Step-by-Step Instructions: Making Your Chocolate Mayonnaise Cake

Okay, baking this *Chocolate Mayonnaise Cake* is seriously simple. Don’t let the “fancy” ingredients fool you – it’s all about following a few easy steps. I always say, read the whole recipe first, so you know what’s coming. Then, let’s get baking!

Get Your Oven Ready! First things first: Preheat your oven to 350°F (175°C). Super important! While the oven heats up, grab a 9×13 inch baking pan. Grease it up really well with cooking spray, then dust it with flour. Tap out any extra flour. This helps prevent the cake from sticking – because nobody wants a mangled cake!
Dry Ingredients First. Grab a big bowl! In that bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Whisk ’em good to make everything is combined. This part is important because it makes sure you don’t have clumps later.
Wet Ingredients Next. Now, in another bowl, beat together the sugar, eggs, mayonnaise, milk, and vanilla extract. Whisk until it’s all smooth and creamy. It should look like a lovely, delicious mess, honestly!
Combine, Gently! Slowly add the dry ingredients to the wet ingredients. Mix until just combined. Be careful not to overmix! Overmixing develops gluten, which can make the cake tough. A few streaks of flour? Totally fine!
The Hot Water Trick! This is how you get that crazy moist cake. Very slowly, and carefully (it splatters!) stir in the boiling water. The batter will be thin, don’t freak out!
Bake & Cool! Pour that beautiful batter into your prepared pan. Bake for about 30-35 minutes. To check if it’s done, stick a toothpick in the center. If it comes out clean, it’s ready! Let the cake cool completely in the pan before you even think about frosting it (I know, it’s hard to wait!).

Tips for Chocolate Mayonnaise Cake Success

Okay, so you want to nail this *Chocolate Mayonnaise Cake*? Absolutely! Here are a few things I’ve learned from making (and eating!) tons of these cakes over the years. Trust me, it’ll help make yours perfect:

Oven Temp Matters: Make sure your oven is actually at 350°F (175°C), not just what the dial says! Oven thermometers are your friend.
Don’t Overmix: This is SO important! Mix until just combined. Overmixing equals tough cake. Nobody wants that!
Toothpick Test is Key: Stick a toothpick in the center. If it comes out clean, or with a few moist crumbs, you’re golden! If it’s still got wet batter… back in the oven! Gently, carefully.

Follow these tips, and you’ll be on your way to a seriously amazing *Chocolate Mayonnaise Cake*! Happy baking!

Ingredient Notes and Substitutions for Chocolate Mayonnaise Cake
