Instructions

Keto Tootsie Rolls

In a large mixing bowl, sift together ¼ cup Unsweetened Cocoa Powder, ¼ cup Unflavored Whey Protein Powder, 2 tablespoons Powdered Whole Milk, ½ cup Powdered Erythritol, and ⅛ teaspoon Kosher Salt. Stir to combine, then set aside.
¼ cup Unsweetened Cocoa Powder, ¼ cup Unflavored Whey Protein Powder, 2 tablespoons Powdered Whole Milk, ½ cup Powdered Erythritol, ⅛ teaspoon Kosher Salt
Melt 2 tablespoons Unsalted Butter.
2 tablespoons Unsalted Butter
In a small microwave safe bowl, heat 60 grams Sukrin Fiber Syrup for about 30 seconds or until bubbles form.
60 grams Sukrin Fiber Syrup
Stir in the melted butter and ½ teaspoon Vanilla Extract.
½ teaspoon Vanilla Extract
Pour the liquid into the dry ingredients and mix. It will be crumbly at first. Then use your hands to continue mixing and kneading it until a dough forms.
This quantity makes 36 pieces, so I suggest dividing it into 4 balls, then those into 3 smaller balls, then each of those into 3 small pieces. (See Notes for alternative method.)
You can wrap them individually in wax paper pieces if you’d like. However, since we’re going to be using them in larger quantities, I suggest just rolling several (5 or 6) of them at a time in a piece of wax paper. Then seal them in a zip top bag or other airtight container to store in the fridge until you’re ready to assemble the Keto Kitty Litter Cake.

Keto Vanilla Pudding

Separate 12 Eggs. Discard the egg whites or save them for another use. Beat the 12 Egg Yolks in a large mixing bowl with 3/4 cup Powdered Erythritol until pale. Set aside.
12 Egg Yolks, 3/4 cup Powdered Erythritol
Pour 4 cups Heavy Cream into a large saucepan with 1/4 cup Vanilla Extract. (As an alternative, you could split open 4 Vanilla Beans, scrape the insides out into the Heavy Cream and then steep the insides and the emptied vanilla bean pods in the Heavy Cream for about 5 minutes.)
4 cups Heavy Cream, 1/4 cup Vanilla Extract
Remove the Vanilla-infused Cream from the heat and allow it to cool for a few minutes. You should be able to put your finger in it. Checking it with a thermometer, I let it get down to about 90”F.
Pour about 1 cup of the warm liquid into the egg yolks, beating continuously until fully incorporated and the eggs have come up to temperature.
Pour the egg and cream mixture back into the rest of the heated cream, continuing to stir.
Place the combined mixture back onto low to medium heat and continue cooking while stirring until it begins to thicken and will coat the back of a spoon. (Note: If you have an induction burner, this would be a great time to use it.) This will take quite a while, particularly since you are working with a large quantity of liquid.
Once it has begun to thicken, remove the custard from the heat, pour it through a strainer into a clean mixing bowl, and continue stirring until it cools. Due to the quantity of liquid, this will take another 5 - 10 minutes.
Push a sheet of plastic wrap down onto the surface of the pudding and up the edges of the bowl.
Place in the refrigerator for at least 2 hours to cool completely. (If you are working with a smaller quantity, it could be chilled in as little as 1 hour.)

Keto Vanilla Birthday Cake

Butter a 9x13-inch cake pan and coat it with almond flour and preheat the oven to 350”F.
4 tablespoons Unsalted Butter, ½ cup Almond Flour
Sift and mix the dry ingredients (2 ½ cups Almond Flour, ½ cup Unflavored Whey Protein Powder, 1 tablespoon Baking Powder, and ¼ teaspoon Kosher Salt). (See link in Notes for original Keto Vanilla Birthday Cake recipe instructions.)
2 ½ cups Almond Flour, ½ cup Unflavored Whey Protein Powder, 1 tablespoon Baking Powder, ¼ teaspoon Kosher Salt
Beat ½ cup Unsalted Butter (softened) and ¾ cup Granulated Erythritol for about 2 minutes or until fluffy.
½ cup Unsalted Butter, ¾ cup Granulated Erythritol
Add the 3 Eggs, one at a time, beating well after each addition. Then add in 1 tablespoon Vanilla Extract and beat again.
3 Eggs, 1 tablespoon Vanilla Extract
Mix in half of the dry ingredient mixture, then ½ cup Unsweetened Vanilla Almond Milk, and finally the remaining half of the dry ingredients.
½ cup Unsweetened Vanilla Almond Milk
Pour the batter into your prepared 9x13-inch pan and bake at 350”F for 25 - 30 minutes. Start checking it at the 20 minute mark, as your oven may vary. It should be golden brown around the edges.
Allow to cool in the pan for 30 minutes before transferring to a cooling rack to finish cooling completely. Set aside until the other cake is also cooled.

Pour into one of the prepared 9x13-inch cake pans and bake at 350”F for 25 - 35 minutes. Start checking it at the 25 minute mark, as your oven may vary.
Allow to cool in the pan for 30 minutes before transferring to a cooling rack to finish cooling completely. Set aside until the other cake is also cooled.

Assembling the Keto Kitty Litter Cake

Unwrap 18 ounces Catalina Crunch Vanilla Cream Cookies (about 3 packages) and divide out ¼ of them to set aside. Crush ¾ of the cookies either in a food processor or in a zip top bag with the flat side of a meat tenderizer. Set aside.
18 ounces Catalina Crunch Vanilla Cream Cookies
Then repeat that step with the remaining ¼ of the cookies. If you are using a food processor, add 3 drops of green food coloring and pulse a couple more times to turn the cookie crumbs green. If you are using a bag, add the food coloring to the smaller bag. I found that I needed closer to 6 drops of food coloring in this case because my ability to evenly distribute it is nowhere near as good as a food processor. Set aside.
3 - 6 drops Green Food Coloring
Break the white and chocolate cakes into small chunks.
Add about ⅓ of each cake and ⅓ of the non-green crushed cookies to the new and sanitized litter box. Use large spoons or your hands to combine. Add some pudding and mix again. You want the pudding to moisten everything and make it clump, but not to make it soggy. Repeat with the remaining cake, cookies, and pudding.
Once everything is well mixed, push several of the keto tootsie rolls into the cake (so that they are buried. Then strategically place some more on top of the cake and / or sticking out of the surface. If you want to go all in, quickly microwave a couple to make them more pliable and then position them up the side of the litter box and / or over the edge, pressing down lightly to make them stick to the surface.
Sprinkle the green tinted crushed cookies on top.
Serve with a new and sanitized litter scoop if desired.
Store leftovers in an airtight container in the fridge for up to a week.

Notes

Making Keto Vanilla Pudding on an Induction Burner
- While certainly not required, we’ve found that the heat control and consistency that you get from an induction burner is great for tasks like making custards or melting chocolate without burning it. You can of course just use the regular stove, but if you happen to have one and maybe forget about it sometimes, this is a great time to use it.
- We have and like this one: Duxtop Portable Induction Cooktop, Countertop Burner Induction Hot Plate with LCD Sensor Touch 1800 Watts, Silver 9600LS/BT-200DZ
Sifting Dry Ingredients
- Keto Tootsie Rolls
  - I definitely recommend sifting the dry ingredients on this one to eliminate clumps. You’re trying to mimic a commercially made candy, so a smoother texture is your friend.
- Keto Vanilla Cake and Keto Chocolate Cake
  - I still recommend sifting to provide a better texture for the cakes, but realistically, you are going to be breaking them apart and then mixing them together with pudding. A less than smooth texture isn’t going to matter that much. So if you need somewhere to cut time, cutting out the sifting could be an option.
Method for Rolling Keto Tootsie Rolls
- Rather than dividing your dough down into 36 tiny balls and then rolling them into cylinders, you can roll the dough into a larger ball, flatten it, then cut it into a long strips the width of a Tootsie Roll. Then cut those strips into individual pieces and roll to make them cylindrical.
- Either way will work. Dividing the dough into tiny balls worked best with my brain, but you do you.
