With a toothpick or end of a thin wooden utensil, dab a bit of vanilla on each pecan swirl pastry - in the areas of the nose, eyes, and antlers. This will be the "glue."
On top of the glue, add one red M&M to the nose area.
Above the nose, add two candy eyes.
At the top, add two pretzels for the antlers.
Repeat for all pastries.
Notes
Note: our package of pecan swirls included 6 pecan swirls so we used two packages in order to get 12 servings. You may need to adjust your ingredients based around how many pastries come in your package/desired number.
