Japanese-style peanuts coated in a crunchy soy-seasoned shell are a Mexican snack staple. This high protein, family-friendly treat is a fresh, crunchy option for satisfying snack cravings.
Preheat your oven to 325°F (160°C) and line a large baking sheet with parchment paper. Set aside.
In a medium bowl, whisk together flour, cornstarch, baking powder, salt, and sugar until well combined.
In a separate small bowl, beat the eggs and mix in soy sauce until fully combined.
Add raw peanuts to the egg and soy mixture, coating all peanuts evenly. Then gradually add the dry ingredient mixture, tossing and stirring to coat peanuts and form a thick, clumpy shell. Gently break apart large clusters with a spoon or hands.
Spread the coated peanuts in a single layer on the prepared baking sheet and drizzle with neutral oil. Bake for 40-45 minutes, stirring every 10–15 minutes for even color and crunch. Watch closely near the end to prevent over-browning. Let cool before serving.
