Preheat the oven to 350°F (180°C).
In the bowl of a stand mixer or with an electric hand mixer, cream together the butter and granulated sugar until light in color and fluffy in texture. This will take about 2 minutes.
3/4 cup (167g) salted butter, 3/4 cup (173g) granulated sugar
Scrape the sides and add in the egg and vanilla.
1 1/2 tsp vanilla, 1 egg
Once combined, add the flour, baking powder and canola oil. Mix until a soft dough comes together.
2 1/2 cups (380g) all-purpose flour, 1 1/2 tsp baking powder, 1 tbsp canola oil
Roll the dough out on a floured surface until thin (between 1/8” and 1/4”).
Use a small rectangle cookie cutter (mine was 3”x2”) to cut the dough.
Arrange half of the rectangle cookies onto a parchment or silicone lined cookie sheet.
Carefully spoon 1/2 tsp of the strawberry glaze into the center of each rectangle.
1/4 cup strawberry glaze
Top gently with a remaining rectangle of cookie dough. Gently press the edges down and then use a fork to crimp the edges and poke in a few venting holes.
Bake at 350°F (180°C) for 10-12 minutes or until the edges begin to turn golden brown.
Remove from the oven and let the cookies cool completely.
Once cool, make the glaze by whisking together the warm water, corn syrup and clear vanilla in a medium sized bowl.
2 Tbsp very warm water, plus more as needed, 1 tsp light corn syrup, 1/8 tsp clear vanilla flavoring
Slowly add the powdered sugar to the water mixture, whisking constantly until all of the powdered sugar has been incorporated.
1 cup (107g) powdered sugar
Add warm water 1/4 tsp at a time until you reach a slow dripping consistency. You can add some white food coloring to make your icing a bright white, if desired.

Ice each cookie with approximately 1 1/2 tsp of icing. Spread gently and carefully. Add sprinkles to the icing and then allow the icing to set up before serving. Enjoy!
