Cheesecake is a sweet dessert consisting of one or more layers. The main, and thickest layer, consists of a mixture of soft, fresh cheese (typically cream cheese or ricotta), eggs, and sugar.It may be baked or unbaked (usually refrigerated).

Cheesecake is usually sweetened with sugar and may be flavored in many different ways. It may be flavored by adding vanilla, spices, lemon, chocolate, pumpkin, or other flavors to the cheese layer. Additional flavors and visual appeal may be added by topping the finished pie with fruit, whipped cream, nuts, cookies, fruit sauce, chocolate syrup, or other toppings.

Here,in this Instructables I am going to teach you how to make a simple no-bake and no-crust classic cheesecake from scratch!(It is 100% FAILPROOF) Enjoy!

Step 1: Ingredients

four 8-ounce blocks (904g) full-fat cream cheese, softened to room temperature
1 cup (200g) granulated sugar
1 cup (240g) full-fat sour cream, at room temperature
1 teaspoon pure vanilla extract
2 teaspoons fresh lemon juice (optional, but recommended)
3 large eggs, at room temperature

Step 2: Make the Filling

Using a handheld or stand mixer fitted with a paddle attachment, beat the cream cheese and granulated sugar together on medium-high speed in a large bowl until the mixture is smooth and creamy, about 2 minutes. Add the sour cream, vanilla extract, and lemon juice then beat until fully combined. On medium speed, add the eggs one at a time, beating after each addition until just blended. After the final egg is incorporated into the batter, stop mixing. To help prevent the cheesecake from deflating and cracking as it cools, avoid over-mixing the batter as best you can.

Step 3: Prepare the Simple Water Bath

Boil a pot of water. You need 1 inch of water in your roasting pan for the water bath, so make sure you boil enough. I use an entire kettle of hot water. As the water is heating up, wrap the aluminum foil around the springform pan. Pour the cheesecake batter on top of the crust. Use a rubber spatula or spoon to smooth it into an even layer. Place the pan inside of a large roasting pan. Carefully pour the hot water inside of the pan and place in the oven. (Or you can place the roasting pan in the oven first, then pour the hot water in. Whichever is easier for you.)

Step 4: Cut the Cheesecake

Use a knife to loosen the chilled cheesecake from the rim of the springform pan, then remove the rim. Using a clean sharp knife, cut into slices for serving. For neat slices, wipe the knife clean and dip into warm water between each slice.

Step 5: Decorate, Serve and Enjoy It!

Serve cheesecake with desired toppings.For me, I have decorated the cake with slices of fresh fruits (Kiwi and strawberry).Cover and store leftover cheesecake in the refrigerator for up to 5 days
