Vanilla sour cream cupcakes with vanilla buttercream frosting and Lego toppers

May 2, 2018

So I had a successful batch of chocolate sour cream cupcakes, but the next recipe I wanted to try was a vanilla version. I actually came up with the idea when I saw the most gorgeous paste colored fondant in the Intermarche Supermarket. So I decided, even though my youngest and oldest’s birthday is only 5 days apart, I already had the Lego molds, and they are both die hard Lego fans so to make it look a bit different I wanted to use the pastel colored fondant on a vanilla buttercream icing on top of a vanilla sour cream cupcake.

Once again I was in pursuit to find the perfect recipe, and Pinterest did not fail to deliver.

I found this delish recipe on Laurens Latest blog, and adapted the recipe.

Vanilla Sour Cream Cupcakes with Vanilla buttercream frosting



  • 3/4 cup unsalted butter, at room temperature
  • 1 1/2 cups of sugar
  • 3 eggs
  • 1 1/2 teaspoons of vanilla essence
  • 1 cup sour cream
  • 1/4 cup milk
  • 2 1/2 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt

Vanilla Buttercream frosting

  • 1/2 cup softened butter
  • 500 g powdered sugar
  • 2 tablespoons milk
  • 1 teaspoon vanilla essence


  1. Preheat oven to 180 degrees C, and line muffin tin with paper liners
  2. In a large mixer bowl cream together the butter and the sugar until light and fluffy. About 2 minutes. Add eggs in one at a time, until each is incorporated. Then add in vanilla, sour cream and milk. Scrape sides briefly.
  3. In a separate bowl whisk together all the dry ingredients.
  4. Add in dry ingredient little by little until everything is incorporated. I mixed everything in my blender, and it was super smooth
  5. Scoop batter into each cup until it is 3/4 full. Bake 25-30 minutes or until they are very lightly golden and the toothpick comes out clean when inserted. Set aside to cool completely. (very important step!)
  6. For frosting: mix butter and powdered sugar on low speed. Gradually add in vanilla and just enough milk to make frosting smooth and spreadable. Whip 3 minutes to make it light and fluffy.
  7. Double your frosting recipe if you want to pipe the frosting onto your cupcakes, otherwise if you are just using a knife, this will be enough.
  8. This recipe yielded 15 cupcakes; I made the batter twice and got exactly 30.

Lego men toppers

So you know by now that my first attempt was a failure, so my next resort was to use fondant.

  • I bought 4 packets of fondant (1x red, 1x blue, 1x green and 1x yellow)
  • I bought the Lego silicone molds on Amazon (Amazon FR; Amazon UK) and used the one with the 8 men molds.

  1. Use a drop of oil and spread it with your index finger in all of the molds, it should just look a little bit wet, just a residue left behind.
  2. Take a ball from the fondant about the size of a 1 euro coin.
  3. Press it that piece of fondant really hard into each corner of the mold, remove any excess fondant, the fondant should just cover the mold, it should not peel out and it should be flat.
  4. Place in the fridge to Harden for about 20 minutes.
  5. Pop them out and place in a bowl, repeat all 5 steps till you have the desired amount of molds.
