You’re going to love these mini gluten-free tarts. The shells are made with peanut butter and ground quick oats, filled with cinnamon-sugar baked apples, and drizzled with a maple-caramel glaze. In short, these tartlets are amazing.

I happen to LOVE apple pie, but it’s not something that works well with my meal plan. I wanted a gluten-free, whole-grain and naturally sweetened alternative that I genuinely enjoy, and these peanut butter apple-caramel tartlets check off all those boxes. While still a dessert, these mini-tarts are made with whole, refined sugar-free ingredients you can feel good about.

I used powdered peanut butter and pulverized oats for the tart crusts and added olive oil-butter blend baking sticks for moisture and fat. While made with healthier, gluten-free ingredients, these mini-tarts are just delicious as a traditional apple tart! Enjoy!

Why You’ll Love This Recipe

  • These tartlets are a healthier, gluten-free and single-serving alternative to apple pie.
  • Tartlets are the perfect elegant dessert for gatherings.
  • The added peanut butter truly sets these tartlets apart from the rest -the peanut butter pastry is perfect.
  • You can also make peanut butter-apple caramel tartlets with store-bought gluten-free pastry dough (or regular) to save yourself a few steps.

Ingredients You’ll Need


  • Quick Oats: become soft and tender much quicker than rolled or steel cuts, so you won’t need to bake the shells long.
  • PBFit Peanut Butter Powder: enhances the peanut butter flavor and gives these tartlets a nutritional boost.
  • Baking Soda & Baking Powder: help the pastry rise.
  • Salt: enhances the pleasantly sweet and sugary flavors.
  • Vanilla Extract: adds flavor and color.
  • Water: to moisten the dough.
  • Olive Oil Butter Blend Sticks (softened): You can also use EVOO, coconut oil or regular butter.
  • Maple Sugar (or brown sugar or coconut sugar): Maple sugar is a natural sweetener that gives these mini tarts a great caramelized flavor.
  • Egg: helps develop a sticky and cohesive gluten-free pasty dough.
  • Creamy Peanut Butter: strengthens the dough and deepens the peanut butter flavor.


  • Autumn Glory Apples (finely chopped): or honey crisp, Braeburn, pink lady. Be sure to use apples that won’t turn to mush under heat.
  • Cinnamon: flavors the filling with a bit of warming spice.

FOR THE DRIZZLE: you’ll need melted butter, maple sugar, and heavy cream. A few seconds in the microwave and these ingredients become transform into a sweet glaze perfect for drizzling over your homemade tartlets.

How To Make Apple Caramel Tartlets

Step 1: Preheat and prep the tart pan.

Preheat your oven to 350 degrees F and spray a 25-cup tart pan with cooking spray. Set aside.

Step 2: Grind oats.

Place oats in a food processor and grind them down into flour.

Step 3: Combine dry ingredients.

Add the ground oats, PBFit peanut butter powder, baking powder, and salt in a small mixing bowl. Whisk well to combine. Set aside.

Step 4: Blend wet ingredients.

In the bowl of an electric mixer, blend together the butter (or oil) and maple sugar until smooth. Add the egg, vanilla, and water and continue to mix until combined.

Step 5: Blend dry and wet ingredients.

Add the dry oat mixture to the bowl with the wet ingredients and blend on LOW speed until a sticky dough forms. Do not overmix.

Step 6: Drop dough.

Using tablespoon-size scoops, drop the dough in the prepared tart pan, dividing evenly between each cup. Flatten each ball of dough with a tart tamper.

Step 7: Bake.

Transfer the tart pan to your preheated oven and bake for 10 minutes or until the shells are firm and crumbly.

Step 8: Make cinnamon-apple filing.

While the shells bake, place the chopped apples in a microwave-safe dish sprinkled with cinnamon and microwave for 3 to 4 minutes or until the apples are soft and fragrant. Stir the apples and set them aside.

Step 9: Fill shells with filling:

After pulling the tart shells from the oven, press down on each with the tart tamper to make a well for the cinnamon-apple filling. Then, spoon the apple filling into each of the wells.

Step 10: Make drizzle and serve:

In a small microwave-safe dish, add a tablespoon of butter, 2 tablespoons of maple sugar and a splash of cream—microwave on LOW for 10 seconds. Immediately drizzle over peanut butter-apple caramel tartlets and serve!

Recipe Tips

  • Squeeze lemon juice over the apples after you chop them to keep them from browning as quickly.
  • Reserve some of the maple sugar to sprinkle over the drizzle.
  • Microwave caramel chips with the apples and cinnamon to make the filling caramel-y and delicious.


Now that you have a tried and true gluten-free peanut butter tartlet shell recipe, the filling opportunities are practically endless. Instead of apples, try filling your mini-tarts with:

Storing & Freezing

Storing: Before storing, let the tartlets cool on a wire rack to room temperature and then wrap each one securely in plastic wrap and keep it in the fridge for 3 to 4 days.

Freezing: Let tart shells cool on a wire rack for at least an hour. If not serving right away, wrap each tart crust in plastic wrap and store them in a freezer-safe container for up to 3 months. Defrost at room temperature and then add your filling.

Recipe FAQ

What makes a dessert a tart?

Tart shells are made with a pastry dough that becomes firm and crumbly when baked. The crusts have sturdy bottoms and shallow sides and can be filled with a variety of sweet and savory fillings. Unlike pies, tarts do not have a top layer of crust.

Can I make apple caramel tartlets ahead of time?

You can make the dough in advance and have it pressed and ready to be baked and filled with apples and drizzle.

Can I make tartlets with store-bought pastry dough?

Yes, if you’d rather use pre-made pastry dough, you can. However, you may need to adjust the cooking time to adapt to the different densities.
