Hey there! Before you scroll, there’s lot’s of important stuff in the post!…including the FAQ section, which may answer any questions you might have about this recipe. Enjoy!
Now let’s talk about just some of the ingredients that are in the cake and buttercream recipes. (The list of ALL ingredients are in the recipe card below.)
All-purpose flour: This recipe calls for plain all-purpose flour…no worrying about having to get cake flour or any special ingredients. Just make sure when you measure flour, that you spoon it into the measuring cup so that it doesn’t get packed into it. (See more about this in the FAQ section below.)
Unsalted butter: This will be used for both the cake and the buttercream. You’ll want to make sure to let it come to room temperature (don’t microwave it though) before using it.
Sour Cream: This is the star in this vanilla cake. Sour cream in cakes really helps give them a soft texture, makes them super moist and it enhances the taste as well.
Vanilla Extract: Make sure not to skip this as it’s what will give the vanilla cake a nice vanilla flavor. If you have access to vanilla bean paste, that’s even better.
How to make this cake:
Let’s talk about how to make this vanilla mini cake. (The detailed instructions are also in the recipe card below.)
First, you need to preheat the oven to 350 degrees F. Then grease and flour (or spray) two, 6 inch round cake pans that are 2 inches deep.
Make sure that you also set the butter out to come to room temperature on its own. You can cut it into chunks and it will warm up faster.
Next, in a large mixing bowl, add the dry ingredients (flour, sugar, baking powder, and salt) and whisk together.
In another bowl, add the liquid ingredients (oil, eggs, sour cream, milk and vanilla) and whisk together until everything is smooth.
Now, the mixing method for this cake is called the reverse creaming method. You can get a really soft cake by using this and it’s used when there is a high ratio of sugar to flour. I actually find this method easier than the old creaming method.
So, to do this, you’ll add the chunks of butter to the dry mixture and mix with an electric mixer on medium speed while you add the butter in.
Mix until the mixture resembles a coarse, sand-like texture. You basically want the butter to coat the dry mixture.
Now add half the liquid to the dry mixture and mix on medium until well combined.
Next, add the second half of the liquid mixture and mix on medium until well combined.
Make sure to scrape down the sides of the bowl and then mix again just until all the ingredients are well incorporated. Be very careful not to over-mix at this point.
Pour the batter into the prepared pans and make sure to smooth it level. Bake at 350 degrees F for approximately 40-45 minutes.
While the cake is baking, make the buttercream.
For the buttercream, cream the butter with an electric mixer on medium speed until it’s super smooth.
Add the confectioner’s, salt, vanilla and 2 tablespoons of milk and mix on low until combined, then on medium to medium-high until well mixed. Make sure to scrape down the sides of the bowl then mix again.
Check the consistency and if it’s too thick add another tablespoon of milk and mix well. Cover well and set aside while the cake cools.
Once the cake layers have baked, cool on a wire rack, in the pans, for about 10-15 minutes.
Now turn the cakes out onto the racks and allow them to cool completely before covering them with buttercream.
The tops of these cake layers will flatten out a bit as they cool, but you can also level the tops with a knife to get them flat in order to decorate.
Add the buttercream to the cooled layered cake.
Pipe decorative borders and add sprinkles if desired.
Tips & FAQs:
Generally, you could probably classify any cake that’s smaller than an 8-inch cake, like a mini cake. This mini cake recipe is for a 6 inch, two-layer cake.
This cake will serve about 8 people. If you cut larger sizes, it will serve less and if you cut thin slices, you will get more servings.
Make sure not to pack the flour down into the measuring cup. Spoon the flour into the cup and level it off, but don’t scoop the flour. Packing too much flour into the measuring cup will end up adding too much flour to the cake batter and will make the cake dry and tough.
Unsalted is always best because you can estimate the proper amount of salt that will be added plus salted butter has a different water content than unsalted.
However, if you’re unable to get unsalted butter, you can use salted butter in the cake and the buttercream, but omit any additional salt that each recipe calls for.
It’s really important to make sure that the butter is at room temperature for both the cake and the buttercream.
Set it out an hour or two before you plan to make the cake. You don’t want to microwave the butter as that will heat it either too much or unevenly and can cause problems with the cake mixing method.
Sour cream is really best here as it makes for a softer texture and really helps give the cake moistness and a good flavor. If you can’t get it, you can substitute it with this plain yogurt.
Make sure and use full-fat yogurt though and not low fat. The fat helps make the cake moist.
Be very careful not to mix the batter for a long time. Scratch cakes should not be mixed for minutes at a time, or they will become dense. Stop mixing once the ingredients are well incorporated.
This cake is done baking when a toothpick inserted into the center of each layer comes out with a few moist crumbs on it or clean, but no raw batter.
This cake can be made ahead of time and frozen if desired. Let the baked cake layers cool completely, then wrap in plastic wrap and foil and place in the freezer for up to a month or two.
To thaw, place the wrapped cake layers on the counter at room temperature and let thaw completely, then remove the wrapping. Once defrosted add buttercream.
This cake can be stored, covered well, at room temperature for 2-3 days. After that, to prolong freshness, it can be stored in the refrigerator, well covered, for another 2-3 days.

This cake is best served at room temperature. If cold, pop a slice in the microwave for about 10-15 seconds.
