Make-Ahead Options! The dry ingredients and wet ingredients can be prepared earlier in the day or the night before, and kept in separate covered bowls (dry ingredients on the counter, wet ingredients in the fridge) until you are ready to combine everything together and bake. For best results, however, we recommend that you don’t prepare the caramel swirl until the last minute, as it tends to thicken considerably upon standing. These freeze beautifully, so you may want to make a double batch! To freeze, wrap individually and store in freezer bags. They will thaw in about 45 minutes or, after removing foil liner, can be gently defrosted at 50% power in the microwave in about 50-60 seconds.
