Gigantic Homemade Little Debbie’s Oatmeal Cream Pie Cake recipe is a spot-on version with soft, chewy cookie layers and fluffy white filling sandwiched between. If you are a fan of the Little Debbie’s oatmeal cream pies, you will not believe how much this cake nails all the flavors only SUPER SIZED!
Oh yes I did. My kids love Little Debbie’s oatmeal creme pies, and they will occasionally make a surprise appearance in their lunchbox. As I am dutifully packing their lunch I will think, “I want to inhale this oatmeal creme pie so bad.” But, I can’t because #1: it isn’t gluten free, and #2: even if it was, it probably wouldn’t taste the same and I would cry.
So I took matters into my own hands, and went straight for the motherload after all those years of depriving myself of a delicious snack cake staple. The cookie cake version saves me the trouble of making cookies and filling them all. Plus, let’s face it, I’d probably just inhale seven in one sitting anyway. Let’s just go for broke here.
I had the inspiration (Sally’s Baking Addiction-the cookie part is spot on), I had the venue to bring it to and share (otherwise, I would have likely convinced myself it’s just one cookie and ate the whole thing), but I still needed the filling. If you’ve checked out my Salted Chocolate Ganache Ding Dong Cake you know I am really particular about copycat recipes. It has to taste like the epitome of the food I’m replicating or I will get agitated instead of gloriously nostalgic.
I rifled through my food memory index, and recalled a trip we took when I was a little girl to Pennsylvania Amish country (yes, this was a trip we actually took, riveting, I know). Besides recollecting my mom humiliating us by not-so-surreptitiously taking pictures of the Amish families when it was clearly stated on all the literature not to, I remembered these colossal whoopie pies we ate at the farmer’s market. That is exactly what I wanted the filling to taste like – light, sweet, and airy instead of buttery, creamy, or gooey.
I decided to really stick it to Lil’ D for not suppling me with a delicious gluten free option all these years. I went absolutely berserk on the amount of filling. You might think, This girl’s bananas. That is an aggressive amount of filling. But I promise you, when slathered between two thick, chewy, molasses oatmeal cookies it is perfection.
In other news, our windows have become giant TVs for the Babies to see “Scooper trucks,” “Bucket trucks,” and “Bob da Builders” daily. Our house is under construction because we are transitioning from how-do-you-survive-with-all-those-humans-sharing-one-full-bath to an addition with amenities such as a garage I don’t have to carry a toddler through the snow to reach and a locking-door master bathroom so my kids don’t interrupt my private business on a daily basis.
Five months from now I will no longer lament, “It’s like I live in a frat house!” due stray urine everywhere and no sense of discretion. I’ll keep you posted on the progress, but you may see a lot more desserts (and cocktails) coming your way due to a long ride on the struggle bus.
Gigantic Homemade Little Debbie's Oatmeal Cream Pie Cake
- 1 1/4 cups (2 1/2 sticks) unsalted butter, softened
- 1 cup packed brown sugar
- 1/2 cup sugar
- 1 large egg
- 2 tsp. vanilla extract
- 1 tbsp. dark molasses
- 1 1/2 cups all-purpose flour or gluten free flour, I always use Cup 4 Cup gluten free flour
- 1 tsp. baking soda
- 1/2 tsp. salt
- 3/4 tsp. cinnamon
- 1/4 tsp. ground cloves
- 3 cups quick-cooking oats, NOT whole-rolled
- 2 egg whites
- 1 tsp. vanilla
- 4 tbsp. heavy cream
- 4 cups powdered sugar, divided
- 1 1/2 cups shortening
- Preheat oven to 350ºF. Spray 2 9" cake pans with cooking spray. Line each with parchment cut to size, and spray again. Set aside.
- With a stand mixer or handheld, cream the butter and sugars together at medium high speed until pale, light, and creamy, about 4 minutes. Add the egg, vanilla, and molasses. Mix well.
- In a separate bowl whisk together the flour, baking soda, salt, cinnamon, and cloves. Add the quick oats and combine.
- Gradually add the dry ingredients to the butter / sugar mixture until it is all incorporated. The batter will be very thick.
- Divide half the dough into each prepared cake pan. Press it down with your fingers and then use an offset spatula to smooth it evenly.
- Bake in oven 22-24 minutes. The edges should golden and set and middle soft still.
- Cool in pan for 10 minutes, then run a knife around the edge. To avoid the cakes cracking, put the wire racks on top of the cake pan, hold everything together, and then invert the wire rack. Cool completely.
- In a large bowl whisk together egg whites with 1 cup of powdered sugar. Place bowl over a pot of barely simmering water. Make sure bottom of the bowl isn't touching the water directly and should be sitting a few inches above. Whisk the egg whites and sugar continually over the pot of simmering water about 2-3 minutes, or until egg whites are hot to touch. Remove immediately from heat and let cool to room temperature.
- Whisk in the vanilla, heavy cream, and remaining powdered sugar until smooth.
- If using a stand mixer, switch to a paddle attachment, add shortening, and mix for 4 minutes on high until very light and fluffy.
- Slide one cookie onto cake stand or serving platter so top part of cake is facing down. Top with filling and place other cookie on top, so right side is up. It will seem like a lot of filling, but between the two cookie layers it seems like the perfect amount when you are eating it. <img draggable="false" data-mce-resize="false" data-mce-placeholder="1" data-wp-emoji="1" class="emoji" alt="<img draggable="false" data-mce-resize="false" data-mce-placeholder="1" data-wp-emoji="1" class="emoji" alt="?" src="https://s.w.org/images/core/emoji/2/svg/1f60b.svg">" src="https://s.w.org/images/core/emoji/2/svg/1f60b.svg"> Slice with serrated knife and enjoy!
