Preheat your oven to 325 degrees F. This initial step sets the stage for baking, ensuring your pie cooks evenly and gets that golden-brown crust. Make sure your oven is fully preheated before placing your pie inside, as this affects the overall texture and baking time.
Grease a pie plate. This prevents sticking and makes for an easier release once the pie is done. Use a bit of butter or cooking spray to coat the bottom and sides of the plate generously.
In a medium bowl, using an electric mixer, beat the eggs until foamy, about three minutes. This aerates the eggs, incorporating air that helps the pie rise slightly and gives it a fluffy texture.
Add the flour, brown sugar, granulated sugar, and vanilla to the foamy eggs. Beat until all ingredients are thoroughly combined. You should see a smooth, slightly thick batter forming.
Next, add the butter to the mixture. Continue beating until it’s thoroughly combined. The batter will be thick, but don’t worry if it looks a bit lumpy; that’s perfectly fine!
Now, gently stir in the semi-sweet chocolate chips. Use a spatula or wooden spoon to fold them into the batter, ensuring even distribution. This ensures every bite contains that delicious chocolate.
Press your pie crust into the prepared pie plate, making sure to cover the bottom and sides evenly. This creates the perfect vessel for your gooey filling.
Drizzle half of the sweetened condensed milk over the bottom of the crust. This forms a luscious layer that will melt beautifully into the filling.
Spoon in half the filling over the milk, spreading it evenly. This gives the pie a beautiful layer of chocolate goodness.
Drizzle the remaining sweetened condensed milk over this layer of filling to add an extra creamy texture.
Spoon in the rest of the filling, ensuring it’s evenly distributed. This helps create that iconic gooey center.
Transfer the pie to the oven and bake for 55 to 60 minutes, or until a tester inserted into the center comes out clean. Keep an eye on it towards the end, as baking times can vary based on your oven.
Allow the pie to cool for at least 20 minutes before slicing. This cooling time allows the filling to settle, making serving easier. You can serve it warm or at room temperature—both options are delightful!
