How to make chocolate oat bars
Make these dark chocolate oatmeal bars in only a few easy steps. Here’s how it’s done:
Step 1 - Heat the milk and pour it over the chocolate.
Step 2 - Stir until it melts and creates a thick, smooth, melted chocolate sauce.
Step 2 - Mix up the oaty cookie dough in a bowl.
Step 3 - Pack some of the dough into the bottom of a lined loaf pan.
Step 4 - Pour the dark chocolate sauce on top of the dough to form the chocolate layer.
Step 7 - Crumble the rest of the cookie dough over top of the chocolate then bake.
Step 8 - Allow to cool in the pan then carefully remove and slice into bars with a sharp knife.
Success Tips
- Leave the dark chocolate oatmeal bars to cool completely in the loaf pan before cutting them. The chocolate layer needs to set.
- Press the cookie dough to the pan using the bottom of a mug or glass or your hands. The tighter it’s packed, the more your bars will hold together.
- Use a sharp knife to safely and easily cut the bars. Run the blade under hot water for a few seconds for a smooth slice.
- This recipe makes big and filling bars. Feel free to cut each slice in half if you want smaller portions.
Ways to adapt this dessert bar recipe
- Use jam, apple butter, or pumpkin butter instead of the chocolate layer.
- Add some shredded coconut, chocolate chips, raisins or chopped nuts to the cookie dough mixture.

RECOMMENDED EQUIPMENT
INSTRUCTIONS
- Heat ½ cup / 120 mls of the milk, either in a pan on the stove or in the microwave until hot but not boiling. Remove from the heat.

- Pack about ⅔ of the dough into the bottom of the loaf pan really tightly and flatten it out.
- Pour over the chocolate mixture and give the pan a gentle shake to level it out.
- Crumble the rest of the dough evenly over the top of the chocolate layer.

- Once at room temperature, carefully remove from the pan using the parchment paper as handles, and slice into portions with a sharp knife.

Wow are these ever good! I used weight measurements and they turned out perfectly. The filling is amazing, like a decadent chocolate pudding. I have eaten way too many and only kind of regret it. I'll try making them in an 8x8 pan next time as the crust was pretty thick, and it will allow me to cut smaller pieces more easily. Also thinking peppermint in the chocolate might make a nice Christmas version. Thanks for the great recipe!
