Cinnamon Date & Walnut Baked Oatmeal

Oh baked oatmeal, how do I love thee? Let me count the ways… There’s Cranberry Apple, Banana Bread, Lemon Raspberry, Pumpkin Pie, and let us not forget Blueberry Banana. With each flavor I fall deeper in love with your warm, filling, and flavorful breakfast ways.

In this version, rich walnuts and warm cinnamon compliment small bits of naturally sweet chopped dates to create a perfect breakfast for cold winter mornings. As usual, this baked oatmeal is a breeze to whip up and is enough to provide you with easy-to-reheat breakfasts for the rest of the week. Just portion the oatmeal into single serving containers after baking and refrigerate until ready to eat. It can be enjoyed cold or warmed quickly in the microwave… because who wants to get out of bed early enough to prepare breakfast when it’s all cold out but toasty and warm under your covers? Not me.

People often mistake the baked oatmeals for being crunchy based on the pictures, but it’s soft, almost like a bread pudding. Not gooey like regular oatmeal, but not hard. The edges get a little chewy like the edges of baked brownies, but overall it’s pretty soft… soft and totally delicious!

Step by Step Photos

Wet Ingredients

Preheat the oven to 375 degrees. In a large bowl whisk together 1 1/2 cups yogurt, 2 large eggs, 1/2 cup brown sugar, 1 tsp vanilla extract, 1 tsp baking powder, and 1/2 tsp salt. It’s easier to whisk together these thicker ingredients first and then add the milk later—less splishy-splashy.

Add Milk

Once that mixture is smooth, pour in 1 1/2 cups milk and whisk again until smooth.

Walnuts and Dates

I used about 1/2 cup of walnuts and 1/2 cup of dried dates. I bought both from the bulk bins at the grocery store so that I wouldn’t have “leftovers” of each. I like to buy just what I need.

Rough Chop

Give them a rough chop. Smaller pieces mean you’ll get some in each bite… but you don’t want the pieces to be so small that you don’t notice them when eating. 

Oats Walnuts Dates

Add the chopped walnuts and dates, plus 3 cups of old-fashioned rolled oats to the milk mixture. Stir it all up good.

Ready to Bake

Pour it into an 8×8 or 9×9 inch casserole dish (coated with non-stick spray for easy clean up). The oats don’t really expand at all while baking, so it’s okay if your dish is a little more full than mine (this is a 9×9 inch dish).

Baked Oatmeal

Bake for 45 minutes, or until the center is no longer liquid. Eat it warm or refrigerate it for the rest of the week. :D
