Equipment

Step by Step Instructions

  • Preheat Oven: Set to 350°F (175°C) and line 2 baking sheets with parchment paper.
  • Dry Ingredients: In a medium bowl, whisk flour, baking powder, baking soda, and salt together.
  • Wet Ingredients: Using a whisk, mix sugars, melted butter, yogurt, and oil in a separate large bowl.
  • Combine: Add egg and vanilla to wet mixture. Then, fold in the flour mixture until well incorporated.
  • Shape Cookies: Scoop dough using a medium size cookie scoop. Roll each cookie dough ball in extra sugar and place on the prepared baking sheet.
  • Bake and Cool: Bake for 11-13 minutes. Let cookies cool completely on the baking sheet.
  • Frosting Prep: In a bowl of a stand mixer, beat butter with a paddle attachment until fluffy. Gradually mix in powdered sugar.

Substitutions and Variations

  • Gluten-Free: Easily make these cookie sandwiches gluten-free by using a gluten-free flour blend in place of regular flour.

  • Vanilla Beans: Add the seeds from a vanilla bean or a tablespoon of vanilla bean paste for extra flavor.
  • Alternative Fillings: Instead of sprinkles, consider adding chocolate chips, cream cheese filling, chocolate ganache, or marshmallow creme.

How to Store

  • Room Temperature: Store leftover cookie sandwiches in an airtight container. They’ll stay fresh for up to 5 days.
  • Freezing Baked Cookies: Place cookies on a cookie sheet in a single layer. Freeze for half an hour, then wrap in plastic wrap and store in a freezer bag. They’ll last up to 3 months.
  • Freezing Unbaked Cookie Dough: Scoop dough onto a cookie sheet, freeze for a half hour, then transfer to a freezer bag. Bake straight from the freezer, adding a couple of extra minutes to the baking time.
  • Freezing Frosted Cookies: Freeze frosted cookies on a cookie sheet for an hour, then wrap each in plastic wrap. Thaw at room temperature for a few hours before serving.

expert Tips

  • Weigh Out Ingredients: For the perfect cookie, accuracy is key. Weighing out your ingredients ensures consistent results every time.
  • Don’t Overbake Cookies: Keep an eye on your cookies to ensure they don’t overbake. They should be just golden around the edges for that tender cookie texture.
  • Cool Cookies Completely: Before adding frosting, let the cookies cool completely. Frosting warm cookies can cause the frosting to melt and slide off.
  • Room Temperature Ingredients: Ingredients like eggs and yogurt should be at room temperature. This ensures they blend more evenly into the dough.
  • Uniform Size: Use a cookie scoop for evenly sized cookies. This helps them bake uniformly and makes your sandwich cookies look professional.

Frequently Asked Questions

What’s the best way to ensure my cookie sandwiches are evenly baked?

The best way to achieve evenly baked cookies is to ensure they’re the same size. Use a cookie scoop or weigh out the cookie dough for consistency, and always bake on the middle rack of your oven.

How do I get perfectly round cookies?

To get perfectly round cookies, gently shape the dough with your hands after scooping. You can also use a round cookie cutter to neaten the edges after baking.

Should I scrape the sides of the bowl while mixing?

Yes, it’s important to scrape the sides of the bowl occasionally while mixing. This ensures all ingredients are well-incorporated for a uniform dough.

Is it necessary to cool cookies on a wire rack?

Cooling cookies on a wire rack is crucial. It allows air to circulate around the cookies, preventing them from becoming soggy and helping them set properly.

Can I make the cookie dough ahead of time?

Absolutely! You can prepare the dough in advance and refrigerate it. Just let it sit at room temperature for a few minutes before scooping and baking.
