And lemon totally reminds me of springtime, but without the allergies, sinus infections, pollen everywhere, and random days of hot weather that spring usually brings.

All that I can do without.

And one of the first things I baked when I first started baking was lemon bars. Well… my version of lemon bars. It was simply lemon cake mix, baked into a bar recipe, and studded with white chocolate chips. They were so simple but so delicious, and to this day they’re still one of my family’s favorite recipes.

They’re sweet, tart, and bursting with lemon flavor from that irresistible lemon bar filling, and they have just the right hint of crunch and sparkle from the yellow sugar sprinkled on top.

Ingredients

  • 1 box lemon cake mix plus ingredients on back of box
  • 1 small box lemon pudding mix just the dry mix - I used sugar free, but you can use any kind
  • 1 can Duncan Hines Lemon Pie Filling
  • 3/4 cup unsalted butter softened to room temperature
  • 1 tsp vanilla extract
  • About 3-4 cups powdered sugar
  • Yellow sanding sugar for garnish

Instructions

  • Preheat oven to 350* degrees F. Line 2 muffin tins with about 18 paper liners. Set aside. Meanwhile, prepare the cake mix according to package directions on back of box. Stir in the lemon dry pudding mix to incorporate.
  • Fill each muffin tin about 3/4 of the way full with the batter. Bake for approx. 15-18 minutes or until a toothpick inserted near the center comes out clean or with moist crumbs. Cool the cupcakes completely.
  • Using a small paring knife or a cupcake corer, core the cupcakes and discard centers, being careful not to puncture through the cupcake's bottom. You only want to core about halfway through the cupcake. Fill with some of the lemon pie filling.
  • Now, to make your frosting: In the bowl of a stand mixer, cream together butter, vanilla extract, and 1/3 cup of the lemon pie filling until fluffy, about 2 minutes. Add in the powdered sugar, one cup at a time, until frosting is light and fluffy. You may not need all of the powdered sugar. If frosting becomes too thick, add in a little more lemon pie filling.
  • Spoon the frosting into a piping bag attached with a large open-star tip. Begin piping the frosting onto the cupcakes, taking care to cover the lemon filling in the center. Sprinkle immediately with the yellow sanding sugar. Serve immediately, or store cupcakes airtight at room temperature for up to a day, or airtight in the fridge for up to 3 days.

    • Sandra, feel free to search a site like AllRecipes.com for a scratch-made lemon cake. Then proceed as normal! 🙂

    • Hi Laura, if there’s pudding in the cake mix you can omit the pudding from the recipe. However, I’ve added pudding to cake mix containing pudding and it works just the same 🙂

  19. Pure perfection. Can’t wait to have a reason to make them again. A huge hit. And fun to make!

  20. These look yummy!! But would they hold up at room temperature for about 4 hours? I have an open house I would like to use them at!

  21. I have tried this recipe twice. The cupcakes come out of the oven looking like souffles and very shortly afterwards they have shrunk down and in to mini cupcake size. Why? I ask? Did any one else have this problem? and, what can you do to keep them from shrinking?

    • Hi Donna! I am sorry this recipe is giving you troubles. Some suggestions: when too much air is incorporated into the cake batter (as is the case with accidentally over-mixing the batter), this will cause the cupcakes to deflate and shrink once removed from the oven. Also, make sure you fill your cupcake tins 3/4 full, which still gives the cupcakes space to expand and rise. Hope this helps!

    Very delicious! I made a homemade lemon curd for the filling because I couldn’t find canned lemon pie filling. That wasn’t too hard to do and it all turned out amazing! The yellow sanding sugar really sets these off. Family and friends loved them!

    Theses are delicious. I think I put too much filling in the cupcake, so you might want to watch your portion. The frosting is delicious. I made these for a birthday party and they were a hit!

    Just took the cupcakes out of the oven. Am going to refrigerate them after frosting. Taking them to a picnic tomorrow, so will refrigerate them until then. My concern is the sugaring will it dissolve if refrigerated
    Thank you!
