Preheat oven to 350F (177C) and prepare two deep 8" round cake pans² by lining the bottoms with parchment paper and lightly greasing the sides. Set aside.
In the bowl of a stand mixer (or in a large bowl using an electric mixer) cream together the butter, canola oil and sugar until creamy and well-combined.
Add eggs, one at a time, beating until thoroughly combined after each addition.
Stir in vanilla extract.
In a separate, medium-sized bowl, whisk together flour, baking powder, and salt.
Using a spatula and gently hand-mixing, alternate adding flour mixture and buttermilk to the butter mixture, starting and ending with flour mixture and mixing until just combined after each addition. The batter should be thoroughly combined, but there may be some small lumps in the batter and avoid over-mixing (and do not use your electric mixer or stand mixer for this step).
Evenly divide batter into your prepared cake pans, and bake on 350F (175C) for 30-35 minutes. When the cake is done, the surface should spring back to the touch and a toothpick inserted in the center should come out mostly clean with few moist crumbs (no wet batter).
Allow cakes to cool in their cake pans for 10-15 minutes before inverting onto cooling rack to cool completely before frosting.
Frost cake using my chocolate frosting (or see notes for other favorite frosting options) and decorate with sprinkles (if desired).
You may use any neutral cooking oil instead of vegetable or canola oil. I generally don't recommend olive oil, which is heavier and has a distinct flavor that could affect the end taste result of your cake.

Bake times for all pans listed above have been provided by readers who have tested this recipe in different sized pans. Please always use the toothpick test to check for doneness and note that your precise bake time may vary depending on your particular baking pan and your oven. I have not tested this recipe in any other baking pans, other than cupcake tins (details for baking cupcakes listed below).
This recipe will make approximately 24 vanilla cupcakes. Fill cupcake liners no more than ¾ of the way full. Bake on 350F for 17-18 minutes or until a toothpick inserted in the center comes out with a few moist crumbs or clean.
The chocolate frosting I linked to in the ingredients is my favorite pairing with this cake, but here are some other great options:
