I used flavor drops like these many years ago to flavor my (cheap) morning cup of coffee, among other things. I always used cream and sugar as usual, but a little Irish Cream or Amaretto or whatever makes it taste great and is cheaper than real liquor.
Flavor cream or half-n-half with some sugar/sweetener plus your choice of flavor drops to make your own "international flavors" coffee creamers.
Easy to add cherry, vanilla, or lime flavor to your Coke or bottled water.
Whip a few drops into whipped cream to top off a dessert. Almond is classy.
Surprise the kids with mint, orange, raspberry, or other flavors in their hot chocolate. Try espresso in your own.
Mix drops into cookie dough for flavor accents (try coconut or peanut butter in your chocolate chip cookies, or mint in your brownies).
Separate batter for pound cake or yellow cake into several smaller portions. Flavor one with lemon, one with orange, one with key lime, one with cherry. Add food coloring to match the flavor. Pour in layers into the pan and bake. Yum! Layers of fruity flavors, a rainbow cake. (professional food color paste from a hobby store can make super bright colors, great for kids' parties).
Stir chocolate flavor drops into a serving of peanut butter, yum!
Heck, these ARE food flavorings after all

They're so strongly flavored that you just need a bit, and it won't mess up the liquid/dry ingredient ratios in your recipes. I've noticed that chocolates that taste gross for
vaping still flavor other stuff really well.
