Melt 1 package of miniature marshmallows with 1 tablespoon of canola oil in a microwave-safe bowl for 30 seconds, stirring until melted and smooth.

Fold in 5 cups of Rice Krispies cereal, 5 crushed graham crackers, 1 cup of chopped salted roasted almonds, and 1 cup of semisweet chocolate chunks.

Transfer the mixture into a greased 13x9-inch baking pan and press down evenly.

Allow to cool at room temperature for about 10-15 minutes until firm.

Melt the remaining package of semisweet chocolate chunks in the microwave for about 30 seconds and stir until glossy.

Drizzle melted chocolate over the cooled base and sprinkle with remaining mini marshmallows, chopped almonds, and chocolate chunks.

Let sit for about 10 more minutes to set, then slice into squares or bars to serve.
