Dubbing herself Farmer Jen in the clip, she could be seen sitting in a field in Locust Grove, Oklahoma wearing striped overalls over a fitted shirt that she paired with booties. She also had a bunch of pumpkins sitting in her lap.

"Wait until you try @onceuponafarm’s Farmer Jen’s Pumpkin Oatmeal Cookie! It tastes like autumn— cinnamon, vanilla, creamy pumpkin— oats blended right in for added richness. All of this flavor with no added sugar— it’s bananas (Truth! there is actually a banana in the blend for sweetness)," she captioned the clip.

"This blend is even more special— we grew some of the pumpkins on my family farm, AND donations from Farmer Jen’s blends go toward our commitment to serving one million meals to kids in need through @savethechildren  I told you it was bananas!"

The "cookie" is actually a nutrition-packed cold-pressed snack that is organic, non-GMO and has no added sugar like the company’s other snacks and baby food. So, the pre-made snack tastes like a cookie, but it doesn’t go in the oven, and it’s healthy too. 

"I’m so proud and excited," Jennifer said in the clip about her company’s charitable initiative, before kissing the pumpkins she had sitting in her lap.
