Preheat oven to 350 degrees F.
Line a rectangular baking sheet with parchment paper and set aside.
In a small bowl, sift together flour, baking powder, and salt.
In a larger bowl, whisk together eggs and sugar. Add vanilla and canola oil and whisk until completely combined.
In thirds, slowly add dry ingredients into a large bowl of wet ingredients, alternating with the milk.
Once the batter is formed, add blue gel food coloring and mix until completely tinted.
Pour batter onto a lined baking sheet and even it out with a spatula.
Bake for about 15-20 minutes.
Allow to cool and once cooled, cut out 12 circles using your cookie cutter.
