Ingredients You’ll Need
Nothing complicated. Promise.
Dry Ingredients
- 1½ cups rolled oats – Old-fashioned works best.
- ¼ cup unsweetened cocoa powder – Go for good-quality if you can.
- ¼ tsp salt – Chocolate’s best friend.
Wet Ingredients
- ¼ cup honey or maple syrup – Just enough sweetness.
- ¼ cup unsweetened applesauce – Moisture without extra calories.
- ¼ cup milk of choice – Almond, skim, oat, whatever you like.
- 1 tsp vanilla extract – Makes it taste like dessert.
Optional but excellent:
- 2 tbsp dark chocolate chips – Because life.
- 1 tbsp nut butter – Adds richness (still low-cal if you’re gentle).
Key tip: Measure cocoa carefully. Too much and things get bitter fast.
Step-by-Step Instructions
- Preheat oven to 350°F (175°C).
Line a small baking dish with parchment paper. - Mix the dry ingredients.
Combine oats, cocoa powder, and salt in a bowl. Stir well. - Mix the wet ingredients.
In another bowl, whisk honey (or maple syrup), applesauce, milk, and vanilla. - Combine wet and dry.
Pour wet ingredients into dry and mix until everything is evenly coated. - Add optional extras.
Fold in chocolate chips or nut butter if using. - Press into baking dish.
Spread evenly and press down firmly. This helps the bars hold together. - Bake for 15–18 minutes.
Edges should look set, but the center will still be soft. - Cool completely before slicing.
This part matters. Warm bars = crumbly chaos.
Common Mistakes to Avoid
- Overbaking.
These bars firm up as they cool. Take them out early. - Not pressing the mixture firmly.
Loose pressing = bars that fall apart. - Using instant oats.
Texture turns mushy. Rolled oats are the move. - Skipping parchment paper.
Trust me. Don’t. - Expecting them to taste like brownies.
They’re oat bars, not fudge. Adjust expectations.
Alternatives & Substitutions
Make them yours.
- Gluten-free:
Use certified gluten-free oats. - Vegan:
Use maple syrup and plant-based milk. - Higher protein:
Add 1–2 tbsp chocolate protein powder. FYI, add a splash more milk. - Extra crunch:
Add chopped almonds or walnuts. - No bake option:
Chill in the fridge for 1–2 hours instead of baking (texture will be softer).
IMO, keeping them simple lets the chocolate flavor shine.
