How long is ganache good for?
I like to keep this whipped ganache in the fridge, where in an airtight container it will stay fresh for up to a month! Simply allow to come to room temperature before using again.

Yes, it can sit out at room temperature for up to 2 days, covered. After that it should be chilled to store.

Chewy oatmeal cookies make the perfect sandwich cookie
Instructions for the sandwich cookies:
For the Maple Ganache:
- Warm the heavy whipping cream in a saucepan over medium heat, add in the maple syrup and vanilla extract. Whisk to combine, heat for 6-8 minutes, stirring often.
- Add the chopped white chocolate into a large mixing bowl or into the bowl of a stand mixer. Pour the warm maple cream mixture over the white chocolate and stir gently as the chocolate starts the melt. The cream should completely melt the chocolate, stir until you have a smooth mixture. It will still be very runny. Cover and allow to set in the fridge overnight or for at least 3 hours.
- After the ganache has set and cooled completely, use a stand or hand mixer fitted with a whisk attachment and whip for 6-8 minutes until stiff. After a few minutes of whipping check the consistency of the ganache, you want a stiff frosting that will hold its shape.
- Once the whipped ganache is done it will be thick and much lighter in color. Transfer to a piping bag fitted with a tip of choice. You can also spread the frosting between the cookies with a knife. If you plan to make the frosting ahead of time keep chilled until an hour before you plan to use it, allow to come to room temperature before piping.
For the Oatmeal Cookies:
- In a medium mixing bowl, combine the flour, baking powder, baking soda, cinnamon and salt, set aside. Line baking sheets with parchment paper or silpat liners.
- In the bowl of a stand mixer fitted with a paddle attachment or a hand mixer, combine the butter and sugars. Cream for 3-4 minutes until light and fluffy. Add in the eggs, one at a time, and the vanilla. Scrape down sides and slowly add in the dry ingredients. Mix until fully combined. Add in the oats and gently mix in on low, until incorporated.
- Cover and allow the dough to chill for 20-30 minutes, overnight if needed. Preheat oven to 350 degrees F.
- Using a portion scoop, scoop even sized scoops of cookie dough – roughly 1 1/2 tablespoons per cookie. Arrange evenly on a lined cookie sheet, leaving 2 inches between each cookie. Bake for 9-11 minutes until golden brown, cookies will still be soft in the middle. Allow to cool for a few minutes on the cookie sheet before transferring to a cooling rack. Repeat with the remaining dough, allow cookies to cool completely before frosting.
- Pipe or spread the prepared maple ganache frosting between two cooled oatmeal cookies, sandwich and repeat. These are best enjoy the same day, but will keep for 2-3 days in the fridge if stored in an airtight container.
Notes:
*You must use heavy whipping cream in the ganache in order for it to whip.
*Any leftover ganache will keep in the fridge for up to a week.
*Use a round cookie cutter to scoot warm, freshly baked cookies into perfect circles!
