Someone will help specifically with a recipe. Until such time as that occurs try a Google search for "keto (low carb) cracker recipes" to find something to make or leave the word "recipe" off and you will discover pre-made things to order on line.

I've baked pepperoni or thinly sliced salami before to make something "cracker like" for cheese, guacamole, dips.

ETA: can also be done in the microwave in a few seconds.

you can buy pre-made cheese crisps made entirely of cheese. You can also make these in the microwave or in the oven.

I have used the fathead pizza crust recipe to try to make crackers. They tasted pretty good, but I couldn't get them crispy like crackers. I also added some extra seasoning such as garlic powder because otherwise they are kind of bland. If you are putting cheese or PB on them, that may not be an issue, though.

haha, a post in which I can be useful! I make these http://madeleineshaw.com/recipes/flax-seed-crackers-with-avocado-dip/
They are basically flaxseed and chia seeds. super easy to make (though they take time as they dry rather than bake). They are very, very tasty with cheese

Like someone mentioned above you can add small heaps of parmesan to a frying pan and it will make little crispy things. I also like pork crackling

I noticed I had to leave my fat head crackers out to dry before placing them in a storage container. They seemed to crisp up when left exposed to the air for awhile.

cheese crisps are great!

Here's something I've been making almost daily this past month. It's more of a bun than a cracker but very satisfying and filling. For extra crispiness, carefully cut one bun in half width-wise and toast. Note that it calls for a "muffin top pan" which isn't found in everyone's kitchen. If you're going to be making LC buns and flatbreads, it's worth ordering one; I got mine online from target.com.

Keto Flax Buns

Preheat oven to 325.

Combine
1 and one-half teaspoons dry minced onion
enough water to moisten
Leave to soften.

Combine
½ cup plus 1 tablespoon flax meal (I measure out 96 grams)
¼ cup plus 2 tablespoons shredded parmesan cheese (30 grams)
1 and one half teaspoons onion powder
¾ teaspoon baking powder
1 teaspoon granular sweetener of choice (I use Splenda)

Beat together
1 and one half tablespoons water
1 and one half tablespoons oil
3 eggs

Stir softened minced onion into egg mixture. Add egg mixture to dry ingredients. Stir to combine.

Spoon into greased muffin top pan, about ¼ cup per bun to make six buns. Bake for 15-17 minutes. Check at 15 for browning. Cool in pan 5 minutes, remove from pan to cool on rack.

Per bun:
2 net carbs (my calculation; the original recipe said "1.5 grams" which is just silly)
8 grams protein
