Unfortunately-- most of her recipes are not safe for our gluten and dairy free community.

chocolate peanut butter layer brownies ingredient list

  • dairy free butter-- our go-to is Earth Balance Buttery Sticks in the red box. These are soy free too.
  • Dutch processed cocoa butter-- we use the Rodelle brand available here for purchase. The original recipe calls for unsweetened cocoa powder. We've found there can sometimes be an acidic aftertaste with unsweetened cocoa powder, so we stick with Dutch process cocoa powder. We reached out to the Rodelle company concerning their ingredient and manufacturing processes. Here is their response: “Rodelle Inc. does utilize raw materials that are considered to be major food allergens recognized by the US Food and Drug Administration and Health Canada. These include: wheat, soy, milk, mustard, sesame, and sulfites. These raw materials are not normally utilized in / on any equipment in common with Rodelle Gourmet Baking Cocoa. Rodelle takes great care to prevent cross contamination by following an allergen control testing program. It is packaged in a room separate from the rest of our facility. Upon completion of any allergen containing product, all equipment is cleaned and visibly checked for cleanliness. The equipment is also swabbed using ATP technologies. All ATP swabs must measure “0†or the equipment is re-cleaned. Periodically, equipment is tested with ELISA technology to validate cleaning as well.â€
  • granulated sugar
  • gluten free all purpose flour-- our favorite brand is Bob's Red Mill Gluten Free 1 to 1 Baking Flour. We purchase it in bulk here and save so much money.
  • xanthan gum-- omit if your gluten free flour blend contains this or gaur gum
  • salt
  • eggs-- large and at room temperature
  • vanilla extract
  • peanut butter-- creamy or crunchy; we love the crunchy peanut butter taste best in this recipe. We have not tested this recipe with natural peanut butter brands.
  • large marshmallows-- Dandies are a popular gluten and dairy free brand available for purchase here
  • powered sugar
  • dairy free milk-- we use unsweetened almond milk
  • 9x13-inch baking pan
  • nonstick spray
  • angled spatula-- this makes spreading the peanut butter and chocolate marshmallow frosting so easy to get around the edges and corners evenly
  • optional flaky sea salt-- sprinkle on a light layer to boost the flavor of these bars

can this recipe be made ahead of time

YES! It's a wonderful part of this recipe and why we bake it so often in our home. We absolutely love recipes we can prepare ahead of time.

Because this recipe calls for a longer prep time while the layers set in the freezer, we usually make this over the course of a day and store it in the freezer until we're ready to serve it.

how is this recipe different from the Magnolia Table Volume 2 Cookbook

Joanna's recipe uses traditional ingredients those of us in the gluten and dairy free community aren't able to bake with.

So our allergen friendly recipe uses only safe ingredients. And we also made a few adjustments to other ingredients.

Lastly-- we've tried this recipe with creamy peanut butter. And I can't believe we're admitting to this, but the recipe was too rich. And the original recipe calls for quite a bit more peanut butter. It was just too much.

So we made the switch to using crunchy peanut butter and using much less.

And by replacing the creamy peanut butter for crunchy, these dessert bars are perfection! Absolute perfection, y'all.

what's the difference between Dutch-processed cocoa and unsweetened cocoa powder

Have you ever bitten into chocolate baked goods and tasted a weird acidic flavor? That is oftentimes from unsweetened cocoa powder.

On the other hand Dutch-processed cocoa is treated with an alkali to neutralize its acidity so you don't have that unfortunate eating experience.

What if I am just dairy free? If I use all purpose flour, do I need to add xanthum gum?

Thank you for reaching out. No xanthan gum is needed. Omit that from the recipe. Cheers, Jill
