Recent Health Research
A 2023 study published in the journal Nutrients found that a well-formulated ketogenic diet supplemented with anthocyanin-rich berries (like blackberries) significantly improved cognitive function in adults with mild cognitive impairment. The researchers, led by Dr. Maria Kontogianni, observed enhanced memory performance and executive function after just 12 weeks, attributing these benefits to reduced neuroinflammation and improved insulin sensitivity in brain tissue. This recipe’s combination of low-carb structure with blackberries’ natural polyphenols mirrors the study’s successful intervention approach.

FAQs
Q: What are the approximate macros for one serving?
A: Each 105g serving contains exactly 275 calories, with approximately 24g fat, 7g protein, and only 4g net carbs, making them perfectly aligned with keto macronutrient goals.
Q: I don’t have instant clear jel. What can I use instead?
A: You can substitute with 1 teaspoon of unflavored gelatin bloomed in 1 tablespoon of cold water for each 1/2 teaspoon of clear jel. Alternatively, 1/4 teaspoon of xanthan gum will work, though the texture will be slightly different.
Q: Can I make this dairy-free while keeping it keto?
A: Yes! Substitute the cream cheese with a nut-based version, use coconut cream instead of heavy cream, and replace butter with coconut oil. The texture will be slightly different but still delicious.
Q: How far in advance can I make these bars?
A: These bars actually taste better after 24 hours when flavors have melded. They can be made up to 3 days in advance and kept refrigerated. The crust may soften slightly over time but will still maintain structural integrity.
Q: Are frozen blackberries acceptable to use?
A: Yes, though they release more moisture. Thaw and drain them first, then reduce the added water to 1 tablespoon in the blackberry layer recipe.
Q: Why do you recommend allulose over other keto sweeteners?
A: Allulose dissolves completely without crystallizing when chilled, delivers a more sugar-like mouthfeel, and doesn’t contribute to the cooling effect often experienced with erythritol or the potential aftertaste of stevia.
Q: Can I use an 8-inch pan instead of 9-inch?
A: Absolutely! Using an 8-inch pan will create thicker, more substantial layers. This will yield 9-12 servings with approximately 105g per serving when cut into 12 portions.
