Monster Cookies Bars Recipe

Ingredients:

  • ½ cup butter, softened
  • 1 cup brown sugar
  • ½ cup peanut butter

  • 1 teaspoon vanilla extract

  • 1 ¾ cups quick-cooking oats
  • ¾ cup semi-sweet chocolate chips

Instructions:

  1. Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking pan and set aside.
  2. In a large bowl, cream together the softened butter and brown sugar until smooth.
  3. Add peanut butter, eggs, and vanilla extract. Beat until fully combined.
  4. In another bowl, whisk together the flour and baking soda. Gradually mix the dry ingredients into the wet mixture until just combined.
  5. Fold in the oats, chocolate chips, and M&M candies until evenly distributed.
  6. Press the dough evenly into the prepared pan. Optionally, press a few more M&Ms on top for a colorful finish.
  7. Bake for 14 to 16 minutes or until edges are lightly golden and a toothpick inserted comes out clean. Avoid overbaking for the best chewy texture.
  8. Let the bars cool in the pan for 20 minutes. For clean cuts, allow them to cool completely before slicing.

20 Most Popular Questions & Answers

1. Can I use old-fashioned oats instead of quick-cooking?
Yes, but pulse them in a food processor a few times to break them down slightly for better texture.

2. What if I don’t have peanut butter?
Try almond butter, sunflower seed butter, or even Nutella for different flavors.

3. Can I make these gluten-free?
Yes! Substitute with a 1:1 gluten-free flour blend and ensure your oats are certified gluten-free.

4. How do I know when they’re done?
Edges should be lightly golden and center should look set but still soft. Don’t overbake!

5. Can I freeze these bars?
Absolutely! Wrap individually or store in airtight containers for up to 3 months.

6. Why are my bars falling apart?
Likely underbaked or cut too soon. Let them cool completely before cutting.

7. Can I use different candies?
Yes! Try Reese’s pieces, mini chocolate chips, or chopped candy bars.

8. How long do these keep?
Store covered at room temperature for up to 1 week, or refrigerate for 2 weeks.

9. Can I make these dairy-free?
Use vegan butter and dairy-free chocolate chips. Check that your M&Ms are dairy-free alternatives.

10. What’s the best way to cut clean bars?
Use a sharp knife, wipe between cuts, and cut when completely cool.

11. Can I double this recipe?
Yes, but you’ll need two 9×13 pans or one large sheet pan. Adjust baking time accordingly.

12. Why are my bars too dry?
Likely overbaked. Reduce baking time by 1-2 minutes next time.

13. Can I add more mix-ins?
Yes, but don’t exceed 2½ cups total mix-ins or the bars may not hold together.

14. What if I only have crunchy peanut butter?
It works fine and adds extra texture! You might want to reduce other crunchy elements slightly.

15. Can I make these without eggs?
Try using flax eggs (2 tbsp ground flaxseed + 6 tbsp water) or commercial egg replacer.

16. How do I prevent sticking to the pan?
Line with parchment paper or use cooking spray plus flour dusting.

17. Can I make individual cookies instead?
Yes! Drop spoonfuls on baking sheets and bake for 10-12 minutes.

18. What’s the best brown sugar to use?
Light brown sugar works best, but dark brown adds more molasses flavor.

19. Can I reduce the sugar?
You can reduce by up to ¼ cup, but texture and sweetness will be affected.

20. Why do my M&Ms sink to the bottom?
Toss them in a little flour before folding in, or press some on top before baking.
