Name: Birthday Cake Pie
Prep time: 20 min
Total time: 5 h 30 min
Yield: 8 - 10 serving(s)
Ingredients: 1 1/2 c. (180 g.) all-purpose flour, plus more for surface; 2 tsp. granulated sugar; 1/2 tsp. kosher salt; 1/2 c. (1 stick) unsalted butter, thinly sliced; 3 tbsp. (to 4) ice water; 6 tbsp. rainbow sprinkles; 1 large egg, beaten with 1 tbsp. water; 2 c. heavy cream; 1 c. vanilla cake mix; 1 (3.4-oz.) package instant vanilla pudding mix; 1 1/2 c. cold milk

Step 1In a large bowl, whisk flour, sugar, and salt. Add butter and, using your fingertips, mix into dry ingredients until crumbly. Gradually add 3 to 4 tablespoons ice water, 1 tablespoon at a time, until a pliable dough forms. Fold half of sprinkles into dough until just combined.

Step 2On a lightly floured surface, turn out dough and form into a disc. Cover with plastic wrap and refrigerate at least 1 hour or up to overnight.

Step 3Preheat oven to 425°. On a lightly floured surface, roll out dough to a 1/4"-thick round. Carefully roll dough around rolling pin, then unfurl into a 9" pie dish. Crimp edges, then brush with beaten egg. Line dough with parchment or foil, leaving some overhang. Fill with pie weights or dried beans.

Step 4Bake crust 12 minutes. Remove parchment and weights and continue to bake until golden brown, about 5 minutes more. Let cool.
