So pretty they can be at a wedding, (they have), so photogenic they can appear in a magazine (they have), and so delicious you’ll want to make again – gluten-free lemon cupcakes with blackberry buttercream! This is truly one of the best gluten-free lemon desserts there is!

Gluten-free Lemon Cupcakes with Fresh Blackberry Buttercream

These beautiful and delicious gluten-free lemon cupcakes with fresh blackberry buttercream might look familiar to those of you that have been following me for a while. Last year, they appeared in an issue of the magazine Gluten Free Living. I promised that I would put them on the blog and then completely forgot! I was looking through photos for upcoming posts and saw these and thought I’d better get this recipe up!

These have quickly become one of my favorite cupcakes. I’ve made them several times now, sometimes with this fresh blackberry buttercream, sometimes with fresh raspberry buttercream (same recipe, just using raspberries).

I’ve mentioned before that we grow raspberries and blackberries in our backyard. They grow really well here with our hot Idaho summers. Frankly, they are pretty much the only thing I like about living in Idaho in July and August! I’m not lying when I say that about the only time I head outside during those two hot months is when I’m going out to pick our fresh berries.

In the spring, before our berries are producing, I buy fresh California berries at our Costco. They are always delicious too! This buttercream frosting is so good, you’ll be looking for more things to put it on! I could eat spoonfuls of it, not that I have (ahem) before!

Gluten-free Lemon Cupcakes with Blackberry Buttercream Recipe

If you have to avoid dairy, try my gluten-free lemon coconut cake recipe.

Last summer, my boys’ first ever babysitter got married. Her new husband has found that he’s gluten intolerant, so she asked if I would make cupcakes for her wedding reception to serve alongside of their wedding cake. While I knew these cupcakes rock, I was nervous about making them for a wedding. It all turned out well. The cupcakes came out delicious, survived the curvy hour drive up in the mountains and sitting outside on a hot summer day.

Here’s a picture of these gluten-free lemon cupcakes with the raspberry frosting at the wedding reception where they were displayed on a cool tree trunk stand:

Gluten-free Lemon Cupcakes with Raspberry Buttercream for a wedding! So cute displayed on this tree trunk cake stand!

As with most of my recipes, I’ve tested these cupcakes with gfJules flour and also Gluten Free Mama’s Almond Blend Flour and recommend you use one of them. Feel free to use your favorite gluten-free flour blend and let me know in the comments how it works for you in this recipe! Hope you can make these soon!

I absolutely love gluten-free lemon desserts! Here are some more to try, like my gluten-free lemonies – they’re similar to a brownie in texture and are so good! Or how about gluten-free lemon cookies? I so want to make this gluten-free lemon tart from my friend Megan. This gluten-free lemon poke cake looks easy and yummy and I bet would be fun for my boys to help make.

Lemon Buttermilk Cupcakes with Fresh Blackberry Buttercream {Gluten-free}

Gluten-free Lemon Cupcakes with Fresh Blackberry Buttercream

Gluten-free lemon cupcakes with blackberry buttercream! This is truly one of the best gluten-free lemon desserts there is! You can use raspberries instead of blackberries too.

Prep Time 40 minutes
Cook Time 25 minutes
Additional Time 20 minutes
Total Time 1 hour 25 minutes

Ingredients

Cupcakes:

  • 3 cups all-purpose gluten-free flour *(see note below)
  • 1 ½ teaspoon xanthan gum
  • 1 Tablespoon baking powder
  • ½ teaspoon salt
  • 1 cup (2 sticks) unsalted butter, room temp.
  • 2 cups sugar
  • 4 large eggs
  • 2 Tablespoons grated lemon zest
  • 1 teaspoon pure vanilla extract
  • 3 Tablespoons fresh lemon juice
  • 1 cup buttermilk

Fresh Berry Buttercream:

  • 1 cup (2 sticks) butter, softened
  • 6 cups powdered sugar (also called confectioners’ sugar)
  • 7 T. strained blackberry puree (made from about 1 ½ cup of fresh blackberries)
  • 1 tsp. pure vanilla extract

Instructions

Cupcakes:

  1. Preheat oven to 325°. Line standard muffin tins with paper liners.
  2. In a small bowl, whisk together flour, xanthan gum, baking powder & salt. Set aside.
  3. In the large bowl of your electric mixer, cream butter & sugar until pale & fluffy.
  4. Add eggs, one at a time, beating until each is incorporated, scraping down the sides as needed.
  5. Beat in the zest & vanilla.
  6. Add flour mixture in three batches, alternating with two additions of buttermilk & lemon juice, beating until just combined after each addition.
  7. Divide batter among lined cups, filling each ¾ full. I use a large cookie scoop/ice cream scoop to ensure equal sized cupcakes.
  8. Bake at 325° for about 25 minutes, or until a toothpick inserted in center of cupcake comes out clean and edges have just started to brown. Transfer tins to wire racks to cool. After about 10 minutes, remove the cupcakes from tins and allow to cool on wire rack.
  9. Buttercream:
  10. Using a blender or food processor, thoroughly puree the blackberries. Strain the pureed blackberries through cheesecloth or a fine strainer/sieve to remove the seeds. (Discard seeds) You will use 7 tablespoons of this puree.
  11. In a mixing bowl, beat butter on medium speed until fluffy, about 2 minutes.
  12. Slowly add 1 cup powdered sugar and beat until smooth.
  13. Add blackberry puree and pure vanilla extract and beat.
  14. Gradually add in the remaining powdered sugar, beating on low speed until combined. Then beat on medium high until light and fluffy, about 3 minutes.

Notes

*I have tested this recipe with gfJules Flour and also Gluten-free Mama's Almond blends. If you use a gluten-free flour blend that contains xanthan gum in it already, then omit the additional xanthan gum listed in this recipe.
*Use raspberries instead for fresh raspberry buttercream.

Could I use this recipe as a cake?? What would I need to change?

I haven't tried this as a cake yet. But feel free to try! Just divide evenly among your round pans or into a sheet pan and watch your cooking time. I'm not sure how long this would take to bake, and would depend on your pan size too. Please let me know if you try it!

I made these cupcakes yesterday, using Bob's Red Mill 1-to-1 gluten free flour mix, and they were deliciously light and fluffy. Everyone enjoyed them, though only one person was totally gluten free. I did find that the amount of frosting was much more than I needed. I would likely cut the recipe in half for next time.

I just made these today, they remind me of pound cake or sponge cake, very good but my question is should they have this texture?
