how to make this Vanilla-on-Vanilla 9x13 Sheet Cake

For the Cake

1. Preheat to 325°F (160°C) and generously grease a 9x13 pan.
2. Cream butter, oil, and sugar for 3 minutes.
3. With the mixer on low speed, add eggs one at a time, mixing well.
4. Stir in vanilla.
5. Whisk dry ingredients separately, then alternate adding them with buttermilk.
6. Mix in Greek yogurt, then beat 45 seconds on medium-high.
7. Pour into the pan and bake for 28-30 minutes, until a tester comes out clean.
8. Cool in the pan for 10–15 minutes, then turn out onto a rack to cool completely.

For the Frosting

1. Place the butter in the bowl of a stand mixer fitted with the paddle attachment and on medium-high speed mix for 4–6 minutes until the color changes from yellow to white.
2. While mixing, sift the powdered sugar using a fine-mesh sieve or sifter into a separate bowl.
3. Turn off the mixer and add the powdered sugar in 1–2 cup increments, mixing on low speed after each addition until fully incorporated. This prevents a sugar cloud.
4. Add the heavy cream, salt, and vanilla extract.
5. Mix on medium speed for 30 seconds to incorporate.
6. Increase to medium-high speed and mix for 5–10 minutes, pausing occasionally to scrape down the bowl.

How to Store Your Vanilla-on-Vanilla Sheet Cake

This cake stores beautifully, whether you're preparing ahead for a party or saving a few slices for later. Once frosted, the whole 9x13 sheet cake can be covered and stored in the refrigerator for up to 4 days. For longer storage, you can freeze the frosted cake by wrapping it tightly in plastic wrap and then foil—just be sure it’s fully chilled before wrapping to preserve the frosting’s texture. You can also store the vanilla cake and frosting separately: wrap the cake tightly and refrigerate or freeze, and keep the frosting in an airtight container. When ready to enjoy, thaw everything overnight in the fridge. For the best flavor and texture, let the cake come to room temperature for about 1–2 hours before serving.
