Filling

• In a medium sized bowl, whisk together the cornstarch and sugar, then add the eggs and whisk until smooth. Set aside.¼ cup cornstarch,½ cup granulated sugar,2 large eggs
• Prepare a large bowl with a fine mesh strainer – you will need this immediately after your pastry cream comes off the heat.
• Pour the milk and salt into a medium saucepan over medium-high heat and bring it to just under a boil, stirring occasionally so you don’t burn the milk solids on the bottom of the pan.2 cups whole milk,¼ teaspoon kosher salt
• Once the milk is simmering well, add ⅓ of the milk to the egg mixture and whisk constantly. Pour the egg mixture into the saucepan with the rest of the milk and return to medium high heat.
• Whisking vigorously and constantly, the mixture will begin to thicken and you will see the small milk bubbles start to disappear. Once this has happened, the mixture will quickly thicken and boil. Allow it to boil for about 30 seconds, then remove it from the heat and pass it through the sieve into the bowl. Use the whisk/rubber spatula/wooden spoon to mix the custard around to get it through the sieve.
• Allow the pastry cream to cool to 140℉, then whisk in one tablespoon of butter at a time. Don’t add a new piece until the other has been fully incorporated. Once all butter has been added, add the vanilla and mix to combine. Cover the bowl with plastic wrap and press the wrap directly on the pastry cream so it doesn’t form a skin. Put the pastry cream in the fridge to chill for at least 3 hours.¼ cup unsalted butter,1 teaspoon vanilla paste or extract

Peanut Butter Crumbles

• Add the flour to a microwave safe bowl and microwave in 30 second increments stirring in between, until the mixture reaches 160℉ on a digital thermometer.½ cup all-purpose flour
• Note: heat treating the flour must be done in order to be safe to eat.
• Pass the flour through a fine mesh sieve into a large bowl to remove any hard chunks. Add the powdered sugar and mix with a fork to combine.1 ½ cups powdered sugar
• Add the peanut butter, and mash the ingredients together until it comes together and doughy crumbles form. This takes a bit of elbow grease.1 cup peanut butter

Whipped Cream

• Add the heavy cream, powdered sugar, and vanilla to the bowl of a stand mixer fitted with the whisk attachment (or use a handheld mixer) and beat on high speed until stiff peaks form.1 cup heavy whipping cream,¼ cup powdered sugar,2 teaspoons vanilla paste or extract
