You might wonder why I have a gluten-free pumpernickel bread machine recipe on an RV site. The answer is simple: I can’t have gluten, but I love Reuben sandwiches, and for that, I need the bread.
Unfortunately, commercial, gluten-free pumpernickel bread is not available at any price. What’s a girl to do?
The Quest for Gluten-Free Pumpernickel Bread
After discovering that I am gluten-intolerant (if not celiac), I bought a bread machine, a gluten-free bread machine cookbook, and at least 47,000 GF flours, starches, leaveners, utensils, and everything else. Armed with these resources, I set to work to make gluten-free pumpernickel bread in the bread machine. Should be easy, right?
Well, my first try was a big flop!

Not one to be deterred, I tried the same recipe in the same machine but added a little more water. That loaf was almost edible.
Frustrated, I returned the first machine and purchased the best domestic bread machine money can buy. This one has two paddles and all kinds of other bells and whistles. I tried the original recipe in the new machine with slightly better results. It tasted good, but the top sank, and it fell apart in our Reubens.

When in Doubt, Do More Research
Getting a bit desperate after my third try, I contacted the bread machine company. They advised me how to alter my recipe and the machine settings, though they had never tested gluten-free pumpernickel bread in their machines. I tried again and got almost exactly the same results.
Still determined, I scoured the internet for days looking for a recipe, but nothing was quite right. I temporarily gave up and made a successful loaf of plain bread from the bread machine recipe book.
The Seventh Try is a Charm
Finally, although I had no idea what I was doing, I created a calculator that compares the ingredients of the successful, gluten-free plain loaf from the bread machine book to the unsuccessful, gluten-free pumpernickel loaf from the cookbook I bought.
It was tricky to compare the two recipes because the plain bread recipe was for a 2-lb loaf, and the pumpernickel recipe was for a 1.5-lb loaf. Unphased, I hacked out a gluten-free pumpernickel recipe based on the ingredients of the two completely different breads. Then, throwing caution to the wind, I tried it.
Successful GF Pumpernickel Bread at Last
The bread looked a lot different while it was in the machine. The rise was better, and best of all, it didn’t fall after baking. The ultimate test came after slicing and tasting it. We couldn’t tell the difference from the gluten-based pumpernickel bread we used to buy at the store!

I know how hard it was to find a good, gluten-free pumpernickel bread machine recipe, so I had to share. I hope you enjoy it!
Gluten-Free Pumpernickel with Bread Machine
Equipment
- Bread machine with two-pound loaf capacity
- Kitchen scale
- Instant-read thermometer
- Wire cooling rack
Ingredients
Dry Ingredients
- 1 TBSP Active dry yeast
- 280 g Buckwheat flour
- 182 g Potato starch
- 32 g Brown rice flour
- 32 g Sweet rice flour
- 7 g Tapioca flour
- 1½ tsp Kosher salt
- 2 tsp CocoaX unsweetened cocoa+espresso powder
- 1 tsp Onion powder
- 1 TBSP Caraway seeds
- 1 TBSP Xanthan gum
- ⅛ tsp Ascorbic acid
- 1 TBSP Brown sugar firmly packed
Wet Ingredients
- 360 ml Nonfat milk warmed to 80°F or 27°C
- 1 TBSP Apple cider vinegar shaken first if settled
- 4 TBSP Light olive oil not extra virgin
- 3 TBSP Molasses not blackstrap
- 3 large Eggs room temperature, beaten
Instructions
- Put the yeast in a small bowl and set aside.
- Whisk the remaining dry ingredients together in a large bowl.
- Add the warmed milk to a 4-cup measuring cup or a medium bowl. Add the oil to the milk, then add the molasses and whisk until well combined. Add the remaining wet ingredients and whisk again.
- Pour the liquid ingredients into the bread pan.
- Add the dry ingredients (excluding the yeast) to float on top of and completely cover the wet ingredients. Make a well in the center, and add the yeast.
- Put the bread pan in the machine, and choose the Gluten Free cycle with a medium crust.
- A few minutes after the machine reaches the kneading cycle, use a silicone spatula to gently push any flour stuck to the sides of the pan into the middle of the dough. Don’t open the lid during the rise or bake cycles.
- When the bake cycle is complete, verify that the inner bread temperature is at least 206°F on an instant-read thermometer. If it's not, leave it in the machine with the lid closed for a few minutes or bake in a 350°F oven until it reaches the correct internal temperature.
- Remove the pan using oven mitts, and gently slide the bread onto a wire cooling rack. Let it cool completely (at least two hours) before slicing.
