Vanilla Layer Cake
A classic creamed butter cake — tender, level layers built for stacking and frosting.
What's going on here
The creaming method is a mechanical leavening technique disguised as a mixing instruction: beating solid butter and sharp-edged sugar crystals together for several full minutes physically cuts thousands of tiny air pockets into the fat, and those pockets are what the batter's chemical leavening — baking powder — later expands in the oven, rather than generating lift from nothing. This is why the step genuinely needs its full time rather than being rushed; a batter creamed for one minute has far fewer air pockets to work with than one creamed for four, no matter how much baking powder gets added afterward. Room-temperature butter matters specifically because it's soft enough to trap air as it's beaten but still solid enough to hold that air's shape — melted butter can't hold a bubble at all, and butter that's too cold won't move enough to catch any. Alternating dry and wet ingredients into the creamed base, in stages, keeps the batter's air structure from collapsing under a single heavy addition of liquid.
Ingredients
Cake
- 1 cupButter, softened
- 1 3/4 cupsGranulated sugar
- 4Eggs
- 2 tspVanilla extract
- 2 3/4 cupsAll-purpose flour
- 2 1/2 tspBaking powder
- 3/4 tspSalt
- 1 1/4 cupsMilk
Frosting
- 1 cupButter, softened
- 4 cupsIcing (powdered) sugar
- 3 tbspMilk
- 1 1/2 tspVanilla extract
Instructions
Prep
- Heat the oven to 175°C (350°F) and grease and line two 9-inch cake pans.
Cake
- Cream the butter and sugar on medium-high until noticeably pale and fluffy.
Tip: Don't shortcut this — the air beaten in now is most of your leavening, and a rushed cream leaves the cake dense no matter what else you do right.
- Beat in the eggs one at a time, fully incorporating each before adding the next, then the vanilla.
- Whisk the flour, baking powder, and salt together. Add to the butter mixture in three additions, alternating with the milk in two, mixing just until combined after each.
Tip: Alternating keeps the batter from getting too wet or too stiff at any one point, which protects the air structure you built while creaming.
Bake
- Divide evenly between the pans and bake until a skewer comes out clean and the centre springs back when lightly pressed.
Cool
- Cool in the pans 10 minutes, then turn out onto a rack to cool completely before frosting.
Frost
- Beat the frosting butter until smooth, then gradually beat in the icing sugar, milk, and vanilla until fluffy. Frost between the layers and over the whole cake.

Tips for this recipe
Cake came out dense
Almost always an underdone creaming step. Give it the full time, and make sure the butter was genuinely at room temperature — too cold and it won't trap air properly.
Level the layers
If the tops domed during baking, trim them flat with a long serrated knife before stacking — a level base keeps the frosted cake from leaning.
