Super simple and supremely chocolaty, these chocolate oatmeal cookies are stuffed to the brim with chocolate chip goodness.
1/2cup1 stick unsalted butter, room temperature*
1cuppacked dark brown sugar
1 1/2cupsrolled oats
1cupdark chocolate chipssemi-sweet are also good
Preheat the oven to 350 degrees Fahrenheit. Line a baking sheet with a silicone mat (a non-stick sheet will also work just fine, I just like the ease of the silpats).
In the bowl of an electric mixer fitted with a paddle attachment, or in a large bowl using a hand mixer, beat together the butter and the brown sugar until pale yellow and fluffy, about three minutes.
Add egg and vanilla, and beat until blended.
In a medium bowl, whisk together the flour, cocoa powder, salt, and baking soda.
Add to the wet ingredients in the mixer bowl and mix just until combined. Add rolled oats and chocolate chips and mix just until combined, scraping down the sides as needed.
Scoop by tablespoonful onto your cookie sheet, spaced about two inches apart.
Bake for about 10 minutes, until cookie appears set and no longer wet. They might not look completely done, but they'll set up after they cool! If you like a crisper, less chewy cookie, let them cook for 2 - 3 minutes longer.
Remove from oven and let sit for about 5 minutes, then move to a wire rack to cool completely.
They keep nicely for 4 - 5 days in an airtight container at room temperature, or you can freeze them in a zipper bag for several months.
