This easy dessert is a fun way to use up oats. It comes out soft, chocolatey, with oats in every bite. It's only three ingredients and doesn't require flour, eggs or oil.
Spray the interior of a 6 inch springform pan. Line it with parchment paper (both bottom and inner sides. I used a pre-cut round piece for the bottom and then cut strips of parchment for the sides.)
Add chocolate and milk to a large microwave-safe mixing bowl. Heat at 1 minute intervals, whisking in between, until chocolate is completely melted and smooth. (I needed 2 minutes total). Alternatively, you can melt the milk and chocolate on the stove, using the double boiler method, but it will take a little longer.
Stir in oats until they are evenly combined and fully coated in the chocolate mixture. Your batter will be thick.
Pour batter into prepared cake pan. Use spatula to smooth surface and make sure the batter is evenly distributed across the cake pan.
Place cake into freezer for 30-60 minutes or until firm and set. Remove cake and let it come to room temperature before cutting and serving. Cake needs to come to room temperature before serving, otherwise the chocolate will be too firm. Uneaten cake can be stored in an airtight containe at room temperature for 1-2 days and longer in the fridge.
Notes
This cake is best made in a springform pan lined with parchment paper. Otherwise, it will be very difficult to remove. I used this 6-inch springform pan.*
You can use a bigger pan but your cake will not be as tall.
If you have questions regarding ingredient substitutions, please see the Ingredients section of the post for more details.
This cake is sweet but not super sweet. For a sweeter cake, you can use milk chocolate instead of semi-sweet chocolate. I don't recommend bittersweet chocolate because your cake will not be sweet enough.
