Hey Babes!

Let’s give poptarts an upgrade with sourdough.

I’m so excited for you to try these healthy sourdough poptarts {peanut butter + strawberry jam}. They’re UNREAL and absolutely delicious. The crust is soft and flakey and the inside is gooey with swirls of warm peanut butter and strawberry jam in every bite. I would say they’re a mix between a pb&j uncrustable and a poptart.

Honestly, I think it’s the best of both worlds AND they’re also healthy for you too!!

Healthy Sourdough Poptarts

You know I had to put my healthy spin on these sourdough poptarts too. Here are the deets:

  • Organic peanut butter.
  • A good quality strawberry jam, although next time I’m going to use my homemade strawberry chia jam. 
  • The dough is sourdough based so it’s gut healthy and nutritious
  • Topped with cinnamon instead of icing


What are the health benefits of “sourdough-ing” poptarts?

Sourdough bread and snacks (like these poptarts!) are unlike all other types of bread because they go through a long and slow natural fermentation with wild yeasts and lactic acid bacteria. This ancient, 6,000-year-old tradition has remarkable health benefits.  

  1. Supports Gut Health
  2. Activates B Vitamins and minerals, like iron, zinc, and magnesium
  3. Degrades gluten
  4. Synthesizes prebiotic fiber
  5. Boosts Antioxidants
  6. Easy to Digest
  7. Low Glycemic

Ingredients for Healthy Sourdough Poptarts {Peanut Butter + Strawberry Jam}

Here’s what you’ll need to make these Healthy Sourdough Poptarts at home.

  • All-Purpose Flour: I used a local stone ground All Purpose Flour (because it’s the most nutritious!) However, King Arthur has a great organic all-purpose flour that I would recommend too.
  • Water: Preferably warm water is best! Warmer water helps kickstart fermentation.
  • Sourdough Starter: Be sure you are using active sourdough starter (not discard).
  • Salted Butter: I use salted pastured butter from Organic Valley but any butter will do!
  • Maple Syrup: Instead of cane sugar, we are going to use a touch of maple syrup to sweeten the dough.
  • Sea Salt: Enhances flavor (and nutrition) by slowing fermentation.
  • Peanut Butter: I love Trader Joe’s organic creamy peanut butter.
  • Strawberry Jam: I usually go for a high-quality organic jam but I also love to make homemade strawberry chia jam too if I have time!
  • Cinnamon: Cinnamon adds a hint of flavor to our poptart and is my favorite add-in to PB&Js.

Equipment Needed for Healthy Sourdough Poptarts

  • Mixing Bowl or Dough Mixer: You can prepare the Poptart dough with either a mixer or by hand. I mixed by hand!
  • Baking Pan
  • Baking Scale: ideal for accurately measuring ingredients

These healthy sourdough poptarts have a soft and flakey crust with gooey swirls of warm peanut butter and strawberry jam in every bite.



Sourdough Poptart Crust

  • 1 Cup Flour (120g)
  • 1/3 Cup Butter or Coconut Oil (70g)
  • 1/2 Cup Sourdough Starter (125g)
  • 1/2 TSP Salt (2g)
  • 2 TBSP Water (30g)
  • 2 TBSP Maple Syrup (30g)

Peanut Butter + Strawberry Filling (Per Poptart)

  • 1.5 TBSP Peanut Butter
  • 2 TBSP Strawberry Jam

Additional Ingredients

  • Cinnamon
  • Egg Yolk (for egg wash)


  1. MIX DOUGH AND FIRST RISE: In a bowl or stand mixer, add all ingredients and mix until a ball forms. Let the dough rise at room temperature for 6 – 8 hours or until it doubles in size.
  2. OVERNIGHT RISE: Place your dough covered in the fridge for an overnight proof. This is where your dough will develop flavor and L.A.B bacteria will get to work enhancing the nutrition of our dough. Remember, the longer we ferment the better for us it gets!
  3. ROLL OUT AND SHAPE: The next day, roll out the dough on a floured work surface. You want the dough to be about ⅛" thick. Cut the dough into 8 equal pieces. 
  4. ADDING FILLING: Add 1-2 TBSP of peanut butter and jam to 4 of the rectangles. And then place the other dough on top. Use a fork to press and seal the edges. Then, brush with egg wash and sprinkle cinnamon on top.
  5. BAKE: Preheat your oven to 350°F and line with baking sheet with parchment paper. Bake for 25 – 30 minutes or until golden brown.
