My Grandma’s Chocolate Crumble Bars Made GF

As much fun as the Valentine’s Day event was, I’m excited to get back on a normal schedule around here! I have a lot of posts lined up for the next few weeks including some fun surprises. So get ready for lots of fun times ahead.

The reason why I share a lot of baked goods on the blog is because I have a major sweet tooth. Like really major sweet tooth and I’m not the only one. I grew up in a family where yummy desserts were around ALL the time (I’m not complaining). One of my all time favorite goodies are these delicious Chocolate Crumble Bars that my grandma used to make. They are delicious. Filled with cake, crunch and my two favorite flavors chocolate and peanut butter. Since my grandma lived across the country, my mom took on the duty of making these bars throughout the year and let’s just say I was a little disappointed when I became GF and couldn’t eat them any more.

I’ve been gluten-free for 2 1/2 years and I can’t believe I am JUST now remaking these GF. I had to make them a few different times and I think I finally got it! The only thing missing is my grandma to share them with. Miss her so much.


1/2 cup Butter Soften

3/4 cup White Sugar

3 tsp. Egg Replacer + 1/4 cup water (or 2 eggs)

1/2 tsp. Salt

2 Tbsp. Cocoa

1 tsp. Vanilla

3/4 cup Gluten-Free Flour (I use Bob’s Gluten-Free All Purpose Flour Mix)

1/4 tsp. Baking Powder

1/2 tsp. Xanthan Gum


1 cup Peanut Butter

1 cup Chocolate melted*

1 cup GF Rice Krispies

1/2 bag mini marshmallows

* Since I am also soy-free I have a hard time finding baking chocolate that is soy-free and not super expensive. For this recipe, I used unsweetened chocolate squares and then sweetened them using this technique here. The chocolate was a little more bitter than a semi-sweet but it was still good!


1. Mix all ingredients together and pat into a greased 9 X 13 pan. One trick my momma taught me is to sprinkle a little powder sugar on top of the greased pan, it helps the crust from sticking and absorbs into the cake so you don’t see it like flour!

2. Bake at 350 degrees for 15 minutes

3. Sprinkle half a bag of mini marshmallows on top of the cake crust and bake for another 3 minutes or until marshmallows are puffy but not browned.

4. Let the pan cool thoroughly.

5. Meanwhile, melt the chocolate and peanut butter together and stir in the Rice Krispies.

6. Allow the bars to set for 12-24 hours until you serve (trust me, it makes a big difference).

Hope you enjoy them as much as I do.

    These sound so yummy! I cant wait to try them…do you usually make them in the evening or morning? I don’t know if I will be able to wait 12 -24 hours to try them!!! :) If I make them in the evening, then they can at least sit overnight…

      Welllll, if I make them during the day I don’t have any patience and I end up digging into them when they aren’t ready. Which makes a big mess. I try really hard but they are SO tempting! So making them at night is much better because they actually have time to set. I can’t stress enough how much better they are once they have set up :)

    Those look really good, I especially love the idea of the rice krispies for a little crunch! They look so chocolaty and gooey! Love it!

      OH I am definitely going to try your mix! I’m always on the look out for something new. I haven’t experimented much with different flour mixes because I enjoy Bob’s a lot, but should really branch out :)

    These sound so good! But I was just wondering … if I don’t have to worry about being GF can I make any changes to this recipe so I can make it? I don’t have any GF flour, and I don’t have any Xanthum gum. I plan to try it in the future, but I don’t want to be kept from trying this recipe in the meantime! Can I just substitute the same amount of regular flour and eliminate the Xanthum gum?
