This Baked Oatmeal Treat Recipe by Lemon Tree Dwelling is a hearty and delicious, filled with oats recipe. Perfect for breakfast or everyday snacks!

Hello and Happy New Year, Friends! It’s Cathy from Lemon Tree Dwelling, here today to share this delicious Trailside Treat Baked Oatmeal with you. This recipe is perfect because it feels like a treat, but it’s actually just oatmeal with a twist! It’s a great recipe to make ahead and share with friends, or keep in the fridge so you’ll have breakfast for the week. You can’t go wrong with chocolate chips…..especially for breakfast, am I right?

It’s based on one of my favorite cookies from childhood – Trailside Oatmeal Treats! Have you had them? They’re hearty and delicious, filled with oats and peanut butter and chocolate chips and raisins. Kind of like a granola bar, in cookie form. And now, in baked oatmeal form!

Just measure, stir, cook, and pour….then bake….and breakfast is served. And if the kids want to help? Even better! This is the perfect recipe for them to help with. Doesn’t it look amazing??? It’s like eating a cookie for breakfast, only it’s guilt free. It doesn’t really get better than that!

    These look amazing but all I have at home is quick oats and I live 20 min from town…can I do these with those? Leave out the stove part maybe and just mix?

    Could these be frozen and reheated?
