MAKE CUPCAKES: Preheat oven to 350°F. Line 12 muffin cups with paper liners.
SIFT together flour, salt and baking powder in a medium bowl; set aside. In a large bowl, beat together butter, sugar, lemon zest and lime zest with a mixer at medium speed until light and fluffy, 3 to 4 minutes, scraping down sides of bowl occasionally. Beat in eggs, one at a time. Gradually add flour mixture to butter mixture alternately with soda, beginning and ending with flour mixture, beating just until combined after each addition. Divide batter evenly among prepared muffin cups.
BAKE for 18 to 23 minutes or until a wooden pick inserted in center comes out clean. Cool for 10 minutes in pan, then remove from pan and cool completely on a wire rack.
MAKE FROSTING: Beat together confectioners’ sugar, butter, lime zest and salt in a large bowl at medium speed, just until combined.
ADD lemon juice gradually and beat until frosting is light, fluffy and has a smooth, pipeable consistency. Transfer to a piping bag fitted with a medium open star pastry tip (Wilton 1M) and pipe frosting onto cupcakes. Garnish with lemon and lime slices, if desired.
Is it okay if the 7-up is flat?
Hi JT, We would not recommend using flat 7Up. The carbonation in the soda works with the leavening agents to give the cupcakes a nice rise. Happy baking!
Please send me carrot cake recipe
Hi Evelyn, Here is a link to our delicious Carrot Cake recipe. Thanks and happy baking!
My Grandmother used Swans Down flour for baking when I was growing up. Used for her pound-cakes, the flour is awesome. My questions are:
*Does Swans Down have a hard cover or three ring cookbook and if so, where can I purchase?
*I noticed a recipe tin used in your advertisements on Facebook. I’d love to have one as well as any other vintage items. Where can I purchase one?
Please Advise and Thanks,
Hi Sandy, We LOVE hearing from long time Swans Down users. At this time we do not have a hard cover recipe book. Though, it’s a great idea! We do have this new recipe booklet that you can download https://swansdown.com/2020/12/04/cake-recipes-worth-passing-down/ .
The recipe tin used in our Facebook post was a premium item we offered years ago. Unfortunately we don’t have any available to purchase, but it is on our list as a comeback item!
Do you have a recipe for a 7up cake?
Hi Lana, You can use our 7Up Cupcake recipe to bake a cake. Simply replace 12 cupcakes tins with one 8″ or 9″ pan. Happy baking!
