Vegan, gluten-free Oreos that taste just like the real deal with a crispy, chocolaty cookie and sweet, creamy filling! Perfectly snackable, SO delicious, and made with just 7 ingredients!
Preheat your oven to 350 degrees F (176 C) and line two baking sheets with parchment paper.
COOKIES: In a medium bowl with an electric mixer, beat together softened refined coconut oil and cane sugar on medium speed until light and fluffy, 1-2 minutes. Next, mix in the cassava flour, cocoa powder, baking powder, and sea salt until a crumbly dough forms. Then add the lesser amount of water and mix until fully combined. The dough should easily hold together when squeezed — add more water if too dry and more cassava flour if too wet (we started with 4 Tbsp of water, but ended up adding another 1 Tbsp). Form the dough into a cohesive disk and place it onto a piece of parchment paper.
Move the dough to the center of the parchment paper and place another piece of parchment on top of it. Use a rolling pin to roll the dough out to 1/8-inch thick. Use a 2-inch cookie cutter to cut the dough into circles. Use a spatula to place the cookies about 1 inch apart on the baking sheet. Roll up the scraps and repeat with the remaining dough.
Ensure all the cookies are arranged about 1 inch apart on the baking sheets. Bake the cookies in batches on the center rack for 10-13 minutes. The cookies should feel set yet very slightly soft. They will firm up as they cool. Cool the cookies on their tray for 5 minutes, then transfer to a wire rack to fully cool.
FILLING: To a medium mixing bowl, add softened coconut oil and powdered sugar. Using an electric mixer, beat the filling starting on low speed and working your way up to high until it looks like thick frosting. Set aside.
When the cookies are completely cool, use the back of a knife or a spatula to place about 1 heaping tsp of filling on the bottom of one cookie and use another to create a sandwich.
Store leftover cookies in an airtight container at room temperature for up to 4-5 days. They also freeze well! Let thaw at room temperature before eating.

Notes
*Vegan butter works in place of coconut oil in the cookie portion only. It contributes too much flavor to the filling. *Cassava flour sub: 1 cup (160 g) MB 1:1 GF Blend works well in place of the 3/4 cup (96 g) cassava flour, but it requires chilling the dough for 10-15 minutes at the end of step 2. Other gluten-free blends (including our DIY blend), might also work, but we suggest comparing the consistency of the dough to the photos and adding more flour if needed. *Nutrition information is a rough estimate.
