Homemade Oatmeal Cream Pies
I had to save the best for last this week. Oatmeal Cream Pies were my all time favorite. There’s just something about that soft chewy oatmeal cookies with the cream filling smooshed between.
I have a confession to make about the store bought version of this cookie. When I was in High School, I was the yearbook editor senior year with a good friend of mine K. He and I had a class period each day to do yearbook work as an independent study class. We had the yearbook room to ourselves for one hour a day. It was a lot of fun. We kept Oatmeal Cream Pies in the yearbook drawer and would house these things on a regular basis. We’d go through a disgusting amount of these cookies in one hour. Thank goodness for my high-school metabolism (which has since vanished), as well as my stomach of steel. Oh man, parts of high school were a good time.
Back to reality. In the past 10+ years since then, my stomach has become more sensative to dairy and other foods, and I have to work to not gain weight. I’ve learned a lot about how to eat healthy and gained quite the love of cooking and baking. I’ve also learned that most store bought foods can be made a hundred times better at home.
These cookies are no exception. The brown sugar in the cookies keeps them perfectly soft and the filling is so much better than what’s in the store bought version. It’s like a homemade marshmallow fluff, and it’s amazing. I packaged them in celophane bags so they were easy to throw into lunches for me and Hubby this week.

Homemade Oatmeal Cream Pies
Yield: 24
Ingredients:
For the Cookies
3/4 cup unsalted butter, softened
2 cups packed brown sugar
2 eggs
1/2 tsp salt
2 cups flour
1 tsp baking powder
1 tsp ground cinnamon
2 cups quick-cooking rolled oats
2 tsp baking soda
3 Tbsp boiling water
For the Filling
1 Tbsp plus 1 tsp unflavored gelatin (about 1 1/2 packets)
1/3 cup plus 1/4 cup water (divided)
3/4 cup sugar
1/2 cup light corn syrup
2 tsp vanilla
1 cup powdered sugar
8 ounces vegetable shortening
Directions:
Make the cookies
Preheat the oven to 425 degrees F. Lightly grease a baking sheet and set aside (or use parchment).
Cream the butter, sugar, and eggs in a large bowl.
In a separate bowl, sift together the salt, flour, and baking powder. Add to the creamed mixture. Add the cinnamon and oats. Mix well.
In a small dish, add the baking soda to the boiling water, and then stir the mixture into the rest of the batter. Mix well.
Drop by the tablespoon onto the baking sheets about 2 inches apart and bake until the cookies are firm and just starting to turn golden around the edges, 10 to 15 minutes. Cool the cookies on a wire rack or a plate.
Make the filling
In a small measuring cup, sprinkle the gelatin over 1/3 cup cold water. Let stand, stirring once or twice until the gelatin softens, about 5 minutes.
In a heavy 2-quart saucepan over medium-high heat, stir together the granulated sugar, corn syrup, and 1/4 cup hot water until well blended. Continuing to stir, raise the heat to high and bring to a full boil. Continue boiling for 30 seconds. Immediately remove from the heat. Stir in the gelatin mixture until it dissolves completely.
Transfer the mixture to a large bowl. Add the vanilla.
With a mixer on medium speed, beat for 20 seconds. Gradually raise the speed to high and beat until the mixture is stiffened, white, very fluffy, and cooled to barely warm, about 5 minutes.
Reduce the mixer speed to low and gradually add the powdered sugar.
Add the shortening and beat until completely smooth.
The filling will set up as it sits, so wait until it is thick enough to spread or pipe before filling the cookies.
Recipe from How to Eat a Cupcake
How cool! These look delicious!
This totally takes me back to childhood. We ALWAYS used fresh rhubarb from our backyard to make yummy breakfast treats!
I think I will have to make these for my parents next time they visit. They will LOVE them!
Those look amazing! I’m always on the lookout for new rhubarb recipes, the season for it is so short in Western Ma, that I tend to buy WAY too much and stick in the freezer..
I have never had rhubarb before, but these look great!
They’re so pretty – I love family recipes!
I never know what to do with Rhubard, but these looks awesome!
divine. i want one. right now. pretty please?? 🙂
I love your recipes, lactose free and awesome, I will def. have to try this. Ps. we should team up and do something lactose free together in solidarity!
Thanks everyone – seriously if you have rhubarb hanging around. Make these. You won’t regret it.
I’m a little lost. The ingredients list mentions 5 c. rhubarb (and you break it into 3 c. for the filling and 2 c. for the sauce) but I don’t see in the step-by-step instructions when/where/how the 2 c. of rhubarb are used. Please help!
Thanks!
alexandjess – thanks for catching my mistake. I added the instructions about the sauce into the post, but you make the sauce by boiling 2 cups cut rhubarb, 1 cup sugar, 1 1/3 cups water. The rhubarb for the sauce can be cut in large chunks because it all falls apart anyways.
Your sisters made the rhubarb rolls and stuffed dates yesterday for our Memorial Day cookout. They were delicious!!!! Can’t wait to have another piece tonight for desert. I have a new recipe for potato salad that is delish….let me know if you want me to pass on.
i made these tonight and they went awry for a series of reasons that were my fault and won’t go all into…. one thing i did though was use half rhubarb and half strawberries, which sounded delish but i didn’t cut the sugar enough and i think that also made things more watery. my question though, is whether by ‘shortening’ you specifically mean something like crisco or whether you just mean butter or margarine or anything like that. i used butter and didn’t see how i could get away with a little ‘stirring’ before rolling. i tried to cut it in with a pastry blender, but in the end maybe that was too much action for the dough as it seemed a little gummy after cooking….
i’d appreciate any advice!
natasha – I use Crisco for the dough. I think that’s what my dad always uses as well. Hopefully that is what caused the gumminess. Sorry they didn’t turn out for you.
My family has been making these for years. I have used butter or margarine to cut into the flour mixture for the dough and have never had a problem. I always roll my dough out into a rectangle and when I cut the rolls they NEVER look as neat as the ones you have pictured! I have added strawberries but only in the sauce. My mom liked to add red food coloring to make it look more rosy. We bake for 20 minutes before pouring on the sauce and then another 20 minutes. I have to make it every spring in honor of my mom.
my grandma recipe calls thesr soringtime rollypoly, and can ad what ever frozen berries you have , frozen is the least messy
sorry thats springtime rollypolly
