Ingredients
• 3 tablespoons (45 ml / 1.5 fl oz) frozen blueberries
• 2 tablespoons (30 ml / 1 fl oz) almond flour
• 2 teaspoons Swerve sweetener
• 1 teaspoon (5 ml / 0.2 fl oz) baking powder
• 1 teaspoon (5 ml / 0.2 fl oz) cinnamon
• 2 large eggs, at room temperature

2. In a medium bowl, whisk together the almond flour, Swerve sweetener, baking powder, and cinnamon.
3. Add the eggs and shredded mozzarella to the dry . Stir until the batter is smooth and well combined, then gently fold in the frozen blueberries.

Pro Tips
• For the crispiest chaffles, let them cool on a wire rack for a minute or two after cooking. This prevents them from getting soggy from trapped steam.
• Use pre-shredded, low-moisture mozzarella cheese. Fresh mozzarella contains too much water and will result in a soggy texture.
• Don’t overfill the waffle maker. The batter will expand as it cooks, so a little less than you think you need is usually the perfect amount.
• Feel free to swap blueberries for other keto-friendly berries like raspberries or chopped strawberries for a different flavor profile.
FAQ
Q: How do I make my chaffles extra crispy
A: For the crispiest chaffles, use pre-shredded, low-moisture mozzarella cheese. After cooking, place the chaffle on a wire rack for a minute or two. This allows steam to escape and prevents the chaffle from becoming soggy.
Q: Can I use fresh blueberries instead of frozen
A: The recipe calls for frozen blueberries as they hold their shape better and release less water, ensuring a better texture. Using fresh blueberries may result in a soggier chaffle.
Q: Can I use a different type of berry in this recipe
A: Yes, you can easily substitute blueberries with other keto-friendly berries. Raspberries or chopped strawberries are excellent alternatives that work well in this chaffle recipe.
Q: Why is my chaffle batter portioned into five parts
A: This recipe is designed for a mini waffle iron. The batter makes approximately 5 mini chaffles, so dividing it into fifths ensures each chaffle is the perfect size and cooks through properly without overflowing the machine.
Pro Tips
- Fold the frozen blueberries in straight from the freezer — thawing them first makes the batter watery and the chaffles limp.
- Use slightly less batter than you think you need per chaffle; the batter expands as it cooks and a thinner layer crisps up much better.
- Cook until the chaffle is golden brown and no more steam escapes from the sides of the iron. That's when the inside is set and the outside is crisp.
- Rest cooked chaffles on a wire rack, not a plate, so steam escapes and they stay crunchy instead of going soft.
- Serve warm with a dusting of powdered Swerve. Leftovers keep 3 days in the fridge and toast back to crispness; they also freeze well for 2 months.
Frequently Asked Questions
How many carbs are in these blueberry chaffles?
Each of the 5 mini chaffles has about 3.5 g of total carbs with roughly 1 g of fibre, landing around 2.6 g net carbs per serving.
Can I use fresh blueberries instead of frozen?
Yes, fresh berries work fine — just fold them in gently so they don't burst and streak the batter. Frozen berries tend to hold their shape better.
Can I make these ahead for meal prep?
Absolutely. Cook the batch, cool it, and store the chaffles in the fridge for up to 3 days. Re-crisp them in a toaster before serving.
Is the mozzarella taste noticeable?
Not at all in the sweet batter — the cinnamon, berries, and vanilla-style toppings mask it completely. The mozzarella is there purely for the chewy texture.
