These Cinnamon Oatmeal Custard Bars with Rum Raisin Sauce are the epitome of “cookies reimagined”, and show off one of McCormick’s eight Flavor Forecast trends for this year.

I’m always so excited to work with McCormick and see the annual report (this year marks the 15th anniversary), because it gives a good indication of what we’ll be seeing in restaurants and on store shelves in the future — delicious taste sensations!

8 Flavor Trends to Watch

Identified by a global team of McCormick chefs and flavor experts, these trends offer a taste of 2015 and beyond:

  1. Global Blends On the Move – Japanese 7 Spice (Shichimi Togarashi) offers a new kind of spicy heat, while Shawarma Spice Blend lends warm, spiced flavor to grilled meats and more.
  2. Middle Eastern Mezze – These distinctive dips and spreads, packed with zesty herbs and seasonings, offer an approachable and delicious introduction to a vibrant global cuisine.
  3. Sour + Salt – Combining coarse salt with surprising sours like pickled ginger, sour cherry, dried mango and lemon zest results in a lively finishing flavor that lends brightness and texture to dishes.
  4. Smoked Spices – Smoking spices and herbs deepens their flavor and aroma, adding richness to meals and drinks.
  5. Umami Veggies – For a fresh way to savor the tempting “fifth taste,” look no further than naturally umami-rich veggies like mushrooms, tomatoes, sweet potatoes and nori.
  6. Liquid Revolution – Fresh purees and juices blend with bold spices and herbs to intensify sauces, pasta, dressings and more – providing a fun, delicious way to enjoy an extra serving of fruits and veggies.
  7. Flavor Worth the Wait – Lift the lid to discover the rich flavors from recipes around the world that meld aromatic spices and comforting ingredients into mouthwatering slow-cooked meals.
  8. Cookies Reimagined – Classic spiced cookie flavors take new form in decadent, imaginative desserts that redefine “milk and cookies.”

You’d better believe I’ll be experimenting with each of these McCormick 2015 flavor trends and recipes, but I had to start by making these Cinnamon Oatmeal Custard Bars with Rum Raisin Sauce.

How can I resist an oatmeal cookie crust topped with a tangy buttermilk custard, sweet rum raisin sauce and a crunchy oat crumble?

I. can’t.

The secret spices (well, they’re not that secret…you can buy them anywhere) are McCormick Roasted Saigon Cinnamon, McCormick Pure Vanilla extract and McCormick Imitation Rum extract.

McCormick knows their stuff, y’all.

The proof is in the cookie.

  • Meanwhile, mix granulated sugar and melted butter in large bowl with wire whisk until well blended. Add eggs, mix well. Stir in 1/2 cup of the remaining buttermilk, remaining 1/2 teaspoon cinnamon and vanilla. Pour over sauce in crust.
