Lone Goose Bakery Vanilla Extract

Two ingredients that I never bake without are vanilla and salt. I’m pretty sure most bakers would tell you the same thing. Leaving one of these out can really make or break a baked good. Using high-quality vanilla can take your treats to the next level. You can truly taste the difference between using cheap vanilla and high-quality vanilla. My current favorite is this Madagascar Bourbon Pure Vanilla Extract from Lone Goose Bakery. It really takes the flavor of these Funfetti Cookie Sandwiches up a notch!

This vanilla is going to be a staple for all of my holiday baking. It’s the (not so) secret ingredient that will have people asking for your recipe! You can use the code Ellie10 for 10% off of your order. Lone Goose Bakery also has a whole host of high-quality baking ingredients that are quickly becoming staples in my pantry!

What is American buttercream?

American Buttercream is a mixture of butter and powdered sugar. It is much simpler to make than Italian or Swiss Buttercream, but it is also sweeter. American buttercream is known for being more firm than other buttercreams.

Ingredients for the funfetti cookies:

  • Unsalted butter. I always make sure to use unsalted butter when baking because there is no “standard” for the amount of salt they can add to butter. So if you add salt to a recipe and then use salted butter you could end up with a very salty end product.
  • Granulated sugar. This is normal sugar
  • Eggs. It will be easier to incorporate the eggs into the batter if they are room temperature.
  • Vanilla extract. Vanilla is a must in baked goods just like salt. Real vanilla adds a better flavor than imitation vanilla. I highly recommend Lone Goose Bakery’s vanilla extract
  • All-purpose flour. Measuring the flour correctly is very important. I suggest weighing your flour out (I use this scale). If you want to use a measuring cup, make sure you spoon the flour into the cup and level it off with a knife. Don’t use the cup to scoop directly from the flour.
  • Baking soda. This will help the funetti cookies rise.
  • Baking powder. This also helps the cookies rise.
  • Salt. Salt is a must in baked goods. It will help to balance out the sweetness and improve the overall flavor.
  • Sprinkles. I prefer jimmies sprinkles for these cookies. I used these from Wilton.

Ingredients for American buttercream:

  • Unsalted Butter. It needs to be very soft.
  • Salt.
  • Vanilla Extract.
  • Powdered Sugar. Also known as confectioners sugar.
