Frequently Asked Questions

Why did my One Batter Moist Marble Cake turn out dry? It's as rough as sandpaper!

A dry marble cake can be a real bummer! It usually boils down to a couple of culprits: overbaking or too much flour. Make sure you're using the correct measurements (scales are your friend!) and that you're not baking it for longer than necessary - a toothpick inserted into the center should come out clean. Also, room temperature ingredients help create a more emufied and therefore moist cake.

Help! My marble effect is more of a muddy mess. How do I get those lovely swirls in my One Batter Moist Marble Cake?

Ah, the dreaded muddy swirl! The key is to be gentle and resist the urge to over-swirl. Alternate dollops of the vanilla and chocolate batters in the pan, and then use a toothpick or skewer to lightly swirl them together. Think of it like creating a watercolour painting – a few strategic strokes are all you need. Less is definitely more here!

Can I make this One Batter Moist Marble Cake recipe ahead of time, like the day before a party?

Absolutely! In fact, making it a day ahead can actually enhance the flavours. Once the cake is completely cool, wrap it tightly in plastic wrap or store it in an airtight container at room temperature. It'll stay moist and delicious. You can even give it a light dusting of icing sugar just before serving for that "freshly baked" look.

Is there a way to adapt this recipe if I'm avoiding dairy or gluten?

Good news, yes! For a dairy-free version, substitute the buttermilk with a plant-based milk like almond or soy, and ensure any butter or oil you use is also dairy-free. For a gluten-free version, use a good quality gluten-free all-purpose flour blend (one that contains xanthan gum). Keep an eye on the baking time, as gluten-free cakes can sometimes bake a little faster. Remember to have fun with it and adapt as you wish!

What if I don’t have buttermilk on hand? Is there a substitute I can use for this One Batter Moist Marble Cake?

No buttermilk, no problem! You can easily make a substitute by adding 1 tablespoon of white vinegar or lemon juice to a measuring cup, then filling the rest of the cup with milk until you reach 1 cup total. Let it sit for 5 minutes, and you've got a perfectly acceptable buttermilk substitute. It works like a charm!
