = no fluffiness.

What makes cake fluffy and rise? ›

Add a leavening agent to the flour. Most cakes will call for a leavening agent like baking powder or baking soda. These create the bubbles you need for the cake to rise. If the flour you use is self-raising, it already has a leavening agent in it.

What to do if my cake batter is too sweet? ›

Lemon Zest to the Rescue: Grate some lemon zest and sprinkle it on your cake. The zesty, tangy goodness can help balance out the sweetness, turning your cake into a sweet-tart symphony. Whip Up Some Cream: Serve your cake with a dollop of unsweetened whipped cream.

What ingredient gives a sweet flavor in baking? ›

Flavoring agents (molasses, honey, malt, maple sugar)

What happens if you don't put enough sugar in a cake? ›

Without sugar, cake has a raw-like flavor, devoid of nuances that come out as sugar decomposes in caramelization and as it contributes to browning in Maillard reactions. The result of sugar's presence is a “baked” flavor in cake.

What ingredient makes cake fluffy? ›

Leavening Agents

Breads, cakes, cookies, and nearly all baked goods require a leavening agent. These are the key ingredients that make a cake rise. There are two types of leavening agents, chemical (baking soda and baking powder) and biological (yeast).

What makes a cake more dense? ›

On their own, boxed cake mixes have a structure that's loose and airy. But if you add ¼ cup flour or half a box of instant pudding mix, the texture of the cake becomes denser and tighter, ideal for a pound-cake-like consistency that will hold the shape of a Bundt pan.

Does adding an extra egg make cake more moist? ›

Boxed cake mixes tend to be lighter in consistency, but if you're craving that thicker, moister, denser cake, then all you have to do is add an extra egg to your mix. The additional fat in the egg yolk helps create a more tender and moist cake that is full of flavor.

Should you beat eggs before adding to cake mix? ›

Martina says, “Late in the mixing stage, eggs will incorporate better if you lightly beat them before adding to the batter. The finished cake may be slightly shorter than expected, but its flavor and tenderness shouldn't be affected.” For egg-leavened cakes, the eggs are crucial.

Can I use both butter and oil in cake? ›

Oh yes, you sure can. This recipe has a combination of butter and oil to give off that nice buttery taste while keeping it soft and moist at the same time. Cake using pure butter tends to be more dense and dry compared to adding oil into the batter.

What happens if you put too much chocolate in a cake? ›

If you put too much chocolate in a cake, it might become dry and crumbly. The excess chocolate can absorb the moisture from the cake batter, making it difficult for the cake to rise properly. Additionally, too much chocolate can make the cake quite dense and heavy.

What happens if too much sugar is added to a cake? ›

Excess sugar in a recipe produces a cake with a crisp top crust and a tendency to be dry. An 'M' fault may be corrected by using less sugar, less baking powder or more liquid to balance the recipe.

What happens if you put too much flour in cake batter? ›

Too Much Flour

A cake batter with too much flour will be dry, crumbly, and heavy. To avoid this, make sure you weigh your flour instead of scooping it. Although it's quick, scooping with a measuring cup can easily result in too much flour.

What does adding sugar to a cake do? ›

Sugar easily binds with water, which accomplishes two main things. 1) It locks in moisture, keeping your baked goods from drying out; and 2) It inhibits the development of gluten which keeps your cookies, cakes and sweet breads softer.

Why are bakery cakes so sweet? ›

Cake is too sweet in the U.S. when it is commercially made. Doesn't matter by whom, it is universal even by expensive bakeries. The reason is that sweetness enhances flavors, such as chocolate or vanilla.

Why do bakers put sugar water on cakes? ›

The liquid “soaks” into the cake, adding more moisture to prevent the cake from drying out and infusing additional flavor and/or sweetness.
