I make creme brulee with splenda and it's always a hit with my Atkins kids.

Sugar Free Cre Brulee

1 quart heavy cream
2 teaspoons pure sugarless vanilla extract
8 large egg yolks
1/2 cup Splenda
superfine sugar to glaze

1. In small saucepan, scald cream with vanilla over medium heat. Remove from heat. Place eight 6-ounce ramekins in a roasting pan; set aside.
2. Preheat oven to 300 degrees F, with a rack in the center. In small bowl, whisk egg yolks just until blended. Slowly whisk in 1/2 c. Splenda. Slowly beat in hot cream into the yolks, whisking all the time. (You may strain it at this point, but I didn't). Pour custard into the ramekins.
3. Place the roasting pan on the center rack of the oven. Pour in enough hot tap water to reach about halfway up the sides of the ramekins. Bake until the custards are just set, about 30 minutes (the timing can vary based on the depth of the ramekins). Remove the custards from their water bath and place on wire rack until cooled.
4. Refrigerate until very cold, at least 3 hours.
5. When ready to serve, put superfine sugar on top of custard and cover it well. Torch it to desired color. Serves 8.

I also make the Brown Sugar Chocolate Chip cookies from Sol and use the Splenda/Brown Sugar mixture.

Brown Sugar Chocolate Chip Cookies - Sol

2½ cups AP flour
1 teaspoon baking soda
1 teaspoon salt
1 cup (2 sticks) unsalted butter, room temperature
2 cups light brown sugar, packed
2 large eggs
1 tablespoon vanilla extract
2 cups semisweet chocolate chips
½ cup chopped walnuts, optional
Whisk together the flour, baking soda and salt. In a mixer, cream the butter and sugar until light. Add the eggs, one at a time, beating well after each addition. Add vanilla. On low speed, add the flour mixture, and mix until barely blended. Add chocolate chips and nuts. Drop by tablespoons onto sheet pan and bake in a 350°F oven, for 12-15 minutes

I made strawberry jam with splenda and pectin for sugar free jams and wasn't impressed at all.

I haven't tried using splenda in canning, but I usually refer to the splenda website when looking for recipes that work. It seems that you just can't substitute splenda for sugar in all recipes.

I also like this site because there are reviews of recipes, and recipe contest submissions.

Here is a link that might be useful: Splenda Recipes

Warning - long post! I make the following recipes with Splenda on a regular basis. If a recipe calls for 1 cup, I'll use a Splenda Quick Pack which has 24g fewer carbs than 1 cup of the spoon for spoon Splenda. I'm diabetic so I have to watch my carbs. Enjoy!

The Fantabulous Whole Wheat Carrot Cake (original recipe from Recipezaar)
16 servings in 9"x13" pan or 24 mini-muffins

1 1/2 teaspoons baking soda
1 teaspoon salt
2 teaspoons cinnamon
1 cup Splenda or 1 Splenda Quick Pack
1/2 cup chopped walnuts
4 eggs
1 cup canola oil (or substitute with some apple sauce)
2 cups grated carrots
1 cup unsweetened crushed canned pineapple, drained

Combine dry ingredients. Beat oil and eggs until frothy; stir in carrots and pineapple. Mix wet ingredients with dry until just mixed - do not over mix. Put into greased baking pans of your choice.

Bake at 350° - 15 min for mini-muffins; 25-30 min for 8"x8" pan; 30-40 min for 9"x13" pan.

Cool in pan several minutes, then remove from pans and cool completely on wire rack.

Sweet Potato Mini Muffins (I think this originally was lindac's recipe)
24 mini-muffins

1 1/2 cups white whole wheat flour, sifted
2 teaspoons baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
1/2 teaspoon nutmeg
1 teaspoon cinnamon
1 cup Splenda or 1 Splenda Quick Pack
1 cup chopped pecans
2 large eggs, lightly beaten
1/4 cup buttermilk
1/4 cup melted butter
1 cup cooked and mashed/pureed sweet potatoes (I use more)

Preheat oven to 350° convection bake.

Mix together dry ingredients, including nuts.

Mix butter, sweet potato, eggs and milk in a large bowl.

Stir in the dry ingredients until just moistened and spoon into greased muffin tin. Do not over mix as too much gluten will develop and make the muffins tough.

Bake at 350° for about 15 minutes. Let cool in pan a few minutes, then remove and let cool on a rack.

Chocolate Cake Brownies (Nechama Cohen)
12 servings

Note: I use all white whole wheat flour and add a little more oil and coffee. I also double the recipe and use a 9"x13" pan.

2 eggs plus 1 egg white (I use 2 jumbo eggs)
1/3 cup walnut oil
3/4 cup Splenda granular
1/4 cup all-purpose flour
1/4 cup whole wheat flour
1 tsp baking powder
1/2 tsp baking soda
dash of salt
1/4 cup chopped nuts
1/4 cup almond flour or finely ground almonds
1/2 cup strong coffee
1/2 cup unsweetened dark cocoa
1 tsp vanilla extract

Preheat oven to 350 F. Line an 8" square pan with parchment paper.

With an electric mixer on a high setting, beat the eggs, slowly adding the oil and Splenda until the mixture gets thick.

Sift the flours with the baking powder, baking soda and salt. Add the chopped nuts and nut flour.

Mix the coffee, cocoa and vanilla extract.

Mixing by hand with a wooden spoon or spatula, add the flour and coffee mixtures to the eggs mixture, alternating between the two. Pour into the pan and bake for 25-30 minutes.

When the top is just firm to the touch, remove from the oven. Do not use the toothpick test for doneness. This cake should come out very moist. Place on a grate to cool. Cover and refrigerate. When cold, using a serrated knife, cut into 12 equal squares. Store in an airtight container or freeze.

Curd Cheese and Apple Soufflé (nami-nami food blog)

2 cups curd cheese or ricotta (I use 1% small curd cottage cheese)
4 large eggs
5 Tbs dry cream of wheat, uncooked
1/2 cup plus a little more sour cream or plain yogurt (I use reduced fat sour cream)
6-1/2 Tbs sugar (I use 10 packets of Splenda)
a pinch of salt
4-1/2 cups or 2-1/2 large apples (I used three 4" Braeburns, peeled)
lemon juice

Topping:
cinnamon
sliced almonds
butter

Wash the apples, peel (optional), core and slice thinly. Sprinkle with lemon juice to avoid turning dark.

In a large bowl, mix cheese until smooth. Add eggs, one by one, mixing thoroughly between each addition. If you prefer a fluffier soufflé, whisk the egg whites separately and fold in gently at the end.

Add cream of wheat, sour cream/yogurt, sugar/Splenda and salt; stir until combined. Fold in sliced apples.
Pour the mixture into a large buttered oven dish or a non-stick spring form pan with parchment paper on the bottom. Sprinkle top with cinnamon and sliced almonds, and dot with butter.

Bake at 350° for about 45 minutes (mine took 70 min) or until the soufflé has risen and turned a light golden color.

Serve either hot or cold. A warm curd soufflé is good served with cold milk; a cold one goes well with crème anglais. (FYI - I eat it with no topping.)
