Helpful Tips
Substitutuions
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 flour will increase the carbs significantly.
Sweetener Substitutions
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, feel free to make substitutions that suit your preferences and dietary needs. Keep in mind that substituting the sweetener may change the overall nutritional information.
Choosing Apples
Granny Smith apples are your best bet. They are tart, firm, versatile for baking, and have the lowest sugar and carb content among common varieties. Granny Smith apples are readily available year-round.
Keto Granola Substitute
Sometimes keto Granola can be difficult to find and in some stores, expensive. There is no cheap alternative, but you can mix a bit of your own and use it in its place.
Mix the following and toast in the oven:
- 1/4 cup chopped nuts (almonds, walnuts)
- 1/8 cup seeds (pumpkin or sunflower)
- 2 tbsp shredded coconut or coconut flakes
- 1 tbsp chia seeds
- 1 tbsp Walde Farms Pancake syrup
- Dash of cinnamon
Substitutes will alter the nutritional information in the final recipe, and will need to be altered. Do not use a non-keto granola as a replacement if you want to remain low-carb.
How to Serve:
Serve these bars warm from the oven or chilled from the fridge. For a little indulgence, try topping with:
- A dollop of sugar-free whipped cream
- A scoop of low-carb vanilla ice cream
- A sprinkle of extra cinnamon or chopped nuts
- Whisk together a couple of tablespoons of Walden Farms Caramel or Pancake Syrup with 1/2 tsp of ground cinnamon and drizzle over bars before serving.
Freezing and Storing Instructions
Store sugar free apple crumble bars in an airtight container, refrigerated for 4 to 5 days or freeze in an airtight container for up to 2 months. When defrosting, for best results, place in a warm oven. For best results, place in an airtight container, cover snugly with plastic wrap and then cover with the lid. This limits the amount of air in direct contact with the surface of the bars.
These sugar free apple crumble bars are everything cozy and comforting, without the added sugar. Whether you’re baking for a diabetic-friendly holiday dessert table or just want something sweet and smart, this recipe checks all the boxes.
