HOW TO MAKE MARBLE CUPCAKES, STEP BY STEP:
- Line 2 cupcake tins with liners and preheat the oven to 350 degrees F.
- In a liquid measuring cup or a medium mixing bowl whisk together the buttermilk, melted and cooled butter, oil, egg whites, and vanilla extract until well combined.
- In a separate medium mixing bowl whisk together the flour, sugar, baking powder, baking soda, and salt.
- Pour the wet ingredients into the dry ingredients bowl and mix until just combined.
- Pour half the batter into a separate bowl. To one bowl add the extra flour and vanilla extract and mix until just combined.
- To the second bowl add the cocoa powder and mix until just combined.
- Fill each liner with half chocolate batter and half vanilla batter, alternating with a spoonful of each at a time. Fill each liner 2/3 full.
- Use a toothpick to swirl the batters together.
- Bake for 17-19 minutes or until a toothpick inserted comes out with a few moist crumbs.
- Let the cupcakes cool in the tin for 5 minutes before removing to a wire cooling rack to finish cooling all the way.
- To make the frosting, in the bowl of a stand mixer fitted with a paddle attachment add the butter. Whip for 2-3 minutes until the butter is light and fluffy.
- Add the powdered sugar, 4 tablespoons of heavy cream, and vanilla extract and mix on low at first until combined and then on high until light and fluffy, at least 5 minutes. If the frosting is too thick, add an additional tablespoon of heavy cream and mix again.
- Remove half of the frosting to a bowl.
- To the remaining frosting in the stand mixer bowl add the cocoa powder and additional heavy cream. Mix until fully combined.
- In a piping bag fitted with an open star tip add the vanilla frosting on one side and the chocolate frosting on the other side.
- Pipe completely cooled cupcakes with swirls.
WHY DO ALL MY INGREDIENTS NEED TO BE AT ROOM TEMPERATURE?
This helps create a smooth batter and also aids in baking evenly. When things are room temperature the blend together and emulsify.
When they emulsify it creates a light and fluffy texture that you really desire in baking.
DO I HAVE TO MAKE TWO DIFFERENT FROSTINGS?
No, this is something we like to do to make sure one flavor does not overpower the other.
You can choose to make vanilla or chocolate frosting, just remember to double the additional ingredients needed for each of the recipes if not making both.
DO I HAVE TO USE BUTTERMILK?
I highly recommend using buttermilk in this recipe, it helps with the flavor and the texture.
If you do not have buttermilk you can add 1 Tablespoon white vinegar or lemon juice to one cup of regular milk.
Stir and let sit for about 5-10 minutes, stir again and use.
WHY DO I USE JUST EGG WHITES?
We are making white cupcakes, so we are using egg whites. If you were to use the whole egg you would have more of a yellow cupcake.
So make sure when you make these cupcakes, you are using the whites only. If you use the whole egg they won’t turn out.
HOW TO STORE:
These can be stored in an airtight container at room temperature for 2 days or in the refrigerator for up to 5 days.
They can also be frozen, unfrosted cupcakes can be placed in a freezer container where they will keep for up to 2 months, frosted cupcakes can be frozen for up to 1 month.
To defrost remove to the countertop or refrigerator until thawed. Frost if you froze them unfrosted.
TIPS AND TRICKS:
- If you want a little extra chocolate flavor add some mini chocolate chips to the batter.
- Make sure your ingredients are at room temperature, see above on why.
- These can be frozen, see above on how to do that.
- For best results, sift your cocoa powder as it usually has clumps that are hard to mix in.
- To save on a dirtied dish you can simply wipe out the bowl used for wet ingredients with a paper towel and use it to make the chocolate batter in.
- Easily double this recipe to serve for more people.
- You can choose to make just a vanilla or chocolate frosting instead of doing the swirl.
- If your buttermilk is cold, it will make your melted butter harden when mixed in and result in flat cupcakes.
When it comes to that perfect dessert, you cannot go wrong when you make these Marble Cupcakes.
