Introduction: Doctor WHOokies
Step 1: Ingredients
¾ cup sugar
2 large eggs
1 tsp. vanilla extract (follow this Instructable to make your own!)
2 cups AP flour, plus more if needed
1 tsp. baking powder
1 tsp. salt
1 3D printed TARDIS cookie cutter
2 baking sheets, lined with parchment paper
1 bottle blue gel paste food coloring
1 cup confectioner’s sugar
Step 2: Cream 'em
Start by creaming your butter and sugar until it becomes a light and fluffy mixture.
Step 3: Make Them TARDIS Blue
Add a small amount of food coloring (start with less than you think you’ll need, coloring strength can vary and while you can always add-to you can’t take-out), mix thoroughly adding more food coloring if necessary to achieve desired color.
Step 4: Bring on the Eggs
Mix in eggs & vanilla extract (preferably Uncle Chris’ Fancy Vanillin Extract).
Step 5: Bring on the Dry Team
Combine flour, salt and baking soda in a large bowl and mix to combine.
Step 6: Let Them Sleep With the Snowmen
Split dough into 2 flat discs and chill in the fridge for at least an hour.
Step 7: Roll Out
Pre-heat oven to 350.
Lightly flour work surface and rolling pin. Keep your rolling pin floured as this dough can be a bit sticky. Roll 1 disc of dough to 1/4″ thick.
Step 8: Give Them the Cut
Use the cookie cutter to cut out the cookies, then lightly press the cookie stamp into each cookie.
Step 9: Send Them Around the Sun
Throw these in your preheated oven (you set it to 350 right?) and bake for 8-12 minutes.
Step 10: Ice to Meet You
While the cookies are cooling you can go ahead and make your icing. Mix the hot water and confectioners sugar in a bowl. You can add more sugar if the icing is too thin, or more water if it's too thick.
Then pour your icing into a piping bag, or do like I did and pour it into a zip-top bag and cut off the corner.
Step 11: Finishing
After the cookies are completely cool it's time to ice them. On my first batch I added the windows and signage (as close as I could) to match the TARDIS. The second batch got a slightly lazier drizzle (though they were equally delicious).
Now pack a few of these up and go on an adventure (watch out for Daleks)!
