Stir the base: In a bowl, whisk together the peanut butter, Greek yogurt, and heavy cream until smooth and creamy.
Sweeten and flavor: Add the sweetener, vanilla extract, cinnamon, and a small pinch of salt.
Mix well to evenly distribute the flavors.
Thicken it up: Sprinkle in the chia seeds and ground flaxseed. Stir thoroughly so there are no dry pockets.
Adjust the texture: Add almond milk 1 tablespoon at a time until you reach your preferred thickness. It should be spoonable, like pudding.
Let it rest (optional but recommended): Let the bowl sit for 5–10 minutes so the chia and flax can swell and thicken.
For an even thicker, mousse-like texture, chill for 30 minutes.
Add toppings: Finish with a few keto-friendly toppings for crunch and extra fat. Keep it light to stay low carb.
Serve: Enjoy immediately, or cover and refrigerate for later.
