For the Pans
For the cakes: In large bowl, whisk together flour, salt, baking powder, and baking soda.
In bowl of stand mixer (or large bowl if using handheld mixer), combine 6 tablespoons softened butter and remaining ⅔ cup sugar. Lock bowl into place and attach paddle to stand mixer, if using.
Start mixer on medium-high speed and beat until mixture is pale and fluffy, 3 to 4 minutes. Stop mixer.
Use rubber spatula to scrape down sides of bowl. Add eggs and vanilla. Start mixer on medium speed and beat until combined, about 30 seconds. Stop mixer.
Carefully add half of flour mixture. Start mixer on low speed and mix until combined, about 30 seconds. With mixer running, pour in buttermilk and mix until combined, about 30 seconds. Stop mixer.
Add remaining flour mixture. Start mixer on low speed and mix until well combined, about 30 seconds. Stop mixer. Remove bowl from stand mixer, if using.
Use rubber spatula to scrape down sides of bowl and stir in any remaining dry flour. Use large spoon to divide batter evenly among muffin tin cups (use rubber spatula to scrape batter from spoon if needed) and smooth tops.
Place muffin tin in oven. Bake until cakes are light golden brown and toothpick inserted in center of 1 cake comes out clean, about 15 minutes.
Use oven mitts to remove muffin tin from oven (ask an adult for help). Place muffin tin on cooling rack and let cool for 10 minutes.
Use oven mitts to invert muffin tin over cooling rack (ask an adult for help—muffin tin will be hot) and gently tap muffin tin cups to help cakes release. Let cakes cool completely on rack, bottom side up, about 30 minutes.
For the glaze: In second small bowl, whisk together confectioners’ sugar, zest, and 2 tablespoons juice. Whisk in additional juice as needed until glaze is thick but pourable.
The British define a tea cake as any light, yeast-raised sweet bun with dried fruit. The Scots say a tea cake is a chocolate-covered, marshmallow-filled cookie. American southerners will tell you that a tea cake is more like a biscuit or a cookie. At America’s Test Kitchen Kids, we think a tea cake is any baked good you serve with your tea. This extra-light mini cake with citrus glaze is the perfect addition to any tea party.
