Combine the ingredients: Preheat the oven to 350°F. In a large bowl, mix together all the ingredients (10 oz old-fashioned rolled oats, 2 tbsp all-purpose flour, 1/4 cup almond flour, 1/2 tsp cinnamon powder, 1/4 tsp salt, 1.5 oz pumpkin seeds, 1 oz cashews, 1/4 cup walnuts, 1 oz dried cranberries, 1 tbsp peanut butter, 1/2 tsp vanilla extract, 2 medium eggs, 3 tbsp brown sugar, 2 tbsp honey, 1/4 cup whole milk) until you get a thick dough.

Transfer to a baking pan: Line a baking pan with parchment. Add the dough to the pan and spread it out using a spatula greased with nonstick cooking spray.

Cut the dough: Using a knife greased with nonstick cooking spray, divide the dough into 20 equal pieces.

Bake in the oven: Put the baking pan into the preheated oven and bake for 35 minutes. Once done, remove from the oven and set aside to cool for at least 15 minutes.

Serve: Transfer the oatmeal bars to a plate and serve.
