Ingredients

• 2 1/2 cups rolled oats
• 1 cup candy-coated milk chocolate pieces (such as M&M;'s®)
• 1 cup all-purpose flour
• 1 cup flax seed meal
• 1/3 cup brown sugar
• 3/4 teaspoon salt
• 1 egg
• 1/2 cup honey
• 1/2 cup vegetable oil
• 1 tablespoon vanilla extract

Instructions

1. Preheat oven to 350 degrees F (175 degrees C).
2. Stir oats, milk chocolate pieces, flour, flax seed meal, brown sugar, and salt together in a large bowl. Make a well in the center of the oat mixture.
3. Whisk egg in a separate bowl until light and fluffy. Add honey, oil, and vanilla; whisk until well-combined. Pour egg mixture into the well in the oat mixture. Stir until evenly combined. Pour mixture into a 9x13-inch glass baking dish; pat down and spread the mixture flat, leaving at least 1-inch of space between the mixture and the sides of the dish.
4. Bake in the preheated oven until golden and set, about 25 minutes.
