CLASSICS

Apple Pie

From Betty Crocker

Ingredients: 

  • Double-crust pastry
  • ⅓ to ½ cup sugar
  • ¼ cup all-purpose flour
  • ½ teaspoon ground cinnamon
  • ½ teaspoon ground nutmeg
  • ⅛ teaspoon salt
  • 8 cups thinly sliced, peeled tart apples (about 8 medium apples)
  • 2 tablespoons butter or margarine

Instructions: 

Heat oven to 425 degrees. Prepare double-crust pastry. 

Mix sugar, flour, cinnamon, nutmeg and salt in large bowl. Stir in apples. Turn into pastry-lined pie plate. Dot with butter. Trim overhanging edge of pastry ½ inch from rim of plate.

Roll other round of pastry. Fold into fourths, and cut slits so steam can escape. Unfold top pastry over filling, and trim overhanging edge 1 inch from rim of plate.

Fold and roll top edge under lower edge, pressing on rim to seal. Flute as desired. Cover edge with 3-inch strip of aluminum foil to prevent excessive browning. Remove foil during last 15 minutes of baking.

Bake 40 to 50 minutes or until crust is brown and juice begins to bubble through slits in crust. Serve warm.

Ingredients: 

  • 1 (9 inch) prepared graham cracker crust
  • 3 cups sweetened condensed milk
  • ½ cup sour cream
  • ¾ cup key lime juice
  • 1 tablespoon grated lime zest

Instructions: 

Preheat oven to 350 degrees.

In a medium bowl, combine condensed milk, sour cream, lime juice and lime rind. Mix well, and pour into graham cracker crust.

Bake in preheated oven for 5 to 8 minutes, until tiny pinhole bubbles burst on the surface of pie. Do not brown.

Chill pie thoroughly before serving. Garnish with lime slices and whipped cream.

Pumpkin Pie

From Simply Recipes

Ingredients: 

  • 2 eggs, plus the yolk of a third egg
  • ½ cup packed dark brown sugar
  • ⅓ cup white sugar
  • ½ teaspoon salt
  • 2 teaspoons of cinnamon
  • 1 teaspoon ground ginger
  • ¼ teaspoon ground nutmeg
  • ¼ teaspoon ground cloves
  • ⅛ teaspoon ground cardamon
  • ½ teaspoon of lemon zest
  • 2 cups of pumpkin pulp purée from a sugar pumpkin* or from canned pumpkin purée
  • 1 ½ cups heavy cream or 1 12 oz. can of evaporated milk
  • 1 good crust

Instructions: 

*To make pumpkin purée from scratch, cut a medium-small sugar pumpkin in half. Scrape out the insides (reserving the pumpkins seeds to toast), and discard.

Line a baking sheet with foil. Place the pumpkin halves cut side down on the lined baking sheet, and bake at 350 degrees until a fork can easily pierce them — about 1 hour to 1 ½ hours. Remove from oven, let cool, scoop out the pulp.

Preheat your oven to 425 degrees.

Beat the eggs in a large bowl. Mix in the brown sugar, white sugar, salt and spices — cinnamon, ground ginger, nutmeg, ground cloves, cardamom and lemon zest.

Mix in the pumpkin purée. Stir in the cream. Beat together until everything is well mixed.

Pour the filling into an uncooked pie shell. Bake at 425 degrees for 15 minutes. Then after 15 minutes, lower the temperature to 350 degrees.

Bake for 45 to 55 minutes more or until a knife inserted in the center comes out clean. 

Cool the pumpkin pie on a wire rack for 2 hours. Note that the pumpkin pie will come out of the oven puffed up from the leavening of the eggs but will deflate as it cools.

Strawberry Coconut Oatmeal Crunch Pie

From Diethood

Ingredients:

  • 2 cups cereal flakes with strawberries (e.g., Kellogg’s Special K Red Berries)
  • 1 cup quick oats
  • ⅓ cup all-purpose flour
  • 1 cup sweetened, shredded coconut
  • ¾ cup honey (maple syrup can also be used)
  • ¼ cup water
  • 1 tablespoon corn starch
  • ½ cup strawberries, mashed or pureed
  • 3 cups sliced strawberries, divided

Instructions:

Preheat oven to 375 degrees. Grease a 9-inch pie plate with baking spray and set aside.

Place cereal in a Ziploc bag, close the bag and crush the cereal with a rolling pin. In a mixing bowl, combine 1 cup of crushed cereal, oats, flour, coconut and honey. Stir until completely blended.

Press mixture into previously prepared pie plate. You can use a buttered spatula to do this, or you can also spray some cooking spray on your hands so that the mixture doesn’t stick.

Bake for 8 to 10 minutes, or until golden brown. Let cool completely.

Prepare the strawberry sauce by combining water and corn starch in a microwave-safe bowl. Stir until well blended.

Mix in mashed strawberries and microwave for 30 to 40 seconds or until sauce is thickened. Spread sauce on top of cooled pie.

Arrange sliced strawberries, and refrigerate for 20 to 30 minutes or until chilled. Garnish with 1 cup of crushed strawberry cereal flakes.

Candy Bar Pie

From Crazy for Crust

Ingredients:

  • 1 pie crust
  • 1 cup brown sugar
  • ¼ cup unsalted butter, softened
  • 1 egg
  • 2 teaspoons vanilla extract
  • 1 teaspoon baking powder
  • ¼ teaspoon salt
  • 1 cup flour
  • 1 cup candy or candy bars (e.g., miniature Reese’s Peanut Butter Cups, Rolos or M&Ms)
  • Extra candy for the top of the pie

Instructions:

Preheat oven to 350 degrees. Place pie crust in a 9-inch pie plate, crimping as desired. Press the sides of the crust so they are firmly attached to the edges of the pie plate.

Cream brown sugar and butter in the bowl of an electric mixer fitted with a paddle attachment (or you can use a hand mixer). Add eggs and vanilla, and beat until combined. Add baking powder, salt and flour and mix.

If you are using a stand mixer, add your candy bars to the bowl and mix on medium-high to chop of the candy. If you’re using a hand mixer, coarsely chop the candy, then mix it into the dough.

Press into prepared pan (since the dough will be sticky, spray your hands with cooking spray to avoid problems). Press some remaining candy on the top for decoration. Press the sides of the crust that are showing with the tines of a fork a few times.

Bake for about 24 to 30 minutes, until the crust is browned and the top of the pie is golden. It may still be a little jiggly in the center.

Cool completely before cutting. Serve by itself, or with whipped cream or ice cream.
