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.

How to make a one-bowl chocolate cake?

  • 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 crunchy texture to a cake? ›

If whole nuts seem a little too jarring, you can sprinkle chopped nuts on top of a decorated cake, or even mix them right into the frosting. Chopped peanuts or sliced almonds would work well mixed into buttercream, adding just the right amount of crunch in each bite without being so hard that you might break a tooth.

What happens when you add sour cream to a box cake mix? ›

According to food-science blog Food Crumbles, sour cream can help thicken a cake and make it moister. And, since sour cream contains fat, your cake will also be richer. Per baking blog Liv for Cake, you may want to start by adding about 1 cup of sour cream.

Does sour cream make a cake more moist? ›

Sour cream is one of the fattiest dairy products; the extra fat content (for example, adding sour cream to a cake instead of milk) will make the cake moister and richer, says Wilk. "Fat, in any form (butter, lard, cream, etc.) shortens gluten strands, which essentially leads to the most tender baked goods," she adds.

What makes a cake crispy? ›

Fat content: Fat in the batter or dough will contribute to the crispy texture by preventing the dough from becoming too moist a.

What is the perfect cake texture? ›

For best texture, beat filling ingredients at medium-low speed. Beating at high speed adds air to the batter; longer, slower beating yields a pleasantly dense cake.

Does adding an extra egg to cake mix make it more moist? ›

Add an Extra Egg

Most cake mixes call for two to three eggs. Just one more egg will add extra moisture, fat, and a little protein, which means the cake will be softer and less likely to overbake and dry out in the oven.

What gives sweetness to cakes? ›

Sugar can give foods the sweet taste we know and love – but there is much more to it. It also performs many other essential functions in cookies, cakes, and other baked goods. We all know that sugar is essential for baking—after all, it's what makes sweets taste sweet.

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

Sugar adds more to cakes than a sweet taste. It also affects the texture, colour and how well they keep. A light and airy cake texture is usually down to tiny air bubbles becoming trapped around the rough edges of the sugar crystals, which expand as the cake cooks.

Can I use mayo instead of sour cream in cake mix? ›

Mayo is a great sour cream substitute. It can be used as a 1:1 replacement in both baking and dips. You'll lose some of that tang that sour cream offers, but it still does a great job at adding moisture to baked goods. Plus, it's relatively the same texture as sour cream, which makes it a great sub in dips and sauce.

Can I use sour cream instead of eggs in cake mix? ›

Tangy dairy products like yogurt and sour cream are a great swap when making egg-free desserts. As long as you make sure you're using full-fat varieties, these ingredients can incorporate lots of moisture to your recipes.

Can I use sour cream instead of heavy cream in a cake recipe? ›

I substitute these for each other all the time. Watch for the extra liquid in the recipe—you may need to cut down the amount of heavy cream depending on what you are making. Also, when you're moving in the other direction, expect a bit of that sour cream tang.

Does butter or oil make a cake more moist? ›

Texture:Cakes made with oil tend to be moister and have a more tender crumb. Oil coats the flour proteins better than butter, resulting in a softer texture. Cakes made with butter can have a richer flavor and a slightly firmer texture. Butter contributes to a more traditional and dense cake structure.

How do you make a cake look textured? ›

One of the best ways to add a texture onto your cake is using a texture comb. So many companies now sell them and they come in so many different designs. They enable you to smooth the buttercream on the side of your cake, whilst adding in a fun design around the edge.

What makes frosting crunchy? ›

American buttercream (ABC) is one of the easiest and most commonly made frostings, but the biggest problem that most people have with it is that it often has a 'gritty' or grainy feel to it. This is because of undissolved icing sugar (also known as powdered/confectioners sugar).
