Step-by-Step Cooking Instructions for Peanut Butter Cookie Baked Oatmeal
Pre-Cooking Prep for Peanut Butter Cookie Baked Oatmeal
Begin by gathering all ingredients and allowing them to come to room temperature, especially the peanut butter and milk. This ensures smooth mixing and even baking. Preheat your oven to 350°F (175°C) and lightly grease your ramekin or small baking dish.
Mixing Method for Perfect Peanut Butter Cookie Baked Oatmeal
In a medium bowl, combine the oats, baking powder, and salt. In a separate small bowl, whisk together the milk, peanut butter, maple syrup, and vanilla until smooth. The peanut butter should be completely incorporated no streaks or lumps.
Pour the wet ingredients over the dry ingredients and stir until just combined. Don’t overmix; a few lumps are perfectly fine. Fold in your chosen mix-ins gently.
Baking Technique for Peanut Butter Cookie Baked Oatmeal
Transfer the mixture to your prepared ramekin and smooth the top gently. The surface should be relatively even but doesn’t need to be perfect rustic charm is part of this dish’s appeal.
Doneness Check for Peanut Butter Cookie Baked Oatmeal
Bake for 22-28 minutes, until the center is set and the edges are lightly golden. The top should spring back slightly when touched, and a toothpick inserted in the center should come out with just a few moist crumbs.
Resting Your Peanut Butter Cookie Baked Oatmeal
Allow the oatmeal to cool for 3-5 minutes before serving. This brief rest helps the texture settle and prevents burns from the hot dish.
Pro Tips for Perfect Peanut Butter Cookie Baked Oatmeal
Avoiding Dense or Dry Peanut Butter Cookie Baked Oatmeal
The most common mistake is using too little liquid or overbaking. Your mixture should be pourable but not thin. If it seems too thick, add milk one tablespoon at a time. Check for doneness at 22 minutes every oven is different.
Essential Tool Recommendations for Peanut Butter Cookie Baked Oatmeal
A 6-8 ounce ramekin is ideal for this single serving. Ceramic holds heat beautifully and creates even browning. A small whisk helps incorporate the peanut butter smoothly, and a rubber spatula ensures you get every bit of batter into the dish.
Storage & Reheating Your Peanut Butter Cookie Baked Oatmeal
While best enjoyed fresh, leftovers keep in the refrigerator for up to 2 days. Reheat in the microwave for 30-45 seconds, adding a splash of milk if needed to restore moisture.
