Whisk together the powdered erythritol, matcha powder, and a pinch of salt in a small bowl until well combined. Transfer to a gallon-sized sealable bag.

Combine healthy matcha green tea white chocolate and roasted almond butter in a large microwave-safe bowl. Microwave in 15-second intervals, stirring until smooth (30-45 seconds).

Add Shredded Wheat cereal to the melted mix and gently fold until evenly coated.

Transfer cereal mixture into the bag with the dry matcha mix, seal tightly, and shake vigorously for about 30 seconds.

Spread the mixture onto a lined cookie sheet and chill uncovered in the refrigerator for at least 3 hours.

Once chilled, break into bite-sized portions and store in an airtight container in the freezer.
