Trader Joes Fall Favorites
This Pumpkin Chocolate Chunk Oatmeal Cookie Mix is bright on display amongst the rest of the fall items promoted. Every year, Trader Joes decks out their entire store and product list with fall flavors! Pumpkin: cold brew coffee, bagels, bread + muffin mix, ice cream, hummus, oatmeal, yogurt, waffles, samosas and SO MUCH MORE. And this is just pumpkin, we haven’t even touched the other flavors like cinnamon, apple, maple, or caramel. The cookie mix stood out as something we could have fun with for our Pumpkin month at TKC!
BUTTERCREAM TIPS
Everyone loves ice cream cake, ice cream sandwiches, and ice cream cookie sandwiches. They are so good, but either melt too fast or leaves you with a soggy cookie. How do we avoid this? It’s simple: replace the ice cream with a smooth buttercream. These sandwiches will last all day long, won’t melt, and is much easier to add different toppings to. Have fun with ideas like drizzling chocolate over the sandwiches or creating a well in the middle of the icing, and filling it with pumpkin butter (or caramel, nuts, etc). We followed package instructions + added white chocolate chips to the final batter.
I’ve come to enjoy making buttercream because there are so many flavors to explore. Whether it’s lemon based, orange based, coconut based, or chocolate based–buttercream can always be fun and exciting! Don’t let the task of making buttercream take you out of your baking zone. Although it can be very tricky, and quite complex to make, I’ve settled on some key tips to making the perfect buttercream:
- Beat the butter first until it becomes fluffy, then add powdered sugar in small chunks.
- using softened butter is best
- Use milk or heavy cream
- heavy cream will help you get that thick, creamy texture, while milk will give you a fluffier texture.
- add your milk or cream slowly. you can always add more, but you can never take the milk out.
- Add vanilla extract (or any other flavored extract)
- this brings extra flavors and added sweetness to your buttercream
- Cover the bowl with a towel while mixing
- there are many times I’ve had powdered sugar flying everywhere when adding it to the mixer because it wasn’t covered
- The spatula test!
- this is a quick way to confirm that your frosting is the perfect consistency
- press a spatula into your frosting and pull it up.
- the frosting should be a stiff peak with a slight curl on the end
- if it’s too stiff add more milk, if it’s too thin, add more powdered sugar (1/3 cup at a time)
And that’s it! There’s nothing more satisfying than putting buttercream into a piping bag and letting your creative mind flow when you’re decorating.
