Microwave Baked Apple Peanut Butter Oatmeal (Without Sugar)

Microwave baked apple peanut butter oatmeal without sugar is perfect for one serving oatmeal in a single bowl that you can quickly and easily make in the microwave oven with all the deliciousness of apples and peanut butter! And you won't miss the sugar in this oatmeal as we try to make this oatmeal naturally sweet with apples baked in the microwave first! However, if you want more sweetness to the oatmeal, feel free to add a little honey or maple syrup or sugar (brown sugar or white sugar) as you prefer! This microwave baked apple peanut butter oatmeal makes the perfect, quick and easy oatmeal for serving that you can enjoy for breakfast or snack as you wish! Though this microwave apple oatmeal makes one large serving for a filling breakfast, this is also perfect for 2 small servings!

Also try this microwave oatmeal with apples and cinnamon (slightly different method), baked apple cinnamon oatmeal and also stovetop oatmeal with apples and cinnamon if you like the idea of apple oatmeal! I have this peanut butter oatmeal porridge in microwave as well if you want to try, as peanut butter oatmeal is super delicious whether you add apples or not, and the addition of peanut butter in your oatmeal is an easy way to add natural protein to your oatmeal (if you are not allergic to peanut butter)! However, when you do add apples and peanut butter together in your oatmeal, they add more nutrients and protein and also the flavors of baked apples and creamy peanut butter which makes the oatmeal even more delicious!

Honeycrisp, Fuji, Gala, Pink Lady, and Ambrosia apples are excellent choices because they are naturally sweet and become tender when cooked. Personally, I like to use pink lady, gala, honeycrisp or fuji apples for this recipe because they soften nicely in the microwave while keeping some texture and natural sweetness.

can you make oatmeal in microwave?

Yes! It's absolutely possible to make small servings of baked oatmeal in microwave oven and you can add ingredients like apples, peanut butter or other ingredients like bananas, blueberries etc. In fact, if you are making oatmeal just for yourself or your kids and you just need one serving or two servings of baked oatmeal, it is often easy to quickly prepare the oatmeal in the microwave oven than to use stove top or conventional oven as the microwave method is quicker and easier for small servings!

In fact, I have made apple cinnamon oatmeal in microwave before also but this recipe is more like baked apple oatmeal with peanut butter and it's quite different because we first cook the apple slices in the microwave before adding the oatmeal which really do make a difference in this recipe, whereas the other recipe is more simple with fresh apples added into the oatmeal after the oatmeal is almost cooked. So if you want the juicy, baked apple flavors in your oatmeal, do try this recipe, but if you prefer to add the fresh apples at the end of preparation you can follow the other recipe based on your preferences!

Also, in this recipe for microwave baked apple peanut butter oatmeal, we also add couple of tablespoons of peanut butter which adds even more taste and natural protein to your baked apple oatmeal!

Frequently Asked Questions

Can I make this oatmeal sweeter?

Yes! This recipe relies on the natural sweetness of baked apples, but you can add honey, maple syrup, brown sugar, or white sugar if you prefer a sweeter oatmeal. You may also use sweet apples such as Fuji, Gala, or Honeycrisp for extra natural sweetness.

What kind of oats work best for this recipe?

Old-fashioned rolled oats work best for this microwave baked oatmeal recipe. Quick oats can also be used, but the texture will be softer. Steel-cut oats are not recommended because they require a much longer cooking time.

Can I use milk instead of water?

Yes! You may replace all or part of the water with milk for a creamier oatmeal. Dairy milk, almond milk, oat milk, soy milk, or coconut milk all work well in this recipe.

Can I use crunchy peanut butter?

Absolutely. Both creamy and crunchy peanut butter work well. Crunchy peanut butter adds extra texture and a little more crunch to the finished oatmeal.

What apples are best for oatmeal?

Honeycrisp, Fuji, Gala, Pink Lady, and Ambrosia apples are excellent choices because they are naturally sweet and become tender when cooked. Granny Smith apples can also be used if you enjoy a more tart flavor.

Can I make this recipe vegan?

Yes. Simply use a plant-based milk such as almond milk, oat milk, or soy milk. The recipe is naturally dairy-free if you skip regular milk or use a dairy-free alternative.

Can I add other ingredients?

Yes! This oatmeal is very customizable. Try adding cinnamon, nutmeg, chopped walnuts, pecans, raisins, dried cranberries, bananas, blueberries, chia seeds, flax seeds, or a drizzle of maple syrup.

Can I meal prep this oatmeal?

Yes. Store leftover oatmeal in an airtight container in the refrigerator for up to 3 days. You can also freeze portions in freezer-safe containers for longer storage. Reheat in the microwave with a splash of milk or water before serving.

Why do I cook the apples first?

Cooking the apples before adding the oats helps soften them and creates a baked apple flavor throughout the oatmeal. This simple step gives the oatmeal a richer taste and a texture similar to baked apple desserts.

Can I eat this oatmeal cold?

Yes! You can enjoy it warm straight from the microwave or chill it in the refrigerator and enjoy it cold later as a quick breakfast or snack.

Recipe Tips

• Use a large microwave-safe bowl to prevent the oatmeal from boiling over.
• Rolled oats work best for this recipe and provide the best texture.
• Cook the apples first for a softer texture and a richer baked apple flavor.
• If the oatmeal becomes too thick, stir in a little extra milk before serving.
• For extra flavor, add a pinch of cinnamon, nutmeg, or apple pie spice.
