Helpful Tips and FAQs


Flour Substitutions

King Arthur keto Wheat Flour Substitutions

Almond Flour – Almond flour can be used at a 1 to 1 ratio, but alterations may be needed to the liquid ingredients. Using Almond Flour will also affect the final height/rise of the muffins, bread or cake. Almond Flour is finely ground almonds (skins removed) which can also change the overall flavour. Expect a nuttier flavour with a denser texture.

Coconut Flour – Coconut flour can be used as a low-carb replacement. As with almond flour, you will need to alter the liquid ingredients. Coconut flour tends to be absorbent, meaning you may need to add extra liquid to compensate. To maintain the calorie and carb content, adding extra egg or egg whites is a good option. You may lose some of the flavour, due to the coconut flavour. The end bake will also be denser.

Carbalose Flour – This is another excellent substitution for King Arthur Keto Wheat Flour. The ratio is 1-1 with the K.A. Keto Flour. One must-do of Carbalose Flour is that you need to sift it well. Sift it at least once, but twice is better. It is a dense flour and the sifting will help to add some air and lighten it up. You may need to alter the liquid ingredients. having extra egg whites on hand makes it easy to alter liquids as you go.

All-Purpose Flour – As with most non-low-carb recipes all-purpose flour is the main ingredient. You can easily switch out the King Arthur Keto Flour with All Purpose on a 1-1 ratio. Reduce the amount of baking powder to almost half. You may also need to reduce the liquids. It is a good idea to add the liquid ingredients slowly so that if your batter seems to be getting thin, you can reduce the liquid. The use of all-purpose will increase the carbs significantly.

Sweetener Substitution

I use Splenda granulated whenever possible as it does not negatively impact my blood sugar. I find that sweeteners that contain sugar alcohols cause my blood sugar to rise. If this is not a concern for you or you have a preferred sweetener, by all means, make substitutions that suit your preferences and dietary needs. Keep in mind that substituting the sweetener may change the overall nutritional information.

Adding Nuts or Chocolate Chips

Feel free to add nuts or flavourings of your choice. Chopped walnuts or pecans are especially good in Sugar Free Banana Cake. Always be mindful that adding ingredients will change the nutritional information.

Freezing and storing instructions

Store your frosted or unfrosted cake in the refrigerator for up to 5 days in an airtight container or covered in plastic wrap. For frosted

Freeze, unfrosted for up to 3 months in an airtight container.
