In a medium-sized mixing bowl, combine the softened cream cheese and mayonnaise using a hand mixer or spoon until smooth and creamy. This should take about 2-3 minutes.

Next, sprinkle in the garlic powder, onion powder, and salt into the creamy mixture. Mix for another 1-2 minutes until fully incorporated, enhancing the flavor profile.

Gently fold in the chopped tamed jalapeños and roasted red peppers using a spatula. Continue folding until evenly distributed throughout the creamy base—this should take about 1-2 minutes.

Stir in the shredded white cheddar cheese, allowing it to mingle with the dip's base. This should take around 1 minute until the cheese is evenly incorporated.

Cover the bowl with plastic wrap or a lid and place it in the refrigerator to chill for at least 30 minutes to meld the flavors.

When it's time to serve, stir to re-combine any layers and transfer to a decorative platter. Pair with crackers, pretzels, or crunchy vegetable sticks.
